[00:00:52] <stevegt_> LawrenceSeattle: cncrouterparts.com has open-source designs
[00:01:21] <stevegt_> they use colled-roll steel and 80/20 for the slides as well
[00:01:28] <stevegt_> cold-roll
[00:01:43] <stevegt_> cold-rolled, arg
[00:02:01] <LawrenceSeattle> ah nice
[00:02:15] <LawrenceSeattle> this one? http://www.kronosrobotics.com/krmx02/index.shtml
[00:02:20] -!- vladimirek has quit [Read error: Operation timed out]
[00:02:40] <LawrenceSeattle> damn 400lb
[00:02:48] <ReadError> makerslide looks nice
[00:03:30] <stevegt_> actually, the cncrouterparts slide looks cheaper to make than the makerslide design, and should be as accurate
[00:04:59] <LawrenceSeattle> was also looking at the zentools kits. I'd prefer something 12x12"

[00:10:16] <Jymmm> LawrenceSeattle: as in escaped canuck?
[00:13:04] <stevegt_> LawrenceSeattle: yes, and here's their page for the kronos kit: http://www.cncrouterparts.com/krmx02-parts-bundle-p-153.html?cPath=29
[00:13:04] <LawrenceSeattle> heh
[00:13:35] <LawrenceSeattle> nice looking cnc. Overkill for me though
[00:13:45] <Jymmm> LawrenceSeattle: They let you across the border, or did you take one of those back road crossings?
[00:14:13] <stevegt_> LawrenceSeattle: you might be surprised -- remember, if you get, say, a 2'x2' machine, it can make cases as well
[00:14:28] <stevegt_> i think you'll be cramped on a 12x12
[00:14:31] <LawrenceSeattle> stevegt_: true
[00:14:46] <LawrenceSeattle> shop space is at a premium though
[00:16:03] <Thetawaves> i am cramped on 20cmx30cm
[00:16:10] <stevegt_> LawrenceSeattle: tell me about it. I've got my whole sherline setup, with flood cooling, enclosure, and everything, crammed onto a 2'x3' harbor freight cart. ;-)

[00:17:26] <Jymmm> doens't sound like a bad way to go other than HF
[00:17:37] <stevegt_> Thetawaves: that's a little small -- not much bigger than a mini mill
[00:17:38] <Jymmm> cq cq cq dx
[00:17:57] <Thetawaves> yes it is tiny.
[00:18:07] -!- asdfasd has quit [Ping timeout: 264 seconds]
[00:18:18] <LawrenceSeattle> I need to find a ME type to partner up with really. I can do the electronics/coding
[00:18:33] <stevegt_> Jymmm: the HF 2x3' cart is a good strong cart -- it falls into the category of "they lucked out on that design" ;-)
[00:18:50] <alex4nder> stevegt_: I'm doing something similar but with an 80/20 cart
[00:18:53] <alex4nder> and a taig
[00:19:11] <Jymmm> stevegt_: Ah, ok. Else I'd ecommend a rubbermaid if you can afford one.
[00:19:34] <Jymmm> stevegt_: damn things are very cool, but damn expensive
[00:19:46] <stevegt_> alex4nder: I've debated "upgrading" to either 80/20, unitrut, or just get a big toolchest on wheels so I've got good storage for bits and jigs etc.
[00:20:03] <alex4nder> yup, all good options
[00:20:19] <stevegt_> unistrut
[00:20:21] <alex4nder> the toolchest would be nice, but I'd have a rough time justifying it unless I got something like a used Lista.
[00:23:22] <joe9> alex4nder: where do you find the taig spec to figure out the speed settings, etc?
[00:23:35] <stevegt_> LawrenceSeattle: I've gotten spoiled by having access to a friend's epilog laser -- if I didn't have that, I'd want at least a 18"*24" CNC router for panel-cutting etc. And of course the router can cut sheet aluminum and the laser can only do acrylic and thin wood
[00:23:47] <joe9> i think HF has a 25% sale this weekend.

[00:26:32] <joe9> alex4nder http://www.super-tech.com/root/grp.asp?p1=micromill-tooltips good one?
[00:26:42] <alex4nder> yah, that's fine
[00:27:29] <alex4nder> I only really use 1k, 3k, and 10k
[00:27:50] <stevegt_> Jymmm: I'd be afriad of putting this much weight on a composite cart like the rubbermaid -- the sherline (which is extra heavy because of the big motors and rotary table I've added), 5 gallons of coolant, and a couple of 2"x18"x18" concrete slabs to keep the sherline out of the soup. I'd be afraid a plastic cart would start to slump after a few months of that.
[00:29:37] <ve7it> Jymmm, there is an imposter lurking....
[00:30:29] <stevegt_> I keep expecting one of the little 1/4-20 bolts that holds the HF cart together is going to go *pop*, followed shortly by the others, but so far so good ;-)

[00:53:01] <joe9> or, cui, to be precise?
[00:53:20] <pfred1> never heard of it
[00:53:50] <pfred1> is it a window manager?
[00:54:55] <Jymmm> ve7it: I'm not sure, do you have a double?
[00:56:09] <ve7it> Jymmm, doppleganger maybe

[00:56:45] <Jymmm> scary
[00:57:23] <Jymmm> ve7it: check PM
[00:58:34] <joe9> pfred1: i am reading up the linuxcnc documentation. it is similar to the axis gui.
[00:58:51] <pfred1> joe9 oh a front end
[01:02:57] * pfred1 fixed his PC with bar lube
[01:03:57] * Tom_itx believes that
[01:04:22] <pfred1> the PSU fan was making these terrible sounds a couple drops of bar lube good as new!
[01:05:13] <pfred1> of course i had to void its non existent warranty in order to do so
[01:05:45] <joe9> is there something better than this http://wiki.linuxcnc.org/cgi-bin/wiki.pl?QuickStart
[01:05:57] <joe9> i am looking to start using linuxcnc and am reading up the manual.
[01:06:14] <joe9> i just want to start one axis motor, move from end to end
[01:06:31] <joe9> and, then do the same thing with the other 2 axes.
[01:06:51] <joe9> just move from end to end.
[01:07:26] <joe9> pfred1: one of my car pulleys is making a lot of noise when humid. need to fix that. will see if bar lube might help there.
[01:07:48] <pfred1> sure it isn't the belt?
[01:08:10] <pfred1> sometimes they or the pully itself get glazed
[01:08:23] <joe9> oh, never thought of the belt.
[01:08:39] <joe9> it makes the whiny noise when rainy or after the rain.
[01:08:42] <pfred1> yeah try sanding it while it is running like tape some sandpaper to a stick of wood
[01:09:16] <pfred1> just to break the glaze like don't go nuts
[01:10:03] <pfred1> but if the belt is all cracked and stuff just change it but maybe scuff the pulley a little
[01:11:47] <pfred1> joe9 whatever you do don't get any bar lube on the belt!
[01:12:15] <joe9> oh, ok. thanks.
[01:12:42] <pfred1> they make a stick of this crap called belt squeak stop but I think sanding them is better
[01:12:50] <joe9> pfred1: are you aware of any "quick start" guide for linuxcnc?
[01:13:22] <Tom_itx> dive in head first
[01:13:31] <pfred1> what I did was open a front end then file : open then navigate ot the examples directory
[01:13:53] <Loetmichel> sooo, first bearing block done. Tomorrow i will make the second (its 03:13 over here) http://www.cyrom.org/palbum/main.php?g2_itemId=13033
[01:13:56] <pfred1> sort of the same thing I do with every program
[01:14:19] <pfred1> axis is cool there
[01:16:19] <pfred1> Loetmichel are those the cheap Horrible Fright digital calipers?
[01:16:54] * pfred1 has those
[01:17:15] <pfred1> like if you turn it on does it start off at zero no matter where the jaws are?
[01:18:37] <joe9> Tom_itx: tried that approach. I could not figure out what was going on.
[01:19:13] <pfred1> joe9 you have to estop off machine on then home all of your axises
[01:19:41] <joe9> pfred1: estop is F1, correct? (from the manual).
[01:19:49] <pfred1> I donno i use the menu
[01:19:51] <joe9> and then just move the axis from one end to the other.
[01:20:21] <pfred1> but once you do all of that it starts working
[01:20:39] <pfred1> like how you may thnk it would
[01:20:52] <pfred1> until you do that though it just errors
[01:22:27] <alex4nder> gentlemen
[01:42:21] <joe9> nothing happens when I press "Toggle Emergency stop" http://codepad.org/kRUs0f2f is from my kernel.
[01:42:40] <joe9> looks like linuxcnc is sending the correct message (or, is it not?)
[01:42:47] <joe9> Apr 6 21:36:24 firefox kernel: [ 139.237560] config string '0x378 out '
[01:42:59] <joe9> is what makes me think that something might be off in my configuration.
[01:43:10] <pfred1> you machine's name is firefox?
[01:43:15] <joe9> yes
[01:43:17] <Tom_itx> do you have limits that aren't hooked up yet?
[01:43:36] <pfred1> 0x378 is parallel port's standard address
[01:43:51] <Tom_itx> so is 0x278
[01:44:14] <pfred1> 0x378 much more common 0x278 is the secondary
[01:44:26] <Tom_itx> agreed
[01:44:46] <pfred1> that doesn't look like an error to me I don't know
[01:45:31] <pfred1> joe9 if you want to get really paranoid sudo tail -f /var/log/syslog in a terminal :)
[01:46:31] <joe9> is there a debug mode for linuxcnc?
[01:47:43] <joe9> or, atleast a command line mode?
[01:47:45] <pfred1> I think you'd have to build it with debugging symbols
[01:47:49] <joe9> oh, ok.
[01:47:52] <cradek> what are you trying to do?
[01:48:17] <pfred1> cradek I think joe9 has to switch to the decaff
[01:48:42] <joe9> cradek: i am just trying to use the machine from linuxcnc.
[01:49:00] <joe9> i read from the manual that the first step is to toggle Estop
[01:49:18] <pfred1> turn it off
[01:49:34] <pfred1> linuxcnc starts out with estop on
[01:50:13] <pfred1> joe9 then you have to turn the machine on
[01:51:11] <joe9> i had the machine on before I started linuxcnc program.
[01:51:28] <pfred1> no you have to turn the machine on in linuxcnc
[01:51:38] <joe9> and, the hardware estop on the machine is off/disengaged.
[01:51:54] <pfred1> ok is the machine on in linuxcnc?
[01:51:59] <joe9> no
[01:52:12] <joe9> linuxcnc cannot even see the machine, it appears to me.
[01:52:29] <pfred1> of course it can
[01:52:30] <pfred1> 't
[01:53:29] <joe9> the GeckoG540 has a green light
[01:53:41] <pfred1> you have ot turn the machine on in linuxcnc
[01:53:42] <joe9> so, that means that linuxcnc is communicating with the Gecko.
[01:53:56] <joe9> pfred1: i agree.
[01:54:10] <joe9> but, the first step seems to be to "toggle Estop" before turning the machine on.
[01:54:24] <joe9> from linuxcnc
[01:54:31] <joe9> http://www.linuxcnc.org/docs/2.5/html/gui/axis.html
[01:54:41] <joe9> 2.1. A Typical Session
[01:55:21] <joe9> cradek, i set up the taig machine that i bought with Gecko G540 and 3 stepper motors on each axis.
[01:55:59] <joe9> cradek: the G540 has a green light on, with the "charge pump" on.
[01:56:13] <joe9> and, now I am trying to move the axes from linuxcnc.
[01:56:41] <joe9> with linuxcnc, I start it using the command "linuxcnc" after running the "../scripts/rip-environment".
[01:56:55] <joe9> linuxcnc programs starts fine and shows me the "Axis" gui.
[01:57:14] <joe9> All the options in the Manual tab (F3) are disabled.
[01:57:30] <joe9> Pressing F3 does not do anything.
[01:57:43] -!- GoSebGo has quit [Quit: Bye]
[01:57:44] <joe9> I read from the manual that the first step is to toggle Estop.
[01:57:57] -!- GoSebGo [GoSebGo!~GoSebGo@184-229-35-132.pools.spcsdns.net] has joined #linuxcnc
[01:57:59] <joe9> I try that from both the icon and menu item, but, nothing happens when I do that.
[01:58:44] <joe9> and, at the bottom of the "Axis" gui window, it says "ESTOP No Tool Position: Relative Actual"
[01:59:04] <alex4nder> what happens why you try to move an axis?
[01:59:08] <pfred1> joe9 the same menu where yo uturned estop off there should be machine on
[01:59:48] <joe9> The "Turn Machine Power (F2)" is disabled.
[02:00:49] <joe9> with the debug level, this is what I get :
[02:00:51] <joe9> http://codepad.org/mpmSu6MY
[02:01:30] <joe9> when I press "Toggle Emergency Stop" menu item.
[02:02:17] <joe9> this is the "Show Linuxcnc status" http://codepad.org/SySbdxQ0
[02:03:47] <joe9> this is my linuxcnc startup http://codepad.org/bISi3L8c
[02:04:10] <joe9> cradek, any more info I can provide?
[02:04:20] <pfred1> joe9 take a screenshot of your session
[02:05:00] <pfred1> exit linuxcnc restart it and just hit estop once
[02:05:28] <pfred1> because if you hit it an even number of tomes you're in estop mode
[02:05:57] <joe9> this is my taig.ini: http://codepad.org/uH0zKxi7
[02:07:12] <joe9> pfred1: restarting it, seemed to help.
[02:07:28] <pfred1> cool just hit estop once
[02:07:37] <pfred1> now find machine on
[02:07:48] <pfred1> because until you turn it on in the software it won't do anything
[02:08:06] <joe9> no, same behaviour.
[02:08:18] <pfred1> you turned it on?
[02:08:41] <pfred1> even after you turn it on it still won't do anything
[02:08:42] <joe9> no, hitting ESTOP does not change anything.
[02:08:47] <pfred1> you have to home each axis
[02:08:57] <pfred1> what are you expecting to change?
[02:09:01] <joe9> pfred1: no, I cannot even get there.
[02:09:14] <joe9> when it starts, the ESTOP is on
[02:09:18] <joe9> and I cannot change it.
[02:09:20] <pfred1> yes turn it off
[02:09:31] <joe9> nothing happens when I click on it.
[02:09:34] <pfred1> then you must have something messed up in your config
[02:09:44] <joe9> yup, that is possible.
[02:09:51] <joe9> i think I did the ESTOP pin wrong.
[02:09:55] <joe9> or something like that.
[02:09:57] <alex4nder> I would recommend getting a beer.
[02:09:59] <pfred1> it expects a signal at an input and you have the wrong one like you have a physical estop switch engaged
[02:10:18] <alex4nder> how did you wire your estop switch with the G540?
[02:10:58] <pfred1> you have to reverse whatever the config file says if yo ucannot disengage estop you can't do anything
[02:11:30] <pfred1> the software thinks the machine is grinding a human being up and blood is up and down the walls
[02:11:45] <joe9> ground to switch to pin 10. that worked, I checked it with the gecko feature (disable charge pump, estop on, red light, estop off, green light)
[02:12:21] <alex4nder> well it worked for the G540, but what does linuxcnc think the status is?
[02:12:46] <pfred1> alex4nder the polarity has to be wrong
[02:12:49] <joe9> this is my taig.hal: http://codepad.org/Twaz6Vfl
[02:12:54] <alex4nder> pfred1: that's what I'm thinking
[02:13:14] <pfred1> joe9 can you turn your estop switch on?
[02:13:17] <joe9> that is probable, the Gecko G540 expects ground when Estop is off.
[02:13:39] <pfred1> just to see if you can disengage estop in the software
[02:13:40] <joe9> when I do that, the G540 goes to red light.
[02:13:44] <pfred1> so
[02:13:49] <pfred1> I don't care about that now
[02:13:56] <pfred1> I want to see if yo ucan get linuxcnc out of estop
[02:14:05] <joe9> ok, let me try tha.
[02:14:13] <joe9> s/tha/that.
[02:14:14] <pfred1> one step at a time
[02:14:35] <pfred1> if yo ucan the nthat confirms a misconfiguraiton
[02:16:03] <joe9> pfred1: you are correct
[02:16:09] <pfred1> ok
[02:16:22] <pfred1> grep -in estop * in yoru config dir
[02:16:34] <joe9> when I have the Estop switch on, the linuxcnc came out of the ESTOP mode.
[02:16:36] <pfred1> because i really have no idea what the line is
[02:16:52] <pfred1> yes yo uneed to switch it in your configfile
[02:19:22] <joe9> http://codepad.org/iRVq2XZb
[02:19:27] <joe9> is the result of the grep
[02:20:09] <pfred1> the line numbers might have helped
[02:21:43] <pfred1> joe9 I see estop mentioned but no line is standing out that sets the polarity to me
[02:22:27] <pfred1> joe9 btw the n switch in grep gives you the line number displayed
[02:23:28] <pfred1> if i had to bet I'd say it is the last line?
[02:24:20] <pfred1> joe9 http://linuxcnc.org/docs/html/man/man1/io.1.html
[02:24:29] * pfred1 is a good guesser :)

[02:33:34] <joe9> pfred1: yes, sorry, had issues with irc there for some time.
[02:33:39] <joe9> net estop-ext <= parport.0.pin-15-in <
[02:33:43] <joe9> is my problem.
[02:33:49] <joe9> i need to get rid of that line
[02:34:06] <pfred1> joe9 this looks like what you need to do linkpp parport.0.pin-15-in-not iocontrol.0.emc-enable-in
[02:34:09] <joe9> net estop-ext => iocontrol.0.emc-enable-in >> net estop-out => iocontrol.0.emc-enable-in
[02:34:17] <joe9> change the above line
[02:34:23] <pfred1> no leave that line alone add the other one
[02:35:04] <pfred1> then turn your estop switch off
[02:35:18] <pfred1> like on your machine
[02:35:58] <pfred1> or wait first grep for linkpp in yoru config file see if it is there already
[02:36:01] <joe9> the G540 says that pin 15 is "FAULT (input to PC)"
[02:36:13] <joe9> and, I set that to ESTOP
[02:36:16] <pfred1> talk to mariss about that
[02:36:25] <pfred1> they're his drives
[02:36:38] <joe9> alex4nder uses the same setup that I had and his config is different on that line.
[02:36:51] <joe9> he does not have that estop-ext line
[02:37:23] <joe9> or, maybe, I can just invert that estop-ext line.
[02:37:38] -!- Valen has quit [Quit: Leaving.]
[02:37:39] <pfred1> the command I gave you should do that
[02:37:41] <joe9> add an "invert = 1"
[02:37:44] <joe9> oh, ok.
[02:37:45] <pfred1> no
[02:37:54] <joe9> got it. thanks.
[02:38:31] <alex4nder> I live dangerously.
[02:38:35] <pfred1> then restart linuxcnc and we'll see what happens

[02:40:20] <jdhnc> why can't he.
[02:40:24] <pfred1> beats me
[02:40:30] <joe9> pfred1: that is how I got this config file.
[02:40:36] <joe9> pfred1: i used stepconf
[02:40:49] <joe9> from the linuxcnc cd.
[02:41:02] <pfred1> oh then get that line out and run stepconf you can invert stuff there

[02:41:34] <joe9> ok, thanks.
[02:41:45] <pfred1> load your config file and use stepconf to fix it

[02:43:18] <pfred1> linuxcnc is awfully boring with estop engaged all the time
[02:45:05] <jdhnc> I need some 0.375" black delrin, any good (cheap) sources?
[02:45:57] <pfred1> jdhnc I'm glad we got that cleared up
[02:47:07] <jdhnc> never hurts to ask.
[02:47:17] <pfred1> can't use seaboard huh?
[02:47:41] <jdhnc> that's what I used first time. I think Delrin will be better.
[02:47:52] <pfred1> it'd better be
[02:50:23] <jdhnc> http://tinyurl.com/7h4dmvs
[02:50:43] <jdhnc> it's the part with the textured surface
[02:50:57] <pfred1> that scuba gear?
[02:51:01] <jdhnc> yeah
[02:51:23] <pfred1> you'd think seaboard would be good in the water ;)
[02:51:55] <jdhnc> it works fine, I just don't like the texturing
[02:52:03] <pfred1> polish it
[02:52:16] <jdhnc> I'd rather just buy some delrin
[02:52:34] <jdhnc> there are a few other things I'd like to remake with delrin also.

[02:54:12] <ssi> do you really need sheet?
[02:54:19] <ssi> strips would be easir probably
[02:54:26] <ssi> 3/8" thick by 1" wide by 1' is like $4
[02:54:33] <jdhnc> no, 2.5" wide would cover what I need.
[02:55:11] <ssi> to make http://tinyurl.com/7h4dmvs
[02:55:12] <ssi> ?
[02:55:17] <ssi> that looks more like 1" wide
[02:55:22] <ssi> if that
[02:55:28] <ssi> oh wait
[02:55:31] <ssi> I see the part you're talking about
[02:55:33] <jdhnc> 1.6" wide for that one.

[03:05:51] <jdhnc> I'm pretty sure if I just buy a small piece, I will screw itup.
[03:07:31] <pfred1> it comes from Niagra falls
[03:10:10] <jdhnc> I offered him $16 for two 4.6x5.8
[03:10:29] <pfred1> its all stuff he is dumpster diving for I bet he'll take it
[03:10:58] <joe9> pfred1: now, I have the icons enabled in linuxcnc.
[03:11:23] <joe9> pfred1: I press "Home Axis" and nothing happens. What should I be doing to move the X-axis from end to end.
[03:11:36] <joe9> pfred1: if you do not mind answering.
[03:11:37] <pfred1> joe9 you got out of estop?
[03:11:46] <joe9> pfred1: yes. the machine is on, now.
[03:12:02] <jdhnc> can you jog it?
[03:12:04] <pfred1> ok now you should be able to jog your axises
[03:12:24] <pfred1> you have to be in manual mode though
[03:13:47] <pfred1> jdhnc before their estop in was inverted they couldn't even get out of estop
[03:14:07] <pfred1> talk about a non-starter
[03:15:44] <joe9> pfred1: how do i jog the axis? I am in the "Manual Control [F3]" and i set the axis to X, and the movement to 5mm or such. and when I press "Home Axis", nothing happens.
[03:16:04] <jdhnc> press left/right or up/down
[03:16:08] <pfred1> your display should 0
[03:16:15] <pfred1> that is all home axis does
[03:16:25] <joe9> oh, ok. thanks.
[03:16:38] <pfred1> it doesn't make the machine move ot where it thinks home is
[03:16:48] <jdhnc> if you have no home switches, telling it to home just sets it homed.
[03:16:54] <pfred1> well maybe if you have homing switches it does
[03:17:12] <joe9> oh, ok. thanks. I was expecting something to happen there. that clears it up.
[03:17:16] <joe9> i do not have home switches
[03:17:28] <pfred1> nope just makes the machine think where it is is home
[03:17:38] <pfred1> you can rehome anytime
[03:17:54] <pfred1> but in order to run a program all axises have ot be homed
[03:18:39] <pfred1> I use the mouse I don't know what the keyboard commands are
[03:19:32] <joe9> that is cool. tha axis moves now. jdhnc, pfred1: thanks for your help.
[03:19:46] <pfred1> you're welcome I guess you did it though
[03:19:54] <pfred1> congratulations!
[03:20:12] <alex4nder> next phase: now wut?
[03:20:23] <pfred1> drink heavily
[03:20:27] <alex4nder> yah
[03:20:31] <alex4nder> that's what I'm doing
[03:21:00] <pfred1> that is what i should have done today
[03:21:07] <joe9> how do I move the z-axis?
[03:21:08] <pfred1> all I did was fix one PC and break another
[03:21:22] <joe9> left/right for x-axis, top/bottom for y-axis.
[03:21:23] <pfred1> go to it in the numbers
[03:21:30] <pfred1> then it is the active axis for manual control
[03:21:34] <jdhnc> page-up/down for Z
[03:21:39] <joe9> oh, ok. thanks.
[03:22:11] <pfred1> nothing like getting to play with your new toy
[03:22:22] <jdhnc> sorry, that was too easy.
[03:25:17] <joe9> it is pretty moody though. it works on one press of the Pgup/top/left and moves the axis once and maybe twice and then does not do anything.
[03:25:37] <jdhnc> is it set for distance or continuous?
[03:25:40] <pfred1> you might be at the end of your move
[03:25:53] <pfred1> or yeah you might be moving incrementally
[03:26:24] <pfred1> you can set the rate too your IPS
[03:26:32] <joe9> the distance is set for "continuous"
[03:26:44] <jdhnc> if you homed it at a non-home spot, it will probably only move one direction
[03:27:09] <pfred1> well you can override your limits your soft limits
[03:27:10] <jdhnc> depending on where you told it home was relative
[03:27:37] <jdhnc> bring Z up safe, touch-off, try to run tux
[03:27:58] <pfred1> yeah load a program
[03:28:44] <pfred1> that is when linuxcnc is cool
[03:29:01] <joe9> i can see more axis nut thread on the z-axis, but, pressing Pg-up does not do anything.
[03:29:22] <pfred1> you might be at your soft limit
[03:29:32] <pfred1> rehome
[03:30:03] <pfred1> just that axis
[03:30:30] <pfred1> I fiddles with my soft limits for a while
[03:30:35] <joe9> pfred1: that helped. thanks.
[03:30:38] <pfred1> np
[03:30:46] <joe9> yes, linuxcnc is cool.
[03:30:52] <pfred1> yeah you're going to have to work out what your limits really are
[03:31:02] <joe9> ok, will do.
[03:31:13] <joe9> is it something in the config files created by stepconf?
[03:31:18] <pfred1> yup
[03:31:34] <pfred1> on each axis window it lets you set your limits
[03:32:15] <pfred1> or you could find them in the ini file
[03:32:26] <pfred1> they're just numbers
[03:33:30] <pfred1> I had to set my z axis to a negative number some programs expect it
[03:33:37] <pfred1> or yo uget an out of range error
[03:34:08] <pfred1> there is probably an offset command that fixes that but I've no idea what it is
[03:34:09] <jdhnc> I use 0 as top of work, cuts are negative into the material
[03:35:17] <joe9> with the Z-axis, I see almost 2-3 inches of axis thread on top, but, after re-homing, it still does not move to the top.
[03:35:38] <pfred1> then keep rehoming that axis
[03:35:46] <pfred1> you are hitting your soft limit
[03:36:00] <joe9> i did that. it just does not move up at all.
[03:36:15] <jdhnc> does it move down?
[03:36:36] <pfred1> good question
[03:36:38] <joe9> let me check.
[03:37:12] <joe9> nope, no movement at all.
[03:37:17] <pfred1> not good
[03:37:27] <pfred1> check your wiring
[03:37:49] <pfred1> turn power off
[03:38:01] <pfred1> do not pull a stepper motor wire off with power to your drive
[03:38:11] <jdhnc> did it move when you exercised the axis while running stepconf and setting max speed/accel??
[03:38:43] <joe9> let me test another axis.
[03:39:46] <pfred1> if you ever pull a stepper motor wire off with power to your driver it is almost certain driver death
[03:39:50] <joe9> even the x-axis does not move. when I press the <- / ->, the X in the Preview does move by a very little. 0.033 to 0.019
[03:40:30] <joe9> oh, really. not sure if i did that.
[03:40:37] <pfred1> when yo uwere in stepconf did yo ucheck your axises?
[03:40:52] <pfred1> yeah don't ever pull a motor wire off your drive with it powered up
[03:41:00] <jdhnc> did you set speed/accel in stepconf? Did you move the axis in stepconf?
[03:41:19] <joe9> i did the "test axis" -> run, but, nothing else.
[03:41:37] <jdhnc> did they move then?
[03:41:46] <pfred1> a window pops up in stepconf and it lets you jog each axis
[03:41:58] <joe9> let me do that again. my issue is stepconf does not run on my cpu, have no idea why. everytime I have to use stepconf, I have to use the cd and reboot the linuxcnc pc.
[03:42:15] <joe9> jdhnc: yes, they moved with test axis -> run.
[03:42:26] <joe9> let me go back to stepconf and do that stuff again.
[03:42:38] <jdhnc> I'd suggest installing the livecd alongside your current install.
[03:42:48] <pfred1> yeah I did that a lot of times to get my acceleration and stuff right
[03:42:55] <jdhnc> unless you are just in to self-flagellation
[03:43:10] <joe9> jdhnc: my problem is when I install it, I have latency issues
[03:43:23] <jdhnc> if stepconf doesn't run, who knows what else won't work properly.
[03:43:24] <joe9> jdhnc: something to do with the pata_amd hard disk driver.
[03:43:26] <pfred1> smi?
[03:43:34] <pfred1> ah
[03:43:37] <jdhnc> got a spare SATA drive?
[03:43:55] <jdhnc> $150 and you get a low-latency atom box
[03:44:04] <pfred1> I wonder if they can run a different kernel disk driver
[03:45:25] <pfred1> blacklist that module
[03:46:36] <pfred1> I hear some filesystems can cause latency too the journaling ones
[03:47:21] <joe9> http://codepad.org/W0dSEPfT my latency observations/notes
[03:48:21] <pfred1> joe9 you might be able to get away with using a different kernel driver for your disks
[03:48:45] <joe9> pfred1: tried all that, man. all dead-ends.
[03:48:49] <pfred1> lsmod when you're in the CD
[03:48:59] <joe9> the only thing that worked is using a ramdisk.
[03:49:00] <pfred1> well why does the CD work?
[03:49:11] <joe9> it does not. just the stepconf works.
[03:49:26] <pfred1> then setup your other box to ramdisk
[03:49:35] <pfred1> you can load off the HDD but then ramdisk
[03:49:54] <joe9> that is what I currently have on the linuxcnc pc.
[03:50:00] <pfred1> k
[03:50:05] <joe9> but, in that setup, for some reason stepconf does not work.
[03:50:09] <joe9> have no idea why.
[03:50:13] <pfred1> then rmmod the driver that gives your problems
[03:50:48] <joe9> the rootfs is on that harddisk, so, it is built in.
[03:50:54] <joe9> to the kernel, I mean.
[03:51:09] <pfred1> the kernel loads to memory on boot
[03:51:29] <joe9> actually, yes, you have a point.
[03:51:31] <pfred1> it only goes back to the HDD to get modules
[03:51:51] <pfred1> you could erase your HDD and linux will still run
[03:51:56] * pfred1 has done this ...
[03:53:00] -!- sumpfralle has quit [Ping timeout: 260 seconds]
[03:53:28] <pfred1> of course when you shut your PC down don't expect linux to run the next time you start it
[03:54:13] <joe9> is this still a good configuration for stepconf for G540? http://www.onel.se/all_files/gecko_g540.html
[03:55:02] <joe9> i could package that module into the initial ramdisk and then load it, read the ramdisk, load the ramdisk as rootfs, rmmod the module and get over it.
[03:55:17] <pfred1> joe9 I see you played around some with hdparm
[03:55:19] <joe9> but, I am not sure if that module is the cause of stepconf issue from ramdisk.
[03:55:40] <joe9> pfred1: yes, could not change any of the dma settings. they are set in bios.
[03:55:49] <joe9> and changing them in bios was not helping.
[03:56:04] <pfred1> thats funny I trashed one of my HDDs setitng my dma incorrectly with hdparm once
[03:56:12] <joe9> the linux kernel trace points out that the ata functions were somehow blocking the rtapi.
[03:56:20] * pfred1 did not have a 133 system
[03:56:55] <pfred1> but hdparm happily set it for me just the same
[03:57:23] <pfred1> man that disk got trashed in a heartbeat
[03:59:05] <pfred1> what you need to do is diff your kernel config with one that works
[03:59:25] <pfred1> though plain diff won't really tell you
[03:59:38] <pfred1> so you have to grep every parameter
[03:59:52] <ReadError> how well do you think a 2.4ghz intel core2duo w/ 4gb ddr2 would do ?

[03:59:58] <ReadError> or should i get the atom
[04:00:10] <jdhnc> depends on the board

[04:00:54] <ReadError> sad panda ;*(
[04:01:04] <ReadError> i want one for form factor though too

[04:02:24] <ReadError> well
[04:02:31] <ReadError> i want to do it proper
[04:02:40] <ReadError> so it sounds like i need an atom setup
[04:02:43] <pfred1> because a dragster burns 24 gallons to the mile

[04:04:07] <pfred1> alex4nder the one I'm using now came out of a trash pile
[04:04:09] <joe9> the good news is all the axes test fine with "Test Axis" -> Run.
[04:04:28] <pfred1> joe9 then it is just a setting in your front end
[04:04:38] <alex4nder> what's the issue?
[04:04:42] <pfred1> did you set your limits?
[04:04:59] <pfred1> the stock limits are pretty conservative if memory serves
[04:05:22] <joe9> the Table Travel for my X and Y axis is -1000 to 1000, where as for the Z-axis, it is -100 to 100.
[04:05:25] <joe9> is that ok.
[04:05:32] <pfred1> k
[04:05:33] <ReadError> alex4nder
[04:05:41] <ReadError> you use one of those pendants ?
[04:05:48] <alex4nder> I use a playstation 3 controller
[04:05:50] <ReadError> seems like it would be ideal for manual work
[04:05:53] <ReadError> super low res
[04:05:53] <alex4nder> because I'm a badass.
[04:06:10] <ReadError> well shucks
[04:06:31] <ReadError> i took apart my wii nunchuck already tonight!
[04:06:39] <joe9> pfred1: where do you set the limits? the stepconf did not ask me about it.
[04:06:54] <pfred1> joe9 it is on each axis page
[04:07:06] <pfred1> along with your ratio and stuff
[04:07:30] <alex4nder> joe9: why are you going for metric?
[04:07:36] <joe9> pfred1: i followed these instructions http://www.onel.se/all_files/gecko_g540.html
[04:07:39] <joe9> to the letter.
[04:07:46] <pfred1> then you should be good
[04:07:49] <joe9> alex4nder: i prefer metric. easier for me.
[04:07:57] <alex4nder> joe9: your entire machine isn't
[04:08:11] <pfred1> yeah table travel is your limits
[04:08:44] <joe9> alex4nder: is that a big deal?
[04:08:50] <alex4nder> it just makes your life harder

[04:13:04] <joe9> as long as the computer calculates it accurately without error, I am ok with that number.
[04:13:28] <alex4nder> you're a trooper.
[04:13:50] <alex4nder> I had all metric in my garage, but said 'fuck it' when I got a imperial mill and got proper tooling.
[04:13:59] <alex4nder> er an

[04:14:32] <alex4nder> my bikes and cars are all japanese.

[04:19:21] <pfred1> to me a half inch drive sounds better than a thirteen mumblesmeter one
[04:19:51] <alex4nder> yah, and 12mm looks slightly small
[04:20:08] <pfred1> metric hardware is for the birds
[04:20:19] <pfred1> SAE baby
[04:21:28] <pfred1> is electrical stuff in foreign countries metric?
[04:21:38] <pfred1> like the screws in their switches?
[04:22:14] <alex4nder> yah
[04:22:17] <pfred1> I've seen hardware that is standard thread but metric fastener
[04:22:17] <alex4nder> they don't mess around with both
[04:22:34] <alex4nder> well, if the target market is english speaking, weird shit can happen
[04:23:48] <alex4nder> also chryslers
[04:23:54] <pfred1> I have a couple metric taps and dies no complete set though
[04:24:04] <alex4nder> and certain fords
[04:24:15] <alex4nder> I think the american car companies are the worst at that kind of mixed measurement garbage
[04:24:30] <pfred1> I think they're all metric now
[04:24:35] <pfred1> I don't work on new cars
[04:24:54] <alex4nder> yah, I own a mitsubishi and a suzuki, I've got no idea.

[04:28:13] <alex4nder> yah, just make sure you're going up
[04:28:20] <alex4nder> and nothing else is wrong
[04:28:55] <pfred1> there can be some crashing when you're getting started
[04:29:37] <alex4nder> just wait until you do something really dumb, like jam the endmill into the table
[04:29:45] <alex4nder> or forget to turn the spindle on and start your program
[04:30:06] <pfred1> this is why it takes a while to et your limits you want maximum size work envelope but don't want problems

[04:34:54] <joe9> alex4nder: thanks, got it.
[04:36:37] <alex4nder> joe9: cool
[04:37:31] <joe9> so, what are the dumb things to watch out for?
[04:38:34] <pfred1> joe9 get some styrofoam and have at it
[04:39:33] <alex4nder> joe9: you'll find out as you do them
[04:39:40] <alex4nder> unfortunately
[04:40:05] <alex4nder> joe9: also if you plan on doing precision work with PCBs, you need to get proper measurement tools and learn how to use them
[04:40:29] <pfred1> instrumentation is a place to invest
[04:41:17] <joe9> alex4nder: pfred1 what do you recommend?
[04:41:36] <pfred1> I use the 29.99 digital calipers from harbor freight
[04:41:43] <joe9> yes, i have that.
[04:41:43] <pfred1> don't get the silver one get the black one
[04:42:01] <pfred1> the one with auto off
[04:42:12] <pfred1> not that the auto off is the feature that makes it better
[04:42:17] <alex4nder> you'll probably want a dial test indicator, a dial indicator, and various measure of positioning them
[04:42:34] <joe9> yes, that is what i have. pfred1, the black one.
[04:42:45] <pfred1> yeah i have both the silver one is trash
[04:42:57] <joe9> alex4nder: yes, I have the dial indicator from HF with the magnetic base/stand.
[04:43:10] <alex4nder> : |
[04:43:13] <pfred1> the rod one? or the lever one
[04:43:16] <alex4nder> alright.
[04:43:34] <joe9> what is a "dial test indicator"?
[04:43:41] <joe9> i have the dial indicator.
[04:43:45] <pfred1> yeah you know how to indicate work on your table?
[04:44:08] -!- Thetawaves has quit [Quit: This computer has gone to sleep]

[04:44:37] <pfred1> I have both I only use the 1" travel one
[04:44:37] <joe9> I need that. I do not have that.
[04:44:49] <alex4nder> joe9: but you'll want metric
[04:44:50] <joe9> do you mean a "screw gauge"?
[04:44:57] <pfred1> I figure if i get it to 0.001 close enough
[04:45:09] <joe9> let me google up on it.
[04:45:11] <joe9> thanks for the tip.
[04:45:17] <joe9> any other suggestions, please?
[04:45:42] <pfred1> how you hold your work down?

[04:46:07] <pfred1> what?
[04:46:14] <joe9> which is not good. would love something better.
[04:46:21] <pfred1> you need something better than that
[04:46:23] <joe9> oh, you mean the work on the taig.
[04:46:36] <joe9> i bought those T-nuts from a2zcorp
[04:46:37] <pfred1> yes hold downs or a vise
[04:46:49] <joe9> and, they gave a vise with the taig.
[04:46:49] <pfred1> well you need somethng for the t nuts
[04:46:49] <alex4nder> joe9: start by making a fixture to hold PCBs
[04:46:57] <alex4nder> that'll give you something to think about
[04:47:05] <joe9> ok, thanks.
[04:47:11] <alex4nder> because CNC doesn't make it easier to make stuff, it just makes it take less time and skill
[04:47:23] <alex4nder> well s/easier/simpler/
[04:47:34] <alex4nder> the point is, it doesn't make the work go away
[04:47:41] <pfred1> unless you're milling metal yo ucan get away with some pretty shafty setups
[04:48:18] <pfred1> when you try to do metal though you'd better hold that stuff like it is the grip of death
[04:48:33] <alex4nder> yah, unless you like messed up parts and wasted stock
[04:48:43] <pfred1> I've done plenty of setups I thought was rigid enough
[04:48:51] <pfred1> until cutter hit the work
[04:49:07] <pfred1> then I wished I'd done something a bit more substantial
[04:50:00] <pfred1> so the best advise is go through the motions with softer materials
[04:50:09] <pfred1> styrofoam wood stuff like that

[04:53:18] <pfred1> jumping in wiht both feet only to find the pool is draind can though
[04:53:46] <joe9> quick question, What is the default directory for configs that fall under "My configurations"?
[04:53:59] -!- mozmck1 has quit [Quit: Leaving.]
[04:54:57] <joe9> pfred1: my next steps are to 1. get a good dial test indicator., 2. practice on styrofoam and then wood.
[04:55:18] <pfred1> well depends what you plan on doing
[04:55:29] <joe9> pfred1: milling pcb's is my goal.
[04:55:38] <pfred1> if all you want to do is PCBs you could stick a flat into a T slot and put hte board up to it
[04:56:04] <pfred1> you could eyeball it
[04:56:16] <pfred1> as long as the board was oversized to begin with
[04:56:40] <pfred1> which would give you a place to hold it down BTW
[04:56:50] <joe9> makes sense. thanks.
[04:57:02] <pfred1> yeah you don't want ot run into your clamps
[04:57:10] <pfred1> that is very bad
[04:57:22] <pfred1> you could make hold downs
[04:57:43] <pfred1> all you need is a bit of metal with a hole in it
[04:57:47] <joe9> ok, will test it out with a big plywood piece that I have before putting it on an actual pcb.
[04:58:08] <joe9> ok, I can do that too. thanks.
[04:58:21] <pfred1> joe9 http://ecx.images-amazon.com/images/I/31tYHcVtloL._SL500_AA300_.jpg
[04:58:39] <pfred1> that is a hold down probably all you need even flat with a block on the other side would do you
[04:59:14] <joe9> yes, I bought them from a2zcorp.
[04:59:22] <pfred1> http://www.micro-machine-shop.com/clamping_kit.jpg

[05:01:12] <joe9> pfred1: yes, I do.
[05:01:29] <pfred1> you drop that on top of your work with a support block in the back of it and a thread into the pocket to your t nut
[05:01:41] <pfred1> work is held
[05:01:55] <pfred1> sec hold on
[05:02:23] <joe9> that is a good tip. thanks, will check if I can buy something like that (for a smaller size) at HF.

[06:14:59] <pfred1> might have been 93 I forget
[06:15:00] -!- GoSebGo has quit [Quit: Bye]
[06:15:10] <pfred1> we lost the camera in 84
[06:15:15] <Jymmm> I tried for like an hour yesterday to get a flame from an amber, never really happened.
[06:15:18] <pfred1> canoe rolled
[06:15:26] <Jymmm> oooops
[06:15:27] <pfred1> ember
[06:15:32] <pfred1> amber is tree sap
[06:15:33] <Jymmm> ok ember
[06:15:57] <Jymmm> I probably could get a flame from an ember if I had amber sap =)
[06:16:05] <pfred1> the first thing you have to master is always the terminology
[06:16:13] <pfred1> see now the nest time it'll work for you
[06:16:28] <pfred1> you could make a spark with amber
[06:16:31] <Jymmm> Yeah, nest will get me flame too
[06:16:37] <pfred1> but I don't think it'd light any fires
[06:16:46] <Jymmm> you mean ember, right?
[06:16:52] <pfred1> no amber
[06:17:06] <pfred1> it was the first junk they used playing with static
[06:17:18] <Jymmm> yeah, that shit is easy to ignight.
[06:17:24] <Jymmm> ignite
[06:17:32] <pfred1> amber?
[06:17:50] <Jymmm> I want a tinder I can carry that will ignite from an ember.
[06:17:51] <pfred1> amber is actually pertified tree sap it is like a rock
[06:18:25] <pfred1> Jymmm are you one of those doomsday preppers?
[06:18:40] <Jymmm> less the doomsday part.
[06:19:01] <pfred1> the only thing worth preparing is your mind
[06:19:13] <pfred1> forget the rest of the nonsense
[06:19:28] <pfred1> because when it hits the fan there is no telling where any of it will be or you either
[06:19:38] <Jymmm> Yeah, say that when you're freezing your ass off as you have no way to start a fire.
[06:20:06] <pfred1> the best non lighter method is steel wool and a 9 volt battery
[06:20:26] <Jymmm> firesteel works
[06:20:45] <pfred1> just south of where that pic was taken is a whole beach of flint
[06:20:54] <Jymmm> heh
[06:21:04] <Jymmm> you can sell that shit seriously
[06:21:10] <pfred1> we were hanging out on it waiting for the wind to die down on the lake
[06:21:16] <Jymmm> they like that "raw" stuff
[06:21:28] <pfred1> so I grab two rocks start hitting them together guy I was with thought I was crazy
[06:21:39] <pfred1> until a spark came shooting off
[06:21:51] <pfred1> one rock was iron and quartz the other flint
[06:22:11] <pfred1> we were both high out of our minds on acid too
[06:22:18] <pfred1> it was pretty funny
[06:22:19] <Jymmm> lol
[06:22:30] <pfred1> he was lke hooke me up with a pair of those rocks
[06:22:56] <pfred1> it is all in the wrist
[06:24:13] <Jymmm> pfred1: As far as the "prepping" goes, I've seen and had things happen where I need to.
[06:24:42] <Jymmm> Last year the wall heater went out and we have an absent landlord.
[06:24:47] <pfred1> with my luck I'd have a bomb shelter and the bridge would wash out to get to it
[06:25:14] <pfred1> but I'm naturally resourceful so I'm not too worried
[06:25:17] <Jymmm> Luckily it wans't "that" cold that night, but we also have birds.
[06:25:32] <pfred1> heck 2 winters ago I lost electricity for 3 days here
[06:25:38] <pfred1> I use a heat pump for heat
[06:25:45] <pfred1> electric stove
[06:25:45] <Jymmm> and ??
[06:25:55] <pfred1> I had a bag of charcoal
[06:26:07] <pfred1> so I did a lot of barbequeing
[06:26:14] <Jymmm> and for heat?
[06:26:22] <pfred1> I put on my overalls
[06:26:28] <pfred1> it was cold
[06:26:43] <pfred1> house went down to 40
[06:26:58] <Jymmm> Well, I now have an "indoor safe" (subjective) propane heater and 300 hours of propane.
[06:27:17] <pfred1> one of those infared ones?
[06:27:23] <Jymmm> you need to crack the door/window an inch or two
[06:27:25] <Jymmm> no
[06:27:30] <Jymmm> hang on
[06:27:39] <pfred1> I have a couple of block heaters
[06:27:50] <pfred1> I wouldn't call them indoor safe though
[06:28:12] <Jymmm> pfred1: This http://www.mrheater.com/product.aspx?catid=41&id=24

[06:28:33] <pfred1> http://i.imgur.com/9v3PD.jpg
[06:28:39] <Jymmm> pfred1: and this to connect to a 20# tank http://www.northerntool.com/shop/tools/product_200362084_200362084
[06:28:41] <pfred1> it'd blow that whole tent up
[06:28:53] <pfred1> like a balloon
[06:29:16] <Jymmm> well, these ARE indoor safe without venting
[06:29:19] <pfred1> yeah that is in infared
[06:29:39] <Jymmm> it's ceramic
[06:30:33] <Jymmm> It works damn well
[06:30:34] <pfred1> it only flames when it starts then it catalyzes the fuel
[06:30:44] <pfred1> once it heats up
[06:31:02] <Jymmm> I can still see blue flame, just not much
[06:31:09] <Jymmm> it's on behind me right now
[06:32:49] <Jymmm> anyhow the point being is I have emergency portable heat now. It was one of the most difficult things for me to overcome.
[06:33:00] <pfred1> being cold?
[06:33:11] <Jymmm> as we have bird with sensative respritory systems
[06:33:15] <Jymmm> birds
[06:33:27] <Jymmm> coalmines + canaries
[06:33:37] <Jymmm> == gas detection
[06:34:21] <Jymmm> and I can use 1# disposable tanks too
[06:34:36] <pfred1> we tried to blow one of them up once
[06:34:46] <pfred1> taped a half a stick of dynamite to it
[06:34:54] <pfred1> it dented the thing just about in half
[06:35:02] <Jymmm> heh
[06:35:10] <pfred1> yeah it didn't blow up though
[06:35:35] <Jymmm> it's liquid is probably why
[06:35:40] <pfred1> I see the 20# tanks blow up in fires
[06:35:53] <Jymmm> larger are to gasify
[06:35:56] <Jymmm> area
[06:36:06] <pfred1> yeah it was under a burning pickup truck
[06:36:14] <pfred1> raised the whole truck up off the ground
[06:36:29] <pfred1> good few feet
[06:36:44] <pfred1> trick there is you have to plan
[06:37:06] <Jymmm> I have a honda EU2000i too, but to produce electric heat is wasteful
[06:37:08] <pfred1> you have to put the truck on something you can lever it up on while it is on fire so you can get the tank under it
[06:38:14] <Jymmm> Yeah, I just like the lights (pyrotechnics) not blowing shit up
[06:38:37] <pfred1> one bunch of people at that event would bring VW engine blocks
[06:38:47] <Jymmm> magnesium!!1
[06:38:55] <pfred1> they'd get a bed of coals like a foot thick then chuck one of them on it
[06:38:59] <pfred1> yeah
[06:39:05] <pfred1> man it was like a spaceship landing

[06:39:22] <pfred1> yup
[06:39:40] <pfred1> they were pretty crazy
[06:40:10] <Jymmm> Yeah, like I said, I like lights, not blowing stuff up, but I'm aware of all the things out there, they kinda go hand in hand sorta.

[06:40:48] <pfred1> http://www.unadillamx.com/
[06:41:51] <Jymmm> pfred1: Hey, maybe you have an idea....
[06:41:53] <Jymmm> http://i124.photobucket.com/albums/p40/bdwoowoo/Blade%20Forum/010-15.jpg
[06:42:02] <Jymmm> http://i124.photobucket.com/albums/p40/bdwoowoo/Blade%20Forum/007-24.jpg
[06:42:10] <Jymmm> see the green handle on the lid?
[06:42:18] <pfred1> yes
[06:42:27] <Jymmm> It's plastic so you can grab the lid without burning yourself
[06:42:45] <Jymmm> It stays upright on it's own as there is a notch
[06:42:46] <pfred1> only if you like molten plastic on you
[06:43:10] <Jymmm> Right, so what do you suggest to replace it with so that it will STILL stay upright
[06:43:13] <Jymmm> ?
[06:43:34] <Jymmm> http://i124.photobucket.com/albums/p40/bdwoowoo/Blade%20Forum/003-28.jpg
[06:43:48] <pfred1> if it was me I'd say skip the plastic I'd replace it with heavy wire bent so it worked and just use a stick to lift it
[06:44:12] <pfred1> sort of like a tool box latch
[06:44:15] <Jymmm> No, I WANT the tab to stay upright, using a tool is a PITA
[06:44:27] <Jymmm> I like it, it works good.
[06:44:30] <pfred1> well if you form the wire well it would still get hot
[06:44:48] <Jymmm> right, so not metal
[06:45:04] <Jymmm> but somethign tht doens't melt either
[06:45:05] <pfred1> just use a stick
[06:45:08] <Jymmm> no
[06:45:12] <Jymmm> I dont' that,
[06:45:18] <pfred1> OK then how about ceramic?
[06:45:27] <Jymmm> I could do that all day long, that's not what I'm asking about
[06:45:33] <Jymmm> crack?
[06:45:40] <Jymmm> I'm thinking bamboo
[06:45:45] <pfred1> form it around metal wire
[06:46:09] <pfred1> so the ceramic insulator was just on top
[06:46:13] <Jymmm> It has to lay flat so you can close it all up http://i124.photobucket.com/albums/p40/bdwoowoo/Blade%20Forum/001-29.jpg
[06:47:04] <Jymmm> The issue ins't as much the material, is being able to make it stand up.
[06:47:40] <Jymmm> There is a dedicated notch in the handle to make it stay upright
[06:47:45] <pfred1> form the wire with offsets so it had some spring lock action
[06:48:19] <pfred1> it'd have to be the correct gauge wire too not bell wire
[06:48:31] <pfred1> maybe 10 gauge i don't know you'd need to measure it
[06:48:43] <pfred1> whatever the other handle wire is
[06:48:44] <Jymmm> 10ga ?! that's huge
[06:48:53] <pfred1> yeah like the wire of the other handles
[06:49:05] <pfred1> loks about 10 gauge to me
[06:49:16] <pfred1> heavier than 12
[06:49:18] <Jymmm> no no I'm thinking more like 18ga maybe
[06:49:28] <Jymmm> it's just a lide
[06:49:31] <Jymmm> lid
[06:49:49] <pfred1> but it has to fit that loop
[06:49:58] <pfred1> you can make up for it I'll draw a picture
[06:50:55] <Jymmm> I'm thinking like a clothes pin spring where both ends of the wire meet in the loop
[06:51:21] <Jymmm> they spread apart, making the wood stay up, but will spring together to lay flat
[06:52:13] <Jymmm> Kinda like a wire gate on a carabiner works
[06:53:04] <Jymmm> http://www.backcountry.com/images/items/large/MAM/MAM0080/WIGABZ.jpg
[06:53:29] <Jymmm> the holes are offset where the wire fits into
[06:54:28] <pfred1> do it neater but something like this http://i.imgur.com/5VPco.jpg
[06:55:52] <Jymmm> I'm thinking more like this, less the srping part http://3.bp.blogspot.com/-oHLjfKo9TU8/Tjr00uvI5jI/AAAAAAAAAR0/sQWxiDt1CC8/s400/Clothespin4.JPG
[06:56:09] <pfred1> maybe
[06:56:16] <Jymmm> where the spring part is, replace with wood/bamboo
[06:56:34] <pfred1> the spring alone might do the trick
[06:57:04] <Jymmm> maybe, not sure about heat though
[06:58:02] <pfred1> well I'm off to go sleep on it some late here

[10:46:39] <jthornton> you mean G41/42?
[10:48:21] <Loetmichel> *google*
[10:48:24] <Loetmichel> i think so
[10:49:18] <Loetmichel> *grrr, linuxcnc/docs is not responding :-(
[10:50:55] <Loetmichel> can anyone gice me advice how to slightly enlarge (about 3/100mm) a circle made from lines with G41/G42?
[10:52:24] <jthornton> are you already using G41/42?

[10:57:17] <Loetmichel> jthornton: no, i am not, never used, i compensate in the CAM beforehand.
[10:57:32] <Loetmichel> ah, linuxcnc back online, thanks

[10:59:55] <Loetmichel> so: if i write a "G41.1 D0.03" before the circle and a G40 afterwards i should get the desired effect?
[11:00:23] <Loetmichel> (assuming i am milling counter-clocwise inside the bearing seat)
[11:01:46] <jthornton> don't forget you need a move at least as large as the diameter of the cutter as a lead in move
[11:02:01] <Loetmichel> oh
[11:02:09] <Loetmichel> shi*
[11:02:31] <Loetmichel> the moves are VERY tiny 'cause the circkle is made of short lines
[11:03:02] <Loetmichel> ok, the outside is nearly done, i will try in a few minutes.
[11:03:31] <Loetmichel> if you hear something going "CLONK" over hrere something has gone wrong ;-)
[11:04:26] <Loetmichel> ahem: the moves have to be longer than den VIRTUAL diamater, not the actual, right?
[11:05:09] <jthornton> longer than the D yes
[11:05:27] <jthornton> must have enough length to move to the compensated position
[11:06:27] <Loetmichel> i.e: if i misuse the compensation to slightly enlarge the bearing seat it should work?
[11:06:56] <Loetmichel> can linuxcnc handle that small numbers for tool compensation=?

[12:31:28] <joe9> i do not have 12mm wide T slots.
[12:32:38] <joe9> or, maybe i do.
[12:32:38] <jthornton> there is your sign then
[12:32:59] <joe9> just measured the taig table and the bottom wide is around 12mm and the top narrow portion is around 6 mm.
[12:33:05] <joe9> does that make sense?
[12:33:47] <jthornton> I don't know if it makes sense or not I've never owned a mini mill
[12:33:48] <jdhnc> is it 12/6, or 0.5"/0.25"
[12:34:13] <joe9> the 58 piece seems to contain everything that the 42 piece has.
[12:36:02] <jthornton> http://littlemachineshop.com/products/product_view.php?view=classic&ProductID=2718
[12:36:23] <jdhnc> the 58 has 3/8" studs
[12:36:32] <jthornton> the 58 piece set is bigger than your mill

[12:43:54] <joe9> do you think that will be good enough for my clamping needs to hold down a pcb?
[12:43:59] <joe9> or, would I need more?
[12:44:42] <jthornton> for pcb you just need double sided tape as I understand it
[12:45:34] <joe9> jthornton: ok, thanks. I was thinking of clamping it down instead of taping it. but, if that is the only option, then that is what I will go for.
[12:45:35] * jthornton wanders out to the shop
[12:45:59] <jthornton> well you could make a vacuum table...
[12:46:39] <joe9> jthornton: that is out of my league, at this point.
[12:46:49] <joe9> and with drill holes that will not fly.
[12:47:05] <jthornton> of course the best advice will come from someone that has ACTUALLY done a pcb so that's not me

[18:45:20] <pfred1> Thadius type locate linuxcnc
[18:45:33] <Thadius> ok
[18:45:37] <pfred1> well maybe locate linuxcnc | grep config
[18:45:58] <pfred1> the first one might be a little scrolly
[18:46:05] <Thadius> in terminal?
[18:46:09] <pfred1> yes
[18:46:10] <Thadius> sorry, new to linux as well
[18:46:13] <Thadius> ok
[18:46:51] * pfred1 hopes Thadius's db is updated ...
[18:47:03] <pfred1> sudo updatedb
[18:47:20] <pfred1> refreshes slocate
[18:47:57] <pfred1> Linux keeps making me feel like I'm new to it
[18:48:05] <Thadius> i have not updated anything
[18:48:21] <Thadius> linux box isnt connected to interent currently
[18:48:22] <pfred1> yeah run sudo updatedb then run the locate command
[18:48:29] <pfred1> it is a local thing
[18:48:34] <Thadius> ok
[18:48:39] <cradek> you're mistaken about the spelling of "etc"
[18:48:47] <pfred1> that would do it

[18:51:47] <pfred1> time for some brute force searching find / -name "*.ini" | grep linux
[18:52:33] <pfred1> Thadius what version of linuxcnc did yo usay you had?
[18:53:43] <Thadius> i actually do not know my version, i downloaded the 10.04 linuxcnc iso and installed from disk
[18:53:53] <jdhnc> with glxgears, firefox, some other stuff, hwinfo spked it to 12.9k
[18:54:08] <pfred1> jdhnc really good
[18:54:11] <joe9> pfred1: check out the tracing of the linux kernel.
[18:54:24] <joe9> it is pretty helpful to find out what caused the latency.
[18:54:52] <pfred1> the video on this page can give me latency http://www.cyrom.org/palbum/main.php?g2_itemId=4384
[18:54:54] <jdhnc> pfred1: I guess, doesn't matter so much since I have a Mesa card doing stepgens
[18:56:33] <pfred1> jdhnc my P3 does 18400 do this box isn't much better than that
[18:57:38] <Thadius> ok, found it, ver 2.5 linuxcnc
[18:58:34] <pfred1> jdhnc I wanted to make sure you weren't running an older emc2 one
[18:58:50] <Thadius> gotya
[18:59:03] <pfred1> that would change the directory names if you were

[19:01:36] <pfred1> yeah the system can't find it if it doesn't exist yet
[19:01:51] <pfred1> Jymmm carbon?
[19:01:56] <Thadius> sound logic 0_o lol
[19:02:07] <Jymmm> pfred1: thermal non-conductive?
[19:02:16] <pfred1> Thadius run stepconf it'll generate config files for you
[19:02:26] <pfred1> Jymmm carbon doesn't conduct heat very well
[19:02:35] <Jymmm> Really?
[19:02:41] <Thadius> Linuxcnc Stepconf Wizard?
[19:02:48] <pfred1> Thadius yes
[19:03:06] <pfred1> then you'll be able to find them
[19:03:13] <pfred1> make them an easy to find name
[19:03:26] <Thadius> i have a file named v90.stepconf, is that relevant to starting off?

[19:09:09] <ReadError> Thadius: i was looking at one
[19:09:14] <ReadError> you ordered it already?
[19:09:21] <Thadius> i'm making sure i can design, produce gcode, and get linuxcnc up and running before my purchase
[19:09:30] <ReadError> i like the comet, but dont want all the jibbajabba that comes with it like PC
[19:09:34] <ReadError> monitor
[19:09:38] <ReadError> already have enough of that stuff
[19:09:43] <pfred1> Thadius what are you planning on making?
[19:10:30] <ReadError> is it capable of cutting aluminum if you go slow you think?
[19:10:43] <Thadius> plastic case for project flashlight designed with wind-turbine technicians in mind
[19:11:08] <pfred1> then you're going to need CAD software for that
[19:11:26] <ReadError> i thought gcode makes itself?
[19:11:33] <Thadius> i have my CAD/CAM solutions, designed and produced gcode
[19:11:34] <pfred1> not really
[19:11:36] <ReadError> when you convert the cad to it

[19:13:29] <alex4nder> CAM is harder.
[19:13:36] <Thadius> ok, question time
[19:13:37] <pfred1> cad is but at least you can kind of do it
[19:13:46] <ReadError> alex4nder: eagle is pretty simple
[19:13:50] <ReadError> ive done it in the past
[19:13:54] <ReadError> only toner transfers
[19:14:04] <alex4nder> ReadError: easy CAM is easy
[19:14:07] <Thadius> HALui, any advantages adding when running Stepconfig?
[19:14:13] <alex4nder> just whack into the material in a grid
[19:14:14] <alex4nder> done
[19:14:21] <pfred1> I think there is a translator for blender

[19:28:24] <pfred1> don't search for filetype:torrent "machinery handbook" unless you're into really kinky stuff ...
[19:28:25] <ReadError> I got the actual book
[19:28:32] <ReadError> they have a PC version
[19:28:38] <ReadError> that does the calculations and such
[19:29:35] <pfred1> isn't there a script that does some calculating in linuxcnc?
[19:31:20] <Thadius> guys, thanks for your help, looks like i got the stepconfig done for v90
[19:31:33] <pfred1> Thadius now you have a file to find
[19:32:22] <Thadius> ya, working on that part :)
[19:32:46] <pfred1> where the heck are the extra scrips in the install CD?
[19:33:40] <pfred1> oh they're right in /usr/bin
[19:34:55] <Thadius> ok, seems when i modified the v90stepconfig file, it created my v90 folder and everything in the place i was initially looking for
[19:35:07] <pfred1> Thadius the next time you're in Linux in a console for laughs hit tab twice at a command prompt and hit Y
[19:35:40] <Thadius> i'll save that for the next computer i build with ubuntu :P
[19:35:43] <Thadius> :)
[19:36:01] <pfred1> it just did it it doesn't hurt naything
[19:36:10] <pfred1> Display all 2643 possibilities? (y or n)
[19:36:14] <Thadius> i'm confused enough as is
[19:36:18] <Thadius> lol
[19:36:25] <pfred1> those are all the executables on your path
[19:36:49] <pfred1> it is the tab completion hack in the shell
[19:37:12] <Thadius> ok, so in the .zip i downloaded from probotix, they had a v90 folder and a v90stepconfig file.....it looks like after i ran the v90stepconfig file, it created everything that was already in the v90 folder on the zip..
[19:37:46] <Thadius> so, stop me if i'm wrong.... the v90 folder was essentially the offspring of running the stepconfig file?
[19:37:55] <pfred1> whoah what is this freaky program? latencyplot
[19:39:07] <pfred1> it needs a help button I've no idea what any of it means

[19:51:59] <Thadius> just a few projects i have gcode for
[19:52:22] <Thadius> didnt know if i actually needed machine connections first or if linuxcnc could simulate
[19:52:27] <micges> Thadius: you have sim configration directory, sleect from them sim_mm.ini and run it
[19:52:55] <micges> there are many simulated machine configs just for things like that

[19:53:52] <Thadius> i just got stepconfig done for the machine i'm getting, thats all so far

[20:08:10] <pfred1> happy even
[20:08:37] * pfred1 is happy today too
[20:08:58] <pfred1> I didn't get my DVI cable like i wanted but I got a few others things besides
[20:09:27] <gene77> does anyone know what the leadscrew pitch on a mini-lathe is?
[20:10:05] <pfred1> can't put an indicator on it and turn it say 10 times?
[20:10:57] <gene77> done that, wear errors are driving me batty.
[20:12:43] <gene77> scale, accrding to my figures ought to be 51200, but between uneven backlash etc, its difficult to confirm
[20:19:47] <pfred1> yeah you have to discount backlash
[20:20:06] <pfred1> I was just doing it on my mill looks like ever crank is a tenth of an inch on it
[20:21:06] <pfred1> there was someone here that used to talk about how they error mapped their lead screws but I've no idea how they did it
[20:22:21] <pfred1> I want one! http://www.youtube.com/watch?v=mxxdq6y8z8M
[20:27:20] <mrsun> what a beast =)
[20:27:40] <pfred1> mrsun it reminds me of the T-1 from T-2?
[20:29:08] <kb8wmc> is anyone running the Temperature Control Circuit developed by Anders Wallin to run under LinuxCNC? http://www.anderswallin.net/2010/11/temperature-control-circuits/
[20:29:10] <pfred1> gene77 it looks like the developer's handbook covers compensation and error correction
[20:30:59] <gene77> I have read that a couple-4 times. But I think if I want sub 10 thou accuracy on Z, its going to take a ball screw.
[20:32:28] <pfred1> gene77 what kind of machine do you have?
[20:32:44] <gene77> Right now, 10 taps at .1 each are about .001 short of an inch. Unforch there is not only backlash, there is some rubber between the screw and the carriage that I've not ID'd the src of. Yet..
[20:33:21] <gene77> A Speedway branded mini-lathe, very poorly finished IMO.
[20:34:12] <pfred1> for that kind of accuracy you might want to look into a cylindrical grinder or something
[20:35:16] <djdelorie> step config all changed, max speeds now X=180 Y=560 Z=60 IPM, but still under 0.5 thou resolution
[20:35:18] <gene77> I did have the motor laying on the table, doing 50 IPM, but hooked up here, and the driver ratio set to 8 from the 16 it was, I am still getting error stop before I get to 30 ipm.
[20:36:34] <pfred1> djdelorie you got your drivers 0.0005 ?
[20:37:01] <djdelorie> the controller boards have always supported better resolution than that (not physical precision, just steps)
[20:37:16] <djdelorie> but I had the simulated steps/rot too high, linuxcnc couldn't send steps that fast
[20:37:27] <gene77> It runs that lathe-pawn routine pretty well though. I wish stepconfig would run on this box, but it seems it cannot talk to this parport, broken pipe messages galore.
[20:37:40] <djdelorie> so as per advice here, I reduced the steps/rot as much as I could without going about 0.5 thou per step
[20:37:41] <pfred1> djdelorie you realize to get that precision you're up for a 5 digit bill for linears right?
[20:37:56] <djdelorie> pfred: mathematical precision, not physical precision
[20:38:17] <Jymmm> pfred1: Nah, just a lil extra duct tape and oyu can get 10 digit precision
[20:38:25] <pfred1> djdelorie the nI have ot ask what is your target goal
[20:38:27] <gene77> Yup, running at 8 steps, I am going to need a damper, its noisy as hell at about 1.95 ipm
[20:38:41] <djdelorie> there's an upper limit on steps/rot where linuxcnc just can't send steps fast enough, and a lower limit where the motors can't go fast enough to keep up with linuxcnc
[20:39:04] <djdelorie> 0.5 thou is within that range, so I just picked a steps/rot that put me in the 0.1 o 0.5 thou range
[20:39:39] <Jymmm> djdelorie: mid-band compensation is typical built into most (quality) stepper drivers.
[20:39:53] <djdelorie> Jymm: not a stepper driver
[20:39:54] <Jymmm> Geckos, OEM750's, etc
[20:39:55] <pfred1> yeah resonance is a big issue
[20:40:06] <pfred1> bldc don't resonate?
[20:40:06] <gene77> I've done that on my mill too, these acme's aren't micrometer material :)
[20:40:22] <djdelorie> it's a servo motor, yes it resonates, that took a while to dampen as much as I could without losing accuracy
[20:40:30] <Jymmm> djdelorie: ah
[20:40:42] <pfred1> well there are physical dampers too and they will run different under load
[20:41:03] <pfred1> sorts like apple run different :)
[20:41:14] <djdelorie> so anyway, linuxcnc can now command the motors right up to their max RPM
[20:41:24] <pfred1> sounds like progress
[20:41:27] <djdelorie> max Y jog is scary, the whole machine shakes back and forth
[20:41:39] <pfred1> djdelorie I got my dual core to latency test
[20:41:48] <pfred1> djdelorie heh
[20:41:48] <djdelorie> now I just need to single-step this video of the drill test to see if the bit is vibrating...
[20:42:12] <pfred1> yeah your motor setup is pretty powerful
[20:43:27] <pfred1> djdelorie you ever checked out the shopbot style machines?
[20:43:43] <djdelorie> I've looked at way too many machines...
[20:44:22] <djdelorie> yeah, looks like the carriage is shaking when the drill "hits", need to put in a controlled jog
[20:45:12] <djdelorie> axis is still putting a weird symbol way off in space for my drill test job, nothing I've done has made it go away. Instead of a 0.6" square "work area", it's 30.6 by 27.6
[20:46:06] <djdelorie> or a dwell time?
[20:46:25] <pfred1> linuxcnc has accelerate and decellerate
[20:46:40] <pfred1> I mean you got to take inertia into account
[20:47:16] <djdelorie> maybe I need to crank the acc/dec settings way down instead?
[20:47:27] <pfred1> can't hurt to try
[20:47:33] <djdelorie> my motors can acc/dec WAY faster than my plywood table can accomodate :-)
[20:47:43] <pfred1> yes so yo uneed to compensate
[20:47:44] <djdelorie> dwell is in PICOSECONDS? wow.
[20:48:05] <pfred1> linuxcnc means business

[21:34:36] <alex4nder> just don't do it
[21:34:37] <joe9> but, I am thinking about having them.
[21:34:49] <joe9> yesterday, i went too far off my z
[21:34:58] <alex4nder> yah, I remember
[21:35:07] <joe9> and I had to push it up to get the taig z-axis to work.
[21:35:38] <joe9> today, a few times, I was at the end of the axis, and the axis wouldn't turn but make a noise as if it was bumping against something.
[21:35:56] <joe9> http://ganoksin.com/blog/aule/2009/08/11/home-is-where-the-taig-is/
[21:35:59] <alex4nder> did it sound like wurrerrrerrrerrrerrr
[21:36:03] <joe9> yes.
[21:36:07] <alex4nder> your stepper stalled
[21:36:11] <joe9> yes.
[21:36:16] <joe9> i think the stepper stalled.
[21:36:37] <joe9> not sure if doing that many times is a bad idea or if the steppers are designed for it.
[21:36:45] <alex4nder> they're not supposed to do that
[21:36:57] <alex4nder> where was the table/spindle when it stalled?
[21:37:43] <joe9> at the end of the axis. i do not rememeber if the stepper stalled or if it was trying to move but as the axis was at the end, could not move further.
[21:38:03] <joe9> it was like bumping against something.
[21:38:09] <alex4nder> it probably was
[21:38:32] <alex4nder> which axis was it?
[21:38:35] <joe9> when something like that happens, it probably affects the lead screws.
[21:38:43] <joe9> alex4nder: i did that on all 3 axis.
[21:38:47] <joe9> x,y and z.
[21:38:56] <joe9> on Z, when you are all the way at the top
[21:39:01] <joe9> and it cannot go any further.
[21:39:05] <joe9> you get that noise.
[21:39:33] <joe9> on, X-axis, you go all the way to the other direction from where the stepper is
[21:39:43] <joe9> alex4nder: does that make sense?

[21:39:50] <alex4nder> joe9: yah, I don't understand what the problem is
[21:40:01] <alex4nder> it's like if you were asking me why you stall your car when you drive it against a wall
[21:40:13] <alex4nder> it's pretty clear right. ;D
[21:40:30] <joe9> alex4nder: no, I understand why it stops. I want to know how bad it is for the machinery when that happens.
[21:40:40] <alex4nder> the stronger the stepper the worse it is
[21:40:42] <joe9> Would I have messed up something pretty bad.
[21:40:44] <alex4nder> no
[21:40:45] <alex4nder> you're fine
[21:40:56] <joe9> oh, ok. thanks, that is what I was looking for.
[21:41:38] <alex4nder> when you get your measuring gear, you can obsess over backlash
[21:41:51] <joe9> I want to set up the limits of my taig to the actual values instead of the 1000 to -1000 that I have. For the taig, X is 12", y=5.5", Z =6inches.
[21:42:16] <joe9> does that go to MIN_LIMIT and MAX_LIMIT of the AXIS_x of the _.ini file?
[21:42:41] <jdhnc> easier to just set it in stepconf
[21:43:11] <cradek> joe9: yes
[21:43:38] <cradek> joe9: first consider where you will home it. normally Z homes at the top of travel, so MAX is 0 and MIN will be -6
[21:44:02] <joe9> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?MillSetup is what I am trying to do.
[21:44:03] <cradek> this is because you want to be able to home, no matter what's attached to the table.
[21:44:30] <cradek> for XY, home can be wherever. if you have no switches, mark it with a sharpie or something.
[21:44:51] <joe9> the article has it at 0,0,-7.8 in his case.
[21:45:15] <joe9> mine will be 0,0,-6 inches for the MIN_LIMIT for X,Y and Z respectively.
[21:45:31] <cradek> sounds fine
[21:45:49] <joe9> cradek, thanks.
[21:45:57] <cradek> so you'll move X,Y to their low limits to home them
[21:46:10] <joe9> yes.
[21:46:32] <joe9> but, I want to add home switches as here http://ganoksin.com/blog/aule/2009/08/11/home-is-where-the-taig-is/
[21:47:07] <joe9> i think it is good to have home switches, so that I will not get lost while tool changing, etc.
[21:48:12] <joe9> that is the first thing I want to add to my taig. I already have limit switches, but, I am not using them. I should start using them, by positioning them properly.
[21:48:31] <cradek> you can home to limit switches. you don't need more switches if you have the limits.
[21:51:44] <joe9> ok, cool. I will position the limit switches and they will work as home switches too.
[21:52:27] <joe9> cradek: i think it is a good idea
[21:52:51] <joe9> to learn the details/attributes of the .ini file instead of relying on the stepconf.
[21:53:08] <joe9> cradek: do you think it is? or, is it not worth it?

[21:58:20] <joe9> what is the units of the MIN_LIMIT or MAX_LIMIT values? the LINEAR_UNITS = mm and SCALE = 400.0
[21:59:03] <joe9> is it just plain "mm"?
[21:59:52] <joe9> but, that might not make sense as I can seem to move the X-axis more than the 12 inches (as noted in the Specification)

[22:28:24] <alex4nder> joe9: from my experience so far, homing and limits have been the least of my worries.
[22:28:57] <joe9> how do you home it to an exact spot for changing tool bits?
[22:29:12] <joe9> at the exact spot, isn't that hard?

[22:29:15] <alex4nder> homing doesn't help you with changing bits
[22:29:25] <alex4nder> you need a touch off for that.
[22:29:57] <alex4nder> homing gets your machine in sync with the software for X Y and Z
[22:30:02] <alex4nder> but that's spindle Z, not tool Z
[22:32:01] <alex4nder> the "hard" part is touching off on your work.

[22:33:18] <ReadError> and no love on usenet ;(
[22:34:13] <joe9> alex4nder: "touching off" on the work seems a lot harder process than setting up the switches.
[22:35:02] <alex4nder> the switches don't make touching off easier
[22:35:20] <alex4nder> unless your machine loses track of where it is, becasue your steppers stalled.
[22:35:31] <alex4nder> which shouldn't be happening.

[23:49:13] <JT-Shop> joe9, you still have to touch off on the work piece even if you have home switches
[23:52:01] <asdfasd> is there somewhere example how to add touch off button but only for Z axis?
[23:52:38] <JT-Shop> instead of selecting the Z axis and using the normal touch off button?
[23:53:17] <asdfasd> yes, the selected axis is the last I move, and I keep zeroing wrong axis
[23:53:48] <JT-Shop> do you have halui loaded and what version are you running?
[23:54:24] <asdfasd> Im new, I just have fresh instalation, the latest version
[23:54:32] <JT-Shop> which version?
[23:54:49] <asdfasd> 2.4.7
[23:54:58] <jdhnc> almost latest
[23:55:01] <JT-Shop> ok, that is not the latest version
[23:55:16] <jdhnc> touch off with Z-end
[23:55:32] <JT-Shop> do you know where the Show Hal Configuration is on the Axis menu?
[23:55:55] <asdfasd> wow, there is a new version I just noticed it

[23:56:15] <asdfasd> yes I know it
[23:56:24] <jdhnc> 2.5 fixes that oddity with my atom p-port
[23:56:37] <JT-Shop> open up show hal and in the pins see if halui is loaded
[23:57:58] <JT-Shop> and you may not need that...
