[00:15:14] <dad> dad is now known as jlmjvm
[00:18:48] <robin_sz> meep?
[00:19:46] <jmkasunich> beew
[00:21:16] <robin_sz> are you well?
[00:21:26] <jmkasunich> yeah
[00:21:30] <robin_sz> kewl
[00:22:05] <robin_sz> spent the evening fscking about with this poxy wireless router
[00:22:12] <robin_sz> how I HATE THEM
[00:22:20] <jmkasunich> get wires and be done with it
[00:22:29] <robin_sz> I like wireless ...
[00:22:52] <robin_sz> but the poxy desingers need taking out and giving a good kicking
[00:23:28] <robin_sz> all i want it to do is?
[00:23:34] <jlmjvm> whats it doing
[00:23:45] <robin_sz> jlmjvm, annoying me
[00:23:58] <robin_sz> all I need it to do is:
[00:24:15] <robin_sz> connectot wireless devices as 192.168.2.x ,.,,
[00:24:35] <robin_sz> send those packets out onto my wired 192.168.1.x network
[00:24:49] <robin_sz> how hard is that?
[00:24:58] <robin_sz> I do not need it to:
[00:25:04] <jmkasunich> the wired net is administered by another router?
[00:25:10] <robin_sz> yeah
[00:25:24] <robin_sz> thi thing has a bazillion useless options
[00:25:32] <robin_sz> mac address filtereing,
[00:25:39] <robin_sz> access policies
[00:25:43] <jlmjvm> think they need to be on the same network
[00:25:55] <robin_sz> jlmjvm, thanks for trying
[00:26:10] <jlmjvm> mac filtering can be useful
[00:26:10] <jmkasunich> so what is it doing? assigning IPs on the .1 net?
[00:27:00] <robin_sz> jmkasunich, it will work perfectly for a month or two and then go completely arsewit ... I have to factory reset it, plug in to the wired ports I dotn normally use on it, dhcp .. load congig, blah
[00:27:11] <robin_sz> nah, it just periodically craps itself
[00:27:28] <jmkasunich> oh
[00:27:29] <robin_sz> I would have preffered they left off all that crap and just workend on making it stable
[00:29:03] <robin_sz> my original one was a Lucent gateway .. it just sat on the ethernet and had a pcmcia card in it and "did its thing" .. simple bridge between the two nets
[00:29:18] <robin_sz> which was fantastic until it got rained
[00:29:20] <robin_sz> on
[00:35:03] <robin_sz> anyway .. thats cheered me up
[00:35:18] <jmkasunich> what has? beer?
[00:37:28] <robin_sz> no .. what just whining about the wireless thing ... got it off my chest
[00:37:34] <jmkasunich> ah
[00:37:40] <jmkasunich> sometimes that works quite well
[00:37:48] <robin_sz> saved me takingit into the back hard and flattening it with a brick anyway
[01:25:11] <K`zan> http://wrlabs.shacknet.nu/~vw/MyMachineShop/tmp/WoodToolRest/
[01:25:12] <K`zan> :-)
[02:16:42] <jtr> robin_sz: I'm using a d-link wireless router as an access point only - just turned off DHCP and plugged the LAN side into the local network.
[02:17:08] <jtr> robin_sz: the WAN side is swinging in the wind
[03:53:08] <jmkasunich> matt!

[06:35:55] <Jymmmm> * Jymmmm drops a pin... KaBOOOOOOOOOOOOOOOOOOOOOOOOOM!
[06:38:33] <ds3> hey use a non sparking pin!!!!!
[06:39:15] <Jymmmm> In was a grenade pin =)
[06:55:21] <ds3> still don't want a gas explosion before it detonates!
[06:58:17] <Jymmmm> it was brass I tell ya, just a VERY fase fuse
[07:06:12] <K`zan> Night folks.
[07:06:40] <Jymmmm> laters
[07:18:15] <cncjunior> hello !
[07:19:22] <Jymmmm> nobody home (I think)
[07:19:31] <a-l-p-h-a> none
[07:20:52] <toastydeath> ALARM: ZERO AXES
[07:20:59] <toastydeath> (nobody home)
[07:21:09] <toastydeath> badum tsh!
[07:21:34] <Jymmmm> lol
[07:21:47] <a-l-p-h-a> too tired to figure that out
[07:22:02] <Jymmmm> a-l-p-h-a read it agian, took me a sec
[07:22:02] <a-l-p-h-a> raptors vs rockets... raptors got torn to shreds.
[07:22:16] <a-l-p-h-a> oh
[07:22:19] <a-l-p-h-a> I get it now.
[07:22:20] <a-l-p-h-a> h

[07:27:50] <Jymmmm> hasta
[07:34:48] <cncjunior> i work on hal and try motion.adaptive-feed but i get the message pin does not exist
[07:35:04] <cncjunior> what is wrong ?
[09:31:57] <cncjunior> hello !
[10:48:27] <cncjunior> hi !
[14:31:53] <steves_logging> steves_logging is now known as steve_stallings
[14:32:39] <cncjunior> hi !
[14:34:38] <rayh> hi
[14:45:11] <DanielFalck> cncjunior: is your nickname related to the machine that you are using? I remember a company called 'cncjunior' a long time ago
[14:45:57] <cncjunior> DanielFalck: no, my name is rerlated with my cnc knowledge
[14:46:07] <DanielFalck> ok
[14:46:40] <DanielFalck> I had a friend who had a 'cncjunior' mill/drill. I changed out the control for him
[14:47:30] <cncjunior> i work on an adaptive cnc project . i need all 5 in pins from parport
[14:48:14] <cncjunior> pin 10,11,12 , 13 are ok but emc 2.1.1 can't see pin 15
[14:49:01] <cncjunior> i want to install now a second parport. how ?
[14:52:27] <tomp> easiest way is to plug in pci parallel port, it may give you 2 new parallel ports. then, use 'lspci -v' to find its address(s).
[14:52:36] <tomp> 0000:00:09.0 Parallel controller: Siig Inc CyberParallel (2-port) (prog-if 02 [ECP])
[14:52:43] <tomp> Subsystem: Siig Inc CyberParallel (2-port)
[14:52:57] <tomp> I/O ports at 9400 [size=8]
[14:53:03] <tomp> I/O ports at 9800 [size=4]
[14:53:12] <tomp> I/O ports at 9c00 [size=8]
[14:53:27] <tomp> I/O ports at a000 [size=4]
[14:54:12] <tomp> then in your .hal file add oadrt hal_parport cfg="0x9400" (whatever you got reported by lspci
[14:54:26] <tomp> loadrt hal_parport cfg="0x9400"
[14:54:35] <cncjunior> i have an old PIII at 500 Mhz and an ISA card with parport on it
[14:55:11] <jepler> cncjunior: what do you mean emc "can't see pin 15"? Pin 15 appears in 'halcmd show' on my system, though I don't actually use that input pin in my configuration.
[14:55:11] <tomp> then dmesg should show it ( it should be noticed at boot )
[14:55:16] <jepler> tomp: false
[14:55:19] <tomp> k
[14:55:53] <jepler> tomp: emc forces the kernel parallel port driver not to load, so that no application besides emc can accidentally send data to your mill
[14:56:23] <tomp> jepler: k
[14:57:03] <cncjunior> jepler: i check with led and halmeter pins 10,11,12,13 and 15.
[14:57:29] <cncjunior> pin 15 remains on high state
[14:58:24] <cncjunior> jepler: maybe the parport is not ok, also the c code from source could be wrong.
[14:58:52] <jepler> cncjunior: I doubt the source code is wrong, but that's possible
[14:58:59] <cncjunior> jepler :i will check on another computer
[14:59:54] <cncjunior> jepler : also i want to install a second old ISA parport. how ?
[15:00:10] <jepler> cncjunior: you have to determine the address the port uses, and then use that in your hal_parport cfg= string
[15:00:54] <cncjunior> jepler: ok, i understand, thank you
[15:01:06] <jepler> to have two ports you use 'cfg="addr1 addr2"'
[15:01:23] <jepler> use 0xHHHH for an address in hexadecimal
[15:02:26] <cncjunior> jepler : i will write down all these sintax, also i have all handboks...
[15:04:38] <jepler> cncjunior: the syntax is shown in section 13.1.1 of my copy of the EMC2 Integrator Manual
[15:06:29] <cncjunior> jepler: now i found it.
[15:11:30] <rayh> logger_emc: bookmark
[15:11:31] <rayh> Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2007-03-17.txt
[15:14:43] <cncjunior> \leave
[15:16:54] <jepler> rayh: what is the term for the distance between the rows (or columns, depending how you look at it) in 3D_Chips? Is that the "step over"?
[15:17:13] <tomp> cncjunior: :( this always happens.. he left... the most common way to find the address of isa parallel port cards is: on the card itself. there are jumpers and legends on most isa pport cards ( not all )
[15:17:32] <rayh> I think that's it, jepler
[15:18:45] <jepler> rayh: thought so, thanks
[15:19:00] <tomp> http://eml.ou.edu/siamak/cnc/stepover.asp
[15:19:40] <rayh> you bet. I know a guy who really cut chips but he had to go back to the original and slice it different both ways.
[15:29:04] <CIA-6> 03jepler 07TRUNK * 10emc2/docs/src/gui/ (image-to-gcode.lyx image-to-gcode.png): document image-to-gcode
[15:30:46] <CIA-6> 03jepler 07TRUNK * 10emc2/docs/src/ (Submakefile index.tmpl Master_User.lyx): add image-to-gcode documentation
[15:43:23] <CIA-6> 03jepler 07TRUNK * 10emc2/src/emc/usr_intf/axis/scripts/image-to-gcode.py:
[15:43:23] <CIA-6> fix options to have the names I gave them in the documentation
[15:43:23] <CIA-6> make the plunge feed rate settable in the user interface--it was hard-coded to 6IPM before
[15:59:34] <Jymmmm> On sale for $62.99, worth it? http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=93981

[16:30:25] <Jymmmm> Masn, I swear... I love this shedder my gf got me, but scares the crap out of me! I would NEVER want this ting to ever grab something "accidentally".
[16:30:37] <CIA-6> 03jepler 07TRUNK * 10emc2/docs/src/gui/image-to-gcode.lyx: fix typo. add new plunge feed option
[16:31:09] <Jymmmm> jepler: is image-to-gcode visual? (in axis)
[16:36:22] <jepler> Jymmmm: it's not as interactive as I'd like
[16:36:28] <jepler> Jymmmm: I'm not sure what you mean by "visual"
[16:36:45] <Jymmmm> jepler you can see the results of the output before cutting anything.
[16:37:31] <jepler> Jymmmm: yes, the same preview you get with any g-code
[16:37:35] <Jymmmm> ah, ok
[16:38:19] <jepler> http://linuxcnc.org/docs/devel/html/gui/image-to-gcode/image-to-gcode.png
[16:38:46] <jepler> this shows the image-to-gcode window, and what you see in AXIS after you hit OK
[16:39:01] <jepler> full docs: http://linuxcnc.org/docs/devel/html/gui/image-to-gcode/image-to-gcode.png
[16:39:06] <Jymmmm> cool beans =)
[16:39:21] <jepler> er
[16:39:24] <jepler> full docs: http://linuxcnc.org/docs/devel/html/gui/image-to-gcode/
[16:41:15] <Jymmmm> jepler come a long ways since just your python script =)
[16:43:48] <jepler> Jymmmm: yeah that first script of chris's was a lot simpler
[16:44:04] <Jymmmm> heh
[16:44:51] <unter_e> I get a message ERROR: Unexpected realtime delay: check dmesg for details.
[16:44:57] <unter_e> however, there are no details in dmesg
[16:45:22] <unter_e> oh sorry, there is something I don't understand
[16:47:41] <Jymmmm> Jymmmm is now known as Red70sShow
[16:47:43] <Red70sShow> Red70sShow is now known as Jymmmm
[16:50:59] <unter_e> this hal thing is cool beyond my powers to express it
[16:51:19] <unter_e> I built a fatigue machine using real time linux, and it's so frustrating to get output
[16:51:41] <unter_e> might have to build a fatigue machine controller using hal
[16:53:21] <DanielFalck> unter_e: tell me more about the fatigue machine
[16:53:55] <DanielFalck> unter_e: this link might be of help to you:
[16:53:56] <DanielFalck> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?TroubleShooting#Unexpected_realtime_delay_check_dmesg_for_details
[16:54:44] <unter_e> Dan, thanks
[16:54:55] <unter_e> http://muri.mne.psu.edu/electro_mech/fatigue_apparatus.htm
[16:55:36] <unter_e> I'll have to admit I didn't write that web page, and there could be misinformation there
[16:55:46] <DanielFalck> cool enough though
[16:56:30] <unter_e> the load frame was built for Nasa to do work on the saturn 5 project
[16:56:51] <DanielFalck> on the realtime error- I have the same thing going on with a Compaq presario with onboard video. So, I need to figure it out too.
[16:57:27] <unter_e> I'm running a pIII, I thought those errors didn't start showing up until p4 territory
[16:58:04] <DanielFalck> Mine has an AMD 500 in it
[16:58:21] <unter_e> link says nvidia may cause the problem
[16:58:31] <unter_e> have to check which driver I'm using
[16:58:34] <DanielFalck> ati also
[16:58:42] <unter_e> yeah, but I would never run ati
[16:59:09] <unter_e> mostly joking there
[16:59:18] <DanielFalck> what other video cards are there that would be ok? I don't know much about them.
[16:59:34] <unter_e> I'm trying to think of any
[16:59:39] <unter_e> not many left
[17:00:10] <unter_e> all the little companies are using ati or nvidia chipsets, and somehow I doubt that the offbrand chipsets are well supported
[17:00:40] <unter_e> it's just that the problems show up with nvidia or ati because we all use them
[17:00:49] <unter_e> via still makes video I think
[17:02:54] <unter_e> I'm using nv so that may not be it
[17:03:05] <jepler> unter_e: try switching to "vesa"
[17:03:28] <unter_e> I don't know if running emc over ssh might cause problems, probably shouldn't
[17:04:32] <rayh> I've got via chrome on an 1g mini-itx and don't see any serious delays.
[17:04:48] <Jymmmm> it runs okey, but haven't tested it fully, though it runs very nice when xopen
[17:05:39] <unter_e> seems that it could be my motherboard too though
[17:05:53] <unter_e> I'm using a RIVA TNT card
[17:06:31] <unter_e> to use visa, can I just go through xorg.conf and replace every nv with vesa?
[17:06:39] <jepler> unter_e: there should be just one
[17:07:45] <unter_e> guess I can't count, thought there were a minute ago, but now I just see one
[17:08:51] <rayh> Sure you can hand edit xorg, save a backup in case it won't restart.
[17:08:59] <unter_e> That's what I did
[17:09:33] <unter_e> rebooting it now, one advantage of ssh, I can still bother you guys while I'm rebooting
[17:25:19] <Jymmmm> SWPadnos: http://www.weirdstuff.com/cgi-bin/item/29429
[17:28:31] <jepler> hah "Robot Emercancy Stop"
[17:29:49] <Jymmmm> heh
[17:30:01] <Jymmmm> they have a closeup of the keypad too
[17:30:20] <jepler> darn it's spelled right there
[17:30:44] <Jymmmm> oh didnt catch the misspelling
[17:31:05] <unter_e> you would hope it would be spelled right on the controller
[17:31:10] <Jymmmm> it might be a cool thing to add to emc, but only 12 available.
[17:31:59] <unter_e> I have something very much like that one
[17:54:46] <toastydeath> those little handle doodads are only useful on big mills and lathes
[17:55:04] <toastydeath> ones where you have to sit on the table to touch tools off
[18:01:07] <a-l-p-h-a> say I two 6" pieces of (1/8" x 3/8" copper rect. bar) http://tinyurl.com/3yssaz to make to power rails, a positive and negative. Drill some holes and soldered in parallel three 4700uF 100VDC and a bleed resistor, with tapped holes at both ends for #8 or #10 screws used for quick connects. Is this a dumb idea?
[18:01:46] <jmkasunich> overkill
[18:01:56] <jmkasunich> how many amps do you need?
[18:01:58] <Jymmmm> you're trying to make a buss bar?
[18:02:26] <a-l-p-h-a> pretty much a buss bar. I forgot what they were called. jepler that's the smallest copper size I could find. 5amps, MAX!!! but more like 2.8amp.
[18:02:32] <jmkasunich> 1/8 x 1/8 is probably good for 40 amps
[18:02:57] <a-l-p-h-a> jmkasunich, but I couldn't make scree terms then at the end... hehe.
[18:03:48] <jmkasunich> are you mounting the caps to the bars, or the bars to the caps?
[18:03:49] <Jymmmm> http://www.allelectronics.com/cgi-bin/item/TB-41/755/41_AMP_FEED-THROUGH_TERMINAL_STRIP_.html
[18:04:02] <jmkasunich> (IOW, how are you gonna secure the whole thing?)
[18:04:06] <a-l-p-h-a> jmkasunich, bars to the caps
[18:04:46] <a-l-p-h-a> Jymmmm, nice.
[18:04:58] <jmkasunich> http://www.allelectronics.com/cgi-bin/item/TS-205/755/5-POSITION_DUAL-ROW_STRIP,_20_AMP_.html
[18:05:05] <jmkasunich> even cheaper
[18:05:19] <a-l-p-h-a> hang on.
[18:09:00] <Jymmmm> my dust enclosure is getting way too warm inside (90+F after a 10 minutes job). It's 48 cubic feet, about what CFM would I need to bring in fresh air to keep it cool enough?
[18:09:26] <jmkasunich> how many watts are being dissipated inside?
[18:09:57] <Jymmmm> My 2.25HP router motor collet will burn my fingers
[18:09:58] <jmkasunich> CFM = 1.75 * power / deltaT, where deltaT = degrees C
[18:10:15] <Jymmmm> plus 3 steppers
[18:10:28] <jmkasunich> your router isn't running at a real 2.25HP
[18:10:41] <Jymmmm> hang on
[18:10:59] <toastydeath> either that, or your router has a huge, huge motor
[18:11:11] <jmkasunich> real 2.25HP with a 100% efficient motor would draw 14A at 120V
[18:11:29] <jmkasunich> and routers are far from 100% efficient
[18:12:21] <jmkasunich> Jymmmm: are you doing anything for dust collection? (shop vac or whatever?)
[18:12:20] <Jymmmm> rated at 12a
[18:12:26] <Jymmmm> jmkasunich none
[18:12:44] <toastydeath> you should probably start dust collecting
[18:12:45] <jmkasunich> hmm
[18:12:53] <toastydeath> on a router
[18:13:13] <toastydeath> that's an explosion hazard, along with an inhalation hazard
[18:13:15] <jmkasunich> wood dust, suspended in the air in an enclosed 48 cu ft box, with a router motor that has possibly sparky brushes
[18:13:17] <a-l-p-h-a> is what I am going to use. I was going to drill into the 1/8x3/8 bar, 1/16" holes for each cap lead, and solder the cap to the buss bar. At the each end of each buss bar, drill and tap a #8 or #10 for screw terms.
[18:14:08] <jmkasunich> a-l-p-h-a: whatever floats your boat
[18:14:21] <jmkasunich> that assembly still needs to be fastened down somehow
[18:14:23] <a-l-p-h-a> jmkasunich, okay... so it's overkill, but will work...
[18:14:48] <a-l-p-h-a> jmkasunich, okay... I'll show you how I fastened my other ones...
[18:14:49] <jmkasunich> I'd be more inclined to use a terminal block for external connections, fasten the caps down any old way, and wire with ordinary wire
[18:14:50] <Jymmmm> jmkasunich never considered that aspect - floating dust.
[18:15:00] <Jymmmm> and faston connectors
[18:15:16] <toastydeath> jymmmm: textile factories used to explode from lack of dust collection
[18:15:26] <jmkasunich> Jymmmm: if you can arrange for a shopvac to pull out dust, it will also remove some heat (warm air)
[18:15:55] <toastydeath> also, you can develop some pretty serious respatory issues with the stuff
[18:16:09] <Jymmmm> jmkasunich My shopvac is 2.5" - would that be big enough?
[18:16:19] <jmkasunich> shopvac with the exaust piped out the window maybe, so any dust that escapes the filter won't bug your birds
[18:16:37] <jmkasunich> gotta be better than what you have now
[18:16:40] <Jymmmm> jmkasunich I have a 4 micron filter on the shopvac
[18:16:45] <toastydeath> it might die
[18:16:48] <jmkasunich> I don't know the CFM for a shopvac
[18:16:50] <toastydeath> but it'll work for the time
[18:17:17] <jmkasunich> how many hours a day do you run the router?
[18:17:44] <jmkasunich> if its 1/2 to 2, then shopvac might be ok, especially if its 20 mins on, then off for a while, etc
[18:17:53] <Jymmmm> not much atm, but trying to work out all the bugs right now.

[18:18:00] <toastydeath> http://www.harborfreight.com/cpi/ctaf/Displayitem.taf?itemnumber=45378
[18:18:00] <jmkasunich> if you're running 8 hours a day, the shopvack won't hold up
[18:18:08] <a-l-p-h-a> are how I held down the caps in my other power supply
[18:18:11] <Jymmmm> my shopvac gets warm by itself.
[18:18:12] <toastydeath> dust collector links on harbor freight
[18:18:29] <Jymmmm> I wasn't ready to spend $100 http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=94029
[18:18:39] <Jymmmm> loud lil shits
[18:19:00] <jmkasunich> Jymmmm: bet its quieter than a shopvac
[18:19:08] <toastydeath> well, dust collection in a hobbyist shop is a real serious issue
[18:19:12] <toastydeath> and most people don't understand it
[18:19:18] <Jymmmm> jmkasunich Thanks for remembering =) But I'm in a garage now, the biries are inside =)
[18:19:29] <toastydeath> you want dust collection
[18:19:36] <toastydeath> want/need
[18:19:46] <Jymmmm> jmkasunich Yeah, mine is noisey,
[18:19:58] <jmkasunich> toastydeath: since the machine is enclosed, he technically could get away with exhaust instead of collection
[18:20:07] <jmkasunich> he's not breathing the air in the enclosure
[18:20:14] <toastydeath> good
[18:20:18] <toastydeath> exhaust would be great
[18:20:18] <Jymmmm> till I open the doors =)
[18:20:43] <jmkasunich> Jymmmm: can you scrounge an old furnace blower? or something similar but smaller?
[18:21:09] <Jymmmm> But, my gf commented on the smell from the plastics I've been machinging, I might as well go for the blower and add on a activated charcoal filtering too
[18:21:46] <Jymmmm> Eeeesh, I'm gonna get nickled and dimed to death on this one! LOL
[18:23:04] <Jymmmm> ok, does that mini dust collector look ok?
[18:23:37] <Jymmmm> brb... coffee
[18:24:00] <toastydeath> i have no idea
[18:24:39] <toastydeath> it's harbor freight, it may blow up on the third day
[18:26:57] <plattschnauze> hello together , in case i realy want to learn programming under phyton , wich version do i have to get ??
[18:27:49] <a-l-p-h-a> 2.5 would probably be a good start.
[18:28:13] <a-l-p-h-a> plattschnauze, ##python has lots of gurus
[18:28:26] <plattschnauze> is this in art of for example VB-net ?
[18:28:36] <toastydeath> ..?
[18:28:37] <a-l-p-h-a> "in art"?
[18:28:44] <toastydeath> python has nothing to do with .net
[18:28:58] <a-l-p-h-a> that translator software is not working well.
[18:30:03] <plattschnauze> sorry for that , i mean in style (because i know VB a bit)
[18:30:42] <toastydeath> no
[18:31:24] <toastydeath> the basic concepts are the same, but how you do things in python is different from how you do them in vb
[18:31:56] <toastydeath> and there is stuff in python that you do not have in vb
[18:32:12] <plattschnauze> ok, is there a way for a non programmer to learn it , in case he knows some basics of programms ?
[18:32:26] <toastydeath> look for python tutorials
[18:32:29] <toastydeath> on google
[18:32:50] <plattschnauze> ok , lets start , thanks
[18:33:47] <LawrenceG> http://julius.jornada.com.mx/browser/documents/python/diveintopython-pdf-5.4.zip?rev=49&format=raw is a good python tutorial
[18:35:05] <plattschnauze> in case it fails , is there someone who could write a programm to catch and save teached positions of emc for 6 axis ?
[18:35:31] <toastydeath> ..SIX axis?
[18:35:41] <plattschnauze> roboter !!
[18:35:49] <toastydeath> oh, good point
[18:37:26] <cncjunior> hi !
[18:37:47] <Vq^> hello mr Junior
[18:39:06] <cncjunior> i tested the m52 adaptive feed and it work great.
[18:39:06] <feoc> ello
[18:39:30] <Jymmmm> oh hell... now I gotta see if i have enough juice in the garage... only have a 15a circuit
[18:39:54] <toastydeath> home depot sells 4/0 gauge
[18:39:58] <toastydeath> for like a dollar a foot
[18:40:25] <Jymmmm> not my place, or the garage would have it's own panel
[18:40:43] <toastydeath> i'm saying you could re-run the wire
[18:40:44] <toastydeath> with 4/0
[18:40:52] <toastydeath> then you could power your neighbor's house off your garage circut
[18:40:55] <Jymmmm> agian, not my place.
[18:40:59] <toastydeath> ohhh i get it
[18:41:09] <toastydeath> "not your place" as in you don't own it
[18:41:11] <toastydeath> right-o
[18:41:24] <Jymmmm> yep =) just a rental
[18:41:57] <a-l-p-h-a> Medium size electroclytic caps ( ) ~1.25"dia x 2", does mounting orientation (leads up/down) matter?
[18:42:42] <Jymmmm> Though, I do know where there is a unused 15a circuit (non-existant garbage disposal), just not sure how to wire it from kitchen to garage in crawl space.
[18:45:01] <Jymmmm> Custom prined M&M's... mymms.com/freebag7
[18:45:12] <Jymmmm> promocode: freebag7
[18:45:24] <Jymmmm> printed
[18:49:18] <Jymmmm> jmkasunich: Do you think this will keep the heat done to a reasonable level? http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=94029
[18:49:24] <Jymmmm> s/done/down/
[18:51:24] <jmkasunich> Jymmmm: certainly
[18:51:31] <jmkasunich> 914CFM!
[18:51:53] <jmkasunich> for a 48 cubic foot box that is a hurricane
[18:52:02] <Jymmmm> jmkasunich router + blower + pc + drivers == 15a or less ?
[18:52:14] <jmkasunich> read and add
[18:52:25] <jmkasunich> the dust collector says 6.8A
[18:52:31] <jmkasunich> read the router label
[18:52:34] <Jymmmm> 12a
[18:52:48] <jmkasunich> the PC is maybe 200 watts = a little under 2A
[18:53:07] <Jymmmm> I've never been sure if label rating is peak, or ???
[18:53:21] <jmkasunich> it is usually the full load rating
[18:53:33] <jmkasunich> if the router is running at less than full load it will pull less than 12A
[18:53:38] <a-l-p-h-a> Jymmmm, great way to ask a girl to marry you...
[18:53:56] <jmkasunich> but the total for everything you are talking about is to much for a 15A circuit
[18:53:59] <Jymmmm> so if label rating is 12a, startup could be higher than that?
[18:54:05] <jmkasunich> startup, yes
[18:54:11] <jmkasunich> but thats not a problem, its over fast enough
[18:54:12] <Jymmmm> *sigh*
[18:54:25] <jmkasunich> don't start the router and the dust collector at the same time is all
[18:54:54] <Jymmmm> yeah, delay timer relay if I ever automate it
[18:55:43] <jmkasunich> can't tell from the pic if that dust collector has an induction motor or a universal motor
[18:55:52] <jmkasunich> (universal motors are like those on routers)
[18:56:24] <Jymmmm> it has replacable brushes if that means anything
[18:56:40] <jmkasunich> induction is more reliable and quieter, with no brushes to wear out and slower speed
[18:56:44] <jmkasunich> ok, then its universal
[18:57:05] <jmkasunich> normally that would be a bad thing - brushes wear out, high speed means more noise, etc
[18:57:07] <Jymmmm> lol "easy Access Carbon Brushes"
[18:57:29] <jmkasunich> but in this case it means you could use a speed controller to slow it down
[18:57:36] <jmkasunich> reduce noise and power draw
[18:57:54] <jmkasunich> you don't need 900CFM
[18:58:25] <jmkasunich> if you want to capture floating dust (as opposed to heavy chip and coarse dust) you can use much less air
[18:58:30] <Jymmmm> on sale for $12.49 http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=43060
[18:58:47] <jmkasunich> 200 CFM still means the air in your box gets replaced with fresh every 15 seconds
[18:59:09] <jmkasunich> yeah, like that
[18:59:15] <Jymmmm> okey cool, wasn't sure if speed control would work on this type of motor.
[18:59:15] <jmkasunich> at the sale price, I'd buy two
[18:59:22] <jmkasunich> one for the blower, one for the router
[18:59:35] <jmkasunich> you might find it cuts better at slower speeds anyway
[18:59:41] <Jymmmm> router has speed control on it already 8k to 25k
[18:59:48] <jmkasunich> ok
[19:00:08] <Jymmmm> but, I could use it on the grinder/bench sander
[19:00:22] <jmkasunich> only if it has a universal motor
[19:00:49] <jmkasunich> induction motors are the ones that are rated 1700-1780 RPM, or 3500-3550, etc
[19:00:49] <Jymmmm> ah
[19:01:01] <Jymmmm> http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=93981
[19:01:02] <jmkasunich> and have no brushes
[19:01:15] <jmkasunich> thats induction
[19:01:23] <jmkasunich> 1780 rpm
[19:01:31] <Jymmmm> ah
[19:01:44] <jmkasunich> and you can see the starting cap on the motor (the hump, just above the miter gage on the table)
[19:01:52] <Jymmmm> yeah, saw that
[19:02:01] <jmkasunich> induction motors are better for most stuff - reliable and quiet compared to brush motors
[19:02:15] <Jymmmm> is that sander worht it you think?
[19:02:21] <jmkasunich> I dunno
[19:02:22] <Jymmmm> on sale for $63
[19:02:42] <jmkasunich> I'm a snob, so you shouldn't ask me about HF stuff
[19:02:48] <Jymmmm> I've never used one before, but have the need for it.
[19:03:12] <Jymmmm> tis ok, I know HF is crap, but once in a while to find a gem in the rough.
[19:03:27] <jmkasunich> I have a HF bandsaw, and I've been happy with it
[19:03:37] <Jymmmm> that's one of the gems I speak of
[19:03:46] <jmkasunich> the rest of my tools are a random assorment, mostly used american made
[19:04:10] <unter_e> if you are married, it makes more sense to get high quality
[19:04:12] <Jymmmm> I bought a trim router from HF, it started meliting the casing w/o any load on it.
[19:04:18] <jmkasunich> the problem with used american made is that you can't pick it out of a catalog - you accumulate things over the years as you find them
[19:05:10] <jmkasunich> unter_e: what does marriage have to do with it?
[19:05:27] <unter_e> don't have to explain buying something twice
[19:05:34] <jmkasunich> heh
[19:05:49] <jmkasunich> I'm married to a bench jeweler who has an appreciation for good tools
[19:06:07] <jmkasunich> she has about 20 pairs of different kinds of pliers, including the nice $25 german ones
[19:06:08] <unter_e> I think I speak for all of us when I say that I hate you
[19:06:20] <Jymmmm> what unter_e said
[19:06:20] <jmkasunich> lol
[19:07:00] <plattschnauze> ok , after reading the first pages of totorial my first thought is , i will never learn it! no time for what it needs to understand , back to my question, anyone else, there are some others outside waiting for a way to teach positions
[19:07:02] <Jymmmm> Jymmmm has changed the topic to: Welcome! EMC (Enhanced Machine Controller) is a linux-based CNC control. | Latest release: EMC 2.1.2 | http://www.linuxcnc.org | http://wiki.linuxcnc.org || <unter_e> jmkasunich: I think I speak for all of us when I say that I hate you
[19:07:45] <unter_e> don't think that worked the way it should have
[19:07:59] <jmkasunich> Jymmmm: put it back the way it was
[19:08:13] <Jymmmm> jmkasunich dumbass question.... so the speed control will reduce the power draw from the blower?
[19:08:22] <jmkasunich> yes
[19:08:26] <jmkasunich> (and the noise)
[19:08:29] <Jymmmm> Jymmmm has changed the topic to: Welcome! EMC (Enhanced Machine Controller) is a linux-based CNC control. | Latest release: EMC 2.1.2 | http://www.linuxcnc.org | http://wiki.linuxcnc.org
[19:08:39] <Jymmmm> oh, good to know on the noise.
[19:08:57] <jmkasunich> you should be able to turn it down to about half speed and still have floating dust and heat removed from your box very nicely
[19:09:16] <jmkasunich> make sure you provide some air inlet opening, preferrably opposite the box from the exhaust port
[19:09:38] <jmkasunich> or you might suck your box out of shape
[19:09:54] <unter_e> John, have you worked with your mesa board at all?
[19:09:56] <Jymmmm> On the top of the 4'x4'x 3' tall enclosure, there is a 2' x4' panel only coverd in canvas
[19:10:25] <jmkasunich> unter_e: a little - got distracted working on the stepgen issues that Ed Nisley found
[19:10:27] <a-l-p-h-a> Jymmmm, loose canvas, or dense?
[19:10:28] <jmkasunich> hope to get back to it very soon
[19:10:41] <Jymmmm> the rest of the sides are covered in clear vinyl on top of al screen
[19:10:53] <Jymmmm> a-l-p-h-a painters tarp anvas
[19:10:56] <Jymmmm> a-l-p-h-a painters tarp canvas
[19:11:08] <jmkasunich> not very porous then
[19:11:12] <Jymmmm> 8 sq ft worth
[19:11:13] <a-l-p-h-a> Jymmmm, hmm... yeah, what jmkasunich said.
[19:11:36] <a-l-p-h-a> Jymmmm, think about window screening, 2-3 layers of it.
[19:11:51] <a-l-p-h-a> for a window on the opposite side.
[19:12:12] <jmkasunich> this is an air inlet, so it doesn't have to be particularly "filtery"
[19:12:21] <a-l-p-h-a> pourous, but tiny enough to prevent chips to fly in.
[19:12:55] <Jymmmm> well, if the dbl doors suck closed all by themselves, I know it's too fine =)
[19:12:56] <jmkasunich> the chips are already on the inside ;-)
[19:13:09] <a-l-p-h-a> I saw this at my electronics store today... a 4.2" fan guard with foam for a filter $5CDN, and 4.2" fan gaurd with screening (window screening) for $3.80CDN.
[19:13:57] <jmkasunich> Jymmmm: a 4-8" hole would work for an inlet, or a 1/4-1/2" gap at the bottom, all the way around
[19:14:02] <jmkasunich> or a number of other things
[19:14:24] <jmkasunich> I bet the gap all the way around might be easiest, but you might have some dust escaping if the airflow into the box isn't uniform
[19:14:47] <jmkasunich> where its going in fast, no problem, but if there are spots where the airflow is slow or none, dust might escape
[19:15:16] <jmkasunich> (is this a complete enclosure, or an open bottomed box that just sets over the machine and on the table?
[19:16:11] <Jymmmm> jmkasunich: completed closed, gimme a few and I post pics.
[19:16:24] <jmkasunich> ok, forget what I said about a bottom gap
[19:17:34] <unter_e> jmk, were you going to drive step/direction with a Mesa 7I37?
[19:17:57] <jmkasunich> yes
[19:18:03] <jmkasunich> no
[19:18:06] <jmkasunich> ;-)
[19:18:16] <jmkasunich> yes, with a 5i20
[19:18:24] <jmkasunich> not with a 7i37
[19:18:28] <unter_e> directly, no interface board
[19:18:40] <jmkasunich> right, directly
[19:18:54] <a-l-p-h-a> woohoo! it's not me pestering jmkasunich about the mesa. :D
[19:18:55] <jmkasunich> the 7i37 is made for turning stuff on and off slowly (less than 1000 times a second)
[19:19:11] <jmkasunich> but the 5i20 can do 100,000 steps per second (or more)
[19:19:45] <unter_e> I don't think I will do step/direction, I have electrocraft drives that will take analog or s/d
[19:20:20] <jmkasunich> 7i33 will give you analog (the 5i20 does PWM, and the 7i33 filters it into an analog signal)
[19:20:38] <unter_e> I bought a 7i33
[19:21:27] <unter_e> right now I'm just thinking through the inputs/outputs like drive enable, limit switches and estop
[19:22:13] <unter_e> is the problem with the encoder in the current firmware fixable?
[19:23:28] <jmkasunich> the first 4 encoders of the current firmware work fine and always have
[19:23:36] <jmkasunich> the extra 4 are the ones with a problem
[19:23:50] <jmkasunich> and I think that has been fixed too, but I'm not sure if those fixes are in 2.1.2
[19:24:14] <jmkasunich> when I release the step/dir version, it will also have fixed encoders
[19:48:45] <Jymmmm> Ok, the walls are skinned with aluminum screen (with grounding straps), then clear vinyl:
[19:49:08] <Jymmmm> http://farm1.static.flickr.com/149/424362153_e80fc2eb16.jpg
[19:49:31] <Jymmmm> http://farm1.static.flickr.com/149/424362199_da3833a83c.jpg
[19:49:58] <Jymmmm> http://farm1.static.flickr.com/167/424362247_9bce9d31df.jpg
[19:50:20] <Jymmmm> http://farm1.static.flickr.com/166/424362252_1bd7946026.jpg
[19:50:23] <jmkasunich> ok, so to attach the dust collector, you'd have to cut a hole somewhere
[19:50:47] <Jymmmm> in the last photo, you can see where I made a panel for the cabling to go thru
[19:50:57] <Jymmmm> (sort see it that is)
[19:51:01] <Jymmmm> sorta
[19:51:03] <jmkasunich> the whitish rectangle in the back
[19:51:04] <jmkasunich> ?
[19:51:20] <Jymmmm> Yeah, larger image here: http://farm1.static.flickr.com/166/424362252_1bd7946026_b.jpg
[19:52:07] <jmkasunich> that dust collector has a 4" port
[19:52:08] <Jymmmm> the cbaling is going thru a 2" hole, then surrounded with foam
[19:52:17] <jmkasunich> dunno if it has any hose with it or not
[19:52:20] <jmkasunich> probably not
[19:52:26] <Jymmmm> none
[19:52:35] <Jymmmm> thus the nickle and dimed to death comment =)
[19:53:15] <jmkasunich> I'm tempted to suggest cutting a 4" hole in the surface that the rack sits on
[19:53:17] <Jymmmm> The entire enclosure is "bolt together", so I can always pull off the rear wall easily enough
[19:53:45] <jmkasunich> s/rack/machine/
[19:54:11] <jmkasunich> so you could just sweep the heavy dust into the hole when you open the doors
[19:55:04] <Jymmmm> I've been temped,
[19:56:10] <jmkasunich> home depot has a really crappy search engine
[19:56:18] <Jymmmm> lol
[19:56:42] <Jymmmm> just figuring that one out huh? Try sears.com search for dust collect
[19:56:54] <Jymmmm> they have lots of blast gates and other such things
[19:57:01] <skullworks-PGAB> they want you to come in person, and impluse buy...
[19:57:22] <Jymmmm> http://www.sears.com/sr/javasr/search.do?BV_UseBVCookie=Yes&keyword=dust+collection&vertical=TOOL
[19:59:45] <Jymmmm> http://www.sears.com/sr/javasr/product.do?cat=Wet-Dry+Vacs&pid=00921389000&vertical=TOOL&subcat=Dust+Collection+Systems+%26+Attachments&BV_UseBVCookie=Yes
[20:00:01] <jmkasunich> http://www.mcmaster.com/catalog/113/gfx/small/55275kp1s.gif
[20:00:21] <jmkasunich> home desperate sells hose like that for pretty cheap
[20:00:30] <jmkasunich> metalized, no static buildup
[20:00:48] <jmkasunich> that kit from sears is pricy
[20:01:28] <Jymmmm> hw store probably has dryer hose like that too
[20:02:07] <jmkasunich> 4" hole in the floor of the cabinet, near the front, and piped (hosed) to the dust collector.....
[20:02:20] <jmkasunich> then some opening in the back to let fresh air in
[20:02:31] <Jymmmm> jmkasunich did you see the canvas?
[20:02:34] <jmkasunich> yes
[20:02:46] <jmkasunich> I have no idea how much air can get in thru that
[20:02:49] <Jymmmm> it's not THAT dense - cheap stuff
[20:03:08] <jmkasunich> you could try with no inlet hold
[20:03:10] <jmkasunich> hole
[20:03:18] <Jymmmm> were not talking artist canvas, were talking house painter drop cloth type canvas
[20:03:36] <jmkasunich> just keep one hand on the blower switch, so if it starts to suck your walls in, you can turn it off
[20:04:03] <Jymmmm> yeah, it took me 10 days to skin that thing.
[20:04:19] <jmkasunich> the speed control would help there - you can start slow and gradually turn it up
[20:05:03] <jmkasunich> 1/5 of that dust collector's full flow would be enough to control floating dust and heat
[20:05:18] <Jymmmm> and gawd help me if I ever accidentlly bump the control =)
[20:05:24] <jmkasunich> the full flow is for if you are trying to suck up the heavier dust and chips
[20:05:47] <Jymmmm> ok, that makes sense.
[20:05:47] <jmkasunich> well, if the canvas is porous enough it will be ok
[20:05:58] <toastydeath> also be aware dust collectors have a minimum flow rating
[20:06:00] <jmkasunich> if its not porous enough, I'd make it more porus
[20:06:13] <toastydeath> they need to flow a certain CFM in order to work properly and not burn out
[20:06:18] <Jymmmm> I was hoping 8 sw ft would be good enough.
[20:06:24] <Jymmmm> sq
[20:06:31] <jmkasunich> toastydeath: thats true for a fixed speed dust collector
[20:06:38] <Jymmmm> 8sq ft -vs- 4"
[20:06:42] <toastydeath> oh, you're looking at something else?
[20:06:45] <toastydeath> i'll shut up then
[20:06:49] <toastydeath> CARRY ON GOOD SIRS
[20:08:09] <jmkasunich> heh
[20:08:29] <jmkasunich> he's gonna put a speed control on it - its a HF cheapie with a router type (brushes) motor
[20:08:37] <jmkasunich> so he can slow it down
[20:09:01] <Jymmmm> http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=43060

[20:09:56] <jmkasunich> Jymmmm: the canvas might be porous enough already
[20:10:01] <jmkasunich> only way to tell is try it
[20:10:40] <Jymmmm> yeah, I tried to overkill a bit, yet still let light in and keep dust in
[20:11:41] <Jymmmm> I never expected the enclosure to keep SO MUCH HEAT in though
[20:12:34] <Jymmmm> This is a new router (warranty replacement), it might be overheating too. First time use since I got it.
[21:01:44] <skullworks-PGAB> Just read Emc-users Digest, Vol 11, Issue 32 - and all the research done to debunk Paul C.'s FUD report.
[21:02:32] <skullworks-PGAB> guess in a prior life he had ambitions of being a lawyer
[21:02:57] <jepler> skullworks-PGAB: I just tried to read his last message
[21:03:06] <skullworks-PGAB> a Persecutor
[21:03:53] <jepler> skullworks-PGAB: he sure uses a lot of words
[21:04:36] <toastydeath> i can use lots of words!
[21:04:48] <skullworks-PGAB> text pattern camoflage
[21:06:16] <skullworks-PGAB> text pattern smoke screen too
[21:08:02] <toastydeath> at least he wasn't incorrectly quoting nietzsche
[21:08:06] <toastydeath> OR WAS HE

[21:36:30] <CIA-6> 03jepler 07v2_1_branch * 10emc2/debian/changelog: note image-to-gcode changes
[21:36:59] <cradek> soon I'll have to go through the diffs to see what things I backported but didn't put in the changelog
[21:37:20] <jepler> what fun
[21:38:01] <skullworks-PGAB> what servo amps were you using to drive your lathe with the pluto?
[21:40:29] <cradek> just a L298 dual h bridge
[21:40:41] <cradek> at 24v
[21:41:40] <skullworks-PGAB> single chip - 2A per axis?
[21:42:02] <cradek> yes
[21:42:08] <skullworks-PGAB> or paralleled 1 chip per axis?
[21:42:11] <skullworks-PGAB> ok
[21:42:14] <cradek> one chip for 2 axes
[21:42:35] <cradek> it's beautifully simple
[21:43:45] <skullworks-PGAB> I was going to try a few paralleled L298's but I worry that a motor stall would let the majic smoke out
[21:44:59] <cradek> yeah I worry about that too, but my machine will quickly stop with a following error if there's any kind of stall
[21:45:25] <cradek> the ferrors are set pretty tight
[21:45:27] <skullworks-PGAB> what about a motion reversal at g00?
[21:45:28] <jepler> the lack of current limit is disturbing
[21:46:37] <cradek> I figure it's easy to replace it, I'll blindly go on with it this way - if the smoke comes out I'll do something smarter
[21:47:51] <skullworks-PGAB> I have some Globe No. 21's and some Pittman 14 series but I worry that they will over draw at peak surge.
[21:48:17] <skullworks-PGAB> not sure if a fastblow fuse would be FAST enough
[21:48:26] <cradek> these are pittman mystery motors marked 19.1V
[21:48:35] <skullworks-PGAB> no
[21:48:51] <cradek> I mean that's what I have
[21:48:59] <skullworks-PGAB> Pittman 14203 and 14437
[21:49:05] <jepler> the l298 datasheet says the 100uS non-repetitive current is 3A per channel which isn't much
[21:49:10] <jepler> I bet you'll get away with more in practice
[21:49:43] <skullworks-PGAB> I was thinking of paralleling 3 chips
[21:49:55] <skullworks-PGAB> I got a bunch cheap
[21:50:34] <skullworks-PGAB> and using a FAT heatsink
[21:51:18] <jepler> I haven't seen multiple L298 packages in parallel before
[21:51:33] <skullworks-PGAB> jepler: true but only 2A/ch for true DC
[21:53:19] <skullworks-PGAB> I saw a guy running a fat Nema 34 using a single 297 to drive 3 paralleled 298's in halfstep
[21:54:18] <skullworks-PGAB> have not seen it used as I intend for a non-stepper application
[21:55:33] <skullworks-PGAB> I mentioned this elsewhere (I forget) and was advised that it should worl provided I retain the caps as shown on the data sheet
[21:56:28] <jepler> just steal that board, pop the l297 out of its socket, and put some jumper wires
[21:56:37] <jepler> you'll be running your servo motor in no time
[21:57:05] <skullworks-PGAB> Still have to rig encoders
[21:57:22] <jepler> true
[21:57:45] <a-l-p-h-a> hey Q... shouldn't this channel be ##emc, and #emc for devel?
[21:58:11] <skullworks-PGAB> Well I'll draw up the PCB and make it the hard way.
[21:58:47] <skullworks-PGAB> (drawn in CAD and milled/drilled)
[21:59:29] <unter_e> I was looking at the specs for the relays I bought wishing that I had gotten the ones with reverse protection diodes.
[21:59:54] <unter_e> turns out buying the protection diodes doubles the price of the relay
[22:00:02] <skullworks-PGAB> thankfully I have access to a 12,000 rpm Okuma to do it.
[22:03:27] <unter_e> anyone ever used a linux cad program, I'd like to draw up my control cabinet schematics
[22:04:30] <alex_joni> unter_e: use Eagle
[22:04:57] <alex_joni> http://www.cadsoft.de/
[22:08:04] <unter_e> I thought about that, but concluded it might be too rigid
[22:08:15] <unter_e> I've seen some really nice schematics in autocad
[22:09:05] <alex_joni> not regular autocad though
[22:09:17] <alex_joni> there are loads of extensions for autocad
[22:09:33] <alex_joni> e.g. Mechanical Desktop
[22:10:29] <unter_e> I am messing around with qcad
[22:25:02] <tomp>
[22:31:01] <Jymmmm> ok, I'm off to HF... laters
[22:45:15] <CIA-6> 03jepler 07v2_1_branch * 10emc2/docs/src/gui/ (image-to-gcode.lyx image-to-gcode.png): add image-to-gcode documentation

[22:45:42] <CIA-6> 03jepler 07v2_1_branch * 10emc2/debian/changelog: note new documentation was added
[23:35:04] <twice2> with v2.1.2 is it possible to share home and limit switches?
[23:36:14] <skullworks-PGAB> should be
[23:36:19] <alex_joni> twice2: still the same as 2.1.1, nothing happened
[23:36:21] <alex_joni> skullworks-PGAB: yes and no
[23:36:36] <skullworks-PGAB> ?
[23:36:43] <alex_joni> skullworks-PGAB: you can share them, but it's a problem if you home axis X and the limit on Y gets activated
[23:36:58] <alex_joni> I think twice wants to share ALL home and limit switches on one input
[23:38:15] <twice2> thanks, yes all swithces wired to one pin
[23:39:43] <skullworks-PGAB> * skullworks-PGAB plans to wire each axis to one pin
[23:40:05] <alex_joni> skullworks-PGAB: that works without problms
[23:40:08] <skullworks-PGAB> one prox switch in center
[23:40:22] <twice2> actually homing works fine, as long as i don't connect anymore than one limit in hal. If I do then nothing homes only limits are active
[23:40:35] <skullworks-PGAB> so it triggers for either direction
[23:40:58] <skullworks-PGAB> as a limit
[23:41:19] <toastydeath> push it to the limit
[23:41:22] <toastydeath> walk along the razor's edge
[23:41:25] <toastydeath> etc etc
[23:41:29] <twice2> that's an idea! but no here are just 5 micro
[23:42:35] <alex_joni> skullworks-PGAB: emc2's current issue twice2 is hitting, is that there is a limit ignore switch while homing
[23:42:46] <alex_joni> but that does only work for the axis currently beeing homed
[23:44:13] <skullworks-PGAB> so if after homing 1 axis he isn't far enough off the switch a faulty home might be set for the next axis?
[23:44:44] <alex_joni> skullworks-PGAB: if you connect all homes and all limit switches to one single pin
[23:45:04] <alex_joni> then if you hit the home limit on axis x, simultaneously all other limits/homes will be activated
[23:45:17] <alex_joni> X min & max limit won't matter, as they are deactivated
[23:45:26] <alex_joni> but Y min & max, Z min & max, etc will trip an error
[23:48:26] <skullworks-PGAB> so there need to be a mod to only set home for the current single active axis?
[23:49:58] <twice2> skullworks-PGAB: you are correct, with all on one pin if I don't set home_offset enough then I would get limit error
[23:50:05] <alex_joni> if you use one pin / axis, then it's ok
[23:50:28] <alex_joni> twice2: using home_offset & home clears the error?
[23:51:06] <skullworks-PGAB> needs a function like a Haas mill - Home single axis
[23:51:22] <twice2> if i share one it does
[23:51:54] <twice2> tkemc does
[23:51:55] <skullworks-PGAB> * skullworks-PGAB hate Haas only a little less than Mazak.
[23:53:21] <twice2> i dunno, not being cheap skate, i can buy more switches but i have pin plans
[23:53:33] <skullworks-PGAB> Working with like 20 different machine makes a day sure refines ones preferenes.
[23:53:46] <skullworks-PGAB> add a second LPT port?
[23:55:06] <twice2> and cable and connections, sure i could
[23:55:39] <twice2> we can never have enough wires :)
[23:56:03] <skullworks-PGAB> daisy vrs star
[23:56:28] <skullworks-PGAB> oops thats wrong
[23:56:37] <skullworks-PGAB> not star
[23:58:11] <twice2> dunno, i'm old, i remember ge1050
[23:59:03] <skullworks-PGAB> * skullworks-PGAB still has a coffee can full of film can of paper tape progs
[23:59:28] <twice2> hehe
[23:59:33] <skullworks-PGAB> from the 1050 and Bandit days
[23:59:42] <twice2> tally ho
