[00:21:59] <r00t4rd3d> should my plunge rate be half of my ipm rate?
[00:22:57] <r00t4rd3d> i thinks that what i read somewhere and what i currently do
[00:29:57] <Tom_itx> good place to start, yes
[00:30:08] <Tom_itx> ramp or plunge?
[00:30:24] <Tom_itx> i don't like either unless it's unavoidable
[00:33:02] <r00t4rd3d> plunge, right now it just goes straight down in to the wood
[00:33:13] <r00t4rd3d> what should i be doing?

[00:35:00] <Tom_itx> in wood it likely won't matter
[00:35:16] <r00t4rd3d> the only options i only have ramp options besides plunge
[00:35:25] <r00t4rd3d> -only
[00:35:29] <Tom_itx> if i'm cutting into a closed pocket, i like to ramp in if possible
[00:35:38] <Tom_itx> or predrill a hole and plunge into it
[00:35:47] <Tom_itx> but that's not so efficient
[00:36:12] <Tom_itx> so hand edit it
[00:36:15] -!- Loetmichel has quit [Ping timeout: 272 seconds]
[00:36:44] <r00t4rd3d> i mainly use carbide bits that are made for plunge cuts
[00:37:02] <r00t4rd3d> they got the teeth on the bottom
[00:37:43] <r00t4rd3d> my ipm is 12 so waiting for 6 sucks
[00:38:33] <r00t4rd3d> i need a new controller
[00:38:39] <r00t4rd3d> 12 sucks too
[00:39:57] <Tom_itx> won't go faster than 12?
[00:40:11] <r00t4rd3d> nope
[00:40:28] <Tom_itx> well you can probably plunge at that rate or ramp
[00:40:59] <r00t4rd3d> i use threaded rod from the hardware store for 2 of my lead screws, i dont think that helps my speed much either

[00:43:24] <r00t4rd3d> if i turn up the velocity, my motors just make weird noises
[00:44:05] <r00t4rd3d> its at 0.2 atm
[00:44:10] <Tom_itx> get some good drivers
[00:44:15] <Tom_itx> makes all the difference
[00:44:41] <Tom_itx> i did that and increased the motor voltage by double
[00:44:54] <r00t4rd3d> i have a good supply too
[00:45:07] <Tom_itx> i got 50v going to my drivers
[00:45:29] <r00t4rd3d> mine is 24v but i have it turned down to 18
[00:45:45] <Tom_itx> you saw mine didn't you?
[00:45:52] <r00t4rd3d> ur power yeah
[00:45:58] <Tom_itx> in action

[00:56:08] <Sub-> well, there's a room on freenode for everything it seems
[00:56:36] <Connor> Tom_itx: What kind of mill is that ?
[00:56:49] <Tom_itx> sherline
[00:58:03] <Tom_itx> there's one actally cutting something: http://www.youtube.com/watch?v=-CEqokrtFI4&feature=youtu.be
[00:58:42] <FinboySlick> Tom_itx: Wow, that runs terribly smooth for a sherline... Did you do anything to the ways?
[00:58:57] <Tom_itx> no just adjusted stuff
[00:59:10] <Tom_itx> added a counterweight to z to offset the motor
[00:59:20] <FinboySlick> I have a non-CNC version of that mill.
[00:59:25] <FinboySlick> It needs lots of TLC.
[00:59:33] <Tom_itx> time to add some motors to it
[01:00:16] -!- r00t-Shed [r00t-Shed!~CNC@cpe-67-249-21-218.twcny.res.rr.com] has joined #linuxcnc
[01:03:31] <FinboySlick> Hmmm, while I see you milling plastic... Is a fast spindle better or worse for nylon? I have a project that I plan to mill with a 1/8 2flute and I can't really spin below 8kRPM.
[01:04:13] <Tom_itx> it'll burn if you go too slow probably
[01:04:18] <Sub-> would someone confirm the linuxcnc set up for me please? I'd like to be sure I understand properly (very new at this)… I have a modest pc running linuxcnc, this connects via a parallel port/cable to something like a geckodrive controller unit (please shout up if there is a better choice for a new guy), and my steppers connect to the gecko. Is this right? I assume I need a PSU, do I run power directly into the gecko type controller unit f
[01:04:18] <Sub-> the steppers?
[01:04:20] <Tom_itx> kick up the feedrate
[01:04:34] <FinboySlick> That'll be scary :P But the mill can move fast.
[01:04:51] <FinboySlick> I guess I should look for a specific chipload and stick to it.
[01:04:53] <Tom_itx> sub, yes pretty much
[01:05:04] <Tom_itx> yeah
[01:05:10] <Tom_itx> i got a reference here...
[01:05:38] <Tom_itx> http://www.onsrud.com/plusdocs/Doc/index.html?model.code=FeedSpeeds
[01:05:45] <Sub-> Tom_itx: thankyou. What about first positioning reference, do i connect some limit microswitches into the gecko for a start up calibration?
[01:06:19] <Tom_itx> i used a pair of mesa cards between my parport and the gecko drives
[01:06:25] <Tom_itx> makes life nicer
[01:06:55] <Sub-> mesa cards eh, no idea what they are /me googles
[01:07:09] <FinboySlick> Tom_itx: Thanks, that'll help. I was going to see if CNC Cookbook could help but I might have to budget for it, my trial expired.
[01:07:14] <Tom_itx> http://www.mesanet.com/
[01:07:41] <Tom_itx> FinboySlick, i added a couple more links at the top here: http://tom-itx.dyndns.org:81/~webpage/cnc/psu/psu_index.php
[01:07:48] <Tom_itx> for lack of a better place to put htem
[01:08:31] <Tom_itx> Sub-, i'm using the 7i43 and 7i47 but the 5i25 would be a nice card for a pci buss
[01:08:32] <jp__> PCW must be happy with all of us mesa lovers!!!
[01:08:48] <Sub-> Tom_itx: ty, reading now
[01:08:51] <Tom_itx> most of their business is commercial i bet
[01:09:14] <PCW> Yeah but the LinuxCNC stuff is more fun
[01:09:15] <Tom_itx> Sub-, look under anything io cards
[01:09:19] <Tom_itx> and daughter cards
[01:09:35] <Sub-> yep, got it
[01:09:36] <Tom_itx> or just bug the crap outta PCW and make him earn his keep

[01:14:35] <Sub-> im interested in using linuxcnc for a lightweight delta robot, so don't need milling type torques and will be using low current nema 17 steppers. These run fine in my RepRap on the cheap Pololu stepper drivers, can I use that sort of set up initially with linuxcnc?
[01:14:54] <Tom_itx> probably
[01:15:08] <Tom_itx> you gonna print with it?
[01:15:28] <Tom_itx> did you make a roStock?
[01:15:51] <Sub-> no, use it as a base to develop a computer vision system… i want it to be able to "see" it's workspace, then identify and classify objects and pick up/sort them

[01:29:19] <jp__> man i need to get my printer working too much cool stuff too print!!
[01:29:27] <FinboySlick> Sub-: That looks like some pretty good 3d printing quality, is that a reprap?
[01:29:31] <Sub-> what kind you got jp?
[01:29:41] <jp__> my own design
[01:29:45] <Sub-> FinboySlick: yeah, it's a little reprap huxley

[01:31:47] -!- morfic has quit [Ping timeout: 244 seconds]
[01:31:47] <jp__> guess i could of just slapped an extruder to my mill!!
[01:32:02] <jp__> that would of been eaiser
[01:32:22] <FinboySlick> jp__: Now that's a great idea.
[01:32:33] <Sub-> mill probably moves a lot slower than is ideal for aprinter?
[01:32:41] <Sub-> should work though
[01:33:07] <jp__> my kit VMC moves pretty dam fast
[01:33:11] <FinboySlick> Sub-: Mine moves fast enough but it's probably going to be wasting quite a bit of energy in the process.
[01:33:43] <Sub-> yeah
[01:33:48] <FinboySlick> It'll probably go through the floor too.
[01:33:55] <jp__> Thats why i did not kkinda a pita to fire up the phase converter just to run a print
[01:33:57] * FinboySlick needs to strengthen it.
[01:34:25] <Sub-> the new prusa i3 is due before long
[01:34:30] <Sub-> that looks good
[01:35:04] <jp__> Tried to cut a nozzle with a laser today
[01:35:14] <Sub-> ?
[01:35:14] <jp__> need more power
[01:35:25] <jp__> the orfice
[01:35:45] <Sub-> i'd imagine anything you can laser cut isn't suitable for a nozzle? surely it would soften/melt at extrusion temperatures
[01:35:50] <FinboySlick> jp__: edm and a needle?
[01:36:11] <jp__> good idea
[01:36:24] <jp__> 30 wat yag on alum sucked
[01:36:36] <Valen> you can laser steel ok
[01:36:44] <Valen> Al is going to be too reflective
[01:37:34] <Valen> well you heat it with the laser, then the air blows the hot steel out of the way/burns it with O2
[01:37:35] <jp__> i tested it out on steel and then went ahead and machined my blanks out of alum

[01:37:43] <FinboySlick> I know that you can color metals with a laser. I wonder if it would be energy efficient to darken, blast, darken, blast.

[01:38:05] <Valen> they colour it with a moly-sulphide powder
[01:38:17] <Valen> it really just changes the chemical composition at the surface
[01:38:24] <Valen> well for steel etching anyway
[01:38:44] <Valen> for Al they anodise it and the laser kills the dye selectivly

[01:39:07] <FinboySlick> What I read was on aluminium... They apparently created the blackest black that way. (Cue Dethclock)
[01:39:41] <FinboySlick> I'm pretty sure it was just modulating temperature but I'm not sure.
[01:39:41] <Valen> yeah, surface treatment only though and with advanced magic to boot
[01:39:45] <jp__> different wavelength probably
[01:40:51] <ScribbleJ> When I cut acrylic with my laser it leaves behind this sticky smelly acrylic resin I guess.
[01:41:20] <jp__> That happens with my sawzall too!! lol
[01:41:45] <ScribbleJ> Is it a laser sawzall?!

[01:43:14] <L84Supper> FinboySlick, which blackest black was this that you read about?
[01:43:33] <L84Supper> I type too slow :)
[01:43:58] <FinboySlick> L84Supper: Hehe... Seriously, it was an article on Slashdot years ago.
[01:45:31] <FinboySlick> I just remember it because I was thinking: Superblack on aluminium: Solar heating.
[01:45:46] <FinboySlick> But I'm Canadian so it's moot.

[01:48:26] <FinboySlick> jp__: I'm just glad we've got a minority government. The less these jerks can do the better off we are.
[01:48:41] <FinboySlick> And I consider that valid for all parties.
[01:49:15] <jp__> Im in Ontario with a minority as well but different jerks
[01:53:49] <Valen> you can still do solar heating even if its cold
[01:54:09] <Valen> hide your heat soakeruper behind some glass insulation
[01:54:52] <FinboySlick> Valen: I know, I was just being stereotypical :)
[01:55:24] <Sub-> heat soakeruper, that's a technical term, is it? ;)

[01:59:58] <Valen> which wiki?
[02:00:02] <jp__> ah got it

[02:02:14] <tjb1> Best all purpose tap would be a plug?
[02:02:40] <Tom_itx> depends on the purpose :)
[02:02:56] <tjb1> all ;)
[02:03:07] <FinboySlick> tjb1: tap as in threads?
[02:03:23] <tjb1> yessum
[02:03:36] <Sub-> you dont' want a plug
[02:03:38] <Tom_itx> spiral point tends to shove the shavings out the hole
[02:03:41] <Sub-> plug is for bottoming
[02:03:50] <Tom_itx> a bottoming tap isn't good for starting threads
[02:03:55] <Sub-> exactly
[02:04:07] <tjb1> No sub, a bottoming is for bottoming
[02:04:09] <Tom_itx> a spiral flute tap would be better for production
[02:04:24] <Sub-> same thing, we call a plug a bottoming tap
[02:04:30] <tjb1> its not the same thing
[02:04:41] <tjb1> bottoming have almost no taper at all
[02:04:47] <Tom_itx> then the answer is no
[02:05:12] <FinboySlick> tjb1: If you don't have to go deep, or fast, SPTM is an interesting approach too.
[02:05:36] <tjb1> This is a hand jobber ;)
[02:05:53] <Sub-> tjb1: i stand corrected
[02:05:56] <FinboySlick> It's starting to sound dirty.

[02:10:27] <uw> but really, that's also some of the advice I'd be looking for
[02:10:28] <Valen> what is the end use of it?
[02:10:59] <uw> I'd like to cut plastic and wood 1/4" thick
[02:11:10] <jp__> you can get cheap co2 kits

[02:17:11] <tjb1> and the tap since my school has nothing metric
[02:17:12] <Valen> and its shit lol

[02:25:37] <Valen> whats the point?
[02:26:26] <L84Supper> fewer machines, faster
[02:27:43] <jp__> Additive vs billet or forging or casting
[02:29:45] <Valen> i mean if you are additive then why machine
[02:30:28] <jp__> form probably
[02:30:40] <L84Supper> the SLS is much lower precision than the milling, by having them in the same machine you can machine each layer
[02:31:18] <L84Supper> well, their method of SLS
[02:31:53] <Valen> you could make the sls better ;->

[02:56:55] <Valen> I'm happy to be around lots of chemicals, but cyanide is a nono

[02:59:12] <Aero-Tec> can one mirror a part easy?
[02:59:26] -!- phreak [phreak!~phreak@65.102.12.159] has joined #linuxcnc
[02:59:27] <Aero-Tec> like scale -1?
[02:59:50] <Tom_itx> some machines will mirror a cutter path but it also reverses the cut direction
[02:59:52] <Valen> thats generally something one would do in the CAM
[02:59:56] <Aero-Tec> is there any scale option in EMC
[02:59:59] <Tom_itx> ie if it was conventional it will climb
[03:00:14] <Tom_itx> it's not always a good idea
[03:00:28] <Tom_itx> i'd rather fix the paths in a cad cam first
[03:00:47] <Aero-Tec> ok

[03:01:24] <Valen> i wonder if the cord-rotation would do it?
[03:01:31] <Aero-Tec> is there a scale option in EMC?
[03:02:33] <Valen> uhh, kinda but not really
[03:02:40] <Valen> you could change the machine scale
[03:02:46] <Valen> but that sounds like a bad plan
[03:02:52] <Valen> what are you actually trying to do?
[03:03:08] <Aero-Tec> so not like mach where it has a part scale
[03:03:35] <Valen> why would you want to do that?
[03:03:56] <Aero-Tec> cool option
[03:04:03] -!- Keknom has quit [Quit: Leaving.]
[03:04:04] <Aero-Tec> can be handy

[15:16:41] <Dolence> someone could please tell answer me a thing about home/limit switches?
[15:17:48] <jdh> ask
[15:18:13] <Dolence> limit switches are expected to be after or before home switches? when I do a home scan, I noticed that limit switches act too... activating E_STOP
[15:19:09] <jdh> you can tell homing to ignore limits, but afaik, that setting is mainly for using shared home/limit
[15:19:30] <jdh> I can't think of another situation where you would want the machine to ignore hard limit switches.
[15:19:41] <Dolence> I'm using 1 pin to all 3 limit switches and individual input pins to the 3 home switches
[15:20:07] <jdh> for your first axis, where is the home in relation to the limits?
[15:20:59] <Dolence> almost together, with limit being activaded before (almost same time) reaching home
[15:21:31] <jdh> that would seem to be a bad idea, IMO.
[15:21:49] <jdh> why would you want to home outside the hard limits of the axis?
[15:22:12] <Dolence> I dont, a friend of mine give thsi amchien to me, so I'm trying to modernize it
[15:22:30] <Dolence> ok, but lets say I rearrange switches positions
[15:22:44] <jdh> move the home switch inside the limits.
[15:23:05] <jdh> but, you have to tell it to home + or -. If you are on teh 'wrong' side of the home switch, you might be moving in the wrong direction.
[15:24:22] -!- mozmck has quit [Ping timeout: 250 seconds]
[15:25:12] <Dolence> jdh how could I do that? yesterday, to have a right homing scanning I had to change scale to a negative parameter
[15:26:23] <jdh> you can share a single pin for all limits and homes. You just have to make sure none of the axes are on a limit/home before homing.
[15:26:57] <jdh> I would suggest getting rid of the individual home switches and use shared home/limits per axis.
[15:27:23] <Dolence> ok
[15:28:04] <Dolence> I deactivated all limits to be able to test the machine
[15:28:12] <Dolence> homming worked like a charm
[15:28:43] <Dolence> but after that, i tried to move the axis using directional and it moved only 0.1" on each axis
[15:28:54] <jdh> if you always home, and never lose position, and have correct soft limits, it's almost, but not quite, like having hard limits
[15:29:24] <Dolence> ok, i think i dont have soft limits setted yet
[15:29:41] <Dolence> don't figured out how to set yet
[15:29:54] <Dolence> becasue after homing, each axis move only o.1"
[15:29:59] -!- mozmck [mozmck!~moses@client-74.117.92.175.dfwtx.partnershipbroadband.com] has joined #linuxcnc
[15:29:59] <Dolence> 0.1
[15:30:33] <jdh> I have machines with separate limits/home at work. When you tell them to home, they go whatever direction specified until they hit a limit or home. If they hit a limit, they go the other direction until they hit home.
[15:30:43] <jdh> Not sure if linuxcnc has a home sequence like that.
[15:31:00] <jdh> and it doesn't really seem to add much.
[15:32:43] <Dolence> ok, ty very much jdh
[15:32:51] <Dolence> i will try to figure out how to set soft limits
[15:33:05] <Dolence> because right now, each axis move no more them 0.1"
[15:33:44] <jdh> does it display an error when it stops?
[15:34:06] <Dolence> let me see
[15:36:48] <Dolence> no, no error message
[15:37:45] <jdh> what are MIN_LIMIT and MAX_LIMIT in your .ini for teh axis?
[15:38:48] <Dolence> min limit -0.01
[15:39:04] <Dolence> max limit was 0, but i changed it to 5000 witout success
[15:39:32] <jdh> what is HOME?
[15:39:42] <jdh> and HOME_OFFSET?
[15:40:17] <jdh> and do your axes move in the correct +/- directions?
[15:40:19] <Dolence> both are zero
[15:41:12] <Dolence> yes, bu i had to change scale to home in the direction of switches
[15:41:22] <Dolence> homing was inverted in relation to switches position
[15:41:34] <Dolence> *reversed
[15:41:59] <jdh> you changed the sign of STEP_SCALE, or HOME_SEARCH_VEL ?
[15:42:34] <Dolence> just the signal
[15:42:38] <Dolence> in scale
[15:43:10] <jdh> if you hit the right arrow, does your cutter move to the right relative to the work?
[15:43:20] -!- archivist_herron has quit [Ping timeout: 252 seconds]
[15:45:01] <jdh> you can invert the homing direction by changing the sign of HOME_SEARCH_VEL
[15:45:21] <Dolence> hmmm
[15:45:29] <Dolence> it seens to be reversed
[15:46:44] <Dolence> i will try it and report
[15:47:04] <Dolence> I have to launch :D~
[15:47:11] <Dolence> by now, thanks you very much

[16:01:31] <IchGuckLive> Did you recive my seconf mail
[16:01:35] <Dolence> how are you?
[16:01:49] <Dolence> Yeah, already downloaded but not tried yet
[16:01:54] <IchGuckLive> tierd after work
[16:02:08] <Dolence> trying to solve linuxcnc config problems
[16:02:21] <IchGuckLive> Maybe there is also a version in portugese out
[16:02:31] <Dolence> oh, here it's only 01:00 PM
[16:02:46] <IchGuckLive> im 5hr later
[16:02:50] <Dolence> wow
[16:03:02] <IchGuckLive> what is the config problem
[16:03:14] <Dolence> ok, let me explain the scenario to you
[16:03:31] <Dolence> yesterday I was able to figure out the pins used by my machine
[16:03:46] <IchGuckLive> Parport i guess
[16:03:53] <Dolence> yes
[16:03:59] <Dolence> after that, I tried to do a homing
[16:04:20] <IchGuckLive> with or without homepin in use
[16:04:34] <IchGuckLive> are there real home switches
[16:04:40] <Dolence> yeah
[16:04:47] <IchGuckLive> ok
[16:04:52] <Dolence> 3 inputs/switches to home
[16:04:56] <Dolence> and 1 input to all limits
[16:05:11] <Dolence> two problems here, limits are phisically before home switches
[16:05:14] -!- erasmo has quit [Remote host closed the connection]
[16:05:29] <IchGuckLive> That will not work
[16:05:46] <Dolence> ok, I already changed the positions
[16:06:20] <IchGuckLive> Home switches are ignored after homming
[16:06:32] <IchGuckLive> problem now is

[16:06:48] -!- FinboySlick has quit [Ping timeout: 246 seconds]
[16:06:57] <IchGuckLive> one more info do you use stepconf or do it manuell
[16:07:10] <Dolence> second, homing direction was reversed on y and z axis
[16:07:28] <Dolence> so I changed SCALE to a negative parameter
[16:07:36] <Dolence> and them it worked as expected
[16:07:50] <IchGuckLive> you can use a - in the search velocity
[16:08:00] <Dolence> in the velocity, not scale?
[16:08:06] <IchGuckLive> SCALE is always plus
[16:08:15] <Dolence> ahhhhhh...
[16:08:18] <Dolence> now i see
[16:08:29] <Dolence> because after homing, each axis move only 0.1"
[16:08:37] <IchGuckLive> DID you read the integratoer manuell on this
[16:09:10] <IchGuckLive> scale is the stepcount per 1mm if you configure mm mashine
[16:09:47] <IchGuckLive> the infos are on page 26... in the manual
[16:10:02] <IchGuckLive> HOME_SEARCH_VEL is your need
[16:10:18] <IchGuckLive> set it to minus value and it moves the other way
[16:11:12] <IchGuckLive> oh is see we got the HOME_IGNORE_LIMITS So its posibel to home outside the limits

[16:13:31] <Dolence> now it kinda worked
[16:13:45] <IchGuckLive> :D B) O.O
[16:14:00] <Dolence> the problem now is some axis are inverted in relation to work
[16:14:37] <IchGuckLive> invert the Axis first to get your coordinate systrems then resink homing
[16:14:46] <Dolence> only Y is right
[16:15:20] <IchGuckLive> you need to invert the direction pins
[16:15:35] <IchGuckLive> do you use Stepconf ?
[16:15:38] <Dolence> yeah
[16:16:01] <IchGuckLive> hit the arrow box beond XDirection and Z direction

[17:47:44] <r00t4rd3d> 1.0.7
[17:47:59] <IchGuckLive> go back to 1.05
[17:48:29] <r00t4rd3d> you think that will fix it?
[17:48:41] <IchGuckLive> if then the folder is the problem update to 1.06
[17:48:41] <r00t4rd3d> i think thats what is was on when i got it

[17:49:32] <IchGuckLive> its only the SDHC problem fix in the 1.05
