[04:59:48] <r00t4rd3d> ROAR!
[05:05:11] <r00t4rd3d> http://www.liveleak.com/view?i=b5e_1351660242
[05:05:12] <r00t4rd3d> lol
[07:34:04] <JesusAlos> Hi boys n girls
[08:10:59] <jdh> Jesus: and the others too?
[08:49:05] <JesusAlos> ofcourse
[08:51:30] <JesusAlos> omo llevais los preparativos para la noche de halloween?
[08:52:24] <JesusAlos> How you take the preparations for Halloween night?
[09:23:44] <r00t4rd3d> I bought a family sized package of toilet paper.
[09:23:55] <r00t4rd3d> I only had to shit though.
[09:26:05] <r00t4rd3d> My buddy and his old lady didnt discuss who was buying the candy, they each got some and they ended up getting $60 worth of candy and it rained out last night lol.
[10:34:46] <JesusAlos> hi people
[10:34:59] <JesusAlos> i want a question about emc2
[10:35:32] <JesusAlos> there some way to show a time to machining?
[10:35:45] <jthornton> properties
[10:35:51] <JesusAlos> time after finish
[10:41:00] <roh> i have a 'machine uptime counter' with session-reset button in axis
[10:41:08] <roh> custom script
[10:43:22] <JesusAlos> you did it yourself?
[10:43:32] <roh> yep.. mompls
[10:44:19] <JesusAlos> what's mean "mompls"?
[10:44:26] <DJ9DJ> one moment please
[10:44:33] <JesusAlos> ok
[10:44:42] <JesusAlos> BRG
[10:45:11] <JesusAlos> "best regards"
[10:45:42] <jthornton> JesusAlos, if your wanting the current run time there is a time comp
[10:46:15] <Mike24> Hello ! I'm struggling to configure a servo-based spindle with Mesa's 5i25 and 7i77 boards. Motor maximum velocity is greyed out in pncconf (100rpm) and I can't find how to modify it. The encoder output is good. Should I add "loadrt scale etc" (found in the manual) as with a vfd ? Thank you !
[10:47:40] <JesusAlos> i ask is the time until finish
[10:47:46] <JesusAlos> the countdown
[10:52:28] <roh> JesusAlos: http://pastebin.com/X7SgxHch
[10:52:42] <roh> i guess i missed the and an or gate invocations
[10:53:49] <roh> maybe there is a nicer way... thats how i did it
[10:54:08] <roh> need to check on the mill machine where and how the python script is invoked
[10:55:22] <JesusAlos> this code are do youselfe?
[10:55:24] <roh> so its not just copying in, but fixing a few lines..
[10:55:27] <roh> yep
[10:55:42] <JesusAlos> you are programmer so
[10:55:52] <roh> i put a reprap head to our machine as well, so we needed to make some adjustments
[10:56:23] <roh> dunno. i see myself rather as hacker and developer of hard and software.
[10:57:22] <JesusAlos> are aware of my need exposed a few days ago?
[10:59:14] <roh> need?
[11:01:26] <JesusAlos> i need to make a bar similar to axis speed control.
[11:02:14] <JesusAlos> but this bar must control a pause time between each change of direction in a two-axis machine
[11:03:26] <JesusAlos> this pause should not be within gcode
[11:07:43] <jdh> where should it be?
[11:09:17] <JesusAlos> i don't Know
[11:09:56] <JesusAlos> i want to say that ths pause is must be out gcode, because the user need change online it
[11:10:53] <skunkworks> hmm- it would be a lot easier in gcode.. You could pre-proccess the file into axs.. Otherwise - maybe exact stop mode - if 'in position' is activated at each end point - you could maybe use adaptive feed rate and set it to 0... (lots of ifs...)
[11:11:23] <skunkworks> (set it to 0 for an amount of time)
[11:13:07] <jdh> pretty much every time I have used a delay in any type of code, I have always been eventually disappointed.
[11:13:37] <JesusAlos> why?
[11:14:09] <roh> JesusAlos: what is the pause for?
[11:14:17] <jdh> things that need delays don't seem to need the same delay each time.
[11:15:57] <jdh> can you do an m66 for any hal pin?
[11:16:52] <JesusAlos> EPS foam when cutting to a high linear velocity, the hot wire is late and i must to wait for it recover before the change of direction
[11:17:25] <jdh> doesn't that depend on the speed of the move, the density of the foam, the cleanliness of the wire, the current through the wire, etc?
[11:17:46] <roh> hm.. m66 looks nice.. i was using m0 now and was thinking of adding some 'continue' button on the machine
[11:18:15] <Jymmm> JesusAlos: how long is the hotwire?
[11:19:05] <jdh> you could pump a pwm through a pin with the duty cycle being the variable delay time, then preprocess the code to m66 low then high
[11:19:08] <JesusAlos> about 1500mm
[11:19:18] <JesusAlos> http://imagebin.org/234201
[11:19:42] <JesusAlos> is a software to a manufacturer machines
[11:20:24] <Jymmm> JesusAlos: How much of a delay are you needing?
[11:20:33] <Jymmm> to catch up
[11:20:44] <Jymmm> on avg
[11:20:47] <JesusAlos> about 4 seconds
[11:21:28] <roh> wouldnt it be nicer to wait for the wire to be straigtened again?
[11:21:33] <roh> instead of using time
[11:21:40] <JesusAlos> m66 and m0 involves alteration of gcode
[11:21:45] <Jymmm> JesusAlos: OUCH... I think you need to look at increasing your temp controller. Unless you are doing complex cuts, that's huge
[11:21:50] <roh> does the machine measure the tension of the wire?
[11:22:13] <skunkworks> roh's idea seems like a better solution...
[11:22:38] <Jymmm> hot wires are usually spring loaded
[11:23:00] <roh> i mean.. the sw knows the length of the wire if straight.. could one measure the lenght change under load?
[11:23:11] <JesusAlos> the wire have about 180N of tension
[11:23:18] <roh> i guess the head makes them longer as well?
[11:23:19] <JesusAlos> with springs
[11:23:27] <roh> irgh. s/head/heat/g
[11:23:30] <Jymmm> at 60" the hotwire thermally expands on it's own from 4 to 6 "
[11:24:02] <roh> whow. thats a lot
[11:24:06] <Jymmm> Nice idea, just not practical imo.
[11:24:31] <Jymmm> roh: Well, the working temp of NiChrome is 1800F =)
[11:24:51] <JesusAlos> about 90ºC
[11:25:38] <Jymmm> JesusAlos: seriously?! for EPS you need to increase that by at 1.5x
[11:26:00] <JesusAlos> the problem is that you raise the temperature of the wire
[11:26:43] <Jymmm> JesusAlos: Yes, but increase the temp AND constant controlled cnc movement will make for clean cuts
[11:27:08] <Jymmm> JesusAlos: If this was being cut by hand, I understand the lower temps
[11:27:10] <JesusAlos> burn more in the outer faces of the block that in the interior due to
[11:27:37] <Jymmm> JesusAlos: what gauge?
[11:27:47] <JesusAlos> the difference in indoor-outdoor humidity
[11:28:04] <Jymmm> JesusAlos: Well, heat the warehouse =)
[11:29:12] <JesusAlos> note that cut block industrially
[11:29:31] <JesusAlos> about 1500x1500mm of section
[11:29:48] <JesusAlos> and 2500mm of long
[11:30:12] <JesusAlos> speak of pantographs
[11:30:20] <Jymmm> But look at what that 4s delay is doing.... It's holding the wire still at the outside edges, while he middle is still catching up.
[11:30:52] <JesusAlos> for all this, we need pause stop
[11:31:55] <Jymmm> I think you need to look at 1) the hotwire gauge/type and 2) your voltage/amperage, 3) humidity compensation
[11:32:14] <JesusAlos> believe me. It is the best way to work with these sizes
[11:32:32] <Jymmm> what gauge hotwire?
[11:33:02] <JesusAlos> about 0,5mm i think
[11:34:05] <Jymmm> JesusAlos: 30ga at 60"
[11:34:13] <JesusAlos> Jymmm: have much experience in cutting EPS. The best solution is the pause time
[11:34:29] <JesusAlos> What?
[11:34:41] <JesusAlos> 30ga?
[11:34:45] <Jymmm> JesusAlos: Is your controller fixed output voltage?
[11:35:06] <JesusAlos> no
[11:35:10] <JesusAlos> is variable
[11:37:13] <JesusAlos> i need is change in emc2. Not change the way companies operate
[11:37:18] <Jymmm> I'd try a larger gauge hotwire and playing with controller settings
[11:37:50] <Jymmm> intentionally adding a pause/delay is never a good thing in cnc
[11:38:21] <JesusAlos> but, believe me, is necesary in this case
[11:38:42] <Jymmm> JesusAlos: why the precision for such a small hotwire?
[11:39:56] <JesusAlos> is pfor material utilization
[11:40:39] <JesusAlos> is possible the tread may be thicker
[11:41:31] <Jymmm> JesusAlos: tread?
[11:41:56] <JesusAlos> sorry. Wire
[11:42:21] <JesusAlos> is there no way to implement the pause?
[11:43:02] <Jymmm> JesusAlos: Ok, yeah please do try a thicker wire. I think you'll get better results long run, but you'll have to play around with the temp controller to find the sweet spot.
[11:44:18] <Jymmm> JesusAlos: and as you say compensate for humidity and room temperature.
[11:44:52] <JesusAlos> Jymmm: it's no easy for the operator machine
[11:45:17] <JesusAlos> so. the manufacturers machine put stop pause in her software control
[11:45:47] <JesusAlos> and for the moment i no have solution for my machines
[11:46:21] <Jymmm> JesusAlos: I've made hotwires for EPS that are perfect for hand carving sculptures, yet crap for other foams. and even different grades of EPS.
[11:46:53] <Jymmm> JesusAlos: I kind of customize the cutter to the material
[11:48:13] <JesusAlos> Please. I need some reference to do this function in emc2
[11:48:36] <Jymmm> JesusAlos: All I'm trying to say is inducing a delay isn't the right solution long term, it's just a hack imo.
[11:48:54] <hdokes|werkin> Hey Gents, I have a bridgeport series 1 manually operating mill that I would like to retrofit for cnc... is there a source for information on how to size the servo motors for such?
[11:49:37] <Jymmm> JesusAlos: Teach the operator, or get a fancier heat controller to compensate.
[11:49:57] <JesusAlos> Jimmm: I understand your position. But my clients want it
[11:50:02] <Jymmm> JesusAlos: What are you usign for temp control?
[11:50:55] <Jymmm> JesusAlos: a variac?
[11:51:02] <JesusAlos> yes
[11:51:08] <JesusAlos> variac
[11:51:32] <Jymmm> so it's AC on the hotwire?
[11:51:43] <JesusAlos> yes
[11:51:47] <JesusAlos> AC voltage
[11:52:13] <Jymmm> 50Hz AC on a 60" wire == it hums (vibrates)
[11:52:34] <Jymmm> (dont ask how I know that =)
[11:53:48] <Jymmm> JesusAlos: will the client be willing to try a better controller you think?
[11:55:28] <JesusAlos> what you mean?
[11:57:07] <Jymmm> JesusAlos: Will your client be willing to spend the money to try a digitally controlled, environment compensating temperature controller?
[11:57:36] <JesusAlos> is possible
[11:57:42] <Jymmm> $300 - $1000 USD
[11:57:44] <JesusAlos> if i say
[11:57:50] <JesusAlos> is possible
[11:58:14] <JesusAlos> yes i think
[11:59:18] <Jymmm> ok, you might take a look at that for long term solution. Also, I don't think a variac provides isolation to the hotwire like a normal transformer does.
[12:00:25] <Jymmm> You might play with DC instead of AC controller, and see what results you get.
[12:01:19] <JesusAlos> what results you refer?
[12:01:33] <JesusAlos> quality cut or energy saver?
[12:01:48] <Jymmm> JesusAlos: performance (no delays), quality (cleaner cuts)
[12:02:27] <Jymmm> JesusAlos: Nah, in foam cutting there isn't any energy saving ever, MORE POWER!!!! LOL
[12:02:46] <JesusAlos> LOL??
[12:03:00] <Jymmm> JesusAlos: humor
[12:03:14] <JesusAlos> :)
[12:03:56] <jthornton> Jymmm, you on a Linux computer?
[12:04:18] <Jymmm> jthornton: whatcha need =)
[12:04:43] <jthornton> give that a whirl http://www.gnipsel.com/shop/sfc/sfc.xhtml
[12:04:47] <JesusAlos> you know that are companies developing cutting equipament with wires bibrantes EPS?
[12:05:16] <Jymmm> bibrantes ???
[12:06:03] <JesusAlos> bibrate
[12:06:30] <JesusAlos> vibrates
[12:07:02] <Jymmm> you mean AC controllers?
[12:07:07] <JesusAlos> where are you from Jymmm
[12:07:09] <JesusAlos> ?
[12:07:20] <Jymmm> US
[12:07:36] <JesusAlos> no. I mean a mechanical device
[12:08:11] <JesusAlos> in Europe, energetic saving no joke
[12:08:53] <JesusAlos> http://www.tecnodinamica.it/index.php?lang=es
[12:09:03] <JesusAlos> this enterprise developed it
[12:09:12] <JesusAlos> all for enegy saving
[12:09:25] <JesusAlos> less power, more beneficts
[12:09:48] <JesusAlos> and he have pauses stop
[12:20:27] <IchGuckLive> hi all B)
[12:20:46] <tjb1> ello
[12:20:51] <IchGuckLive> JesusAlos: how is it going
[12:21:17] <JesusAlos> bad
[12:21:20] <JesusAlos> :(
[12:21:23] <IchGuckLive> not good
[12:21:26] <JesusAlos> i no have solution
[12:21:40] <JesusAlos> (the solution that i looking for)
[12:22:19] <IchGuckLive> if you go down with the acceleration below 3mm/s² then you might also see a effect you looking for
[12:22:40] <jdh> he wants a 4 second pause
[12:23:05] <IchGuckLive> 4sec on what decission
[12:23:19] <IchGuckLive> 90 deg corner backwards move
[12:27:07] <jthornton> that really should be handled by the post processor and only feed override for the operator
[12:29:07] <IchGuckLive> jt agree on that
[12:32:27] <jdh> I think everyone agrees except jesus
[12:33:12] <jdh> I bet you could hack it in with the backlash compensation
[12:34:12] <jdh> guess that wouldn't work for 90-degree corners though
[12:37:14] <JesusAlos> having seen, may be the solution
[12:37:50] <jdh> perhaps you should use mach
[12:40:13] <JesusAlos> match3?
[12:41:02] <ReadError> mack3
[12:43:42] <pcw_home> mock3
[12:51:22] <tjb1> 4?
[12:51:58] <JesusAlos> why Match?
[12:53:34] <jdh> perhaps they can add a delay for you.
[12:54:24] <tjb1> match? its mach
[12:54:47] <jthornton> mark3
[12:54:53] <tjb1> >:(
[12:55:17] <jthornton> tjb1, want to try something out for me?
[12:55:25] <tjb1> Your gear calc?
[12:55:34] <tjb1> Thread calc sorry
[12:55:58] <jthornton> yea, been improving it a lot http://gnipsel.com/shop/sfc/sfc.xhtml
[12:56:22] <tjb1> What areas do you want tested? or all of it
[12:56:50] <jthornton> just see if it is intuitive to use
[12:57:32] <tjb1> Ill take a crack at it once I get the ambition to go outside, only 39F here :(
[12:57:37] <tjb1> No heat in garage either
[12:57:50] <jthornton> you on a windoze box now?
[12:58:02] <tjb1> mac
[12:58:20] <jthornton> will it run on a mac?
[12:58:26] <tjb1> I tried to put linux on here but it took over and killed windows
[12:58:45] <tjb1> Which one do I click?
[12:59:02] <jthornton> where?
[12:59:10] <tjb1> glade, pyc, sqlite
[12:59:28] <jthornton> oh, sfc.pyc
[12:59:45] <tjb1> Let me see if I can get python
[12:59:53] <jthornton> be nice to know that up front I guess LOL
[13:00:51] <tjb1> It is python correct?
[13:04:24] <IchGuckLive> are there also metric treads in
[13:05:38] <IchGuckLive> its in glade sqlite
[13:12:42] <tjb1> I cant get it to run right on mac jthornton
[13:13:52] <jthornton> ok thanks for trying
[13:14:32] <tjb1> Ill test it out later today
[13:14:55] <jthornton> ok thanks
[13:18:09] <mutilator> so.. etching glass.. anyone do it?
[13:18:23] <mutilator> looking for a new bit
[13:19:27] <awallin> mutilator: what do you want to do in glass?
[13:19:53] <mutilator> etching mirrors
[13:20:39] <awallin> I've used saturated KOH solution to clean microscope coverslips. that is supposed to etch away a bit of the surface.
[13:21:05] <mutilator> i was just using diamond bi
[13:21:06] <mutilator> bits
[13:21:12] <awallin> we used Teflon/PTFE holders for the glass in KOH. don't put metal in the KOH
[13:21:16] <mutilator> but all the ones i had laying around were just crappy things
[13:21:44] <awallin> so you want some pattern etched, like making a pcb?
[13:21:52] <mutilator> yea
[13:22:22] <awallin> I guess they sell the photoresist for pcb-making as a spray?
[13:22:49] <mutilator> heh
[13:22:52] <awallin> spray on that, make a mask, shine UV on it, was away partly the photoresist, then into KOH ?
[13:22:52] <mutilator> should i have used the work engrave
[13:22:59] <mutilator> word
[13:33:24] <jdh> perhaps. Or posted your pic link again
[13:37:58] <IchGuckLive> i need to close a thunderstorm is hedding here i see flashlights outside
[13:38:03] <IchGuckLive> BY
[13:39:03] <awallin> flash gordon approaching..
[13:39:20] <mutilator> think so eh
[13:48:42] <L84Supper> mutilator, I saw the pic the other day. How fine a resolution do you need? line and space?
[14:10:38] <tjb1> Anyone here have an oil furnace?
[14:11:44] <Jymmm> tjb1: read your memos!
[14:11:50] <tjb1> Memos?
[14:12:14] <Jymmm> tjb1: /msg memoserv help
[14:13:51] <tjb1> Im confused, whats that have to do with an oil furnace?
[14:14:13] <Jymmm> tjb1: not a damn thing, look at the TIME they were sent
[14:14:43] <tjb1> 6:07 pm?
[14:14:49] <jdh> wtf is a memoserv?
[14:15:25] <tjb1> You went to the future?
[14:15:50] <alex_joni> hey Jymmm
[14:16:09] <Jymmm> ho alex_joni
[14:16:38] <tjb1> What are you getting at Jymmm
[14:17:37] <alex_joni> you need a solvent
[14:18:05] <Jymmm> tjb1: you know what, nevermind. forget I said anything.
[14:18:18] <tjb1> Im confused...
[14:18:28] <tjb1> You sent me a memo from the future?
[14:18:46] <Jymmm> tjb1: forget it
[14:19:09] <tjb1> Alright then
[14:19:38] <alex_joni> maybe it was yesterday ?
[14:19:53] <tjb1> MemoServ: - 1 From: Jymmm Sent: Nov 01 18:07:14 2012 [unread]
[14:19:53] <tjb1> [3:00pm] MemoServ: - 2 From: Jymmm Sent: Nov 01 18:08:52 2012 [unread]
[14:20:06] <alex_joni> might be UTC then
[14:20:19] <alex_joni> it's 9pm here atm ;)
[14:22:47] <Jymmm> alex_joni: I thought you were gmt +1 ?
[14:23:33] <tjb1> Jymmm: What time is it there?
[14:27:37] <alex_joni> Jymmm: +2 now, +3 last week (DST)
[14:27:55] <Jymmm> alex_joni: ah
[14:28:04] <Loetmichel> re @ home
[14:28:09] <DJ9DJ> wb Loetmichel
[14:28:20] <mutilator> L84Supper, yea space, doesnt need to be super fine i dont intend to do super detailed stuff
[14:28:27] <jthornton> alex_joni, want to try out my latest time sink?
[14:28:46] <mutilator> i just was looking to anyone with experience for their thoughts
[14:29:42] <jdh> mutilated: I nominated you to buy multiple bits and arrange a study to determine best tool usage.
[14:30:05] <jdh> how about a spring loaded diamond bit?
[14:31:17] <mutilator> if i wanted to do that i wouldnt have asked and just went ahead
[14:31:20] <mutilator> thats what i was trying to avoid
[14:31:30] <jdh> someone has to be the pioneer!
[14:31:47] <mutilator> if it were new frontier i would be
[14:32:13] <L84Supper> mutilator, we used to use diamond bits that worked really well
[14:32:16] <mutilator> once we discover kryptonite i'll be the first to determine how to mill it
[14:32:19] <mutilator> just for you jdh
[14:32:25] <jdh> k00l!
[14:32:48] <L84Supper> mutilator, are you trying to avoid chemical etching?
[14:33:16] <mutilator> yea
[14:33:48] <mutilator> not going to be full production line stuff i just want to be able to do it once in a while
[14:34:07] <andypugh> mutilator: Etching glass normally requires HF. You don't want to.
[14:34:28] <jdh> chemical etching is messy. pcb or glass. cnc rotary etching is such a wonderful idea.
[14:34:35] <mutilator> yea
[14:34:44] <mutilator> well i have plenty of spills from pcb etching
[14:34:50] <mutilator> FeCl doesnt come out of anything
[14:34:56] <jdh> heh
[14:35:05] <andypugh> At least FeCl3 doesn't soak into your skin and dissolve your bones.
[14:35:14] <mutilator> this is true, which is why i chose it
[14:35:41] <andypugh> Rubber mask and grit-blast is one way
[14:36:18] <jdh> we have HF as a byproduct here... we do 'sense and flee' training.
[14:36:32] <L84Supper> mutilator: photopolymer and a DLP to create the mask
[14:37:04] <andypugh> Reprap then grit-blast?
[14:37:51] <L84Supper> or photopolymer applied with a silkscreen
[14:38:00] <L84Supper> then grit blast
[14:39:48] <andypugh> Photopolymer _and_ silkscreen seems a bit excessive
[14:40:22] <L84Supper> cnc cut a steel mask and then blast
[14:40:58] <L84Supper> it depends on if you want a lot of the same pattern or all unique
[14:41:55] <andypugh> Having said that, a spring-loaded Dremel and a diamond bit seems like an experiment worth trying.
[14:42:50] <JesusAlos> Hi
[14:43:09] <JesusAlos> Can emc2 run as two axis machine?
[14:43:36] <andypugh> You mean just XY ?
[14:43:49] <JesusAlos> hi Andy. Yes
[14:45:05] <jdh> http://www.2linc.com/glass_engraving.htm
[14:45:30] <andypugh> JesusAlos: http://axis.unpythonic.net/etchcnc
[14:47:19] <andypugh> You can have a 1 axis machine or a 9 axis machine, or anything in between. LinuxCNC doesn't care
[14:49:54] <alex_joni> jthornton: time sink?
[14:50:54] <jthornton> yea it's been wasting my time all day LOL
[14:51:01] <jthornton> http://gnipsel.com/shop/sfc/sfc.xhtml
[14:51:17] <alex_joni> ha
[14:51:30] <mutilator> lol jdh
[14:51:34] <mutilator> thats the bit i was looking at
[14:51:36] <mutilator> the 120
[14:52:10] <mutilator> http://www.2linc.com/engraving_tools_diamond_tools.htm
[14:52:11] <mutilator> that one
[14:52:22] <alex_joni> jthornton: saw that, looks cool
[14:52:30] <jthornton> thanks
[14:52:36] <alex_joni> but other than functional, I doubt I can offer much insight
[14:52:52] <alex_joni> here's all I did today: http://fbcdn-sphotos-c-a.akamaihd.net/hphotos-ak-snc7/480281_457694610940253_1077615787_n.jpg
[14:53:10] <JesusAlos> eny body know where is the stepconf file of default installation emc?
[14:53:12] <jthornton> looks cool
[14:53:26] <alex_joni> cardboard + scissors.. no cnc ;)
[14:53:59] <alex_joni> for st. martin's day
[14:54:03] <jdh> alex_joni: I'd outsource that to my daughter
[14:56:02] <alex_joni> jdh: my son's 3.. so had to help him out
[14:56:05] <alex_joni> http://ais.badische-zeitung.de/piece/02/3d/c7/70/37603184.jpg
[14:56:18] <alex_joni> or that: http://www.schierling.de/htmls/archiv/archive/archiv2006/images/2006-01-06_rueckblick19.jpg
[14:58:10] <andypugh> JesusAlos: Look in /usr/bin at a guess
[15:03:47] <JesusAlos> the're no are stepconf file
[15:04:25] <JesusAlos> stepconf
[15:07:32] <andypugh> Hang on, do you want the Stepconf program, or the Stepconf.stepconf files?
[15:07:56] <andypugh> The sample configurations don't have stepconf files AFAIK.
[15:09:24] <JesusAlos> ok
[15:10:06] <JesusAlos> i want to modified a default configurations as 2 axis machine
[15:12:22] <andypugh> You need to edit the HAL.
[15:13:18] <andypugh> (It's not difficult, you only need to edit the INI to change COORDINATES and NUM_AXES (or something like that). The extra stuff gets ignored.
[15:13:52] <andypugh> You then need to remove the bits of HAL that refer to joints and axes > 1
[15:23:30] <JesusAlos> I modified AXES=2 and COORDINATES= X Y in .ini file+
[15:24:00] <JesusAlos> but don't know what else change in hal file
[15:24:29] <JesusAlos> if execute change olnly that show error
[15:24:54] <andypugh> Start Linuxcnc from the terminal and delete the lines it complains about one by one...
[15:40:52] <JT-Shop> or start with a lathe config and change Z to Y
[16:35:38] <JesusAlos> can i use Heekscnc with 2 axis?
[16:36:07] <JesusAlos> andypugh: i try it. it run ok
[16:37:00] <andypugh> JesusAlos: I don't know about HeeksCNC. Possibly. dxf-to-gcode is an option, or gcodetools in Inkscape
[16:42:13] <JesusAlos> dxf2gcode is a 3 axis
[16:42:26] <JesusAlos> don't run in a 2 axis machine
[16:43:01] <andypugh> That seems odd, as DXF is 2D.
[16:44:00] <JesusAlos> yes but there are a Z parameters
[16:44:22] <JesusAlos> and when open with emc show error
[16:44:33] <andypugh> It may be possible to configure them away. Or serch-replace them away.
[16:45:03] <JesusAlos> you say edit gcodefile?
[16:45:06] <andypugh> Alternatively, use coordinates=XYZ and simply ignore the Z. That might be the best solution anyway.
[16:45:50] <andypugh> I write most of my G-code by hand, so that's not so scary to me.
[16:47:10] <JesusAlos> iiimagebin
[16:48:34] <JesusAlos> www.imagebin.org/234255
[16:48:49] <JesusAlos> problem
[16:49:02] <JesusAlos> the route cross in to the box
[16:53:57] <andypugh> Hmm, yes.
[16:54:26] <andypugh> What machine is this?
[16:55:10] <andypugh> Hotwire?
[16:55:50] <JesusAlos> :) ofcourse
[16:56:01] <andypugh> I am not sure how to get round that, as there is no easy way for the G-code generator to know which areas are "part" and which are "waste"
[16:56:17] <DJ9DJ> gn8
[16:56:56] <andypugh> You may need to edit the file to make all G0 moves into G1 (as you can't rapid through the material) and modify the paths to miss the actual part.
[16:58:26] <andypugh> I wonder if SheetCAM has a way to define "avoid" areas?
[16:59:00] <andypugh> He says that a post might be free: http://www.sheetcam.com/Features/Posts.shtml
[17:02:17] <JesusAlos> i will try it
[17:04:29] <JesusAlos> how can modifi the file emc open by default mode?
[17:04:44] <JesusAlos> What file contain this information?
[17:04:55] <JesusAlos> i don't see in stepconf file
[17:05:45] <andypugh> http://www.linuxcnc.org/docs/html/config/ini_config.html
[17:16:03] <Jymmm> Got Tree? http://www.youtube.com/watch_popup?v=BFTj0hM3DHM
[17:16:37] <JesusAlos> when execute emc from desktop icon an close. I's all ok
[17:16:55] <JesusAlos> when execute from command
[17:16:59] <JesusAlos> www.imagebin.org/234259
[17:17:07] <JesusAlos> appear some error
[17:17:46] <andypugh> That's wierd
[17:18:24] <andypugh> Is that a VNC window? Because that is a graphics quirk
[17:22:02] <JesusAlos_> :)
[17:22:16] <JesusAlos> :)
[17:22:59] <andypugh> A lot of your other screen-grabs have been Mac windows. I think that might be related to that graphics error.
[17:25:12] <JesusAlos> i will try to see it it's erros was for manual 2 axis configuration
[17:25:56] <JesusAlos> I fall groun sleep. Good night
[17:26:49] <JT-Shop> andypugh: did you look at the thread thing? it has the thread depth now...
[17:40:38] <Aero-Tec> need help
[17:40:47] <Aero-Tec> I have 2 IBM think centers
[17:41:08] <Aero-Tec> one has jitter of11420
[17:41:30] <Aero-Tec> the other over 250,000
[17:41:45] <Aero-Tec> how on earth can that be?
[17:42:13] <Aero-Tec> any help would be great
[17:42:56] <Aero-Tec> BTW the 11420 one was running the gears and update and fire fox and a few other things
[17:43:13] <Aero-Tec> the 250,000 only gears and the test
[17:44:04] <Aero-Tec> that is a huge problem I would think
[17:44:23] <Aero-Tec> I have a 3rd think center I can try
[17:44:57] <andypugh> Different BIOS setups?
[17:45:17] <Aero-Tec> what should I be looing for in the bios?
[17:45:25] <andypugh> JT-Shop: Sorry, repooted and lost the link
[17:45:53] <Aero-Tec> is there some key places to look?
[17:46:51] <Aero-Tec> there is some other things one can do, custom edit of a fire to turn off some things, but will that be near enough
[17:47:04] <Aero-Tec> and why one need the turn off and one does not
[17:47:36] <andypugh> One might have a memory or drive problem.
[17:47:48] <Aero-Tec> is it the INI file I need to look at for the is it SIS or something like that?
[17:48:18] <Aero-Tec> some thing to do with interups
[17:48:53] <Aero-Tec> is there some place to get test software to test the machine?
[17:49:59] <Aero-Tec> that would be cool to have some sort of testing software that would give the computer a complete going over and report problems and if the machine would be good for EMC
[17:50:29] <Aero-Tec> I am new to linux
[17:50:52] <Aero-Tec> so not sure where to go or what to do to get testing software
[17:50:56] <JT-Shop> andypugh: http://gnipsel.com/shop/sfc/sfc.xhtml
[17:51:02] <andypugh> There is probably something, it might even be built in
[17:51:03] <Aero-Tec> or what one would be best
[17:52:05] <Aero-Tec> cool
[17:52:10] <Aero-Tec> app
[17:52:30] <Aero-Tec> so how do I test the computer drives and mem?
[17:52:51] <Aero-Tec> would be good to test the whole thing
[17:54:56] <andypugh> sudo apt-get install memtester
[17:58:58] <Aero-Tec> does it only do mem?
[17:59:35] <Aero-Tec> looking in the web site and found some things to try and to look at
[17:59:42] <andypugh> I guessed a name and googled.
[18:00:37] <Aero-Tec> the thing I was thinking of was not sis but smi
[18:00:55] <Aero-Tec> been awhile
[18:01:10] <Aero-Tec> also I need to change the INI
[18:02:09] <Aero-Tec> can I put my edits into a second file and have it read?
[18:02:13] <andypugh> http://askubuntu.com/questions/109935/are-there-any-hardware-diagnostic-tools
[18:02:18] <Aero-Tec> so 2 INIs that act as one
[18:02:53] <andypugh> Aero-Tec: Yes, you can copy the entire config folder, change the name and change the INI file name and have a complete separate config to break. :-)
[18:03:51] <andypugh> Or, you can indeed have a separate INI in the same folder. Of you look inside sim->axis sample configs you will find that there are 4 or 5 machines all sharing config files.
[18:05:03] <Aero-Tec> cool
[18:05:05] <Aero-Tec> thanks
[18:06:41] <andypugh> Basically the INI defines a "machine" and appears as a choice in the config picker. Any INI can reference as many HAL files as it wants to.
[18:07:44] <JT-Shop> and HAL files can call other HAL files
[18:08:52] <andypugh> can they?
[18:09:13] <JT-Shop> yea, I saw that in a pnccnof config this morining
[18:09:20] <andypugh> scary!
[18:09:44] <andypugh> Ah. "source"?
[18:09:52] <JT-Shop> aye
[18:10:25] <JT-Shop> I had to use grep to find things in his config is was so convoluted
[18:10:53] <andypugh> That's the problem when you let machines do things for you.
[18:13:52] <JT-Shop> I should email you the config so you can have a good laugh
[18:22:13] <Aero-Tec> I need to get back to making chips
[18:22:24] <Aero-Tec> I will try the other spare unit I have
[18:22:55] <Aero-Tec> what is the best way to move the configs to a second computer
[18:24:54] <JT-Shop> usb drive, floppy disk, LAN...
[18:25:33] <Aero-Tec> also seeing as I am doing up a new computer, should I download the any newer versions?
[18:25:47] <Aero-Tec> U figgered usb
[18:25:49] <Aero-Tec> I
[18:26:04] <Aero-Tec> but what dirs should I copy to them
[18:27:01] <Aero-Tec> will have to look and see what version of linux I haverunning
[18:27:32] <JT-Shop> if it is a newer computer use the 10.04 LiveCD
[18:27:48] <JT-Shop> all your configs will go in linuxcnc/configs
[18:28:56] <Aero-Tec> I believe it to be a P4
[18:29:04] <Aero-Tec> is that new enough?
[18:29:41] <JT-Shop> you might be better off with the 8.04 LiveCD
[18:30:05] <JT-Shop> you can still upgrade to the latest version of LinuxCNC after you install by following the instructions
[18:30:46] <Aero-Tec> ok thanks
[18:31:58] <Aero-Tec> could the problem be I am running to new a version?
[18:32:23] <JT-Shop> if your having a problem with Ubuntu yes that could be it
[18:32:30] <Aero-Tec> I think I am running the 10 version on the lathe and that is the one with 250,000 jitter
[18:32:43] <Aero-Tec> no problems that I know of
[18:32:48] <Aero-Tec> other then the jitter
[18:32:58] <Aero-Tec> every thing else is 100%
[18:33:01] <JT-Shop> the key is "that I know of"
[18:33:13] <Aero-Tec> the mill is running 8
[18:33:28] <Aero-Tec> it has 11420 for jitter
[18:33:56] <Aero-Tec> I would like to change the network name of the mill and can no
[18:34:01] <andypugh> Ah, yes, that is almost certainly the difference.
[18:34:19] <Aero-Tec> the lathe was no problem as the gui made it easy
[18:34:32] <andypugh> You may have different drivers with the different systems, for a start.
[18:35:30] <Aero-Tec> so what is the best way to install 8 on the 10 unit?
[18:35:50] <Aero-Tec> will try that first
[18:36:44] <Aero-Tec> it also has windows on it
[18:36:48] <Aero-Tec> win 2000
[18:36:54] <Aero-Tec> for running mach
[18:36:58] <andypugh> You could pretend that you doidn't have a working 8,04 and try all the usual things
[18:37:16] <Aero-Tec> witch is?
[18:37:42] <andypugh> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?TroubleShooting
[18:37:48] <Aero-Tec> I have a working 10
[18:37:56] <Aero-Tec> would like to make it 8
[18:38:10] <Aero-Tec> ok
[18:38:14] <Aero-Tec> was there
[18:38:47] <Aero-Tec> have tried some of it, not all
[18:39:12] <Aero-Tec> I know 8 works so would like to do 8 if possible
[18:39:33] <andypugh> But 10 can work fine too.
[18:39:52] <andypugh> Is it possible you did the SMI fix on the 804 version and forgot on the 10?
[18:40:03] <Aero-Tec> I like 10 better
[18:40:15] <Aero-Tec> could be
[18:40:18] <Aero-Tec> will look
[18:40:30] <andypugh> Is the 8,04 running now?
[18:40:51] <andypugh> lsmod will probably show if rtai_smi is loaded
[18:43:39] <Aero-Tec> they are both running now
[18:43:46] <Aero-Tec> lathe 10 and mill 8
[18:43:50] <andypugh> JT-Shop: Trying to run your Calculator on my Mac I get "RuntimeError: Bad magic number in .pyc file". I don't know if that is to be expected.
[18:44:30] <Aero-Tec> Ismod?
[18:44:38] <Aero-Tec> I am very green
[18:44:56] <Aero-Tec> do I type that into the terminal?
[18:44:57] <cradek> it's incorrect to distribute a pyc. those are not portable.
[18:45:12] <cradek> just delete them
[18:45:16] <Tom_itx> JT-Shop the calc looks better with the scrolling list
[18:45:19] <cradek> they're autogenerated from the py
[18:46:25] <andypugh> There is no .py...
[18:53:54] <JT-Shop> andypugh: I got the same thing trying to run it in windoze
[18:54:18] <JT-Shop> cradek: ok, thanks
[18:57:23] <JT-Shop> andypugh: I've uploaded the py files now
[18:58:00] <JT-Shop> cradek: the pyc files only run on the same operating system?
[19:00:02] <JT-Shop> now to finger out how to get glade on this windoze computer
[19:00:41] <Aero-Tec> mill has smi mod
[19:00:53] <andypugh> aha!
[19:01:09] <Aero-Tec> is there any differances from 8 to 10 in installing the smi mod?
[19:01:28] <Aero-Tec> can I just copy the file over?
[19:01:51] <andypugh> the rtapi.conf? I htink so.
[19:01:58] <Aero-Tec> yes
[19:02:09] <Aero-Tec> any way to know for sure?
[19:02:42] <Aero-Tec> would like to kep
[19:02:57] <Aero-Tec> would like to keep 10 if possible
[19:05:48] <Aero-Tec> The above works for installed emc2 - for 'run in place' it is a bit different.
[19:05:54] <Aero-Tec> what is run it place?
[19:06:04] <Aero-Tec> is that running off the CD?
[19:06:10] <Aero-Tec> live disk
[19:06:16] <andypugh> no
[19:06:26] <andypugh> Compiled in it's own directory.
[19:06:38] <Aero-Tec> do I need to worry about run in place?
[19:06:46] <Aero-Tec> ok
[19:07:00] <Aero-Tec> so seeing as I did a live cd install then I should be OK
[19:07:01] <Aero-Tec> right?
[19:07:13] <andypugh> aye
[19:07:37] <Aero-Tec> off to see if the smi mod works
[19:07:56] <Aero-Tec> the jitter jumps real quick
[19:08:06] <Aero-Tec> seems to be when I open something
[19:08:28] <Aero-Tec> thought the SMI clitch only hit every 64 sec or so
[19:12:35] <andypugh> You only need to edit one file. Why not just do it?
[19:17:17] <Aero-Tec> I did
[19:17:22] <Aero-Tec> and it fixed it
[19:17:26] <Aero-Tec> thanks a mill
[19:17:39] <Aero-Tec> 12044
[19:17:47] <Aero-Tec> not 250K plus
[19:17:51] <andypugh> That's pretty good.
[19:18:08] <Aero-Tec> now I need to fix the ini to set the timeing
[19:18:34] <Aero-Tec> will to a fack ini setup and copy the number over
[19:18:47] <Aero-Tec> unless there is a better way to go
[19:18:52] <andypugh> JT-Shop: It seems to struggle to find a tapping drill for M12x1.75
[19:19:41] <andypugh> I have no idea what you were trying to say there.
[19:20:01] <Aero-Tec> thought for metric taps you just subtracted
[19:20:09] <andypugh> Aye.
[19:20:30] <andypugh> M6x1 = 5. M12x1.75 = 10.25
[19:20:33] <Aero-Tec> should be 10.25
[19:21:02] <andypugh> Probably a 10.2 drill though.
[19:22:10] <Aero-Tec> the hole it drills should be close to 10.25
[19:23:20] <Aero-Tec> so use the wiz and setup a temp comfig and use it to find the numbers for my jitter
[19:23:50] <Aero-Tec> edit the real config to the new numbers
[19:23:56] <Aero-Tec> that is the plan
[19:24:14] <JT-Shop> andypugh: did you check off all the drill types?
[19:24:21] <andypugh> Yes
[19:24:28] <andypugh> Try it...
[19:24:41] <JT-Shop> ok
[19:26:24] <andypugh> I have a special drill box with the correct sizes for M2 to M12 in it.
[19:26:55] <andypugh> M2 x 0.4 6g recommended tapping size 0.35mm for 313% engagement...
[19:26:57] <JT-Shop> for steel or aluminum?
[19:27:10] <JT-Shop> that's tight
[19:28:36] <andypugh> I think your drill picker needs work :-) M3 lists every drill up to 1/16. From 400% to 200% engagment.
[19:28:51] <andypugh> Is it being confused by the inverse pitch of metric?
[19:29:54] <JT-Shop> I did some work on the metric today guess I'm not done yet.. it locked up on me for M12
[19:31:50] <JT-Shop> does it work for < M10 for you?
[19:32:42] <andypugh> It works, but come up with poor dril size choices.
[19:33:35] <JT-Shop> it should show >50% to <100% thread
[19:33:40] <andypugh> It gets M6 OK. Smaller ones get increasingly undersized, and larger ones increasingly oversized.
[19:33:59] <JT-Shop> must be a formula problem then
[19:35:30] <Aero-Tec> now I get joint following error
[19:35:55] <Aero-Tec> whats up with that?
[19:36:02] <Aero-Tec> did not get that before
[19:36:11] <andypugh> That tends to be when the base period is too long. But there are other possible causes.
[19:36:42] <Aero-Tec> that was one of the weird parts
[19:36:53] <Aero-Tec> is was around 24K
[19:37:07] <Aero-Tec> but the new number came out as 100K
[19:37:23] <andypugh> Stepconf does that. (I don't think it should)
[19:37:23] <Aero-Tec> thought that add
[19:37:51] <Aero-Tec> so what should I set it at?
[19:37:54] <andypugh> I probably decided that your peak velocity could be handled at 100k
[19:38:10] <andypugh> 25k maybe?
[19:38:23] <andypugh> 100k is probably fine if you put in the correct max velocity
[19:38:26] <Aero-Tec> so change it to 25K?
[19:38:40] <andypugh> I would.
[19:38:55] <andypugh> I think Stepconf misses the thread granularity issue.
[19:39:10] <Aero-Tec> the wiz said something about the litter being 27K
[19:39:25] <Aero-Tec> but mine was 12.044
[19:39:30] <Aero-Tec> 12044
[19:39:47] <andypugh> What is your step scale? What is your max velocity?
[19:39:48] <Aero-Tec> less then 1/2
[19:40:11] <Aero-Tec> will have to look that up
[19:40:39] <Aero-Tec> guess I will link that dir by net so I can do it from here instead of running all the time
[19:44:26] <Aero-Tec> changed to 25K and that fixed the problem
[19:49:25] <Aero-Tec> it is not allowing me to open the file in my windows computer
[19:49:36] <Aero-Tec> I can see it but not open it
[19:50:20] <Aero-Tec> there should not be anything accesssing that file on the emc computer
[19:50:44] <andypugh> Maybe a share rights problem?
[19:51:04] <Aero-Tec> so it should be available
[19:51:11] <Aero-Tec> how do I change that?
[19:51:13] <andypugh> You aren't logged in as guest are you?
[19:51:27] <Aero-Tec> not on the emc computer
[19:51:36] <Aero-Tec> I am a user
[19:51:42] <Aero-Tec> not guest
[19:51:45] <andypugh> How dod you log into the EMC comp from Windows?
[19:52:04] <Aero-Tec> the windows computer I am not sure what it is telling the emc computer
[19:52:10] <Aero-Tec> no
[19:52:15] <Aero-Tec> shared the dir
[19:52:27] <Aero-Tec> so the win comp can see the emc dir
[19:52:47] <andypugh> I am a Mac guy. Can't help you with Win/Linux issues.
[19:52:53] <Aero-Tec> I did the same with the mill and can play with the files there
[19:53:23] <Aero-Tec> your running emc on a mac?
[19:53:37] <andypugh> No.
[19:54:11] <andypugh> But I sit in front of a Mac most of the time when working on LinuxCNC stuff.
[19:54:25] <Aero-Tec> ok will figger this out and get back to you on what you asked
[19:54:39] <Aero-Tec> right now the X is working good
[19:54:49] <Aero-Tec> the Z is set wrong
[19:54:58] <Aero-Tec> it trips the drive error
[19:55:08] <Aero-Tec> to much acc or speed
[19:55:17] <andypugh> PCW: Getting bored of this Arduino resolver thing now. I am sure it was working previously, now all my channels cross-talk to each other.
[19:55:18] <Aero-Tec> opr both
[19:55:56] <andypugh> Aero-Tec: Check that the stepgen accs are bigger than the axis accs
[19:56:13] <Aero-Tec> ok
[19:56:16] <Aero-Tec> will do
[19:56:22] <andypugh> Hang on. "Drive error" not "Following Error"?
[19:56:30] <Aero-Tec> yes
[19:56:42] <Aero-Tec> the driver is tripping
[19:56:44] <Aero-Tec> not emc
[19:56:51] <andypugh> Stepper drive?
[19:57:00] <andypugh> Or step-servo?
[19:57:05] <Aero-Tec> it was following error till I set the 100K to 25K
[19:57:16] <Aero-Tec> servo
[19:57:23] <Aero-Tec> gecko
[19:57:38] <Aero-Tec> just upgraded to 320X
[19:58:00] <Aero-Tec> so now x works fine
[19:58:12] <andypugh> You probably need to reduce the axis accelleration limits. You can probably leave the stepgen ones where they ae.
[19:58:13] <Aero-Tec> the Z is the one tripping the drive
[19:58:34] <Aero-Tec> I also setup backlash on it
[19:59:18] <Aero-Tec> so did what they said about setting something 2 times faster for the back lash
[19:59:26] <andypugh> I think Mesa should put a couple of all their cards on an eBay shoppe.
[19:59:52] <Aero-Tec> I plan to get some Mesa cards soon
[19:59:54] <Aero-Tec> $$$
[19:59:56] <Aero-Tec> lol
[20:00:32] <andypugh> Aero-Tec: 5i25 + 7i76 is $200 and will make your life so much easier.
[20:01:09] <andypugh> But $200 is $200
[20:01:38] <Aero-Tec> I am in start up mode still
[20:01:43] <Aero-Tec> so buys stock
[20:01:47] <Aero-Tec> tooling
[20:02:11] <Aero-Tec> and fighting with mach and doing this conversion has made things tight
[20:02:35] <Aero-Tec> 7i76, what is it used for?
[20:02:44] <Aero-Tec> I know the 5i25
[20:02:48] <andypugh> It's a BoB
[20:03:01] <Aero-Tec> ok
[20:03:09] <Aero-Tec> so one or 2 of them?
[20:03:17] <andypugh> Well, it is far more than that, but it goes where a BoB would be
[20:03:35] <Aero-Tec> the 5i25 out puts 2 P ports does it not?
[20:04:04] <andypugh> They look like p-ports. They aren't
[20:04:36] <Aero-Tec> so one 7i76 is all I need for the one 5i25?
[20:05:02] <Aero-Tec> what will that give me for IO and what ever else?
[20:05:46] <Aero-Tec> would like to connect spindle control some time soon
[20:06:24] <andypugh> Yes. A 7i76 has 5 (or 6 I forget) places to hook up stepper drives (and can step at MHz) plus 32 inputs and 16 outputs. Plus a VFD potentiometer-emulator
[20:08:27] <andypugh> If you run out of stepper terminals then the rather cheaper 7i78 can connect to the same 5i25 and add another 4 step drives.
[20:08:27] <roh> hm. any place to get those in europe you can recommend?
[20:09:09] <andypugh> roh: Try www.mesanet.eu
[20:09:37] <andypugh> But if you are in .de then I think there is somewhere there too
[20:11:04] <andypugh> Hmm, duzi.cz is not looking great right now
[20:13:11] <andypugh> pcw_home: Is there a Mesa distributor in .de at the moment? There was one that appeared to think it was sound business sense to double the imported-from-the-US price a while ago

[20:15:22] <Aero-Tec> are you talking to me?
[20:15:27] <andypugh> yes
[20:16:01] <Aero-Tec> sorry
[20:16:23] <Aero-Tec> you were asking about the settings
[20:16:36] <Aero-Tec> I finaly got win seeing the files
[20:16:44] <Aero-Tec> well accessing them
[20:17:21] <andypugh> The Z looks more conservative. I wonder if that drive has been configured with a lower current limit?
[20:18:38] <Aero-Tec> the Z has a planetary
[20:18:46] <Aero-Tec> the x does not
[20:19:15] <andypugh> Based on the scales and velocities that shouldn't matter
[20:19:53] <Aero-Tec> how can one tell what one is X and what one is Z?
[20:20:06] <andypugh> 0 is X, 2 is Z
[20:20:20] <andypugh> XYZABCUVW is 012345678
[20:20:58] <Aero-Tec> guess I should set set max to 12
[20:21:00] <Aero-Tec> not 18
[20:21:02] <andypugh> (But that exact correspondence is bad, and due to be removed eventually)
[20:21:53] <Aero-Tec> so for a lathe setup
[20:22:00] <Aero-Tec> does it look good?
[20:22:21] <Aero-Tec> any recommendations?
[20:22:29] <andypugh> It doesn't look glaringly unreasonable.
[20:24:14] <Aero-Tec> the current is set to max
[20:24:25] <Aero-Tec> so that should not be the problem
[20:26:02] <Aero-Tec> max v is units per second
[20:26:10] <Aero-Tec> so inches per second
[20:26:11] <Aero-Tec> right?
[20:27:06] <Aero-Tec> 1 inch per sec is 60 per min, would that be to high?
[20:28:28] <Tom_itx> i get around 80 or so from my mill
[20:28:46] <Aero-Tec> this is a lathe
[20:28:56] <Aero-Tec> the Z has a gear down on it
[20:29:03] <Aero-Tec> for more power
[20:29:14] <Aero-Tec> so speed will suffer
[20:29:48] <Aero-Tec> it is a servo system
[20:32:21] <Aero-Tec> got to be max v that is the problem
[20:32:50] <Aero-Tec> acc witht he gear drive should be able to have great acc
[20:33:12] <Aero-Tec> tima to play
[20:33:45] <Aero-Tec> the funny thing was it was working well
[20:34:00] <Aero-Tec> did all sorts of testing on it and it was good
[20:34:15] <Aero-Tec> not sure why it is now acting up
[20:38:42] <andypugh> step-servos are evil :-)
[20:39:53] <andypugh> There is another way to configure the Gecko servo drive. It is a fair bit of work but might work better (or, alternatively, worse).
[20:40:39] <andypugh> The trick is to treat it as a conventional servo drive, but one that takes a step/dir pulse stream as input.
[20:41:53] <andypugh> You configure the stepgens in velocity-mode, then drive them with a PID in HAL like you would with a servo system. Then the LinuxCNC sends step pulses to correct position errors in the encoder feedback.
[20:42:08] <andypugh> Probably not a real option with a parport system.
[20:44:57] <Nick001> Will LCNC interface directly to gecko stepper drives or what interface card.
[20:46:57] <PCW> andypugh:I think willem whatever his name is runs parallel port stepgen with feedback
[20:49:01] <andypugh> He does all sorts of crazy stuff. :-)
[20:50:06] <andypugh> Nick001: Yes, you can basically plug them directly to the parport.
[20:50:45] <Nick001> and linear scales also?
[20:50:51] <Tom_itx> you'll get better results with a mesa card though
[20:51:26] <andypugh> Probably not. I would imagine that a linear scale would overwhelm a parport
[20:52:01] <andypugh> Nick001: Quadrature scales? What pulse rate?
[20:52:25] <Nick001> which mesa card - ordered one and turns out LCNC didn't support it so I had to cancell it
[20:52:51] <andypugh> Which one did you order?
[20:53:18] <Nick001> says its quad but don't know about pulse rate - tied to stepper speed?
[20:53:54] <andypugh> What resolution is the scale, and how fast will you move?
[20:54:04] <PCW> resolution x velocity
[20:54:06] <Nick001> 7i32?
[20:54:50] <Nick001> about 30ipm - 200 steps/rev
[20:55:05] <andypugh> Ah, yes. it's almost the only card with no LinuxCNC support
[20:55:38] <Nick001> what one will work with 5i20?
[20:55:44] <andypugh> Nick001: 30ipm and what scale resolution?
[20:56:26] <Nick001> not sure of the resolution yet - still have to hook it up and see
[20:59:49] <andypugh> Assuming a 0.0001" scale then 30ipm needs 10kHz sampling, or a 100uS base thread. That might be OK (unless I have my maths wrong)

[21:01:52] <andypugh> Just asked me to endorse her work.
[21:05:20] <Nick001> I'll have to see what base speed the comp is runnig at - I think it stayed at the default setting
[21:22:02] <r00t4rd3d> wtf is the tap extension?
[21:22:26] <jdh> drill file
[21:23:46] <jdh> or some controls gcode files, or probably 10 other things
[21:23:59] <r00t4rd3d> seems to be just gcode
[21:27:38] <andypugh> short for "paper tape g-code"
[21:28:55] <r00t4rd3d> what do you make tap files in ?
[21:29:38] <r00t4rd3d> http://www.cnczone.com/forums/1190261-post2243.html
[21:30:28] <jdh> vectric has a default extension based on post processor
[21:31:01] <r00t4rd3d> oh
[21:31:46] <r00t4rd3d> ahhhhhhh
[21:32:22] <r00t4rd3d> a ton of post processors in aspire have the tap extension :/

[22:55:11] <r00t4rd3d> the bottom one looks like its about to be ripped out.
[22:55:13] <tjb1> Alright, thats just a matter of pulling it out of the pipe monster up there
[22:55:24] <Jymmm> Only because pre-made cbale today just suck for quality anymore.

[23:03:47] <tjb1> Damn…I need them like this month
[23:04:06] <r00t4rd3d> then 3 of them were doa and it took another few months to get the replacements
[23:04:29] <r00t4rd3d> then i lost interest in the what i was doing with them

[23:12:11] <jdh> no. Mine has them by the sawblades
[23:12:24] <toastyde1th> is there a way to find out if they have it even IF you call?
[23:12:38] <toastyde1th> sometimes, they have it and you're there in person and someone is helping you and you may not find it
[23:13:14] <r00t4rd3d> hf sucks balls
[23:13:17] <jdh> they always look it up for me
[23:13:23] <toastyde1th> harbor freight truly is the 30-something's toys r us
[23:13:30] <toastyde1th> nobody knows where anything is and shit is just piled in the isles
[23:13:41] <toastyde1th> it's all crap but you want three of everything in the store anyway
[23:14:55] <r00t4rd3d> ill stop there for glue but thats about it
[23:15:29] <tjb1> ill go up there tuesday and grab 2 of them if I can. I also have Grizzly about 10 miles from school :)
[23:15:46] <r00t4rd3d> a bear?
[23:16:15] <toastyde1th> bears are all around us
[23:16:30] <toastyde1th> they're our family and friends

[23:34:06] <jdh> geez... different wallwart for the monitor fixed it
[23:34:55] <Jymmm> jdh: Yeah, using 100ma when it says 1000ma makes a difference =)
[23:35:23] <jdh> it said 12v, 3 watts
[23:36:11] <jdh> but, yeah... that's what that smell was too :)
[23:36:20] <Jymmm> lol
[23:36:39] <jdh> no idea why I have a 150mA 12v plug here
[23:37:01] <Jymmm> lol, especially when it wants 250ma =)
[23:37:14] <jdh> yep
[23:37:43] <jdh> I need to cut out a box for it.
[23:37:49] <Jymmm> I keep a crapful of em
[23:38:09] <Jymmm> damn expensive now @ ~$15/ea
[23:38:17] <jdh> I have a spline, any idea how to make it a polyline?
[23:38:35] <Jymmm> huh?
[23:38:45] <jdh> in a dxf.
[23:38:50] <Jymmm> oh
[23:40:36] <jdh> heh, save it as an r12 dxf and it converts to polylines... with billions of lines
[23:45:15] <r00t4rd3d> in aspire import it
[23:45:27] <r00t4rd3d> in the modeling tab, bottom left
[23:46:06] <r00t4rd3d> then under Modeling Tools , Import A Component or 3d Model
[23:50:48] <jdh> won't import via model, but does use the spline fine for a toolpath
