[00:05:06] <tjb1> Goodnight all
[01:40:03] <Loetmichel> mornin'
[01:40:14] <Jymmm> ug
[02:20:03] <DJ9DJ> moin
[05:24:26] <r00t4rd3d> http://www.precisebits.com/products/equipment/er16_colletadapter.asp
[05:24:37] <r00t4rd3d> where can i get one of those with a 1/4 inch shank?
[05:25:47] <r00t4rd3d> nvm
[05:25:48] <r00t4rd3d> http://www.amazon.com/Trend-CE-127635-Router-Extension/dp/B001UQ5P3U
[05:26:04] <r00t4rd3d> "collet extension" was what i was looking for.
[05:32:56] <r00t4rd3d> I wonder if anyone uses a air die grinder for a spindle
[05:34:34] <r00t4rd3d> yes i guess would be the answer
[05:35:51] <r00t4rd3d> http://www.cnccookbook.com/img/OthersProjects/SmCNC1.jpg
[10:09:01] <Tom_itx> JT-Shop you around?
[10:09:56] <Tom_itx> i tried setting up my G54 fixture offset and tool length offsets using the tool table and wanted to try and figure out where i'm going wrong.
[10:10:50] <Tom_itx> i know how we did it at the 'big' shop and that's what i did but the length offset on the 2nd tool called up was way off
[10:11:11] <Tom_itx> i tried entering it both as a positive and negative number thinking i screwed that up
[10:12:08] <Tom_itx> i set G54 z zero with the first tool called in the program and set both z offsets to zero
[10:12:19] <Tom_itx> and set the other tools relative to to that
[10:13:42] <jdh> t<n> M6 G43?
[10:14:27] <jdh> or G43 H<n>?
[10:22:39] <JT-Shop> yes in and out
[10:25:42] <Tom_itx> G43 Hx
[10:26:25] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/cnc/cnc_files/enc_hub.txt
[10:26:30] <Tom_itx> there's a sample of my cam output
[10:27:28] <Tom_itx> the offset move is generally called on a z move
[10:29:15] <jdh> does that work?
[10:29:27] <Tom_itx> for the first tool yes
[10:29:42] <Tom_itx> because it's a zero offset
[10:29:46] <Tom_itx> i guess
[10:29:58] <Tom_itx> a 2nd tool would be off by the tool table offset
[10:29:58] <Connor> What does it do 2nd time around ?
[10:30:13] <JT-Shop> Tom_itx, I'm online with a remote PLC making some program changes so it will be about 1/2 hour before I can look
[10:30:22] <Tom_itx> JT-Shop i've got all day
[10:30:26] <Tom_itx> week
[10:30:28] <Tom_itx> month
[10:30:29] <Tom_itx> :D
[10:30:57] <jdh> did your CAM generate this?
[10:31:01] <Tom_itx> if i need to change the cam output format i can
[10:31:02] <Tom_itx> yes
[10:31:36] <Connor> Why not just use the tool table for the offset and be done with it ?
[10:31:41] <Tom_itx> i modded my other sherline one specifically for linuxcnc
[10:31:51] <Tom_itx> Connor that's the issue, i'm trying to
[10:32:02] <Tom_itx> but the offsets are off
[10:32:24] <Connor> I don't think the cam needs to do the H1
[10:32:44] <Tom_itx> it doesn't by default but it's VERY good practice
[10:32:59] <Tom_itx> you can use an alternate H word on a tool if you feel like it
[10:33:01] <jdh> what is the Z for on the G43 line?
[10:33:13] <Tom_itx> move to the z clear height probably
[10:33:23] <Tom_itx> yes
[10:33:45] <Tom_itx> that's what the cam does, hand written it wouldn't need to be there
[10:33:54] <jdh> looks odd between the G43 and the H1
[10:34:06] <Connor> Tom_itx: Did you make sure to RELOAD the tool table after making changes to the tool height ?
[10:34:08] <Tom_itx> that's the format all other machines i've used like
[10:34:17] <Tom_itx> Connor of course
[10:34:28] <Connor> I know. Stupid question.. but.. gotta ask. :)
[10:34:35] <Tom_itx> i've covered my bases
[10:35:00] <Tom_itx> i may have stole one though
[10:35:28] <Tom_itx> fanuc, okuma, tree, fadal all use that format
[10:35:55] <jdh> they use Nnnn too, doesn't make it good :)
[10:36:02] <JT-Shop> G43 does not cause any motion. The next time a compensated axis is moved, that axis’s endpoint is the compensated location.
[10:36:04] <Connor> I was testing from the MDI.. and I never had to do the G43 command for tool offset.
[10:36:15] <Tom_itx> JT-Shop right
[10:36:21] <Tom_itx> should the move be on a separate line?
[10:36:27] <Tom_itx> or does it matter
[10:36:37] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/cnc/cnc_files/enc_hub.txt
[10:36:45] <Tom_itx> JT-Shop ^^ there's a sample output
[10:36:48] <JT-Shop> I would assume a separate line
[10:37:02] <Tom_itx> and it's a rapid move
[10:37:11] <Tom_itx> which shouldn't matter
[10:37:32] <Connor> or maybe I was just calling G43 outright..
[10:37:42] <Connor> I'll have to look on the machine.
[10:37:58] <Tom_itx> or instead of G43 Z-0.9 H1 maybe format it like: G43 H1 Z-0.9
[10:38:03] <Tom_itx> that also shouldn't matter
[10:38:47] <Tom_itx> i plan to leave the H word in as it is just good practice
[10:38:56] <JT-Shop> if you load each tool with Tn M6 G43 then jog to a point does the dro agree with your expectations?
[10:39:07] <Tom_itx> not on the 2nd tool
[10:39:17] <Tom_itx> the first tool called has a zero offset
[10:39:24] <Tom_itx> in one case it was T10
[10:39:41] <Tom_itx> and the G54 z fixture offset is set from that to zero
[10:40:25] <JT-Shop> do you have touch off to fixture or workpiece selected when you touch off Z0 G54?
[10:40:38] <Tom_itx> i use the touchoff dialog
[10:40:47] <Tom_itx> for the fixture
[10:41:00] <Tom_itx> and verify it on the axis display
[10:41:38] <JT-Shop> in the machine menu which one is selected
[10:41:54] <Tom_itx> axis? the z
[10:42:02] <Tom_itx> i've checked for stuff like that
[10:42:28] <Tom_itx> i don't have it up right now to check
[10:43:58] <r00t4rd3d> http://i.imgur.com/P1MGb.jpg
[10:44:02] <r00t4rd3d> Gingerbread Crack House
[10:44:27] <FinboySlick> r00t4rd3d: I'm amused.
[10:45:21] <r00t4rd3d> so was i
[10:50:23] <r00t4rd3d> i just realized the H in hour was silent :/ If you say it with the H it sounds like a arab saying whore.
[10:53:59] <r00t4rd3d> say this with a southern accent and pronounce the H in hour, "You dirty hour"
[10:53:59] <r00t4rd3d> lol
[10:55:10] <Tom_itx> JT-Shop i think i see what you mean
[10:55:37] <Tom_itx> Touch tool off to workpiece vs Touch tool off to fixture
[10:55:42] <Tom_itx> which one should i use?
[10:56:42] <Tom_itx> it should be fixture for using G54..59 offsets shouldn't it?
[10:57:13] <r00t4rd3d> I thought you used that with a touch off plate or something
[10:58:32] <Tom_itx> but i'm not 'touching off'
[10:58:40] <Tom_itx> rather entering an offset value manually
[10:59:45] <r00t4rd3d> im gonna make a touch off plate
[10:59:49] <Tom_itx> i'll try it both ways later on and just see
[10:59:54] <r00t4rd3d> http://www.youtube.com/watch?v=PAeQZ3ux2NY
[11:00:04] <Tom_itx> just read the axis manual on it
[11:03:18] <cradek> use MDI to enter an offset value directly
[11:03:37] <cradek> touch off isn't for that
[11:03:59] <cradek> touch off is for edgefinder-like activity
[11:05:13] <Tom_itx> well i use it for edge finder too
[11:05:29] <Tom_itx> but use the tool tip of the first tool to set G54 z zero
[11:05:48] <cradek> ok that's exactly what touch off is for
[11:05:52] <Tom_itx> the rest are manually entered into the tool table z offset value
[11:06:17] <Tom_itx> measured from the same location as the first tool
[11:06:35] <Tom_itx> it is likely that option in the 'machine' menu
[11:06:39] <Tom_itx> i'll try that later on
[11:14:53] <r00t4rd3d> http://www.ebay.com/itm/CNC-mill-or-router-Tool-Height-setting-Touch-Off-Plate-/330738209759?pt=LH_DefaultDomain_0&hash=item4d018893df
[11:15:03] <r00t4rd3d> i wonder if that would work with lxcnc?
[11:22:24] <TekniQue> r00t4rd3d: I'm confused, which way should face up?
[11:22:37] <TekniQue> that part looks complex for what the job is
[11:25:22] <JT-Shop> Tom_itx, you get your mind right?
[11:26:32] <Tom_itx> not yet but i can't test it right now
[11:28:29] <JT-Shop> ok
[11:29:10] <JT-Shop> Tom_itx, do you have presettable tools ie not R8?
[11:29:16] <Tom_itx> yes
[11:29:21] <Tom_itx> separate collets
[11:29:51] <JT-Shop> so you can take tool out of the spindle then put it back and the Z offset is the same?
[11:30:18] <Tom_itx> yes
[11:30:53] <JT-Shop> ok, if you set the Z0 for all your tools to some common point you can take any tool and set the Z0 for the material
[11:31:35] <Tom_itx> that's basically how i did it
[11:31:59] <Tom_itx> i used the first tool in the program and set it to zero and set the fixture offset to zero from it as well
[11:32:02] <JT-Shop> so for example with Machine > Touch off to fixture selected you set the tool table Z for each tool
[11:32:07] <Tom_itx> then set the others relative to that
[11:32:45] <Tom_itx> it may be better to try it when i'm at the machine
[11:32:52] <Tom_itx> but i'll take note anyway
[11:33:03] <JT-Shop> then with Machine > Touch off to Material selected you take any tool that is loaded with G43 and touch off the Z0 for the material
[11:34:01] <Tom_itx> what difference does that touch to workpiece vs touch to fixture make?
[11:34:05] <JT-Shop> so I load a tool like T1 M6 G43 then jog over to the material and using my trusty 3/8" dowel set the g54 Z offset to 0.375
[11:34:41] <Tom_itx> yeah, i do that too but i offset it in the cad and just enter the value
[11:34:50] <JT-Shop> iirc touch to fixture uses G59.3 or something like that to make sure you don't have any offsets that might get added into your touch off
[11:35:06] <Tom_itx> so i want touch to workpiece selected then right?
[11:35:19] <cradek> this is very carefully described in the docs
[11:35:37] <JT-Shop> :-)
[11:35:37] <Tom_itx> i went over it cradek
[11:35:53] <Tom_itx> but i'm not at the machine to test it right now
[11:35:59] <Tom_itx> i will later today though
[11:36:10] <Tom_itx> got ppl over right now
[11:36:34] <cradek> ... but I can't find it :-/
[11:36:40] <JT-Shop> I made a pyvcp button to touch off to material as I always use the same size dowel to gauge with
[11:36:52] <Tom_itx> cradek i read it already
[11:37:03] <Tom_itx> unless you're gonna show me something else :)
[11:37:24] <cradek> aha
[11:37:25] <cradek> http://www.linuxcnc.org/docs/html/gcode/gcode.html#_g10_l10_set_tool_table_a_id_sec_g10_l10_a
[11:37:31] <JT-Shop> http://linuxcnc.org/docs/html/gui/axis.html#_menu_items
[11:37:33] <cradek> the L10 and L11 sections
[11:38:05] <cradek> but you might not have known that those are exactly G10L10/G10L11
[11:38:24] <JT-Shop> crap I see a borked link
[11:39:57] <Tom_itx> i don't use the G10 to set the offsets
[11:39:59] <Tom_itx> should I?
[11:40:08] <cradek> touch off calls G10
[11:40:10] <Tom_itx> i manually edit the tool table
[11:40:15] <Tom_itx> oh ok
[11:40:25] <cradek> these sections describe the difference between "to workpiece" and "to fixture"
[11:40:53] <Tom_itx> i read over that briefly but don't have time to focus on it right now
[11:41:31] <Tom_itx> JT-Shop you don't worry about chipping a cutter with your touch off button?
[11:41:53] <jthornton> what do you mean Tom_itx ?
[11:42:07] <Tom_itx> <JT-Shop> I made a pyvcp button to touch off to material as I always use the same size dowel to gauge with
[11:42:23] <Tom_itx> don't you use a tool for that?
[11:42:40] <jthornton> the button just does the g code to set the offset
[11:42:45] <Tom_itx> or do you use a dowelpin in a tool fixture
[11:42:49] <Tom_itx> we used to do that
[11:42:58] <Tom_itx> oh ok
[11:43:22] <Tom_itx> i'll fiddle with it later on and see if i can work it out
[11:43:24] <jthornton> I use a dowel on the material for my G54 Z offset and the same dowel on my spindle face for tool table offset
[11:43:38] <Tom_itx> i'm not sure where the workpiece vs offset was set in the menu
[11:43:57] <Tom_itx> gtg right now
[11:44:03] <jthornton> ok
[12:16:18] <Connor> jdh: Got the air cylinder in today! :)
[12:16:42] <jdh> cool.
[12:17:23] <jdh> I have port plugs if you need them. You need to leave a 2nd stage on, or put an OPV in its place.
[12:17:36] <jdh> how are you planning on getting the tanks filled?
[12:17:48] <Connor> I'm certified.
[12:17:58] <jdh> I meant hydro/vip
[12:18:18] <Connor> Oh. I'll have to have them hydro'd probably.. they both are still full though.
[12:18:36] <Connor> 2000psi in the one I was using to test with last night.
[12:18:39] <jdh> steel or aluminum?
[12:18:50] <Connor> steel. So, they were only filled to 2200
[12:19:42] <jdh> I have a couple of steel 72's I use for oxygen for deep caves
[12:19:58] <ReadError> i think i have some good gcode for PCB milling :)
[12:20:29] <jdh> ReadError: do you have good bits, good spindle runout, good tram?
[12:22:35] <ReadError> http://www.precisebits.com/products/carbidebits/scoreengrave.asp
[12:22:51] <ReadError> EM2E8-0625-90VC 90° "V" point, ZrN coated PreciseBIT 2-flute Scoring / Engraving bit, 0.005in tip web,1.42 in. (36mm) OAL
[12:23:08] <Connor> jdh: Yea, I'll need 1 plug.. and if you found a OPV that would be cool.
[12:23:29] <jdh> I think I saw one last night
[12:24:06] <Connor> Cool.. and those valves I found last night won't work.. I need valve that has 3 ports. 1 supply, 1 feed and 1 vent.
[12:24:14] <Connor> but, I need 2 of those..
[12:24:31] <jdh> whyk 2
[12:24:43] <Connor> One for extend, 1 for retract.
[12:25:19] <jdh> using belleville washers?
[12:25:37] <Connor> Probably could get away without it..
[12:26:02] <jdh> if you need 1500psi of force to hit it, you won't need any to self-return
[12:26:03] <Connor> but.. I think you need the retract to make sure the piston isn't touching the spindle.
[12:26:31] <Connor> so, without full retract, it'll be touching the top of the draw bar.
[12:27:03] <jdh> oh, that might be needed. Can you use the quill at all with that?
[12:27:05] <Connor> not to mention since it's a floating setup.. it might cause it to not drop back down.
[12:27:25] <Connor> I will have a plate that I can remove that allows me to use the quill.
[12:27:41] <Connor> the plate that goes under the washers..
[12:28:08] <jdh> you should be able to get a double solenoid that goes both ways
[12:28:27] <Connor> You can, but then the cylinder will have continues pressure on it all the time.
[12:28:32] <Connor> which I don't want.
[12:28:49] <jdh> then it won't stay retracted
[12:28:56] <Connor> Yea it will.
[12:29:03] <Connor> friction
[12:29:13] <Connor> it's hard to move manully.
[12:29:40] <jdh> it will be harder to move with lines plugged
[12:29:46] <andypugh> Use a spring
[12:29:58] <andypugh> (I have a spring)
[12:30:39] <Connor> would save on the air tank.. by 1/4th.
[12:30:45] <Connor> per tool change.
[12:30:55] <andypugh> It just occurred to me that it might be possible to devise a drawbar mechanism where the head just rams itself into a soild pusher.
[12:30:59] <Connor> 3 stages to extend... 1 stage to retract.
[12:31:27] <andypugh> (Not in my case, I have a knee-mill)
[12:32:29] <Connor> andypugh: I don't want the stress on the spindle.
[12:32:38] <Connor> time for lunch.. back in a fw.
[12:33:44] <andypugh> I need a 5 or 6 pin oiltight connector. ie, I need the panel-mount socket to not let oil leak through it. I know that Lemo meet that requirement, but not the requirement that I be prepared to pay the cost.
[12:34:31] <archivist> andypugh, after a fight I got into the hobbing machine, its cut is cam driven and currently is set at .26", needs some modification
[12:34:33] <andypugh> The DIN socket I bought (IP68 version) actually allows daylight through round the pins, so fails.
[12:35:26] <archivist> you want a mil spec connector, sometimes available second hand
[12:35:36] <andypugh> Bizarrely the cheapest source of Lemo connectors by far is in San Francisco. Including postage.
[12:35:51] <archivist> I have a few
[12:35:54] <jdh> if you don't need much current, here are IP67 RJ45s relatively cheap
[12:36:01] <jdh> s/here/there/
[12:36:11] <andypugh> IP rating is not the same thing.
[12:38:10] <andypugh> So, it would be a bit of a gamble.
[12:40:13] <archivist> I have seen seals put behind panel connectors so that the connector ends up in its own compartment
[12:40:39] <Jymmm> andypugh: Huh? what do you mean IP rating isn't the same? Only thing higher is IP68 which is meant for continous submersion
[12:41:08] <andypugh> IP rating describes the accessibility to fluids of the contacts.
[12:41:52] <archivist> from where though
[12:41:55] <andypugh> The conector I just put in the bag to return to RS was IP68, but you can see daylight through the socket round the pins.
[12:42:59] <Jymmm> andypugh: Ok, so it's rated as when plugged in.
[12:43:03] <andypugh> So, in my application I could guarantee that none of the gearbox oil would leak out of the connector, but the conector itself would fill up, and oil would seep back down the cable.
[12:43:43] <archivist> the connector is not usually your case seal put a gland and back box behind the connector
[12:43:53] <andypugh> The application is to connect to an encoder inside my milling spindle. (not optical, obviously)
[12:44:20] <JT-Shop> mil spec connectors are oil tight
[12:45:59] <archivist> the plug 150842439281
[12:46:54] <JT-Shop> andypugh, could you just pass a cable through an oil tight cable grip?
[12:47:46] <andypugh> JT-Shop: I could. But the head is demountable to use the horizontal spindle or slotting head
[12:48:21] <JT-Shop> you could have a male/female connection outside?
[12:50:09] <archivist> I have also seen the rear of a connector given a dose of sealant/glue for the same purpose
[12:52:46] <Jymmm> Just wrap only old connector with an old innertube and some rubber cement
[12:52:58] <Jymmm> s/only/any/
[12:53:45] <andypugh> I do _like_ lemo connectors
[12:55:20] <archivist> does this mean Im supposed to post some used ex equipment lemo, cant remember the pin counts at the moment
[12:55:31] <jdh> I have hundreds of lemo's here, but all for rg174
[12:56:09] <andypugh> I have some 1B size in my desk drawer at work.
[12:56:26] <archivist> these are three pin
[12:56:28] <andypugh> I would prefer the 0B size, though.
[12:57:25] <Jymmm> I wasn't kidding... http://www.walgreens.com/store/c/mighty-fixit-flexible-silicone-wrap-tape/ID=prod6044187-product
[12:58:03] <andypugh> I can imagine that reacting with the oil over time.
[12:58:53] <JT-Shop> what's a lemo?
[12:58:54] <Jymmm> http://www.buy.com/prod/henkel-04200-3-4-x22-rubber-electric-tape/204616234.html
[12:59:21] <andypugh> There is no rush. I can just hang around the skip at work and wait until they throw out a batch of ECUs, those always have Lemo connectors
[13:00:06] <andypugh> JT-Shop: http://en.wikipedia.org/wiki/LEMO
[13:00:49] <archivist> the sockets on these 3 way have no way to seal the outer in the chassis, came out of paxolin panels
[13:01:39] <JT-Shop> cool
[13:01:44] <JT-Shop> never seen one before
[13:01:51] <andypugh> They are connectors that push in then lock with barbs that retract when you pull them out by the sleeve (but not if you pull the cable). Very nicely made. Even the cable-grips are a work of art: http://www.ebay.co.uk/itm/261028996171
[13:02:10] <jdh> I have all of those in the pic in my drawer. (for NIM & CAMAC modules)
[13:03:55] <andypugh> The 00 size are very cute but fiddly to solder (4 pins, 7mm OD)
[13:16:10] <tjb1> Nothing like being on hold for a half hour to talk to someone...
[13:16:26] <jdh> cable company?
[13:16:53] <tjb1> School...
[13:18:43] <tjb1> Times like this I think all the money they get from me could afford another few people working in this office
[13:28:37] <tjb1> Derrrr…what do you mean your loan didnt increase
[13:30:50] <JT-Shop> yea, you don't own your property around here you just rent it from the school board
[13:33:02] <tjb1> Now I have been on hold for 5 minutes for the woman to find out why it didnt increase
[13:35:16] <tjb1> Why the hell does it matter to the school what I set my loan at?
[13:35:26] <tjb1> Didnt know they were paying it for me
[13:45:20] <tjb1> Pretty funny how a 3 credit class that is costing me almost $1500 meets 1 time a week for 45 minutes
[13:45:47] <Connor> What's the class for ?
[13:45:55] <archivist> they like to make a profit
[13:45:59] <tjb1> Compared to other 3 credit classes that meet for 5 hours a week
[13:46:11] <tjb1> Its Senior Seminar - Lab
[13:46:26] <tjb1> "Individualized learning experience in which the student, working under a faculty mentor, completes and delivers the finished project as outlined during the lecture, planning portion of the senior seminar experience (MET 495). Successful completion of the project requires a finished project, including executive summary, an evaluation process, and a verbal presentation. 3 Credits (0 Lecture - 9 Lab) Prerequisite(s): MET495. Spring Only."
[13:46:54] <tjb1> Ive been told by a lot of people you dont even show up to half the classes...
[13:47:03] <Jymmm> Funny how people pay $20,000 USD for a single sheet of 8"x11" paper - gotta love marketing!
[13:47:24] <tjb1> $20k?
[13:47:26] <jdh> $20k?
[13:47:27] <tjb1> Hahaha
[13:47:33] <Jymmm> 20K+
[13:47:39] <tjb1> More like 90k
[13:47:40] <jdh> x4
[13:47:45] <Connor> $20k is a bargin.
[13:47:47] <r00t4rd3d> if it was blotter paper.......
[13:47:48] <tjb1> It cost me over 20k a year
[13:48:16] <r00t4rd3d> and perforated
[13:48:47] <tjb1> You dont get your diploma at graduation
[13:48:50] <tjb1> They mail it to you
[13:48:59] <jdh> I got my last one at graduation
[13:49:00] <r00t4rd3d> I got my GED in jail
[13:49:04] <r00t4rd3d> for free
[13:49:23] <jdh> that's the way to work the system!
[13:49:24] <r00t4rd3d> I make 7-800 bucks a week
[13:49:25] <tjb1> They said they dont have enough time to print the diplomas between grades being released and graduation
[13:49:27] <Jymmm> r00t4rd3d: When do you get release?
[13:49:33] <Jymmm> d
[13:49:39] <r00t4rd3d> 13 years ago
[13:49:50] <r00t4rd3d> i did a year for dwi
[13:49:56] <jdh> for just one?
[13:50:06] <jdh> a year here would take 3 or more
[13:50:06] <r00t4rd3d> nah 2nd
[13:50:18] <r00t4rd3d> i got 2 in 10 years
[13:50:25] <r00t4rd3d> they do extra punishment for that
[13:50:30] <Red70sShow> r00t4rd3d: <---- dumbass
[13:50:31] <jdh> did your year rehabilitate you?
[13:50:40] <r00t4rd3d> i got another one so i guess not
[13:50:54] <jdh> what he said.
[13:51:13] <r00t4rd3d> then one day i just stopped drinking

[13:53:18] <tjb1> Nah, I had to take 2 of them jdh
[13:53:51] <jdh> my son went to freshman orientation yesterday and got his first schedule... and the bill.
[13:54:04] <r00t4rd3d> you mean you got the bill
[13:54:11] <tjb1> I love the first schedule, they put you into a bunch of crap
[13:54:14] <jdh> oh yeah
[13:55:03] <tjb1> Make sure your kids study like hell for the placement test, they screw that up and they will be spending 6k on useless classes just to start taking required classes
[13:55:44] <jdh> he has 23 hours of AP credits
[13:56:20] <tjb1> I got advanced placed because of votech but that almost screwed me in the placement test
[13:56:42] <tjb1> I didnt get nearly enough or good enough math in highschool

[14:12:32] <DJ9DJ> harhar :) good one :)
[14:19:13] <MrSunshine> hmm, using a multimeter my pwm to analog circuit gives out 1V at M3 S1 ... hmmm
[14:19:27] <MrSunshine> gonna hook it up on an oscilloscope to see what happends, according to simulations it should work :p
[14:27:49] <gene77> Hi Guys, got nuther problem. I am out of spindle fuses for my lathe, and I need an electronic auto stop if the spindle error term gets too big.
[14:28:07] <gene77> But I haven't a clue how to go about that...
[14:28:13] <MrSunshine> humm ?
[14:28:16] <MrSunshine> you burning fuses? :)
[14:28:38] <MrSunshine> and what do you mean with "spindle error term gets to big" ?
[14:28:47] <jdh> pid controlled spindle?
[14:30:01] <gene77> Yup, ATM I have a way too big boring bar mounted, and there is just enough flexibility in the mount that its bending over and digging into the work, yes, pid controiled spindle
[14:30:17] <gene77> s/ controilled
[14:30:27] <gene77> s/ controlled
[14:33:14] <andypugh> The PID component has an error output. Pass that to a "comp" HAL component (that's the compare function, not the compiler) and send the output to the soft-estop
[14:36:23] <tjb1> Thats cool, my school office just pulled me out of a class
[14:36:46] <gene77> Lemme see how that looks. Thanks Andy
[14:37:35] <gene77> Thats a setp, can I use an arbitratry name there?
[14:39:17] <tjb1> Oh that class was cancelled because we didnt get enough students...
[14:39:26] <tjb1> Cool, now I am at 10 credits and a part time student
[14:42:30] <andypugh> gene77: I don't understand the question
[14:44:53] <gene77> first, where in the html docs for 2.5, is the manpage for comp, the comparator?
[14:46:48] <gene77> AKA the loadrt syntax for one copoy of it.
[14:47:23] <tjb1> Ah lovely, picking from classes that the whole school already scheduled
[14:48:01] <jdh> womens studies
[14:48:50] <gene77> Andy, I am trying to detect a stalled spindle fast enough to save the fuse.
[14:49:21] <tjb1> Boy the school really fucked me over now
[14:49:34] <jdh> what school is this?
[14:49:51] <gene77> So far I have "loadrt comp count=1" and "addf comp servo-thread:
[14:50:28] <tjb1> pct.edu
[14:51:23] <gene77> So next I need to take "pid.0.error" to one of the comp.0.input's I assume.
[14:52:07] <andypugh> Yes, net pid error to one input, ans setp the other to a suitable threshold
[14:52:25] <andypugh> (You will need to check the manpage to figure out which input it which)
[14:52:36] <tjb1> Looks like I am taking Native American History and Culture :/
[14:52:53] <andypugh> Actually, wcomp might be better if the error is bipolar.
[14:54:26] <gene77> And thats the manpage I can't find on line
[14:56:51] <tjb1> Hey jdh, tell your son about www.ratemyprofessors.com
[14:57:16] <gene77> It could be bipolar I suppose, but so far I only can drive it normally
[14:59:18] <gene77> Hummmm, comp not found, so addf failed. Did I spell it right?
[15:00:36] <jdh> http://www.linuxcnc.org/docs/html/man/man9/comp.9.html
[15:00:39] <jdh> that manpage?
[15:02:44] <gene77> yup, thats it. but loadrt can't find comp or wcomp. WTH?
[15:03:05] <gene77> Thanks jdh
[15:03:46] <gene77> Are those pieces in the /usr/share/linuxcnc tree?
[15:07:34] <gene77> if thats where they are supposed to be, they are all missing, so obviously that isn't the right path..
[15:09:04] <anonimas1> gene77: the best way is to run it off a cfd with a torque limit set and a error output
[15:09:17] <anonimas1> vfd..
[15:09:51] <anonimas1> nvm..
[15:09:53] <anonimas1> pid works too.
[15:12:06] <gene77> maybe, but I have a C41 and the OEM motor controller, call me cheap, its a mini-lathe
[15:12:35] <jdh> cheap
[15:12:45] <jdh> I kept blowing fuses in my 7x also
[15:13:45] <gene77> And in order to get fast enough, I will probably have to swap out that 10uf in the output opamp of the C41 for a .1 mylar, the thing is a dawg.
[15:14:51] <jdh> I have a c41, the response is incredibly slow.
[15:18:10] <gene77> change out both of those 10UF caps in it for .1 mylar's. The other one controls the reversing relay. To slow there will clear fuses by the wagonload
[15:18:34] <jdh> do you have the new one or old one?
[15:19:55] <gene77> The OEM controller went up in smoke, so its fresh, the C41 is about 3 months old.
[15:20:14] <jdh> does it have a 7805 in one corner?
[15:20:29] <gene77> I believe so.
[15:20:39] <jdh> that's the old one
[15:20:46] <jdh> new one is 5V only
[15:24:13] <gene77> Oh? That ought to run a bunch cooler then, as I have a 12 volt ac wall wart in one corner of the box.
[15:25:15] <gene77> To be Truthful, I was a dumbass for not just buying another PMDX-106. Complex to hook up but the Just Work(TM)
[15:26:52] <jdh> I've never really checked, but I feel like mine has a 1-2second response at a minimum
[15:34:56] <gene77> Its not quite that slow, but its sure slow enough to effect how much pid you can use.
[15:35:28] <gene77> Now, can someone tell me why I can't loadrt comp or wcomp?
[15:36:18] <JT-Shop> comp is a program that makes a component
[15:37:08] <JT-Shop> gene77, what is your loadrt line and addf line for wcomp
[15:37:16] <andypugh> JT-Shop: comp is also (confusingly) a HAL component
[15:37:26] <JT-Shop> really
[15:37:43] <JT-Shop> yep th4re it is
[15:41:02] <r00t4rd3d> http://www.mediafire.com/?a7o2m9odjnfzk72
[15:41:14] <r00t4rd3d> if you have a yahoo account, you might want to check that list
[15:42:57] <r00t4rd3d> 450,000 yahoo usernames/passwords
[15:43:41] <JT-Shop> andypugh, axis sim loads 3 copies of comp but does not add them to a function that I can see
[15:43:49] <r00t4rd3d> wait 739,853 accounts
[15:43:53] <JT-Shop> I geuss gene77 will come back
[15:45:37] <r00t4rd3d> i see gmail, msn, hotmail, aol, att, and a lot of others in there too
[15:47:15] <r00t4rd3d> http://www.cnn.com/2012/07/12/tech/web/yahoo-users-hacked/index.html?hpt=hp_t1
[15:47:27] <andypugh> Does sim add anything to a thread?
[15:47:28] <gene77> I never left, and we aren't building a module, comp is a 2 input comparator, with hysteresis. It ought to be loadable with "loadrt comp count=1
[15:48:14] <gene77> But I just found my soldering iron has been blowed up again, it now has a hot tip, about 40 volts ac hot.
[15:48:34] <r00t4rd3d> if anyone wants me to check the list for your yahoo email , post it
[15:48:35] <MrSunshine> lol disregard everything ive said
[15:48:37] <MrSunshine> when setting speed1: 0 PWM: 0 and speed2: 2000 PWM: 1 i got a value all the way down
[15:50:46] <gene77> So I guess I'm outta here for a bit, while I go buy another $140 version of it, this is only the 4th time a hot circuit that shouldn't be has blown it. :(
[15:52:00] <uw> unrelated topic, but has anyone ever use naval jelly with success?
[15:52:03] <uw> never seems to work for me
[15:52:13] <jdh> uw: me either
[15:52:15] <uw> and if it does, just barely
[15:52:30] <jdh> yep
[15:52:41] <uw> hmm, so im not alone
[15:52:46] <jdh> turns it lightly black, but that scrapes off
[15:52:51] <uw> thats, reassuring
[15:53:06] <uw> yea i still see rust
[15:53:28] <uw> it says it's supposed to "convert" the rust to some phospous or whatever
[15:53:44] <jdh> iron phosphate
[15:53:56] <uw> ah thats it
[15:54:09] <uw> so, what are your methods for removing rust?
[15:54:13] <uw> if you have any?
[15:54:35] <jdh> mechanical removal
[15:55:07] <uw> but what about the hard to get areas? where even a sand blaster cant get?
[15:57:19] <jdh> I have used other phosphoric acid based things that worked better than naval jelly, but they still just did the surface of the rust.
[15:58:05] <JT-Shop> gene77, yep loadrt comp count=1 <note no spaces iirc between count the = and 1
[15:58:37] <JT-Shop> gene77, and comp needs a floating point thread
[15:58:37] <uw> i see. welp, out to try something else.
[16:01:32] <JT-Shop> soak it in a strong solution of caustic soda to remove the iron oxide down to the steel
[16:01:56] <JT-Shop> note that caustic soda is not for the careless types
[16:02:24] <jdh> like old fashioned drano?
[16:02:35] <jdh> or something stronger?

[16:11:27] <ReadError> but none disconnected i can see
[16:12:21] <anonimas1> jdh: probably draino is caustic soda.. naoh..
[16:19:30] <Jymmm> and you still have to neutralize the acid afterwards.
[16:21:39] <JT-Shop> jdh, I used dry caustic soda and note you don't add water to caustic soda you add caustic soda to water
[16:21:48] <DJ9DJ> gn8
[16:21:54] <Jymmm> JT-Shop: heh
[16:22:02] <JT-Shop> and like Jymmm said you must neutralize after

[16:48:31] <gene77> I just ordered the whole rework station this time, $150 w/ship.
[16:48:33] <JT-Shop> gene77, if you comment out the addf does it load?
[16:49:11] <gene77> I doubt it, that stuff is all in normal order, with the loadrt above it in the hal file
[16:49:37] <Jymmm> JT-Shop: could you link me to a photo of the "check valves" you were taking about?
[16:50:31] <r00t4rd3d> jymm are you near kingston ontario?
[16:50:53] <Jymmm> r00t4rd3d: If you consider 3000 miles 'near', sure.
[16:51:10] <JT-Shop> Jymmm, any spring loaded check valve would do I assume depending on the viscosity
[16:51:12] <Jymmm> r00t4rd3d: you are in Kingston?
[16:51:18] <r00t4rd3d> no but close
[16:51:31] <Jymmm> r00t4rd3d: what city/town?
[16:51:37] <r00t4rd3d> 45 min or so from the boarder which is about 20 minutes away

[16:51:50] <r00t4rd3d> upstate ny
[16:51:51] <JT-Shop> gene77, do you know if the addf or the loadrt line is the problem?
[16:51:53] <Jymmm> oh
[16:52:04] <gene77> Humm, if I comment out the addf, the next error is no "soft-estop" pin.
[16:52:22] <gene77> no mention of the loadrt rfailing?
[16:52:28] <gene77> no mention of the loadrt failing?

[16:53:06] <ReadError> see the board i just made?
[16:53:44] <JT-Shop> Jymmm, any with the correct thread size will be fine depending on the viscosity of the fluid pumped
[16:53:46] <r00t4rd3d> no
[16:53:54] <andypugh> There is no soft-estop pin. That was me being too lazy to look up the real name. motion.estop-in or something

[16:54:27] <ReadError> one of the traces is super small

[16:54:35] <JT-Shop> gene77, is your servo thread a floating point thread?
[16:55:06] <gene77> it should be, its the slow one

[16:55:51] <r00t4rd3d> did you check all your traces?

[16:59:05] <JT-Shop> some are some are not
[16:59:05] <gene77> You may have hit it, I didn't have an .0 appended to the addf line.
[16:59:39] <andypugh> The reason I am good at spotting errors is that I make them all myself, repeatedly.

[17:04:15] <Tom_itx> just plug it in and the shorts will find themselves
[17:04:46] <ReadError> Tom_itx: i thought it was set to where it modified the depth based on continuity
[17:05:01] <Tom_itx> i dunno about that

[17:31:28] <r00t4rd3d> a new cnc parts ebayer
[17:37:19] <r00t4rd3d> are the shafts in steppers replaceable?
[17:37:47] <Tom_itx> probably not by end users
[17:42:10] <andypugh> r00t4rd3d: I think you can ruin the stepper by taking the rotor out, so that's the first problem.
[17:45:28] <r00t4rd3d> http://www.youtube.com/watch?v=5thxBgew7N0&feature=player_detailpage#t=300s
[17:45:46] <r00t4rd3d> the place i got my motor and the same motor i have and the guy taking it apart
[17:47:43] <Tom_itx> go for it
[17:47:47] <Tom_itx> they're cheap
[17:48:38] <r00t4rd3d> i will email the manufacture and see if they can tell me where to get a shaft
[17:49:17] <r00t4rd3d> i could probably get my shaft welded
[17:49:37] <Tom_itx> if it's double ended i'd turn it around
[17:49:42] <djdelorie> "dear manufacturer, please give me the shaft..."
[17:49:48] <Tom_itx> haha
[17:50:02] <r00t4rd3d> and only the shaft
[17:50:21] <Tom_itx> it is pressed in
[17:50:33] <Tom_itx> and you would screw up the rotor when you replaced it
[17:52:12] <andypugh> I bit of silver-steel would work. (I think you guys call it drill rod)
[17:52:39] <andypugh> It might even be a plain unmachined length
[17:52:44] <Tom_itx> yeah, i can get water or oil hardened drill rod
[17:53:33] <r00t4rd3d> it comes right out, watch the vid
[17:53:36] <r00t4rd3d> http://www.youtube.com/watch?v=5thxBgew7N0&feature=player_detailpage#t=300s
[17:53:46] <r00t4rd3d> there is 3 gears pressed on it
[17:53:51] <r00t4rd3d> and there is a fatter part
[17:53:59] <andypugh> Those are not gears, they are magnets
[17:54:01] <r00t4rd3d> 2 gears pressed on
[17:54:13] <andypugh> And there are sometimes 3
[17:54:13] <ReadError> r00t4rd3d: cut anything cool before it broke?
[17:54:25] <r00t4rd3d> not really
[17:54:38] <r00t4rd3d> i was doing a Family Guy family portrait when it snapped
[17:54:46] <ReadError> awww
[17:54:52] <ReadError> how far in did you get?
[17:55:01] <r00t4rd3d> far enough to piss me off
[17:55:10] <andypugh> I have taken steppers apart. But I have read that when you take the magnets out, they become partly demagnetised. The stator acts as a magnetic "keeper"
[17:55:11] <ReadError> you think the acceleration is too high?
[17:55:21] <r00t4rd3d> i dont know
[17:55:32] <r00t4rd3d> i just upped it from 0.2 to 0.3
[17:55:48] <r00t4rd3d> so i will turn it back down
[17:55:53] <ReadError> inch or m/s^s ?
[17:55:58] <r00t4rd3d> inch
[17:56:09] <andypugh> The shaft broke because the shafts were not properly aligned and it was a rigid coupling.
[17:56:18] <r00t4rd3d> i think it was the non-flexable coupler i was using
[17:56:37] <ReadError> got any pics of the portrait ?
[17:56:48] <r00t4rd3d> lol no but i can take one
[17:56:51] <r00t4rd3d> brb
[17:56:55] <andypugh> It's a lovely annular fatigue failure.
[17:57:10] <andypugh> (I used to look at cracks for a living)
[17:58:15] <Tom_itx> i'll just leave that one alone

[18:02:47] <tjb1> You got the coupler?
[18:03:04] <tjb1> It rained today for the first time in a couple weeks
[18:03:20] <andypugh> Apart from anything else, it looks like I would end up trampling snails on the path, and I hate that.
[18:03:27] <r00t4rd3d> i ordered it

[18:11:45] <r00t4rd3d> tjb1^
[18:11:47] <tjb1> Those spring ones?

[18:12:02] <r00t4rd3d> that
[18:12:10] <tjb1> Wonder if you could mount the stepper on like rubber standoffs?
[18:12:14] <Tom_itx> what does tool diameter cutter comp do on a straight plunge cut?
[18:12:26] <r00t4rd3d> cuts the outside of the line
[18:12:31] <Tom_itx> probably nothing
[18:12:33] <r00t4rd3d> oh wait
[18:12:51] <tjb1> andypugh: http://www.ebay.com/itm/Parallel-Port-Breakout-Board-for-CNC-and-Robot-Control-/150855791346?pt=BI_Robotics&hash=item231fb4b2f2#ht_1994wt_1398
[18:13:45] <r00t4rd3d> http://dumpstercnc.com/images/acme_coupler_01.jpg
[18:13:53] <r00t4rd3d> that is the couple i had on when broken happen
[18:14:08] <r00t4rd3d> one end is threaded for threaded rod
[18:14:56] <r00t4rd3d> they probably would work fine on a aluminum frame setup
[18:14:59] <r00t4rd3d> but not wood
[18:15:04] <cradek> Tom_itx: the moves before and after the plunge(s) determine the location of the corner
[18:15:07] <andypugh> tjb1: Do you just want it to make wiring easier, or do you have other requirements?
[18:15:17] <tjb1> I need more I/O than a G540 offers
[18:15:47] <Tom_itx> cradek i'm using it just to 'drill' a hole because i'm using the same size mill cutter required
[18:15:54] <Tom_itx> center cutting endmill
[18:16:39] <tjb1> Just a Z axis move
[18:16:43] <Tom_itx> just a linear z move
[18:17:00] <tjb1> You would have to activate it with a G4x anyway
[18:17:16] <tjb1> What is it…40, 41, 42?
[18:17:25] <andypugh> tjb1: So, you are adding a second parport?
[18:17:31] <tjb1> Yes andypugh
[18:17:32] <cradek> no matter what you're doing, my answer is correct, beware if the answer seems strange because that means you're using cutter comp strangely
[18:18:11] <cradek> I can't see how using cutter comp for drilling makes much sense
[18:18:22] <Tom_itx> cradek it's not that i'm using it strangely as i need it on the rest of the part however i wanted to know the effect it would have on the z moves
[18:18:24] <cradek> you could drill inside the corners of a square I guess
[18:18:33] <tjb1> cradek: if cutter comp was activated when moving with a G01 command it would offset whichever direction correct?
[18:18:41] <andypugh> I don't see how it makes _any_ sense
[18:18:48] <Tom_itx> it's not supposed to
[18:19:17] <Tom_itx> i know it offsets the cutter based on the comp but does it affect linear z moves?
[18:19:32] <tjb1> No but it will affect the position
[18:19:52] <Tom_itx> i'm cutting some profiles then i was drilling a couple holes with the mill since they are the same size
[18:19:54] <tjb1> Just shut it off before moving there
[18:20:18] <cradek> again: the position is determined by the corner made by the moves before and after the Z-only moves
[18:21:10] <andypugh> tjb1: I know you have gone down the parport route now, and you probably only need a couple more IO lines, but for $70 you could have had a Mesa 5i25 to hook up to the G540, then the second header of that can connect a further 384 IO pins.
[18:21:28] <tjb1> Wow, 384
[18:21:39] <Tom_itx> tjb1, i'd sure go that route if it were me
[18:21:54] <tjb1> I wouldnt know what to do with 384 :)
[18:21:56] <cradek> if you make "inside" corners you might get what you want (the drill is inside the part profile, touching both sides of the corner) but for an outside corner you'll find it makes no sense (the tool touches the outside corner in many positions along an arc)
[18:22:15] <Tom_itx> cradek the only moves to the z is a rapid
[18:22:18] <cradek> ... you'll get one of them
[18:23:08] <cradek> Tom_itx: the direction of that before move is part of what determines the position. also the one after your Z move.
[18:23:08] <Tom_itx> rapid..z move.. rapid.. z move..
[18:23:22] <cradek> you're making CORNERS whether you like it or not
[18:23:28] <cradek> turn off comp if you aren't cutting a profile
[18:23:29] <Tom_itx> ok
[18:23:32] <tjb1> Is cutter comp active during rapids?
[18:23:41] <Tom_itx> it's non modal i think
[18:23:48] <tjb1> I mean…will it apply cutter comp on a rapid move
[18:23:49] <cradek> tjb1: it stays on unless you turn it off
[18:24:40] <tjb1> andypugh: I need to save money now, school wont let me adjust loan anymore
[18:24:53] <tjb1> And I dont think I could ever use 384 I/O on a plasma table
[18:25:19] <andypugh> In that case, cut one end off of a parallel lead and use the wires.
[18:25:44] <andypugh> No point spending $25 to save a $20 parallel port card
[18:25:58] <tjb1> My card was actually $3 :)
[18:26:16] <tjb1> Havent found out if it works yet
[18:26:17] <andypugh> There you are. So don't worry about the BOB, wire direct
[18:26:42] <andypugh> Heck, I wire direct to Mesa cards and parallel ports.
[18:27:03] <tjb1> http://www.ebay.com/itm/PCI-IEEE-1284-Parallel-Printer-LPT-Port-I-O-Card-ECP-EPP-SP-C-/170732813053?pt=US_Internal_Port_Expansion_Cards&hash=item27c077fafd
[18:27:07] <Tom_itx> having the screw terminals is nice though
[18:27:11] <tjb1> It was 4.xx when i got it
[18:27:18] <Tom_itx> i wired a couple of mine direct
[18:27:33] <Tom_itx> after i filled up the 7i47
[18:28:04] <Tom_itx> i need pcw_home to advise me on configuring the 2nd port
[18:28:11] <Tom_itx> so i can add an encoder on it
[18:28:22] <andypugh> Tom_itx: Which board?
[18:28:29] <jdh> teh encoder should go on the 7i47
[18:28:40] <Tom_itx> 7i43 7i47 but it's the 2nd port on the 7i43
[18:28:52] <Tom_itx> jdh no room
[18:29:01] <Tom_itx> unless i rewire the whold damn thing
[18:29:19] <andypugh> Is there an encoder "function" on that connector?
[18:29:25] <Tom_itx> i'm not sure andy
[18:29:32] <Tom_itx> i haven't checked dmesg yet
[18:29:34] <andypugh> Which firmware?
[18:29:39] <Tom_itx> how do i tell?
[18:29:54] <taiden> is there a fast way to face a circle shape?
[18:29:58] <taiden> or pocket that shape
[18:30:01] <andypugh> It's in your INI file
[18:30:09] <Tom_itx> hang on
[18:30:32] <andypugh> taiden: Possibly.
[18:30:44] <taiden> i seem to remember a g2.1 or something starnge like that
[18:30:49] <andypugh> No, thinking harder, I don't think so
[18:30:50] <taiden> i can't seem to find it anymore though
[18:31:06] <atom1> firmware=hm2/7i43-4/SVST2_4_7I47B.BIT
[18:31:14] <jdh> taiden: there is a python thing for that
[18:31:30] <taiden> i'm just trying to throw a quick facing operation into a gcode file i have going
[18:31:30] <Tom_itx> andy, is that it?
[18:31:34] <andypugh> I wondering about using polar coordinates, but that won't work.
[18:31:41] <andypugh> Tom_itx: Yes
[18:32:00] <Tom_itx> i thought that was just for the 7i47
[18:32:07] <Tom_itx> combo
[18:32:11] <Tom_itx> not the 2nd port
[18:32:18] <taiden> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?G12-13
[18:32:35] <jdh> yeah, that one.
[18:32:39] <andypugh> No, that is the 7i43 firmware. The 7i47 is a passive device
[18:33:11] <Tom_itx> i think all the stepper encoder stuff is on the first port though isn't it?
[18:33:30] <Tom_itx> i'll look in a bit. need to get tool tables working first
[18:33:34] <andypugh> taiden: You could add that with mhaberlers marvelous G-code remapping.
[18:33:47] <andypugh> Tom_itx: Give me a moment
[18:33:59] <jdh> [ 4979.591540] hm2/hm2_7i43.0: IO Pin 004 (P4-09): Encoder #0, pin A (Input)
[18:33:59] <taiden> who dat?
[18:34:38] <andypugh> taiden: http://www.linuxcnc.org/docs/devel/html/remap/structure.html
[18:34:48] <andypugh> Not for the faint-hearted
[18:35:04] <atom1> i know
[18:35:33] <atom1> oh that wasn't for me
[18:36:27] <atom1> andy, dmesg shows the 2nd port all as gpio
[18:36:56] <andypugh> Tom_itx: You have 4 encoders there, I think.
[18:37:28] <atom1> i may have used those pins already
[18:37:32] <andypugh> Which pins of the other connector do you want an encoder on?
[18:38:02] <atom1> i'm not sure just yet
[18:38:14] <atom1> i need to look it over a bit more
[18:38:30] <atom1> i may be able to do it myself but i've never written or modded a bit file
[18:38:43] <atom1> i'm set up to do it
[18:39:23] <jdh> 7i47 was raised from birth to have encoders. You are trying to thwart its destiny.
[18:39:55] <atom1> jdh, i'm using one on it but i think i already used the other pins for gpio
[18:40:02] <atom1> i need to double check that
[18:40:27] <jdh> gpio is easy to move and you won't need the voltage divders on the other port
[18:40:27] <atom1> 4 6 and 8 are encoders
[18:40:49] <atom1> jdh, it's a single ended encoder from a printer
[18:40:58] <atom1> just an ir detector
[18:41:12] <atom1> for spindle speed
[18:41:16] <jdh> then you would still need them for that.
[18:41:34] <jdh> someday, I'll get mine mounted.
[18:42:35] <atom1> oh wait, i've only got one encoder loaded in the ini
[18:42:45] <atom1> i'm not sure what pins the 2nd one would fall on
[18:42:51] <andypugh> How many are you using?
[18:42:58] <atom1> ^^ was encoder 1
[18:43:01] <atom1> just one for my pendant
[18:43:25] <andypugh> There should be 4 on the 7i47
[18:43:38] <atom1> yeah but i wasn't using them so i only configured one
[18:43:55] <andypugh> So, why do you need an encoder on the second connector?
[18:44:20] <atom1> because i'm pretty sure i used the pins for something else already
[18:44:41] <atom1> i could move stuff around i suppose
[18:44:54] <andypugh> Ah, so you want encoder 1 to be on the second connector, and only encoder.0 on the 7i47?
[18:45:01] <andypugh> That seems… perverse
[18:45:07] <atom1> just for convenience
[18:45:23] <atom1> heh
[18:45:26] <atom1> i'll work it out
[18:45:36] <atom1> i'll probably move the gpio
[18:46:06] <andypugh> No, I have already built you a custom firmware once, it't no more trouble to make it even stranger.
[18:46:17] <atom1> you did?
[18:46:42] <andypugh> Well, I stopped it 75% through just then
[18:46:48] <atom1> heh sorry
[18:47:00] <atom1> i'd rather just know how to do it
[18:47:34] <atom1> http://tom-itx.dyndns.org:81/~webpage/emc/xilinx/xilinx_install_index.php
[18:47:41] <atom1> you knew about that right?
[18:48:28] <atom1> doesn't cover modding the actual files
[18:50:12] <atom1> i'll have to set it up again as i've reloaded the hdd
[18:51:41] <andypugh> Well, I just made myself a firmware about an hour ago, so I was sort of in the groove
[18:52:43] <atom1> i will likely just enable one more on the 7i47 and move the io to the 2nd port on the 7i43
[18:55:17] <atom1> how do i bring up the tool touch off dialog? MDI a Tx M6 ?
[18:57:55] <andypugh> I don't think you can from G-code. You need to use the GUI button
[18:58:15] <atom1> touch off?
[18:58:26] <atom1> how do i select the tool then?
[18:59:26] <JT-Shop> for the touch off dialog you have to load the tool first with Tn M6 G43
[19:00:33] <atom1> how do i get the work offset dialog back then or is it a separate dialog?
[19:01:09] <JT-Shop> what do you mean?
[19:01:31] <atom1> i loaded Tx M6 G43, now what?
[19:01:54] <atom1> jogged to where i want it set
[19:02:18] <atom1> ok nevermind i see it
[19:02:21] <JT-Shop> setting the Z material height or the tool offset from some fixed point?
[19:02:30] <atom1> tool offset
[19:02:42] <atom1> T Tool Table from the menu
[19:02:59] <JT-Shop> tool offset from the material or a fixed point?
[19:03:04] <andypugh> Yes. Get it right this time, and keep your 100% record. It won't last.
[19:03:36] <atom1> material
[19:03:55] <atom1> andypugh, :)
[19:04:23] <andypugh> atom1: Getting an impenetrable error. So as you have a better solution, I am going to give up.
[19:04:29] <JT-Shop> then make sure the touchoff to workpiece is selected
[19:04:57] <JT-Shop> and touch off your G54 or whatever coordinate system
[19:05:12] <andypugh> Night all
[19:05:14] <atom1> andypugh, what was that in regard to?
[19:05:17] <JT-Shop> night
[19:05:21] <atom1> night
[19:05:29] <atom1> guess we'll never know
[19:05:31] <andypugh> Building the custom firmware you don't want any more
[19:05:40] <atom1> but... but...
[19:05:49] <andypugh> Go on..
[19:05:57] <atom1> i didn't really ask you to build it
[19:06:10] <andypugh> I know.
[19:06:13] <andypugh> I was showing off.
[19:06:28] <atom1> i'll build one and you can see if it looks right
[19:06:38] <atom1> maybe
[19:06:48] <atom1> now back to the tool table
[19:13:28] <atom1> JT-Shop, i got the G54 set but when i manually change tools and write the new offset to the table it remains at zero
[19:13:43] <atom1> after reloading the tool table...
[19:14:03] <atom1> T10 M6 G43
[19:14:13] <atom1> jog to height and touch off to the table
[19:14:32] <atom1> T1 M6 G43 jog to new height and touch off to the tool table
[19:14:40] <atom1> both are zero
[19:15:54] <atom1> Touchoff to workpiece is selected
[19:16:39] <atom1> mm just a sec i may have figured something out here
[19:20:19] <JT-Shop> atom1, you seem to be skipping around and I can't keep up
[19:20:32] <atom1> start from the beginning then
[19:20:37] <atom1> i'll follow
[19:20:47] <atom1> if you have time that is
[19:20:59] <JT-Shop> ok say I'm setting up T1 and T2
[19:21:15] <atom1> using G54 offset.. ok
[19:21:49] <JT-Shop> first load the tool with T1 M6 G43
[19:22:02] <JT-Shop> then make sure touch off to fixture is selected
[19:22:31] <atom1> ok i thought you said touch off to workpiece at first
[19:22:38] <JT-Shop> now set tool 1 from say the vise jaw and make sure Z axis is selected
[19:22:40] <atom1> i selected fixture... go on
[19:22:53] <JT-Shop> then touch off the tool table
[19:23:14] <JT-Shop> now load tool 2 in the spindle and do a T2 M6 G43
[19:23:29] <JT-Shop> set the Z on it the same way as you did the first
[19:23:45] <JT-Shop> touching off to the tool table each time.
[19:23:59] <atom1> select the z axis from where?
[19:24:01] <JT-Shop> now change the touch off to workpiece
[19:24:18] <atom1> the tool table?
[19:24:19] <JT-Shop> on the manual tab make sure Z is the selected axis
[19:24:29] <atom1> oh ok, it is
[19:24:48] <JT-Shop> if you have X selected then you will touch off X not Z
[19:24:56] <atom1> right
[19:25:07] <atom1> i got that part. my G54 x y and z are all set
[19:25:07] <JT-Shop> ok, now both tools are set to a common point for Z
[19:25:15] <JT-Shop> g54 is not set yet
[19:25:21] <atom1> alright
[19:25:38] <JT-Shop> you have only set the relationship between the two tools in the tool table
[19:26:04] <atom1> where does axis indicate what tool is selected?
[19:26:10] <atom1> or does it?
[19:26:17] <JT-Shop> now load tool 1 with T1 M6 G43 and making sure that touch off to workpiece is selected
[19:26:23] <JT-Shop> bottom bar
[19:26:28] <JT-Shop> or the DRO tab
[19:26:29] <atom1> ok
[19:26:33] <atom1> yeah
[19:26:47] <JT-Shop> now touch off G54 to the workpiece
[19:27:01] <atom1> ok lemme catch up here
[19:27:16] <JT-Shop> now when you load tool 2 and do a G0 Z0 it will be the same Z as tool 1
[19:27:24] <JT-Shop> ok
[19:28:50] <atom1> when setting the tools does it matter if i jog first or select the tool first before writing the value?
[19:29:40] <JT-Shop> doesn't matter so long as the correct axis is selected before you touch off
[19:29:49] <atom1> just checking
[19:30:20] <r00t4rd3d> how do you select the tool out of the tool table?
[19:30:58] <r00t4rd3d> normally when i do something it says No Tool at the bottom
[19:30:59] <JT-Shop> in g code?
[19:31:10] <r00t4rd3d> what if i dont know how
[19:31:18] <JT-Shop> Tn M6 G43
[19:31:22] <r00t4rd3d> why is the tool table in there if i cant use it?
[19:31:39] <JT-Shop> dunno why you can't use it
[19:31:43] <r00t4rd3d> i should be able just click on one
[19:31:55] <r00t4rd3d> check box, use this tool
[19:32:11] <JT-Shop> you can, you just have to program that in
[19:32:42] <atom1> JT-Shop, both tools show zero in the Z offset in the tool table after setting them
[19:33:04] <atom1> and reloading the tool table...
[19:33:13] <JT-Shop> are they the same lenght
[19:33:20] <atom1> no
[19:33:42] <JT-Shop> you have done something wrong or missed a step somehow
[19:34:22] <atom1> ok, 1) tool touch off to fixture is selected
[19:34:40] <atom1> 2) T10 M6 G43
[19:34:47] <atom1> 3) jog to point
[19:34:58] <atom1> 4) Touch off to table
[19:35:11] <atom1> 5) T1 M6 G43
[19:35:18] <JT-Shop> touch off to T?
[19:35:19] <atom1> 6) jog to point
[19:35:24] <atom1> yes
[19:35:43] <JT-Shop> stop and look at your tool table for tool 10
[19:35:44] <atom1> 7) touch off to T again
[19:35:54] <atom1> before or after reloading it?
[19:36:02] <taiden> evening gents
[19:36:07] <JT-Shop> you don't have to reload the tool table
[19:36:14] <JT-Shop> unless you manually edit it
[19:36:26] <taiden> so im having an interesting problem
[19:36:26] <atom1> maybe that's what i'm doing wrong
[19:36:30] <atom1> it may be zeroing it from the file
[19:36:41] <atom1> lemme try once more
[19:36:42] <taiden> it's probably my own doing tbh
[19:36:55] <taiden> i have a subroutine that cuts a circle, quite simple
[19:37:01] <taiden> it's in my subroutine folder
[19:37:05] <taiden> when i call it from MDI it works perfectly
[19:37:11] <r00t4rd3d> lol Digg just sold for 500k
[19:37:23] <taiden> but when I call it from within an *.ngc file
[19:37:42] <taiden> axis preview shows that the circles are about double the diameter as intended
[19:37:50] <taiden> and it gives me massive warnings when it ry to run it anyway
[19:38:09] <taiden> i'm not passing it variables
[19:38:19] <taiden> the subroutine uses all locally scoped variables
[19:40:20] <atom1> JT-Shop, do i need to enter the value from the DRO display in the dialog box before writing the tool table?
[19:40:36] <atom1> or is it stored in a var automatically
[19:40:43] <JT-Shop> I use 0 when I touch off to a fixture
[19:40:59] <atom1> i'm still working on the tools
[19:41:22] <JT-Shop> set one then look to see if the tool table has changed
[19:41:35] <atom1> it didn't
[19:42:43] <atom1> it changed to red and said it had been updated by an outside source
[19:43:32] <ReadError> http://i.imgur.com/5v6bH.jpg
[19:43:35] <ReadError> i cut it again
[19:43:38] <ReadError> less depth
[19:43:41] <ReadError> think it turned out better
[19:43:52] <ReadError> i need to tweak some stuff still
[19:44:03] <atom1> ok after reloading it, it was different
[19:45:38] <JT-Shop> yea you don't really want the tool table editor open when you touch off to the tool table
[19:46:12] <JT-Shop> taiden, it's impossible to guess without more information
[19:46:28] <atom1> JT-Shop, ok they both have non zero numbers in them
[19:46:37] <JT-Shop> YEA!
[19:46:37] <atom1> now to the G54 offset
[19:46:54] <atom1> so are those values relative to machine zero?
[19:47:01] <JT-Shop> yea
[19:47:10] <atom1> so they will always be negative
[19:47:19] <JT-Shop> usually for Z
[19:47:30] <atom1> just verifying what i see
[19:47:33] <JT-Shop> make sure you have touch off to workpiece selected
[19:47:50] <atom1> ok so for the tools you touchoff to fixture
[19:48:01] <atom1> and for the offsets you touchoff to workpiece?
[19:48:02] <taiden> alright it appears to be only a rendering issu
[19:48:20] <taiden> because it runs fine
[19:48:28] <taiden> but axis freaks out whenever i try to run it
[19:48:33] <atom1> JT-Shop, ok touchoff to workpiece is selected
[19:48:57] <atom1> T2 is still active
[19:49:06] <JT-Shop> if your using a dowel then enter that diameter in the touch off window
[19:49:11] <atom1> (per your example)
[19:49:14] <JT-Shop> when you touch off
[19:49:36] <atom1> well i offset it in my cad so i don't need that
[19:49:45] <atom1> i can use zero there
[19:49:50] <JT-Shop> ok
[19:49:59] <atom1> you follow that right?
[19:50:19] <JT-Shop> yea, a bit prone to mistakes at least for me
[19:50:21] <atom1> i just lower the model in my cad by the offset value
[19:50:30] <atom1> it's how i've always done it :)
[19:50:46] <JT-Shop> should be good for you then
[19:50:54] <atom1> ok carry on..
[19:51:18] <atom1> so enter the G54 offset value using any tool?
[19:51:27] <JT-Shop> yea
[19:51:39] <atom1> it says it's zero right now
[19:51:42] <JT-Shop> each tool has been set to each other
[19:51:47] <taiden> anyone have any ideas why axis is rendering my subroutine wrong?
[19:52:22] <JT-Shop> load tool 1 and move to the same Z position and it should be 0 too
[19:52:45] <atom1> i can verify that by subtracting the offset difference between the 2 tools in this case
[19:52:53] <atom1> ok
[19:53:47] <JT-Shop> I never look at the tool table
[19:54:06] <atom1> heh
[19:54:19] <atom1> you can sometimes spot obvious mistakes there
[19:54:25] <atom1> i jogged and it's right
[19:54:58] <JT-Shop> I spot my obvious mistakes by loading the tool and jogging to a known postion then look at the dRo
[19:55:23] <atom1> so in review, touch to fixture to set the tool offset and touch to workpiece to set the z zero fixture offset
[19:55:25] <atom1> ?
[19:56:17] <atom1> i was manually editing the table but it wasn't set from machine zero, rather from the tool offset difference
[19:56:27] <atom1> that's where i went wrong
[19:56:45] <JT-Shop> sounds right
[19:56:50] <atom1> and not having the right touch off selected in the Machine menu
[19:56:59] <atom1> alright, i'll run a test and see
[19:57:13] <JT-Shop> ok
[19:57:13] <atom1> well above the material
[19:59:21] <atom1> ok it looks right
[19:59:21] <atom1> thanks alot
[20:00:01] <atom1> JT-Shop, now tell me what your button does ;)
[20:00:31] <JT-Shop> well I have one button that performs the touch off to material for me
[20:00:50] <atom1> does it write to the tool table?
[20:00:51] <JT-Shop> that way I don't have to remember to do anything
[20:00:57] <JT-Shop> yep
[20:01:22] <atom1> select the tool, jog to position and push the button?
[20:02:05] <JT-Shop> yea
[20:03:50] <JT-Shop> I have a button to select each tool too
[20:04:55] <JT-Shop> going live online with a customers PLC now
[20:17:27] <Tom_itx> i need a tool rack now with all my preset tools
[20:17:45] <Tom_itx> grab a tool, select it, set the fixture offset and go
[20:17:53] <Tom_itx> (living dangerously of course)
[20:18:15] <Tom_itx> in theory that should work though
[20:18:59] <taiden> i like to lower my Z onto a block of known height and then tighten up the chuck
[20:19:07] <taiden> i'm trying to figure out how to do that in a program with multiple tool changes
[20:19:22] <taiden> emc2 wont let me jog with the tool change dialog up (probably for good reason)
[20:19:37] <taiden> and by lower my z i mean lower my tool
[20:20:16] <Jymmm> JT-Shop: New toy to add to your cannon... http://sfbay.craigslist.org/sby/zip/3128405172.html
[20:21:07] <Tom_itx> taiden you might ask andypugh when he comes back, i think that may be something he was working on to add
[20:22:10] <Tom_itx> but unless you have separate tool holders like i do and enter the values in the tool table you would be better off splitting the program up by tool
[20:23:10] <JT-Shop> YEA finally whipped that PLC's ass into submission
[20:24:38] <JT-Shop> Tom_itx, you made him mad and he quit
[20:25:25] <Tom_itx> aww
[20:25:37] <Tom_itx> isn't that something andy is working on?
[20:25:47] <Tom_itx> for those that don't have tool changers
[20:26:22] <JT-Shop> don't think so, Les did something a while back but it is not really practical to do so
[20:26:38] <Tom_itx> hmm i'd have sworn i heard andy talk about it
[20:26:55] <JT-Shop> my touch off to material button just runs a mdi command so it is really simple
[20:27:14] <Tom_itx> G10?
[20:27:43] <Tom_itx> i forget.. G10 L2 something something
[20:28:18] <JT-Shop> MDI_COMMAND = G10 L20 P1 Z0.375
[20:29:26] <JT-Shop> you just make a pyvcp button to execute a halui.mdi.command...
[20:29:33] <Tom_itx> yeah
[20:29:52] <r00t4rd3d> i wish i knew what you guys were talking about
[20:30:04] <Tom_itx> i did that once for my fixture home
[20:30:11] <Tom_itx> i like it
[20:30:28] <Tom_itx> i got a feeling i'll be adding more buttons soon
[20:30:48] <Tom_itx> maybe a whistle or two
[20:31:14] * JT-Shop smiles that the customer is happy and dinner was good so time to chill
[20:31:27] <Tom_itx> thanks for the help
[20:31:43] <JT-Shop> r00t4rd3d, I'll catch you up in the morning if your on
[20:31:48] <JT-Shop> Tom_itx, np
