[00:00:22] <tjb1> Got a max of 632
[00:00:33] <tjb1> that comes out to about 154 volts if my math is correct
[00:01:27] -!- tjb1 has quit [Read error: Connection reset by peer]
[00:02:35] <Connor> tjb1 must have shorted something out. :)
[00:03:08] -!- tjb1 [tjb1!~tjb1@225.sub-174-255-49.myvzw.com] has joined #linuxcnc
[00:03:31] <tjb1> That sound about right?
[00:03:54] <Connor> I know nothing about plasma voltage
[00:04:10] <tjb1> Its just math :)
[00:04:17] <tjb1> 632 = 3.088v
[00:05:18] <tjb1> Maybe its 216 volts...
[00:05:39] <Connor> whats the ohm's on the VD ?
[00:05:50] <tjb1> VD?
[00:05:55] <Connor> Voltage Divider
[00:06:00] <tjb1> 2k-5k
[00:06:05] <tjb1> takes 7 to 5
[00:06:30] <tjb1> means 4.323 is coming into divider
[00:06:55] <tjb1> Yeah 216 volts
[00:07:05] <tjb1> 4.323*50
[00:08:04] <Connor> Umm...
[00:08:07] <Connor> wait.
[00:08:16] <Connor> you have a 2k and a 5k for the Voltage divider ?
[00:08:21] <tjb1> yes
[00:08:29] <Connor> what's the output before the VD ?
[00:08:34] <tjb1> max of 7
[00:08:41] <Connor> okay.
[00:09:19] <Connor> okay, so. 7v is what voltage for the plasma ?
[00:09:30] <tjb1> 350
[00:10:11] <Connor> okay. so .02mv per v
[00:10:33] <Connor> and you need to scale the 7 down to 5
[00:11:02] <tjb1> If I reverse the voltage divider calculator
[00:11:04] <tjb1> 3.088 out is
[00:11:11] <tjb1> 4.323 in
[00:11:23] <tjb1> Take that times 50 and its 216
[00:13:57] <tjb1> For the arduino I just need to take the analog voltage and multiply that by 70.142 to get the arc voltage
[00:14:21] <tjb1> I can display that on a 16x2 LCD
[00:14:27] <tjb1> Use pot to adjust range
[00:15:03] <Tom_itx> you may want to add a resistor to the pot wiper in case of a short
[00:15:25] -!- Thetawaves [Thetawaves!~Thetawave@7-139-42-72.gci.net] has joined #linuxcnc
[00:15:37] <tjb1> Where?
[00:16:28] <Tom_itx> usually if you turn a pot all the way it will hit the end stops and be 0 ohm
[00:16:37] <Tom_itx> adding a resistor to the wiper will prevent that
[00:16:44] <Tom_itx> unless you desire that effect
[00:16:58] <tjb1> So a resistor there will make it whatever the resistor value is
[00:17:08] <Tom_itx> yeah
[00:17:11] <tjb1> and if its a 10k the high value will be 10k + resistor?
[00:17:14] <Tom_itx> like 100 ohm or something
[00:17:32] <Tom_itx> test it
[00:17:33] <Tom_itx> and see
[00:17:42] <tjb1> I gotta go install cabinets
[00:17:45] <tjb1> Done testing for now
[00:18:12] <tjb1> Next step is either having arduino solely control the z axis or send the signals into linuxcnc
[00:21:50] <tjb1> So my THC will work for hypertherm plasma :)

[01:38:43] <jdh> if you have an inflator hose, you can get an adapter that plugs in and has npt
[01:39:02] <Connor> The both have standard BC hoses.
[01:39:08] <Tom_itx> Valen, i took all the extra moves out of my program and bumped the feed/speed up some. works like a champ
[01:39:17] <Connor> the quick release ones..

[01:41:13] <jdh> dive shops have them. sometimes with tire inflators on them.
[01:41:21] <Connor> ok
[01:41:59] <Connor> I'll visit Rheas Dive shop in Maryville.. or see if there is a one here close by
[01:42:35] <jdh> or cut a crappy hose and stick a barb fitting on it.
[01:43:11] <Valen> i thaught it might ;->
[01:43:25] <Valen> anyway time to go do some milling myself
[01:43:51] <Tom_itx> i didn't bump it up alot but some
[01:44:02] <Tom_itx> getting rid of the extra passes was a big help
[01:45:12] -!- Thetawaves has quit [Quit: This computer has gone to sleep]
[01:45:28] <Tom_itx> ok i've got a question about cutting plastics. how does plexiglas cut compared to ABS? as far as heat, feeds and speeds etc
[01:46:59] KimK_ is now known as KimK
[01:48:15] <Valen> plexiglas acrylic or polycarb?
[01:48:23] <Tom_itx> acrylic
[01:48:36] <Valen> its easier to cut
[01:49:00] <Valen> abs is soft, acrylic is hard so it shaves off easier
[01:49:21] <Tom_itx> ok, going from a .031" cutter to a .187 and ABS to acrylic how much should i adjust the feed?
[01:49:32] -!- taiden [taiden!~lukepighe@cpe-184-153-132-154.maine.res.rr.com] has joined #linuxcnc
[01:49:47] <Tom_itx> i was feeding the .031 at 8 ipm and it was doing real good
[01:49:58] <Tom_itx> i don't wanna get the acrylic hot
[01:50:01] <Valen> i dunno the numbers i'd just to some test cuts until it seems the sweet spot
[01:50:13] <Tom_itx> yeah it takes a while to find it
[01:50:30] <Valen> just do cuts in the bulk plastic, not making parts
[01:50:36] <Tom_itx> i gotta get my spindle encoder working
[01:50:42] <Tom_itx> pfft
[01:51:06] <Tom_itx> should i make 2 passes in .250" material or just one?
[01:51:23] <Tom_itx> i'm afraid it will ball up on the cutter
[01:51:24] <Valen> what size cutter?
[01:51:30] <Valen> nah it shouldn't ball
[01:51:30] <Tom_itx> .187"
[01:51:44] <Valen> nah it should do it in one pass ok
[01:51:54] <Tom_itx> i'll hold you to your work :D
[01:51:57] <Tom_itx> word*
[01:51:58] <Valen> we cut 3mm with a 2mm cutter in one pass
[01:52:25] <Valen> i'm not usually the person running the machine so i don't rember the details
[01:52:58] <Tom_itx> i've got extra plastic i just don't wanna break a new cutter
[01:53:20] <Tom_itx> .218" thick material
[01:53:20] <Tom_itx> just mic'd it
[01:53:56] <Tom_itx> 7/32"

[02:01:09] <taiden> there seems to be a single place that sells them but they are for $100+ glue guns
[02:01:22] <Connor> wonder if two of those would work for the setup..
[02:01:24] <taiden> I use a $5 glue gun that works fine but the reach isn't good enough
[02:01:34] <Connor> looks like they're good up to 142PSI

[03:31:46] <Tom_itx> any way i try doesn't seem to be right
[03:32:17] <Tom_itx> i guess i may have to break the program up by tools until i can figure out how the table works in relation to the z fixture offsets.
[03:36:42] -!- ve7it has quit [Remote host closed the connection]
[03:41:32] <toastydeath> Tom_itx, traditionally the first tool sets the work plane and then all other tools are touched off from that plane - i.e. relative to the first tool's length
[03:50:14] <Tom_itx> well it isn't working like that
[03:50:36] <Tom_itx> that's kinda what i thought too. it's how we normally set our machines up
[03:50:47] <Tom_itx> but i'm still getting used to linuxcnc
[03:51:17] <Tom_itx> i tried setting with the first tool in the program and also with the first tool in the tool table
[03:51:29] <Tom_itx> and each time the 2nd tool called up had the wrong offset
[03:52:16] <Tom_itx> i'm not using touchoff. rather presetting the tool lengths and entering them in the table
[03:52:37] <Tom_itx> and using the first tool called as zero offset for both the tool and the work offset
[03:54:13] <Tom_itx> i broke the program up into tools and it works fine
[03:54:29] <Tom_itx> i would like to figure out how the tool table is supposed to work though

[03:54:49] <tjb1> Got the two island cabinets in, perfectly level and with a perfect 24" gap between them
[03:54:55] <tjb1> Im ecstatic
[03:54:56] <Tom_itx> we would typically use a dowel pin to set the initial tool and fixture zero

[03:55:11] <Tom_itx> and set all the tools from that
[03:55:33] <Tom_itx> and that's what i tried here but it didn't work as expected
[03:58:41] <Tom_itx> i don't have a tool changer but i did set up manual tool change and that part works fine as well.
[03:59:35] <Tom_itx> i can post each tool separately but it's a pita and hopefully can be avoided
[04:01:58] <Tom_itx> toastydeath, does the first tool need to be the longest or does that matter?
[04:02:02] <Tom_itx> it shouldn't matter
[04:02:09] <toastydeath> doesn't matter
[04:02:15] <toastydeath> there's some best practice argument
[04:02:17] <Tom_itx> you just adjust your offset positive or negtive accordingly
[04:02:23] <Tom_itx> i know
[04:02:32] <Tom_itx> best to set the longest first probably

[04:02:48] <toastydeath> i'm sure you've experienced the same, it doesn't help the majority of crashes
[04:02:53] <Tom_itx> that's why i'm testing it well above the work first

[04:04:48] <Jymmm> Tom_itx: just set zero 2" higher than it should be =)
[04:04:54] <Tom_itx> i am
[04:05:16] <Tom_itx> then i check where the tool should be with a 123 block
[04:05:29] <Tom_itx> and it's not where it should be yet :)
[04:05:38] <Jymmm> how do you mean?
[04:05:49] <Tom_itx> i start with T10
[04:05:54] <tjb1> How do you keep your tools from rusting when they sit in the toolbox for an extended time?
[04:06:05] <Tom_itx> set z zero offset and set the tool to zero offset
[04:06:13] <toastydeath> tjb1, light oil
[04:06:15] <Tom_itx> next tool i set relative to that point
[04:06:19] <toastydeath> also, keep them in a dry place
[04:06:27] <Tom_itx> and enter z in the tool table
[04:06:32] <toastydeath> and keep some kind of dessicant in the box drawers
[04:06:32] <Jymmm> tjb1: fill the draw full of oil

[04:06:38] <tjb1> Well I dont exactly have a choice at school
[04:06:58] <tjb1> I have 1-2-3 blocks rusting, a grinding vise, sine bar...
[04:07:03] <Jymmm> oil soaked rag, then wrap in foil
[04:07:14] <Tom_itx> cosmolene
[04:07:19] <Jymmm> Tom_itx: ew
[04:07:26] <Tom_itx> very effective
[04:07:32] <Jymmm> no cosmolene@
[04:07:54] <tjb1> What takes rust off without ruining the finish?
[04:08:07] <Tom_itx> pickling
[04:09:14] <Tom_itx> http://en.wikipedia.org/wiki/Pickling_%28metal%29
[04:09:59] <tjb1> So just dip them in hydrochloric acid
[04:10:21] <Tom_itx> i'd try another approach before i did that
[04:10:33] <Jymmm> CLR?
[04:10:53] <tjb1> Wonder if blaster and a paper towel would do any good
[04:11:13] <Tom_itx> 3m pad
[04:11:19] <Tom_itx> and some oil
[04:11:21] <Jymmm> just rub them with oil and LIGHTLY with a scotchbright pad
[04:11:29] <Tom_itx> that's what i just said
[04:11:31] <Tom_itx> :)
[04:11:49] <tjb1> I did walmart gun blue most of the stuff I made
[04:11:51] <Jymmm> Tom_itx: you didn't say LIGHTLY biotch =)
[04:11:55] <tjb1> It helped but they still rusted a little
[04:12:02] <Jymmm> tjb1: So?
[04:12:09] <Jymmm> tjb1: MORE oil
[04:12:12] <Tom_itx> and a white 3m pad is finer than say the green or blue or purple
[04:12:24] <tjb1> I shall oil the hell out of them :)
[04:12:33] <Jymmm> tjb1: monthly
[04:12:45] <tjb1> weekly.
[04:12:46] <tjb1> ;)
[04:13:59] <Jymmm> minutely
[04:14:10] <Tom_itx> pickling will sometimes leave pits and you don't really want that
[04:14:22] <Tom_itx> if the rust has done the damage already
[04:18:10] <tjb1> Im certainly not re grinding the stuff
[04:18:32] <toastydeath> scrape it in
[04:18:35] <toastydeath> clearly
[04:18:39] <tjb1> I despise surface grinding
[04:18:52] <toastydeath> lol what
[04:18:57] <toastydeath> how can you hate grinding
[04:19:03] <toastydeath> it's long and you can walk off and do other bullshit
[04:19:32] <tjb1> Ive never gotten to use the auto grinders
[04:19:55] <toastydeath> Oh.
[04:19:55] <tjb1> Now do you understand? :)
[04:19:59] <toastydeath> that would explain it, yeah.
[04:20:11] <tjb1> Sit there for hours and get a huge left arm
[04:20:25] <toastydeath> does it have auto feed on Y
[04:20:32] <tjb1> No it was all manual

[04:20:50] <toastydeath> really?
[04:20:56] <tjb1> Yep
[04:20:58] <toastydeath> every single stroke on X you have to move it by hand
[04:21:04] <tjb1> Yes
[04:21:05] <toastydeath> is the X auto at least?
[04:21:09] <tjb1> Nothing was auto
[04:21:17] <toastydeath> I'd crush feed it
[04:21:40] <toastydeath> near full depth, full pass on wheel width
[04:21:45] <toastydeath> slow as balls
[04:22:02] <tjb1> Slow as balls, one false move and you blow the wheel up
[04:22:06] <toastydeath> neg
[04:22:12] <toastydeath> you're doing it in the wrong direction if that happens
[04:22:20] <tjb1> feed against then
[04:22:24] <toastydeath> yep.
[04:22:35] <toastydeath> then you only have to do one final pass
[04:22:38] <tjb1> Always dressing the damn wheel...

[04:23:11] <tjb1> It was the highlight of my monday and wednesdays from 5 til 9pm
[04:23:31] <toastydeath> something's wrong if you're redressing the wheel THAT often
[04:24:02] <tjb1> Its a school, we cant leave them on :)
[04:24:09] <tjb1> Turn them off, then turn them back on and off then on
[04:24:37] <toastydeath> ...?
[04:24:48] <tjb1> Suppose to leave surface grinders run
[04:25:08] <toastydeath> you have a lot of spindle movement as it warms up, i guess
[04:25:14] <toastydeath> sucks
[04:25:21] <tjb1> Then the chance the wheel slips off center
[04:25:27] <toastydeath> get really good at flycutting then
[04:25:32] <tjb1> Easier to dress then to screw it up
[04:25:53] <toastydeath> we got really good at flycutting large pieces and on a good mill it rivals grinding for most tolerances
[04:26:07] <tjb1> Most of the stuff we were grinding was made 2-3 semester earlier so you didnt want to screw it up
[04:26:31] <tjb1> Yeah thats another problem, we have no good cutters
[04:26:42] <toastydeath> flycutting is no harder to do than grinding
[04:26:52] <tjb1> If there is a carbide cutter someone has cranked the insert in so hard that you have to break the insert to get it out
[04:27:09] <tjb1> They really shouldnt let the students change inserts
[04:27:32] <tjb1> Ive broken/stripped/twisted multiple allen wrenches
[04:27:36] <toastydeath> lol
[04:27:38] <toastydeath> i love students
[04:28:05] <toastydeath> I saw one kid accidentally discover friction welding when he ran a 1" hss bit backwards at 2400 rpm
[04:28:08] <toastydeath> through steel
[04:28:19] <tjb1> No surprise
[04:28:57] <tjb1> We have an edm teacher, not sure if he is serious but he said this one metal pipe was to listen to the arc
[04:29:09] <tjb1> No way in hell I am sticking a metal pipe near a wire edm

[14:58:10] <Tom_itx> JT-Shop you around?
[14:59:06] <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.
[14:59:59] <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
[15:00:20] <Tom_itx> i tried entering it both as a positive and negative number thinking i screwed that up
[15:01:17] <Tom_itx> i set G54 z zero with the first tool called in the program and set both z offsets to zero
[15:01:28] <Tom_itx> and set the other tools relative to to that
[15:02:52] <jdh> t<n> M6 G43?
[15:03:36] <jdh> or G43 H<n>?

[15:15:35] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/cnc/cnc_files/enc_hub.txt
[15:15:40] <Tom_itx> there's a sample of my cam output
[15:16:37] <Tom_itx> the offset move is generally called on a z move
[15:18:25] <jdh> does that work?
[15:18:36] <Tom_itx> for the first tool yes
[15:18:51] <Tom_itx> because it's a zero offset
[15:18:55] <Tom_itx> i guess
[15:19:07] <Connor> What does it do 2nd time around ?
[15:19:07] <Tom_itx> a 2nd tool would be off by the tool table offset
[15:19:23] <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
[15:19:31] <Tom_itx> JT-Shop i've got all day
[15:19:36] <Tom_itx> week
[15:19:37] <Tom_itx> month
[15:19:39] <Tom_itx> :D
[15:20:06] <jdh> did your CAM generate this?
[15:20:10] <Tom_itx> if i need to change the cam output format i can
[15:20:11] <Tom_itx> yes
[15:20:45] <Connor> Why not just use the tool table for the offset and be done with it ?
[15:20:50] <Tom_itx> i modded my other sherline one specifically for linuxcnc
[15:21:00] <Tom_itx> Connor that's the issue, i'm trying to
[15:21:12] <Tom_itx> but the offsets are off
[15:21:33] <Connor> I don't think the cam needs to do the H1
[15:21:54] <Tom_itx> it doesn't by default but it's VERY good practice
[15:22:08] <Tom_itx> you can use an alternate H word on a tool if you feel like it
[15:22:10] <jdh> what is the Z for on the G43 line?
[15:22:22] <Tom_itx> move to the z clear height probably
[15:22:33] <Tom_itx> yes
[15:22:55] <Tom_itx> that's what the cam does, hand written it wouldn't need to be there
[15:23:03] <jdh> looks odd between the G43 and the H1
[15:23:15] <Connor> Tom_itx: Did you make sure to RELOAD the tool table after making changes to the tool height ?
[15:23:18] <Tom_itx> that's the format all other machines i've used like

[15:24:10] <Tom_itx> i may have stole one though
[15:24:38] <Tom_itx> fanuc, okuma, tree, fadal all use that format
[15:25:05] <jdh> they use Nnnn too, doesn't make it good :)
[15:25:11] <JT-Shop> G43 does not cause any motion. The next time a compensated axis is moved, that axis’s endpoint is the compensated location.
[15:25:13] <Connor> I was testing from the MDI.. and I never had to do the G43 command for tool offset.
[15:25:24] <Tom_itx> JT-Shop right
[15:25:30] <Tom_itx> should the move be on a separate line?
[15:25:36] <Tom_itx> or does it matter
[15:25:47] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/cnc/cnc_files/enc_hub.txt
[15:25:54] <Tom_itx> JT-Shop ^^ there's a sample output
[15:25:58] <JT-Shop> I would assume a separate line
[15:26:11] <Tom_itx> and it's a rapid move
[15:26:21] <Tom_itx> which shouldn't matter
[15:26:41] <Connor> or maybe I was just calling G43 outright..
[15:26:51] <Connor> I'll have to look on the machine.
[15:27:07] <Tom_itx> or instead of G43 Z-0.9 H1 maybe format it like: G43 H1 Z-0.9
[15:27:13] <Tom_itx> that also shouldn't matter
[15:27:57] <Tom_itx> i plan to leave the H word in as it is just good practice
[15:28:05] <JT-Shop> if you load each tool with Tn M6 G43 then jog to a point does the dro agree with your expectations?
[15:28:16] <Tom_itx> not on the 2nd tool
[15:28:27] <Tom_itx> the first tool called has a zero offset
[15:28:33] <Tom_itx> in one case it was T10

[15:29:35] <JT-Shop> do you have touch off to fixture or workpiece selected when you touch off Z0 G54?
[15:29:47] <Tom_itx> i use the touchoff dialog
[15:29:57] <Tom_itx> for the fixture
[15:30:09] <Tom_itx> and verify it on the axis display

[15:44:20] <Tom_itx> JT-Shop i think i see what you mean
[15:44:47] <Tom_itx> Touch tool off to workpiece vs Touch tool off to fixture
[15:44:51] <Tom_itx> which one should i use?
[15:45:51] <Tom_itx> it should be fixture for using G54..59 offsets shouldn't it?
[15:46:22] <r00t4rd3d> I thought you used that with a touch off plate or something
[15:47:42] <Tom_itx> but i'm not 'touching off'
[15:47:50] <Tom_itx> rather entering an offset value manually
[15:48:54] <r00t4rd3d> im gonna make a touch off plate
[15:48:58] <Tom_itx> i'll try it both ways later on and just see
[15:49:03] <r00t4rd3d> http://www.youtube.com/watch?v=PAeQZ3ux2NY
[15:49:13] <Tom_itx> just read the axis manual on it
[15:52:27] <cradek> use MDI to enter an offset value directly
[15:52:47] <cradek> touch off isn't for that
[15:53:08] <cradek> touch off is for edgefinder-like activity
[15:54:23] <Tom_itx> well i use it for edge finder too
[15:54:39] <Tom_itx> but use the tool tip of the first tool to set G54 z zero
[15:54:57] <cradek> ok that's exactly what touch off is for
[15:55:02] <Tom_itx> the rest are manually entered into the tool table z offset value

[16:17:38] <JT-Shop> ok
[16:18:19] <JT-Shop> Tom_itx, do you have presettable tools ie not R8?
[16:18:25] <Tom_itx> yes
[16:18:30] <Tom_itx> separate collets
[16:19:00] <JT-Shop> so you can take tool out of the spindle then put it back and the Z offset is the same?
[16:19:28] <Tom_itx> yes

[16:20:02] <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
[16:20:44] <Tom_itx> that's basically how i did it
[16:21:09] <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
[16:21:11] <JT-Shop> so for example with Machine > Touch off to fixture selected you set the tool table Z for each tool
[16:21:16] <Tom_itx> then set the others relative to that

[16:21:54] <Tom_itx> it may be better to try it when i'm at the machine
[16:22:02] <Tom_itx> but i'll take note anyway
[16:22:12] <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
[16:23:10] <Tom_itx> what difference does that touch to workpiece vs touch to fixture make?
[16:23:15] <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
[16:23:50] <Tom_itx> yeah, i do that too but i offset it in the cad and just enter the value
[16:24:00] <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
[16:24:16] <Tom_itx> so i want touch to workpiece selected then right?
[16:24:28] <cradek> this is very carefully described in the docs
[16:24:46] <JT-Shop> :-)
[16:24:47] <Tom_itx> i went over it cradek
[16:25:02] <Tom_itx> but i'm not at the machine to test it right now

[16:25:43] <cradek> ... but I can't find it :-/
[16:25:49] <JT-Shop> I made a pyvcp button to touch off to material as I always use the same size dowel to gauge with
[16:26:01] <Tom_itx> cradek i read it already

[16:27:33] <JT-Shop> crap I see a borked link
[16:29:07] <Tom_itx> i don't use the G10 to set the offsets
[16:29:08] <Tom_itx> should I?
[16:29:17] <cradek> touch off calls G10
[16:29:20] <Tom_itx> i manually edit the tool table
[16:29:25] <Tom_itx> oh ok

[16:31:02] <jthornton> what do you mean Tom_itx ?
[16:31:17] <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
[16:31:33] <Tom_itx> don't you use a tool for that?
[16:31:49] <jthornton> the button just does the g code to set the offset
[16:31:55] <Tom_itx> or do you use a dowelpin in a tool fixture
[16:31:58] <Tom_itx> we used to do that
[16:32:07] <Tom_itx> oh ok
[16:32:31] <Tom_itx> i'll fiddle with it later on and see if i can work it out
[16:32:33] <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
[16:32:47] <Tom_itx> i'm not sure where the workpiece vs offset was set in the menu

[17:06:45] <jdh> how are you planning on getting the tanks filled?
[17:06:57] <Connor> I'm certified.
[17:07:07] <jdh> I meant hydro/vip
[17:07:27] <Connor> Oh. I'll have to have them hydro'd probably.. they both are still full though.
[17:07:45] <Connor> 2000psi in the one I was using to test with last night.
[17:07:47] <jdh> steel or aluminum?
[17:07:59] <Connor> steel. So, they were only filled to 2200

[17:14:28] <jdh> using belleville washers?
[17:14:46] <Connor> Probably could get away without it..
[17:15:11] <jdh> if you need 1500psi of force to hit it, you won't need any to self-return
[17:15:12] <Connor> but.. I think you need the retract to make sure the piston isn't touching the spindle.
[17:15:40] <Connor> so, without full retract, it'll be touching the top of the draw bar.
[17:16:13] <jdh> oh, that might be needed. Can you use the quill at all with that?
[17:16:14] <Connor> not to mention since it's a floating setup.. it might cause it to not drop back down.
[17:16:34] <Connor> I will have a plate that I can remove that allows me to use the quill.
[17:16:51] <Connor> the plate that goes under the washers..
[17:17:17] <jdh> you should be able to get a double solenoid that goes both ways
[17:17:36] <Connor> You can, but then the cylinder will have continues pressure on it all the time.
[17:17:41] <Connor> which I don't want.
[17:17:58] <jdh> then it won't stay retracted
[17:18:05] <Connor> Yea it will.
[17:18:13] <Connor> friction
[17:18:22] <Connor> it's hard to move manully.
[17:18:50] <jdh> it will be harder to move with lines plugged

[17:30:17] <andypugh> IP rating describes the accessibility to fluids of the contacts.
[17:31:01] <archivist> from where though
[17:31:04] <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.
[17:32:08] <Jymmm> andypugh: Ok, so it's rated as when plugged in.
[17:32:12] <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.

[19:16:59] <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.
[19:17:17] <gene77> But I haven't a clue how to go about that...
[19:17:22] <MrSunshine> humm ?
[19:17:25] <MrSunshine> you burning fuses? :)
[19:17:48] <MrSunshine> and what do you mean with "spindle error term gets to big" ?
[19:17:57] <jdh> pid controlled spindle?
[19:19:11] <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

[19:25:32] <tjb1> Thats cool, my school office just pulled me out of a class
[19:25:56] <gene77> Lemme see how that looks. Thanks Andy
[19:26:44] <gene77> Thats a setp, can I use an arbitratry name there?
[19:28:25] <tjb1> Oh that class was cancelled because we didnt get enough students...
[19:28:35] <tjb1> Cool, now I am at 10 credits and a part time student
[19:31:39] <andypugh> gene77: I don't understand the question
[19:34:03] <gene77> first, where in the html docs for 2.5, is the manpage for comp, the comparator?
[19:35:58] <gene77> AKA the loadrt syntax for one copoy of it.
[19:36:32] <tjb1> Ah lovely, picking from classes that the whole school already scheduled
[19:37:11] <jdh> womens studies
[19:38:00] <gene77> Andy, I am trying to detect a stalled spindle fast enough to save the fuse.
[19:38:30] <tjb1> Boy the school really fucked me over now
[19:38:43] <jdh> what school is this?
[19:39:01] <gene77> So far I have "loadrt comp count=1" and "addf comp servo-thread:
[19:39:37] <tjb1> pct.edu
[19:40:33] <gene77> So next I need to take "pid.0.error" to one of the comp.0.input's I assume.

[19:41:34] <andypugh> (You will need to check the manpage to figure out which input it which)

[19:42:02] <andypugh> Actually, wcomp might be better if the error is bipolar.
[19:43:35] <gene77> And thats the manpage I can't find on line
[19:46:00] <tjb1> Hey jdh, tell your son about www.ratemyprofessors.com

[19:49:49] <jdh> that manpage?

[19:56:44] <gene77> if thats where they are supposed to be, they are all missing, so obviously that isn't the right path..
[19:58:13] <anonimas1> gene77: the best way is to run it off a cfd with a torque limit set and a error output
[19:58:26] <anonimas1> vfd..
[19:59:00] <anonimas1> nvm..
[19:59:03] <anonimas1> pid works too.
[20:01:16] <gene77> maybe, but I have a C41 and the OEM motor controller, call me cheap, its a mini-lathe

[20:01:54] <jdh> I kept blowing fuses in my 7x also
[20:02:55] <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.
[20:04:00] <jdh> I have a c41, the response is incredibly slow.
[20:07:20] <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
[20:07:43] <jdh> do you have the new one or old one?
[20:09:04] <gene77> The OEM controller went up in smoke, so its fresh, the C41 is about 3 months old.
[20:09:24] <jdh> does it have a 7805 in one corner?
[20:09:39] <gene77> I believe so.
[20:09:49] <jdh> that's the old one
[20:09:55] <jdh> new one is 5V only

[20:41:23] <uw> and if it does, just barely
[20:41:39] <jdh> yep
[20:41:50] <uw> hmm, so im not alone
[20:41:56] <jdh> turns it lightly black, but that scrapes off
[20:42:00] <uw> thats, reassuring
[20:42:15] <uw> yea i still see rust
[20:42:37] <uw> it says it's supposed to "convert" the rust to some phospous or whatever
[20:42:53] <jdh> iron phosphate
[20:43:05] <uw> ah thats it
[20:43:18] <uw> so, what are your methods for removing rust?
[20:43:22] <uw> if you have any?
[20:43:44] <jdh> mechanical removal
[20:44:16] <uw> but what about the hard to get areas? where even a sand blaster cant get?
[20:46:28] <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.
[20:47:14] <JT-Shop> gene77, yep loadrt comp count=1 <note no spaces iirc between count the = and 1
[20:47:46] <uw> i see. welp, out to try something else.
[20:47:46] <JT-Shop> gene77, and comp needs a floating point thread
[20:50:41] <JT-Shop> soak it in a strong solution of caustic soda to remove the iron oxide down to the steel
[20:51:06] <JT-Shop> note that caustic soda is not for the careless types

[23:06:09] <tjb1> You would have to activate it with a G4x anyway
[23:06:25] <tjb1> What is it…40, 41, 42?
[23:06:34] <andypugh> tjb1: So, you are adding a second parport?
[23:06:40] <tjb1> Yes andypugh
[23:06:41] <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
[23:07:20] <cradek> I can't see how using cutter comp for drilling makes much sense
[23:07:32] <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
[23:07:33] <cradek> you could drill inside the corners of a square I guess
[23:07:42] <tjb1> cradek: if cutter comp was activated when moving with a G01 command it would offset whichever direction correct?
[23:07:48] <andypugh> I don't see how it makes _any_ sense
[23:07:58] <Tom_itx> it's not supposed to
[23:08:26] <Tom_itx> i know it offsets the cutter based on the comp but does it affect linear z moves?
[23:08:41] <tjb1> No but it will affect the position
[23:09:02] <Tom_itx> i'm cutting some profiles then i was drilling a couple holes with the mill since they are the same size
[23:09:03] <tjb1> Just shut it off before moving there

[23:10:18] <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.
[23:10:37] <tjb1> Wow, 384
[23:10:49] <Tom_itx> tjb1, i'd sure go that route if it were me
[23:11:03] <tjb1> I wouldnt know what to do with 384 :)
[23:11:05] <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)
[23:11:25] <Tom_itx> cradek the only moves to the z is a rapid
[23:11:27] <cradek> ... you'll get one of them
[23:12:16] <cradek> Tom_itx: the direction of that before move is part of what determines the position. also the one after your Z move.

[23:19:41] <andypugh> taiden: Possibly.
[23:19:52] <taiden> i seem to remember a g2.1 or something starnge like that
[23:19:58] <andypugh> No, thinking harder, I don't think so
[23:19:59] <taiden> i can't seem to find it anymore though
[23:20:14] <atom1> firmware=hm2/7i43-4/SVST2_4_7I47B.BIT

[23:20:39] <taiden> i'm just trying to throw a quick facing operation into a gcode file i have going
[23:20:40] <Tom_itx> andy, is that it?
[23:20:42] <andypugh> I wondering about using polar coordinates, but that won't work.
[23:20:49] <andypugh> Tom_itx: Yes
[23:21:09] <Tom_itx> i thought that was just for the 7i47
[23:21:16] <Tom_itx> combo
[23:21:20] <Tom_itx> not the 2nd port
[23:21:26] <taiden> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?G12-13
[23:21:44] <jdh> yeah, that one.
[23:21:48] <andypugh> No, that is the 7i43 firmware. The 7i47 is a passive device
[23:22:20] <Tom_itx> i think all the stepper encoder stuff is on the first port though isn't it?
[23:22:40] <Tom_itx> i'll look in a bit. need to get tool tables working first
[23:22:42] <andypugh> taiden: You could add that with mhaberlers marvelous G-code remapping.
[23:22:56] <andypugh> Tom_itx: Give me a moment
[23:23:06] <jdh> [ 4979.591540] hm2/hm2_7i43.0: IO Pin 004 (P4-09): Encoder #0, pin A (Input)

[23:23:57] <andypugh> Not for the faint-hearted
[23:24:13] <atom1> i know
[23:24:42] <atom1> oh that wasn't for me
[23:25:36] <atom1> andy, dmesg shows the 2nd port all as gpio
[23:26:05] <andypugh> Tom_itx: You have 4 encoders there, I think.
[23:26:37] <atom1> i may have used those pins already
[23:26:41] <andypugh> Which pins of the other connector do you want an encoder on?
[23:27:11] <atom1> i'm not sure just yet
[23:27:23] <atom1> i need to look it over a bit more
[23:27:39] <atom1> i may be able to do it myself but i've never written or modded a bit file
[23:27:52] <atom1> i'm set up to do it
[23:28:33] <jdh> 7i47 was raised from birth to have encoders. You are trying to thwart its destiny.
[23:29:04] <atom1> jdh, i'm using one on it but i think i already used the other pins for gpio
[23:29:11] <atom1> i need to double check that
[23:29:36] <jdh> gpio is easy to move and you won't need the voltage divders on the other port
[23:29:36] <atom1> 4 6 and 8 are encoders
[23:29:58] <atom1> jdh, it's a single ended encoder from a printer
[23:30:07] <atom1> just an ir detector
[23:30:20] <atom1> for spindle speed
[23:30:25] <jdh> then you would still need them for that.
[23:30:43] <jdh> someday, I'll get mine mounted.
[23:31:44] <atom1> oh wait, i've only got one encoder loaded in the ini
[23:31:54] <atom1> i'm not sure what pins the 2nd one would fall on
[23:32:00] <andypugh> How many are you using?
[23:32:07] <atom1> ^^ was encoder 1
[23:32:10] <atom1> just one for my pendant
[23:32:34] <andypugh> There should be 4 on the 7i47
[23:32:47] <atom1> yeah but i wasn't using them so i only configured one
[23:33:04] <andypugh> So, why do you need an encoder on the second connector?
[23:33:29] <atom1> because i'm pretty sure i used the pins for something else already
[23:33:49] <atom1> i could move stuff around i suppose
[23:34:03] -!- tjb1 has quit [Quit: tjb1]
[23:34:03] <andypugh> Ah, so you want encoder 1 to be on the second connector, and only encoder.0 on the 7i47?
[23:34:10] <andypugh> That seems… perverse
[23:34:16] <atom1> just for convenience
[23:34:31] <atom1> heh
[23:34:35] <atom1> i'll work it out
[23:34:45] <atom1> i'll probably move the gpio
[23:35:15] <andypugh> No, I have already built you a custom firmware once, it't no more trouble to make it even stranger.
[23:35:26] <atom1> you did?
[23:35:51] <andypugh> Well, I stopped it 75% through just then
[23:35:57] <atom1> heh sorry
[23:36:09] <atom1> i'd rather just know how to do it
[23:36:43] <atom1> http://tom-itx.dyndns.org:81/~webpage/emc/xilinx/xilinx_install_index.php
[23:36:50] <atom1> you knew about that right?
[23:37:37] <atom1> doesn't cover modding the actual files
[23:39:21] <atom1> i'll have to set it up again as i've reloaded the hdd
[23:40:46] -!- taiden has quit [Quit: taiden]
[23:40:50] <andypugh> Well, I just made myself a firmware about an hour ago, so I was sort of in the groove
[23:41:52] <atom1> i will likely just enable one more on the 7i47 and move the io to the 2nd port on the 7i43
[23:44:26] <atom1> how do i bring up the tool touch off dialog? MDI a Tx M6 ?
[23:47:04] <andypugh> I don't think you can from G-code. You need to use the GUI button
[23:47:24] <atom1> touch off?
[23:47:35] <atom1> how do i select the tool then?
[23:48:01] -!- Thetawaves has quit [Quit: This computer has gone to sleep]
[23:48:35] <JT-Shop> for the touch off dialog you have to load the tool first with Tn M6 G43
[23:49:42] <atom1> how do i get the work offset dialog back then or is it a separate dialog?
[23:50:19] <JT-Shop> what do you mean?
[23:50:40] <atom1> i loaded Tx M6 G43, now what?
[23:51:03] <atom1> jogged to where i want it set
[23:51:27] <atom1> ok nevermind i see it
[23:51:30] <JT-Shop> setting the Z material height or the tool offset from some fixed point?
[23:51:38] <atom1> tool offset
[23:51:51] <atom1> T Tool Table from the menu
[23:52:08] <JT-Shop> tool offset from the material or a fixed point?
[23:52:13] <andypugh> Yes. Get it right this time, and keep your 100% record. It won't last.
[23:52:45] <atom1> material
[23:53:04] <atom1> andypugh, :)
[23:53:32] <andypugh> atom1: Getting an impenetrable error. So as you have a better solution, I am going to give up.
[23:53:38] <JT-Shop> then make sure the touchoff to workpiece is selected
[23:54:05] <JT-Shop> and touch off your G54 or whatever coordinate system
[23:54:20] <andypugh> Night all
[23:54:23] <atom1> andypugh, what was that in regard to?
[23:54:27] <JT-Shop> night
[23:54:30] <atom1> night
[23:54:38] <atom1> guess we'll never know
[23:54:40] <andypugh> Building the custom firmware you don't want any more
[23:54:49] <atom1> but... but...
[23:54:58] <andypugh> Go on..
[23:55:06] <atom1> i didn't really ask you to build it
[23:55:17] <andypugh> I know.
[23:55:22] <andypugh> I was showing off.
[23:55:37] <atom1> i'll build one and you can see if it looks right
[23:55:47] <atom1> maybe
[23:55:57] <atom1> now back to the tool table
