[00:01:24] <tjb1> im just going to set search vel -
[00:02:03] <tjb1> It makes a TON of noise and vibration at 3 for search vel...
[00:02:48] <JT-Shop> does it search toward the switch with + or -?

[00:03:34] <JT-Shop> jp_: button box installed :) http://imagebin.org/229208
[00:04:04] <tjb1> +
[00:04:21] <JT-Shop> then they should all be +
[00:04:47] <JT-Shop> set the search - and it will go the other way
[00:04:49] <jp_> Good old AB 800T LOL
[00:04:54] <andypugh> JT-Shop: My machine searches on then latches off.
[00:05:24] -!- FinboySlick [FinboySlick!~shark@squal.net] has joined #linuxcnc
[00:06:10] <JT-Shop> that works too if you search at warp speed :)
[00:06:34] <JT-Shop> jp_: got a box full of the 800T's for free, I just had to strip them from a bunch of machines
[00:06:51] <jp_> JT-Shop, Thinking of selling my kitamura and just put a little bit more money into the knee mill
[00:07:10] <jp_> Yeah You cant kill those
[00:08:07] <JT-Shop> you have a kitamura VMC?
[00:08:13] <jp_> Yes
[00:08:46] <JT-Shop> cool, I like my old BP VMC all except the drives which suck
[00:09:22] <tjb1> Im hooking rack up now...
[00:09:47] <jp_> JT-Shop, You got rid of it?
[00:09:59] * JT-Shop is off to the cocina
[00:10:04] <JT-Shop> no, I still have it
[00:10:20] <JT-Shop> time to start dinner guys
[00:10:25] <JT-Shop> see you later

[00:17:00] <tjb1> Ok
[00:17:15] <tjb1> I hooked rack up and the homing sequence is not tripping the limit anymore…must of been me. Sorry
[00:17:36] <tjb1> Can someone please explain in words an idiot can understand what the Home and Home_Offset values do
[00:19:38] <andypugh> Home is the position that the carriage moves to after completing the homing process.
[00:20:02] <tjb1> So that is a value in inches
[00:20:05] <andypugh> Home offset is the offset from the switch to the zero-point of the axis.
[00:20:20] <tjb1> so 3 would be 3 inches away from switch trigger
[00:20:26] <jp_> no
[00:20:40] <andypugh> I wasn't kidding about random numbers you know, it's a load easier than trying to understand it.
[00:20:41] <jp_> 3 would be at the trigger point
[00:21:06] <tjb1> I tried random numbers but didnt get what I wanted :P
[00:21:21] <jp_> home offset is what you want the dro to read when it finds home
[00:21:27] <jp_> its arbitrary
[00:22:29] <tjb1> Ok if I set home offset -3.0
[00:22:32] <tjb1> and home to 0
[00:22:39] <tjb1> Home will be 3 inches away from switch trigger?
[00:22:54] <tjb1> Thats what I got from the integrator manual
[00:23:43] <jp_> yes
[00:24:01] <tjb1> Well it didnt move 3 inches from the trigger
[00:24:14] <jp_> what does the dro say
[00:24:28] <jp_> oh one sec
[00:24:28] <tjb1> when its finished it says 0
[00:24:47] <tjb1> I thought home offset was how many inches the trigger is away from the home you want
[00:25:56] <jp_> yes it is
[00:26:16] <jp_> sorry was just checking something else
[00:26:38] <jp_> set home offset to 3 and home to one and see what happens
[00:29:38] <JT-Shop> tjb1: you have a g540 iirc you might want to start with a bit lower vel of 5 and accel of 75
[00:30:31] <JT-Shop> After latching, LinuxCNC sets the joint coordinate of the current point to HOME_OFFSET.
[00:30:42] <JT-Shop> HOME
[00:30:42] <JT-Shop> The position that the joint will go to upon completion of the homing sequence.
[00:30:47] -!- jtr [jtr!~jtr@cpe-071-076-196-103.triad.res.rr.com] has joined #linuxcnc
[00:31:25] <JT-Shop> if HOME is 0 after the homing the dro will read 0
[00:32:16] <tjb1> So if offset is -3
[00:32:26] <tjb1> That means it thinks the switch is -3 inches from the home
[00:32:39] <tjb1> and then will move 3 inches and set the DRO to 0 if HOME is 0
[00:32:48] <JT-Shop> andypugh: does it matter how far you overtravel the home switch to use the opposite signs?
[00:32:49] <tjb1> I need to adjust my g540, thats why the motor sounds funny
[00:32:53] <JT-Shop> yes
[00:33:00] <JT-Shop> did you not tune the mid range?
[00:33:18] <tjb1> I thought CNCRP did that
[00:33:31] <JT-Shop> what is CNCRP?
[00:33:46] <tjb1> cncrouterparts
[00:33:52] <tjb1> I need to adjust the driver trim
[00:33:59] <tjb1> It has correct current set resistors
[00:34:18] <JT-Shop> I don't think you can set it outside of the machine
[00:34:21] <jp_> sorry Dyslexia kicking in on the home definition
[00:34:23] <JT-Shop> properly anyway
[00:34:41] <tjb1> The trim is a screw on the g540
[00:35:08] <JT-Shop> yes, you need to cruse at a certian rpm and that info is in the gecko manual
[00:35:20] <JT-Shop> and adjust for smoothest running

[00:39:02] <tjb1> Ive adjusted trim pot everywhere and it never matches the Y axis with same settings...
[00:39:07] <tjb1> I think one of the drives is messed up
[00:40:35] <andypugh> Play swapsies with drives and motors, see if the problem follows the drive or the motor.
[00:40:50] <andypugh> (you might need to loosen couplings to do that)
[00:41:51] <tjb1> I redid stepconf and the problem went away...
[00:42:02] <tjb1> Must of been another setting i was missng

[00:46:26] <tjb1> Well numbers for rack and pinion are messed up
[00:46:36] <tjb1> I have it in MDI set to .1 for each press
[00:46:43] <tjb1> Its only moving ~.031
[00:46:52] <jp_> scale is messed
[00:47:19] <jp_> what is your PD on the pinion
[00:48:02] <tjb1> 1
[00:48:23] <andypugh> Is it by any chance moving 0.031830988618379" per press?
[00:48:29] <tjb1> yes
[00:48:34] <jdh> heh
[00:48:50] <jp_> metric?
[00:48:52] <andypugh> Your scale is out by pi
[00:48:57] <jp_> ah
[00:49:06] <jp_> circumference is 3.14
[00:49:09] <tjb1> divide it by pi
[00:49:48] <andypugh> Right, time to log off. Back on sunday, not before.

[00:55:49] <jp_> Makes more sense 600 seemed low
[00:56:03] <jp_> do you know why it is that number
[00:56:22] <tjb1> I thought I had it calculated out correctly before
[00:56:30] <tjb1> But I didnt know teeth per inch of the rack
[00:57:04] <tjb1> But thats not a calculated number…I took the 600*pi and it was coming out .115 so I did .1/.115 and took that times 2000 and got the 1739
[00:57:08] <tjb1> So its probably not exact
[00:57:59] <jp_> Teeth per inch doesn't really matter
[00:58:01] <tjb1> What is the proper equation
[00:58:16] <jp_> PD of the pinion matters
[00:58:54] <tjb1> According to CNCRP its on a 1" pitch circle
[00:59:17] <jp_> yes use the PD to calculate circumference
[00:59:38] <jp_> thats how much the machine will travel in 1 rev
[00:59:50] <jp_> of the pinion
[00:59:53] -!- KimK [KimK!~Kim__@wsip-184-176-200-171.ks.ks.cox.net] has joined #linuxcnc
[00:59:56] <tjb1> if I use this input scale = 10steps/1.8degrees*360*(1/3.14) = 636
[01:00:13] <tjb1> oh...
[01:00:29] <tjb1> I need to take that number times the reduction 2.73 and I get 1736
[01:00:40] <jp_> so based on your pinion 1 rev is 3.14 inches
[01:01:11] <tjb1> 10/1.8*360*(1/3.14)*2.73
[01:01:34] <tjb1> =1738.85350318
[01:02:15] <jdh> 1737.97200821010337241053
[01:02:50] <tjb1> guess I should use proper pi
[01:05:29] <jp_> yes
[01:07:22] <tjb1> WOrking good now
[01:07:25] <tjb1> Time to set up the homing again

[01:20:04] <tjb1> Do any THCs support linuxcnc?
[01:21:18] <jp_> mesa has one
[01:21:44] <jp_> JT has wrote some good stuff on that
[01:22:45] <jp_> tjb1, have you got your gantry axis done yet
[01:22:49] <tjb1> That will work with a g540?
[01:22:58] <tjb1> Done as far as what?
[01:23:00] <tjb1> Its on :P
[01:23:10] <tjb1> I have to remake the homing switch bracket
[01:23:39] <jp_> have you got it setup/moving yet

[01:24:56] <MattyMatt> surely tooth pitch is the only thing that matters on a rack? then the number of teeth becomes key, not the PD
[01:26:04] <jdh> should work out the same shouldn't it?
[01:26:09] <MattyMatt> when the pinion turns 1 rev, the travel will be exactly (on average allowing for lash) the number of teeth along
[01:26:11] <tjb1> http://www.youtube.com/watch?v=pD3zaRatH5M
[01:26:14] <tjb1> There jp_
[01:26:35] <MattyMatt> yeah but no need to involve PI anywhere
[01:27:13] <jdh> I can type pi faster than I can count teeth.
[01:27:59] <jp_> No matter how you slice it it still comes down to PD
[01:28:20] <jp_> do the math however you like
[01:28:35] <jdh> echo "2000 / 3.14159 * 2.73" | bc -l
[01:28:40] <MattyMatt> the PD may be nominal, but the number of teeth is absolute
[01:28:57] <MattyMatt> and the pitch of the rack is easy to measure (with a ruler)
[01:29:27] -!- gmagno [gmagno!~gmagno@a213-22-30-249.cpe.netcabo.pt] has joined #linuxcnc
[01:29:33] <jdh> you have to measure the teeth on the pinion and the pitch of the rack, and hope the pitch evenly fits 1 inch
[01:29:38] <tjb1> My rack is 20pitch
[01:29:45] <tjb1> 22teeth on pinion
[01:30:34] <MattyMatt> so it's 1.1" per rev. easy
[01:31:14] <tjb1> and .8689xxxx revs per inch
[01:31:57] <tjb1> Why if I put in 2.73:1 for the pulley setup and .8689xxx does it not create the scale correctly
[01:32:24] <MattyMatt> microsteps?
[01:32:50] <tjb1> 10
[01:32:57] <tjb1> WHich I also entered into step conf
[01:33:31] <MattyMatt> so 2000*2.73 steps per rev?
[01:33:49] <tjb1> Where did you get that?
[01:34:04] <MattyMatt> 1.8 deg steppers = 200 steps/rev
[01:34:14] <MattyMatt> with 10 microsteps = 2000

[01:35:15] -!- JT-Shop has quit [Read error: Connection reset by peer]
[01:35:38] <tjb1> Then it needs 2000*revs per inch
[01:36:01] <MattyMatt> 2000*2.73 / 1.1
[01:36:16] <tjb1> The answer is 1737
[01:36:21] <tjb1> lol
[01:37:00] <jp_> survey says!!
[01:37:04] <tjb1> The formula is 10/1.8*360*(1/PI)*2.73
[01:37:08] <tjb1> http://linuxcnc.org/docs/EMC2_Integrator_Manual.pdf
[01:37:09] <tjb1> Page 21
[01:38:23] <MattyMatt> I make it 4963.6363 steps per inch
[01:39:23] <MattyMatt> I'd keep the 2.73 as a fraction in the calcs. if stuff is integers keep it that way until the final calc, is my way
[01:39:51] -!- tlab has quit [Quit: Leaving]
[01:40:46] <tjb1> Thats wrong
[01:41:06] <tjb1> It is 1737, I have tested it
[01:41:16] <tjb1> Tell it to move 1 inch and it moves 1 inch
[01:41:27] <MattyMatt> cool. happy to be of no help >:)
[01:41:37] <tjb1> I also found out why stepconf was doing it wrong
[01:41:46] <tjb1> Heh no problem :P
[01:41:59] <MattyMatt> I just thought I saw a familiar issue I hear a lot with belts
[01:42:44] <MattyMatt> toothed belts that is
[01:43:35] <jp_> They probably forgot to use the PD
[01:43:41] <jdh> heh
[01:43:54] <MattyMatt> people fret about nominal diameters of pulleys, when it's all down to belt pitch and number of teeth
[01:44:19] <MattyMatt> V belts sure you need the PD
[01:45:02] <MattyMatt> and then a coefficient for slippage :)
[01:45:16] <jp_> Never had and issue using PD
[01:47:34] <MattyMatt> whatever works :) btw a sharpie dot every 5th tooth makes counting the little buggers easier
[01:47:54] <jp_> lol just playing around
[01:48:33] <MattyMatt> nothing worse than getting magic eye when you're up to around 60 of 100
[01:48:49] <MattyMatt> left eye counts 60, right eye counts 61
[01:48:56] <jp_> that would suck
[01:49:09] <MattyMatt> sharpie dots ftw
[01:49:31] <jdh> or, just look at the invoice, use what it says.
[01:49:56] <MattyMatt> meh invoice says dead inkjet, and it was 144 tooth in the end

[02:09:00] <tjb1> RT?
[02:09:06] <jp_> Real time
[02:09:23] <tjb1> I had a very small program so it was running very fast
[02:09:43] <jp_> no I meant the interface with linuxcnc

[02:09:50] <tjb1> But it looks like I can use HAL
[02:10:14] <jp_> yes it it just might be a userspace thing
[02:10:19] <tjb1> I was going to have the arduino use 2 output pins
[02:10:22] <tjb1> Up or down
[02:10:33] <tjb1> Not have linuxcnc control voltage

[02:31:37] <tjb1> Thats not apples fault
[02:31:44] <tjb1> It is for releasing it but they didnt make that
[02:33:23] <tjb1> They bought some company that was working on 3d mapping
[02:33:25] <MattyMatt> that's the fault </google>
[02:33:53] <MattyMatt> they just bought the data from TomTom
[02:34:12] <MattyMatt> who were already famous for dodgy satnav data
[02:35:20] <MattyMatt> crowdsourced maps are the future. even google aren't gonna walk every footpath
[02:36:07] <jp_> crowdsource is pretty cool
[02:37:04] <MattyMatt> climb every mountain, ford every stream
[02:37:31] <MattyMatt> that's what you end up doing if you obey TomTom satnavs :D
[02:37:49] <jp_> MattyMatt, you use rack alot?
[02:38:12] <MattyMatt> jp_ no just belt, on repraps
[02:38:24] <jp_> thinking of cncing my lathe and using the original rack
[02:39:45] <MattyMatt> no reason not to
[02:39:49] <jp_> MattyMatt, Ah then 3mm vs 1.75 whats your take
[02:39:52] <archivist> far too much backlash in a lathes rack
[02:40:06] <jp_> Thats what i was worried about
[02:40:17] <MattyMatt> jp_ 3mm is cheaper. that's the upshot
[02:40:27] <jp_> I do have an alpha gear rack i can use
[02:40:43] <archivist> use its leadscrew
[02:42:36] <tjb1> MattyMatt: It wasnt from TomTom, they bought a company trying to start 3d mapping
[02:42:37] <jp_> Id have to redo the whole leadscrew arrangement
[02:42:47] <tjb1> Im having a problem with 7 for velocity
[02:43:02] <tjb1> I even put accel at 10 and its like as soon as it hits 400 ipm it throws an error
[02:43:07] <tjb1> but doesnt tell me the error
[02:43:20] <jp_> following error?
[02:44:24] -!- grummund has quit [Ping timeout: 244 seconds]
[02:44:37] <jp_> slow it down and then increase until you get errors then back it off a bit
[02:44:54] <tjb1> It just says "Joint 0 has error"
[02:45:16] <jp_> probably trying to step to fast
[02:46:09] <tjb1> JT has 7 for accel lol
[02:46:43] <jp_> but if his scale is different
[02:46:51] <jp_> And hardware is different
[02:47:15] <jp_> it's not a good comparison
[02:47:32] -!- adb has quit [Ping timeout: 245 seconds]
[02:47:32] <tjb1> Is there a way to see the errors?
[02:47:36] <tjb1> Its like the box isnt big enough
[02:47:46] <tjb1> I can hit like 325 but as soon as I let off the key it errors out
[02:47:59] <jp_> run it in terminal
[02:48:46] <tjb1> Care to explain :)
[02:49:31] <jp_> I know if i pushed my accel or max vel to high i would get following errors
[02:50:21] <jp_> open a terminal window and type linuxcnc
[02:51:00] <jp_> alarms will show up in the terminal window
[02:52:24] -!- FinboySlick has quit [Quit: Leaving.]
[02:52:29] <tjb1> error on axis 0, command number 133
[02:54:21] <jp_> cut you max vel and accel in half what happens?
[02:54:45] <tjb1> It will work
[02:54:56] <tjb1> I had it 5 and 125 and it worked
[02:54:58] <tjb1> 7 and 125 dont
[02:55:21] <jp_> you maxing out the stepgens
[02:55:35] <jdh> pport or real hardware?
[02:55:57] <jp_> G540 i think
[02:56:01] <tjb1> g540
[02:56:10] Tom_itx is now known as me
[02:56:10] <jdh> using pport, or mesa?
[02:56:23] me is now known as Tom_itx
[02:56:59] <tjb1> parellel
[02:57:24] <jdh> bummer.
[02:57:49] <tjb1> why
[02:57:51] <jp_> how is it at 6 max vel
[02:58:20] <tjb1> lemme check
[02:59:19] <jp_> if it works goto 6.25 the 6.5 then 6.75
[02:59:21] <jdh> can you increase stepgen_maxaccel?
[02:59:34] <tjb1> Moved like 2 inches and then errored out
[02:59:47] <tjb1> What is difference between stepgen max and max accel?
[03:00:16] <jp_> was it accelerating or at speed?
[03:01:00] -!- Keknom has quit [Quit: Leaving.]
[03:01:08] <tjb1> at speed
[03:03:23] <jp_> im not 100% sure but it sounds like your at the limit. is it ok at 5.5?
[03:04:02] <jdh> is your base_period high?
[03:05:24] <jp_> what did you set step lenght and other too
[03:05:55] <jp_> and did you run the latency test?
[03:06:05] <tjb1> base period and the others in ini?
[03:06:12] <jp_> yes
[03:08:36] <jp_> BASE_PERIOD is the heartbeat of your LinuxCNC computer.1 Every period, the software step generator decides if it is time
[03:08:36] <jp_> for another step pulse. A shorter period will allow you to generate more pulses per second, within limits. But if you go too short,your computer will spend so much time generating step pulses that everything else will slow to a crawl, or maybe even lock up.Latency and stepper drive requirements affect the shortest period you can use.
[03:08:49] <tjb1> emcmot - base period is 100000
[03:09:04] <jp_> The simplest way to avoid this problem is to choose a BASE_PERIOD that is the sum of the longest timing requirement of your
[03:09:04] <jp_> drive, and the worst case latency of your computer. This is not always the best choice. For example, if you are running a drive
[03:09:04] <jp_> with a 20 us direction signal hold time requirement, and your latency test said you have a maximum latency of 11 us , then if you
[03:09:04] <jp_> set the BASE_PERIOD to 20+11 = 31 us you get a not-so-nice 32,258 steps per second in one mode and 16,129 steps per second
[03:09:07] <jp_> in another mode

[03:20:19] <tjb1> yes
[03:20:24] <tjb1> That baseperiod changed everything

[03:21:05] <tjb1> Its a plasma cutter
[03:21:18] <jp_> no the baseperiod
[03:21:36] <jp_> think of the baseperiod as a scan cycle
[03:21:53] <jdh> 100,000 base period means it can only run at 10khz

[03:26:15] <tjb1> Its a 65" wide axis
[03:26:20] <tjb1> 250 for accel
[03:26:28] <jdh> so, 2 seconds for full travel
[03:27:02] <tjb1> 1800 ipm
[03:27:45] <tjb1> is about the limit
[03:27:48] <tjb1> Its stalling at 2100
[03:28:56] <tjb1> Actually it will run at 2100, was stalling at 2300
[03:30:22] <tjb1> Sorry 1920, had the max set at 2100 but axis at 1920

[22:14:44] <linux-cnc-bob> im using rhino cam to make gcode and the post generator gives a bit incompatible code, the error is "R clearance plane unspecified in cycle" this is for a G81 canned drilling cycle
[22:15:06] <linux-cnc-bob> the code is here: G81X2.875Y3.475Z0.4886F12.0
[22:15:26] <linux-cnc-bob> I guess it should look something like this instead: G81 X4 Y5 Z-0.6 R1.8 L3
[22:16:40] <linux-cnc-bob> anyone have a good post generator for rhino cam or know how to fix this error?

[22:32:53] <tjb1> or 289...

[22:51:12] <Anon3776> Hello, I'm trying to set up a CNC lathe using a stepper motor to power the spindle. I have edited the .hal file to control the stepper motor (which is connected via step/dir signals) using the normal M3/4 S etc commands. I can't work out how to use it for threading - i.e. G33 and or G73.
[22:51:31] <tjb1> I meant on rhinocam
[22:52:07] <linux-cnc-bob> I did a search once for a rhinocam to linux cnc post processor but didnt see one
[22:52:20] <linux-cnc-bob> I just modified the existing bridgeport one that is in rhinocam

[22:54:39] <tjb1> try that one ^ and see if it adds spaces

[22:54:59] <tjb1> Your current one is stupidly hard to read :)
[22:55:04] <linux-cnc-bob> k
[22:55:22] <tjb1> Youll thank yourself if you ever have to search through it
[22:55:50] <linux-cnc-bob> so where does the 0.1 come from? I gues that is set in linux cnc
[22:55:53] <linux-cnc-bob> for R
[22:55:56] <tjb1> No
[22:56:03] <linux-cnc-bob> sorry meant rhino
[22:56:04] <tjb1> That should of been set when you made the toolpath
[22:56:12] <linux-cnc-bob> ya i think I remember seeing that
[22:56:24] <tjb1> Do you know what R is?
[22:57:07] <tjb1> I dont know how linuxcnc is going to read that
[22:57:17] <tjb1> I think it also requires a G98 or G99 in that line
[22:57:28] <tjb1> atleast Haas does

[23:09:18] <linux-cnc-bob> cya
[23:09:21] <tjb1> G98 will make it return to the Z before the G81 starts
[23:09:28] <tjb1> G99 returns it to the R value in the G81 line

[23:38:30] <Nick001-Shop> Will upgrading Axis 2.5.0 Pre 2-626 to current 2.5.1 do anything to a comp that runs good now? And how do I go backwards if it screws up?

[23:50:25] <linux-cnc-bob> I think for the R it is incorrect, if I put 0.1 for R then it will drop down 0.1 after drilling a hole and then Z will go back up 0.1 as it traverses to the next hole to drill
