[00:10:28] <JT-Shop> I was hoping to use the ELO drivers so the calibration thing works
[00:10:36] <AR__> ELO is a great band
[00:10:48] <Tom_itx> JT-Shop, can you explain about G96 and 95?
[00:11:06] <Tom_itx> i noticed andy used both in one file but only G96 in another
[00:11:09] <JT-Shop> Tom_itx: more than the manual does?
[00:11:17] <Tom_itx> i read it
[00:11:23] <Tom_itx> but why would you use both?
[00:11:36] <JT-Shop> two different things
[00:11:39] <Tom_itx> do you use G96 for most stuff?
[00:12:03] <JT-Shop> I use it for turning but not drilling or tapping
[00:12:09] <Tom_itx> G96 has more to do with the part diameter right?
[00:12:21] <Tom_itx> smaller it gets the faster the spindle turns
[00:12:26] <JT-Shop> yep
[00:12:32] <Tom_itx> where G95 moves the tool faster or slower
[00:12:36] <JT-Shop> constant surface speed
[00:12:39] <Tom_itx> right
[00:12:51] <Tom_itx> but that would affect the feed wouldn't it?
[00:12:53] <JT-Shop> G95 is how much you take per rev
[00:13:00] <Tom_itx> yeah
[00:13:10] <Tom_itx> how much do you usually take with aluminum?
[00:13:17] <Tom_itx> like .04
[00:13:18] <Tom_itx> ?
[00:13:25] <Tom_itx> well maybe more than that
[00:13:25] <JT-Shop> say you want to cut 0.25 per rev then G95 is easier than calculating the feed to get that result
[00:13:42] <JT-Shop> just depends on the part geometry
[00:13:50] <Tom_itx> i'm thinking thousandths per tooth like you would on a mill
[00:13:53] <Tom_itx> chip load
[00:13:59] <JT-Shop> yea, same thing
[00:14:06] <r00t4rd3d> http://i.imgur.com/U6KeoAu.jpg
[00:14:16] <Tom_itx> so .04 is a fairly light cut?
[00:14:18] <r00t4rd3d> im the local wood urn guy
[00:14:38] <r00t4rd3d> kinda creept
[00:14:40] <r00t4rd3d> creepy
[00:14:56] <Tom_itx> JT-Shop, what surface speed do you shoot for on aluminum?

[00:21:11] <Tom_itx> JT-Shop-2, what surface speed do you shoot for on aluminum?
[00:21:31] <JT-Shop-2> 200-400 on the lathe
[00:21:44] <JT-Shop-2> my internet is flaky during the rain
[00:21:46] <Tom_itx> k, so my 300 wasn't too outrageous
[00:21:52] <JT-Shop-2> no
[00:21:56] <Tom_itx> i realize the .15 was now that i see what it did
[00:21:58] JT-Shop-2 is now known as JT-Shop
[00:22:07] <Tom_itx> for the G95
[00:22:25] <Tom_itx> that should be down around a chip load feed rate right?
[00:23:33] <JT-Shop> G95 F0.150 might be too much load for
[00:23:38] <JT-Shop> Andys lathe
[00:23:48] <Tom_itx> i changed that to .015
[00:24:03] <Tom_itx> i plan to let him adjust that
[00:24:23] <Tom_itx> it's been too long since i ran the okuma
[00:24:30] <Tom_itx> i can't remember that stuff
[00:24:55] <Tom_itx> i do still have the pocket reference for it
[00:26:13] <Tom_itx> i know we had to limit the spindle speed with the bar feeder attached :D
[00:29:28] <JT-Shop> sounds like "you must whip it"
[00:29:49] <Tom_itx> i think they pulled the tail mount out of the floor once
[00:29:56] <Tom_itx> i wasn't there when it happened
[00:30:48] <JT-Shop> you getting the rain?
[00:30:57] <Tom_itx> no not yet
[00:31:03] <Tom_itx> sure was windy today though
[00:31:12] <Tom_itx> started out of the south and ended up out of the north
[00:31:38] <Tom_itx> i don't remember what rain is
[00:32:12] <Tom_itx> you can walk across the arkansas
[00:32:30] <JT-Shop> we have been wet all winter
[00:32:41] <Tom_itx> we need it for the wheat

[00:42:44] <JT-Shop> cool
[00:43:29] <JT-Shop> will it print rigatony?
[00:43:53] <tjb1> rigatony?
[00:44:31] <JT-Shop> sorry misspelled it is rigatoni
[00:44:39] <Tom_itx> JT-Shop, what code do you use for tapping?
[00:45:01] <tjb1> No it wont print pasta
[00:45:34] <JT-Shop> G33.1 I think
[00:46:02] <Tom_itx> sync motion
[00:46:08] -!- tayy has quit [Remote host closed the connection]
[00:46:19] <JT-Shop> yep G33.1
[00:46:39] <JT-Shop> tjb1: why not?
[00:46:58] <Tom_itx> so your z would be the thread pitch
[00:47:52] <Tom_itx> or is it divided by k
[00:48:14] <Tom_itx> i need a lathe to play with

[00:51:28] <Tom_itx> i see that now
[00:51:50] <Tom_itx> i'm not sure my cam would calculate that right
[00:52:13] <Tom_itx> i'll check the canned cycle part later
[00:53:01] <Tom_itx> what do you use to back a tap out of the hole then?

[02:32:24] <Tom_itx> G codes don't seem to be very standard
[02:32:34] <jdh> they mostly start with G
[02:32:49] <Tom_itx> G76 in my fadal book is fine boring
[02:33:06] <Tom_itx> and it's a thread cycle in lcnc
[02:34:01] <Tom_itx> the post is pretty liberal on how you can define the cycle though
[02:34:39] <Tom_itx> thread pass only, thread pass with rapid, or single command generates entire thread cycle
[02:40:15] <AR__> i rigid tap only without tapping head
[02:41:28] <Tom_itx> using G33.1?
[02:41:47] <AR__> using G00 Z-5
[02:43:52] <skunkworks> Tom_itx: both?
[02:46:57] <Tom_itx> looks like i could do single point several ways with this cam
[02:49:01] <Tom_itx> it would be hard to set up without a lathe though
[02:49:09] <jdh> buy a lathe!
[02:49:13] <Tom_itx> heh
[02:49:15] <AR__> build a lathe
[02:49:21] <AR__> use mill as lathe

[03:43:51] <Jymmm> "Everyone knows you can use a knife to cut things with, But to be able to fully utilize the potential of a knife for such things like carving a piece of wood into an animal requires prior knowledge and skill"
[03:45:13] <Valen> http://laughingsquid.com/wp-content/uploads/EcceHomo.jpg
[03:45:16] <Valen> paint brush
[03:45:49] <Jymmm> Oh, I read about that. sad
[03:46:44] <Jymmm> Valen: I like paint brush, that's pretty universal
[03:46:55] <Valen> rather more than a knife i think
[03:47:13] <Jymmm> Yeah, I think so too.
[03:47:35] <Jymmm> I was trying to avoid "tools" as many never touch em.
[03:48:00] <Valen> wrong room for that
[03:48:03] <Jymmm> But even in pre-school they are exposed to paint brudh
[03:48:39] <Jymmm> Valen: Yeah, well, I thought someone out the might have a life beyond #emc =)

[03:49:09] <Valen> yay how many internets do i win?
[03:49:21] <Jymmm> all of them!
[03:49:49] <Jymmm> te other one I thought of is a sharpening stone.
[03:50:32] <Jymmm> Valen: Thanks for the paint brush, that's perfect!
[03:50:57] <Valen> hah nobody uses stones anymore
[03:50:57] <Jymmm> Valen: WTH man, that's two you've come up with in the last month =)
[03:51:10] <Valen> I am a friggin rocket scientist you know
[03:51:16] <Jymmm> lol
[03:51:22] <Jymmm> Valen: what do you use?
[03:52:00] <Valen> I use a diamond lap, but i meant nobody uses stones to sharpen knives, its always some $24.99 ginsu plastic hunk of crap
[03:53:07] <Jymmm> Oh. Yeah I use stones, but I'm REALLY liking my pencil diamond sharpeners, and I'm looking into the belt sanders
[03:53:36] <Jymmm> The Buck Knives one I like a lot
[03:53:37] <Valen> I want to get one of those things that hold the knife at the right angle
[03:54:01] <Valen> for use on a flat stonr
[03:54:09] <Jymmm> Valen: I did at one time too, but it
[03:54:21] <Jymmm> 's just not for me being practical
[03:54:48] <Valen> I figured it'd do a better job than i would by eye
[03:54:57] <Valen> just for the kitchen
[03:55:26] <Jymmm> I have found that with little effort on my part the pencil works great for tossing an edge on a dull blade
[03:55:47] <Jymmm> I even sharpened my kukri with one surprisingly
[03:56:03] <Jymmm> (cold Steel kukti machete
[03:56:05] <Jymmm> )
[03:56:10] <Valen> oh I can make it sharp with the lap by hand
[03:56:20] <Valen> i just wanted it to be *really* sharp
[03:56:29] <Valen> like properly ;->
[03:56:53] <Jymmm> My kukri is! I thought I needed to sharpener it a LOT more, till it cut me yesterday
[03:57:06] <Jymmm> I barely touched it too!
[03:58:19] <Jymmm> Valen: I think learning the angles by hand is better than those V stones
[03:59:00] <Jymmm> Valen: only exception is a straight razor

[04:00:02] <Jymmm> those V sticks
[04:00:20] <Valen> nope its a thing you clamp the blade in it and pass it over the stone
[04:00:35] <Jymmm> Oh , THAT!
[04:01:29] <Jymmm> Valen: Yeah, I understand. *I* am just a purist in that respect. I want to learn/do it old-school ways in case I dont have this or that gadget available.
[04:03:39] <Valen> I figure my skill is good enough to do any job i want, but a magic whatsit can do a better job than I can ;->

[15:03:24] <Loetmichel> r00t4rd3d: if they are nt flinching yu are t cheap :-)
[15:03:32] <L84Supper> $150 for a custom etched coffin is a pretty low price in the US
[15:03:55] <r00t4rd3d> compared to a headstone and plot, i guess
[15:05:59] <L84Supper> IIRC that's about what they charge per letter on a headstone
[15:08:04] <Loetmichel> a tmbstone (typically granite over here) is a BIT harder to engrave than wood ;-)
[15:08:52] <r00t4rd3d> they sand blast them here
[15:08:58] <L84Supper> pretty much all done by CNC here
[15:09:13] <L84Supper> and ^^

[15:44:54] <pcw_home> joint 0 following error is expected on a first time servo setup
[15:45:50] <JesusAlos> How resolve?
[15:46:00] <Loetmichel> i go thje opposite route... just ordered 60 300uF 300V caps for a coil gun ;-)
[15:46:01] <JesusAlos> http://imagebin.org/247280
[15:46:44] <Loetmichel> ... -> projectile without the bang :-)
[15:47:07] <pcw_home> you need first verify that you have feedback in the correct direction and then tune each axis
[15:48:20] <JesusAlos> I configurate Z axis, but don't have Z servo
[15:48:26] <JesusAlos> only XY axis
[15:48:30] <pcw_home> (assuming that you have previously verified that you can enable and move the servos with the analog output)
[15:49:57] <pcw_home> your error is X (joint 0 is normally X)
[15:50:10] <pcw_home> in X I should say
[15:50:43] <JesusAlos> ok
[15:51:04] <pcw_home> are the motor drives configured for analog velocity mode?
[15:52:23] <JesusAlos> yes
[15:52:28] <pcw_home> you can check this with pncconf's open loop test
[15:52:47] <JesusAlos> the X servo loop test only run in - no in +
[15:52:59] <JesusAlos> and the speed is low
[15:53:18] <JesusAlos> I can't increase the Fast Dac Sped

[15:54:34] -!- zzolo has quit [Read error: No route to host]
[15:55:29] <pcw_home> if the drive speed is not symmetrical with + and - inputs its a drive fault or perhaps a drive setup error
[15:55:31] <pcw_home> if the 7I77 analog out is not symmetrical with +10 and -10 commands its a 7I77 fault or perhaps a wiring error

[16:01:30] <pcw_home> With this kind of problem its good to check one thing at a time
[16:01:32] <pcw_home> to check the drive by itself, _disconnect_ the drive from the 7I77,
[16:01:34] <pcw_home> enable the drive manually (by shorting the wires that went to the 7I77s ENA+ and ENA-
[16:01:35] <pcw_home> pins) and apply a small voltage (a 1.5V battery is good here) to the analog input pins
[16:01:37] <pcw_home> of the motor drive and see if the motor /axis move in either direction with equal speeds
[16:01:37] -!- chopper79 has quit [Quit: Leaving.]
[16:01:38] <pcw_home> when you reverse the battery leads
[16:04:06] <JesusAlos> 7i77 x axis output 0,1V in - direction and 0,05V in + direction
[16:04:25] <JesusAlos> in Y axis 10V in - and 10 in +
[16:04:50] -!- wildbilldonovan has quit [Quit: EOT]
[16:05:03] <pcw_home> is that disconnected from the drive?
[16:05:14] <JesusAlos> is conected
[16:05:31] <JesusAlos> is the supply of 7i77 to device
[16:05:39] <pcw_home> is this with the open loop test?
[16:05:50] <JesusAlos> when push + putton in test loop
[16:06:08] <JesusAlos> yes
[16:06:15] <JesusAlos> with open loop test
[16:06:28] <pcw_home> try with the drive disconnected
[16:06:40] <pcw_home> maybe its a wiring error
[16:06:59] <JesusAlos> ok
[16:07:07] <JesusAlos> can desconected in hot?
[16:09:36] <JesusAlos> yes is wiring conection
[16:09:44] <JesusAlos> al reves
[16:10:03] <JesusAlos> backwards + -
[16:10:24] <pcw_home> Ahh that would short out the X analog out
[16:10:51] <JesusAlos> now error joint 1
[16:11:07] <JesusAlos> it runs ok in open loop

[16:13:50] <pcw_home> So now you need to check if the feedback is in the proper direction
[16:13:52] <pcw_home> is this a inch or mm machine?
[16:15:57] <JesusAlos> mm
[16:16:17] <JesusAlos> I try with both encoder direction
[16:18:01] <pcw_home> usually you get encoder direction correct first (so DRO reads correctly) and
[16:18:03] <pcw_home> _then_ you change the feedback polarity on the output
[16:18:20] <pcw_home> (for proper negative feedback)
[16:20:05] <pcw_home> you will probably need to loosen the ferror limits for initial tuning (set ferror and min-ferror to say 25mm)
[16:20:07] <pcw_home> so you can see whats going on before you get a following error
[16:23:00] firephoto_ is now known as firephoto
[16:27:52] <pcw_home> After you get the encoders reading with the with correct scale and direction and the
[16:27:54] <pcw_home> feedback direction correct, John Thornton has a very nice velocity mode servo tuning tutorial here:

[18:34:27] <Loetmichel> okj, that is a bit of a challenge ;-)
[18:34:31] <Loetmichel> meant
[18:34:34] <L84Supper> yes, for real time control :)
[18:35:23] <Loetmichel> if you look inside a Tablet: should be possibnle to get some GPio out: http://www.cyrom.org/palbum/main.php?g2_itemId=11873
[18:36:17] <L84Supper> they generally don't route any, the pads are just left open
[18:36:53] <Loetmichel> but i would rahter use a cheap PC mini.itx board with W-Lan and then remote control the Board via network by the tablet
[18:36:57] <L84Supper> but if you find a tablet with GPIO please let me know

[22:36:31] <skunkworks> all of them
[22:36:36] <Jensor> ok
[22:38:32] <JT-Shop> Guess I should have explained just a bit more. There is tandem motors on the Y axis. When homing the machine will go until the Y1 side is on the limit then it waits for the Y2 side to catch up. This will square the gantry every time you home the machine. In parallel port I can do this but I can not find an effective wat to do it with the MESA boards.
[22:38:32] <JT-Shop> <chopper79> Since I do not have direct control of the stepgen using the MESa boards like I do with a parallel port
[22:38:32] <JT-Shop> <JT-Shop> best to ask on #linuxcnc channel

[23:42:22] <JT-Shop> looks good
[23:42:28] <Jymmm> lol
[23:42:44] <Jymmm> Then I think you need a 6" end plate too =)
[23:42:48] <Jymmm> 6" THICK
[23:42:56] <JT-Shop> lol

[23:43:25] <Jymmm> Oh, and \o/ 'V' guides
[23:43:43] <Jymmm> tilt up ones
[23:43:53] <JT-Shop> ?
[23:43:53] <Jymmm> spring loaded both UP and DOWN
[23:44:27] <Jymmm> JT-Shop: Cross cut view --> \o/ where the o is the log
[23:44:42] <Jymmm> hang on...
[23:45:27] <JT-Shop> http://imagebin.org/247351
[23:46:06] <Jymmm> .. \o/ <--- The 'o' is a log
[23:46:06] <Jymmm> .. I <--- I Beam
[23:46:16] <JT-Shop> http://imagebin.org/247352
[23:46:40] <JT-Shop> it is a vertical
[23:47:08] <Jymmm> for storage?
[23:47:17] <Jymmm> for storage/transport?
[23:48:06] <JT-Shop> v for splitting and store h for road
[23:48:36] <JT-Shop> left handnly woody sleeping on right
[23:48:37] <Jymmm> I still say have the fold down 'V' Guides just to prevent the log from going anywhere
[23:49:31] <Jymmm> maybe like those bank deposit hoppers... roll left load and split, roll right drop in pile
[23:49:47] <Jymmm> left load, center split, right drop
[23:50:34] <chopper79> Has anybody used the 5I25 with tandem motors on a single axis and used it to square the gantry during homing? Might not be the right question, but its a start.
[23:50:35] <JT-Shop> may work with perfect logs

[23:51:24] <JT-Shop> chopper79: pastebit your hal
[23:53:11] <chopper79> This is my current hal I use for my parallel port setup. I am converting to the 5I25 and need to perform the same logic as in the paralle port. the fact that I do not have use of step and direction signals in the .hal for the 5I25 config is making this very difficult to pass it correctly. Here is my current .hal that I use on the parallel port. http://pastebin.com/4k5dD0rM
[23:53:36] <chopper79> Not use of but control of the step and direction pins in .hal
[23:55:36] -!- ravenlock has quit [Ping timeout: 240 seconds]
[23:57:14] <chopper79> The logic I wrote in this will allow tandem motors on my Y axis controlled from just the Y stepgen functions. This allows me to use one key to move both motors and also allows me to square the machine on homing. I am having a tough time converting this logic over to the 5I25 configuration im working on. With no way to utilize the step and direction signals is what is making this difficult or me to figure out.

[23:59:09] <chopper79> It was suggested to use just the enable signal for the Y axis and then break it out to another stepgen (A axis) to gain the same fucntionality. It sounds correct but nothing is allowing me to correctly make it function as it did with a parallel port
[23:59:48] <chopper79> using and, or, not gate to do the breakout
