[00:16:40] <paul_liebenberg> Hello, I don't have the manual toolchange figured out yet. I have been chopping my gcode up into a different program for each tool and touching off in z each time. It seems I have to hit run each time, then stop and touch off and hit run again. If I touch off before I run the first time it will not work. Why and how do I fix? Thanks.

[00:18:35] <Tom_itx> paul_liebenberg do you have mulitple tool holders so you can preset the tools?
[00:19:13] <Tom_itx> i've got manual tool change set up in my configs: http://tom-itx.dyndns.org:81/~webpage/cnc/configs/sherline/
[00:19:28] -!- arekm [arekm!~arekm@pld-linux/arekm] has joined #linuxcnc
[00:19:45] <paul_liebenberg> well, I do - but I just have to finish this one job before I go there. Thanks, will go and look at the link.
[00:20:47] <Tom_itx> be aware i'm using a custom hal_manualtoolchange file there that uses an external button in addition to the one in the axis dialog box
[00:21:01] <Tom_itx> other than that it works the same
[00:21:50] <Tom_itx> should be in the sherline.hal file
[00:22:27] <Tom_itx> just comment out the net button-tool-change line
[00:22:33] <paul_liebenberg> Well as usual i am going to have to hit the books! i haven't really looked at hal files yet - i am very green!
[00:23:14] <Tom_itx> search for 'manualtoolchange' in the file and add those lines to yours

[00:23:44] <paul_liebenberg> ok, will do some testing. Thanks!\

[00:28:27] <JT-Shop> Tom_itx, wanna play with it?
[00:28:44] <atom1> haha cool
[00:29:30] <atom1> what are all the inputs for?
[00:29:58] <atom1> is this to write your custom hal?
[00:30:08] -!- sumpfralle has quit [Ping timeout: 265 seconds]
[00:30:18] <JT-Shop> cause the 7i76 has a lot of inputs
[00:30:32] <atom1> so does the 7i84
[00:31:04] <atom1> oh this is purely for the 5i25
[00:31:12] <JT-Shop> yea
[00:31:13] <atom1> etc
[00:31:23] <JT-Shop> if you want to mess with it I'll upload it
[00:31:29] <atom1> you tryin to get me to get one??
[00:31:40] <atom1> i'm workin on some xilinx stuff right now
[00:31:50] <atom1> trying to fix my tutorial and make a file
[00:32:00] <JT-Shop> no, just getting some program exercise
[00:32:03] <atom1> but i'll take a look
[00:32:04] <JT-Shop> programming
[00:32:11] <JT-Shop> ok, give me a moment
[00:32:24] <atom1> may not get to it tonight but who knows

[00:38:52] <jthornton> it has some pretty cool things and some are borked as I'm in the middle of changing my mind about things
[00:39:35] <jthornton> when you get time it would be interesting to get your overall opinion as for look and feel
[00:39:46] <Tom_itx> ok
[00:40:01] <Tom_itx> once i update xilinx with sp4 and clean house a bit i'll take a peek
[00:40:10] <jthornton> ok thanks
[00:40:27] <Tom_itx> unless it's past your bedtime :D
[00:40:31] <Tom_itx> by then...
[00:41:08] <jthornton> pretty much couch time... we just got back from our key west meeting and I'm full of beer and pizza
[00:41:24] <Tom_itx> yup, just had pizza here as well
[00:42:24] <jthornton> the file save and file open work and use an xml file to store the info

[00:59:38] <atom1> jthornton, what does the display type have to do with it?
[01:00:06] <jthornton> it changes in axis if it is a lathe
[01:00:30] <jthornton> I assume you mean Machine Type
[01:00:39] <atom1> some of it doesn't make sense since i don't have a 5i25
[01:01:06] <atom1> does the daughter card select the right bit file for it?
[01:01:10] <jthornton> some of it don't make sense to me either and I have 2 5i25's
[01:01:26] <jthornton> no a 5i25 does not use a bit file
[01:02:19] <pcw_home> you can actually use a 7I76 with a 5i20...
[01:02:49] <jthornton> with the cable adapter?
[01:03:00] <jthornton> 26-50 adapter
[01:03:05] <pcw_home> yeah we make one
[01:03:25] <jthornton> I saw that when I was cruising the new store today
[01:03:35] <jthornton> is the new store live?
[01:03:52] <atom1> looks live
[01:03:53] <pcw_home> yes
[01:04:14] <atom1> can't be memorex! they don't make it anymore :)
[01:04:33] <jthornton> needs more contrast in some of the colors :)
[01:04:49] <pcw_home> for setups that dont use GPIO all configs are pretty much the same (except the FPGA name)
[01:05:16] -!- Tom_L has quit []
[01:06:09] <atom1> care to see if this needs anything added / removed: http://tom-itx.dyndns.org:81/~webpage/emc/xilinx/xilinx92_install_index.php
[01:08:17] <Tom_itx> that's for the older boards
[01:09:50] -!- zumba_addict has quit [Ping timeout: 264 seconds]
[01:11:10] <pcw_home> Yeah looks great. you might add a note to the first link to point people to the 9.2 instructions if they have a 5I20/4I65
[01:11:30] <atom1> oh from the 14.5 page?
[01:12:08] <pcw_home> maybe on both
[01:12:34] <pcw_home> (if you have a XXX card: go here)

[01:32:54] <atom1> jthornton, what's the DB25P3 tab for?
[01:33:09] <atom1> is P2 different?
[01:33:43] <atom1> oh, yeah it's internal
[01:34:11] -!- mozmck [mozmck!~moses@client-67.210.159.209.dfwtx.partnershipbroadband.com] has joined #linuxcnc
[01:34:59] <atom1> so you get 33 io with the 5/6i25
[01:37:33] <atom1> jthornton, are you gonna allow entry to build a tool table?
[01:37:50] <atom1> with tool diameter etc?
[01:38:03] <jthornton> no, that can be done after
[01:38:20] <jthornton> lol it is already too complicated
[01:38:25] <atom1> why do you need a create tool table entry then?
[01:38:47] <jthornton> I'm not sure what you mean?
[01:38:55] <atom1> under the Config tab
[01:39:07] <atom1> you have a box to Create Tool Table

[01:39:20] <jthornton> you need to create a starter file
[01:39:31] <jthornton> then the tool editor can edit that
[01:39:41] <atom1> so it makes a blank file and an entry in the ini
[01:40:03] <jthornton> it has a little bit of sample data in it

[01:45:06] <jthornton> no, but close
[01:45:20] <atom1> 7i78 shows 7i77 daughter card
[01:45:57] <atom1> err wait...
[01:46:03] <atom1> how did i do that just now...
[01:46:05] <jthornton> get 5i25.0.1.1
[01:46:23] <jthornton> fixed a bunch of borked stuff like p2
[01:47:01] <jthornton> now it is couch time

[04:05:32] <skunkworks> the Matsuura MC-500V2 looks nice. yaskawa servos and drives
[04:05:46] <skunkworks> box wayss
[04:07:08] <Tom_itx> that sounds pretty rugged
[04:08:27] <Tom_itx> what collet size?
[04:11:48] <skunkworks> b235
[04:11:51] <skunkworks> heh
[04:11:53] <skunkworks> bt35
[04:12:49] <Tom_itx> so a bit smaller than CAT40 or 40 taper
[04:13:26] <Tom_itx> is BT a british standard/
[04:13:27] <Tom_itx> ?
[04:16:24] <skunkworks> no clue
[04:16:51] <skunkworks> have not looked at the standard. we have no tooling but seems like ebay has a lot of it
[04:16:59] <Tom_itx> looks like a 'smaller' but rigid machine
[04:17:09] <Tom_itx> 20 x 14 travel
[04:17:30] <Tom_itx> 17.7 z
[04:17:44] <skunkworks> yes
[04:17:57] <skunkworks> and chip/coolant control! :)
[04:18:41] <Tom_itx> nice
[04:19:04] <Tom_itx> do you have a shop?
[04:19:42] <skunkworks> 6000rpm Not 100% sure if it has encoders or resolvers
[04:19:48] <skunkworks> brushed servos
[04:21:32] <cradek> it's cool that it doesn't matter anymore (encoders vs resolvers)
[04:21:39] <skunkworks> right

[04:22:01] <skunkworks> cradek: what did your jr have for servos/drives?
[04:22:32] <skunkworks> Tom_itx: yes - looks like that. - 4th axis...
[04:22:37] <Tom_itx> decent rapids
[04:22:47] <Tom_itx> almost 600 ipm
[04:22:54] <skunkworks> z axis says it is 'only' 1100 watts..
[04:23:08] <Tom_itx> i saw another one with a 7hp spindle

[04:24:21] <Tom_itx> is that the 4th axis sticking out the front?
[04:24:37] <skunkworks> I think so
[04:24:40] <Tom_itx> that's kinda awkward
[04:26:01] <Tom_itx> 6k rpm is decent

[14:44:16] <Tom_itx> jthornton i would almost think so since you could have separate configs for each one
[14:45:06] <pcw_home> jthornton: the sserial_port_0=whatever may be different
[14:46:39] <jthornton> is the first X for p2 in sserial_port_0=0XXX
[14:46:49] <pcw_home> Though I think you can have a channel enabled but not present without serious problems
[14:47:15] <jthornton> like if you want mode 3 on p3 and mode 0 on p2 sserial_port_0=30XX
[14:48:13] <MattyMatt> are cards like the 7i80DB already running a soft core to handle the ethernet etc?
[14:49:19] <pcw_home> on the 7i76x2 they go
[14:49:20] <pcw_home> 0 P3 7I76_1 field I/O
[14:49:22] <pcw_home> 1 P3 7I76_1 expansion
[14:49:23] <pcw_home> 2 P2 7i76_2 field I/O
[14:49:25] <pcw_home> 3 P2 7I76_2 expansion
[14:49:54] <pcw_home> yes the 7I80/7I76E etc have a soft processor
[14:51:03] <pcw_home> (as does sserial host firmware and resolver firmware)
[14:53:27] <skunkworks> the ethernet interface with linuxcnc is about >||< close I feel...
[14:53:45] <pcw_home> the .pin file may be needed to figure out which sserial channel goes where
[14:55:25] <pcw_home> skunkworks: yeah I think so too (my test system has been running 3.5 weeks/24-7s now without a glitch)
[14:55:49] <Tom_itx> pcw_home, bitfiles for all other cards _but_ the 5I20 / 4I65 can be generated on xilinx 14+ ... is that fair to say?
[14:56:06] <Tom_itx> just confirming what i put on the site
[14:56:08] <pcw_home> Yes
[14:56:16] <Tom_itx> ok

[17:39:11] <MattyMatt> with spindle-synchronized motion, is there any advantage to a quadrature encoder over a simple index pulse, on a simple lathe for threading?
[17:39:47] <MattyMatt> simple lathe = no speed control (except by moving the belt)
[17:40:00] <MattyMatt> and the axis would be steppers
[17:40:15] -!- motioncontrol has quit [Quit: Sto andando via]
[17:40:28] <CaptHindsight> MattyMatt: index doesn't give you direction
[17:40:38] <MattyMatt> lathe only goes one way
[17:41:16] <MattyMatt> I'm just wondering if the co-ordination of more pulses per rev results in better threading
[17:41:20] <archivist> index and a sensible number of slots is ok
[17:42:14] <archivist> depends how bad/good your motor speed is, more pulses means it can follow the cutting load better
[17:42:44] <MattyMatt> ah right, that might be handy if my belt is slipping etc

[17:54:59] <eric_unterhausen> I'm sure the encoder they are using is dirt cheap
[17:55:11] <eric_unterhausen> 100 ppr encoders cost what, $5 at digikey?
[17:55:56] <MattyMatt> it'll be the detents that are crap or missing, I'd imagine
[17:56:29] <MattyMatt> compared to the $45 ones
[17:56:32] <CaptHindsight> depends on if anyone is making 35 cent detents or not

[18:17:14] <IchGuckLive> Loetmichel: tonight there has been 3-4 germany in here asking acording to the logs and ther nicks
[18:17:39] <CaptHindsight> do they make a MPG that reminds you to change the axis before cranking?
[18:17:41] <Loetmichel> you meant: germans?
[18:17:52] <IchGuckLive> ;-)
[18:17:58] <pcw_home> no the crashing noise reminds you
[18:18:28] <MattyMatt> have a jogwheel for each axis. etch-a-sketch style
[18:18:30] <Tom_itx> CaptHindsight how would it know what axis you had in mind?
[18:18:42] <IchGuckLive> ok on mpg with my mashines i agree to you i dont need them as i run on 5mm spaces
[18:19:00] <CaptHindsight> Tom_itx: it should read my mind of course

[18:20:36] <MattyMatt> or 3 laser beams that shine along the jog axis
[18:20:46] <Loetmichel> so if you crash usually nothing wors than a ruined workepiece happens
[18:21:06] <PetefromTn> You are not supposed to crash it LOL
[18:21:07] <MattyMatt> broken tool more often for me
[18:21:19] <CaptHindsight> MORI-SEIKI CNC LATHE SL-1A "WILL SHIP ITEM" as opposed to selling it and keeping it in place?
[18:21:19] <Loetmichel> ... but one time i welded the shaft of a 1/8" TC mill bit to the vice ;-)
[18:21:41] <PetefromTn> the SL1 is a nice older lathe..
[18:21:41] <IchGuckLive> oh there we are 12Nm stepeprs at 30:1 gear are able to break weldings at a crash
[18:21:51] <Loetmichel> friction welding happens FAST ;-)
[18:21:53] <Tom_itx> CaptHindsight maybe you could make a wearable pendant with accelerometers so when you nod your head it moves in that direction

[18:24:55] <IchGuckLive> PetefromTn: http://www.youtube.com/watch?v=s5_4S24dW8w and it works
[18:25:00] <MattyMatt> these $47 7" android tabs are almost small & cheap enough for a pendant
[18:25:35] <IchGuckLive> MattyMatt: tmart.com and with linux connection abality
[18:25:36] <CaptHindsight> MattyMatt: can't you just whip us up an app to run on our smartphones?
[18:25:51] <MattyMatt> hasn't anyone already?
[18:26:11] <IchGuckLive> there are android mach3 driving apps
[18:26:51] <IchGuckLive> but only nerds drive CNC with the smartphone
[18:27:00] <MattyMatt> ah yeah, axis on android would be nice. I've got one to run the reprap host
[18:27:19] <IchGuckLive> a 12hr 3D print on smartphone will fail im prett shure o.o
[18:27:33] <CaptHindsight> MattyMatt: use any android phone or tablet as the UI
[18:28:00] <MattyMatt> yeah that's what I got. the cheapest 7" tablet
[18:28:09] <MattyMatt> Allwinner A13
[18:28:16] <CaptHindsight> MattyMatt: allwinner yeah
[18:28:25] <IchGuckLive> yes i got them on all tractors A13 is good
[18:28:33] <MattyMatt> the A23 is only $2 more now
[18:28:37] <CaptHindsight> we are working on getting the cubieboard to host Linuxcnc right now
[18:28:43] <CaptHindsight> uses the a20
[18:28:46] <MattyMatt> same device, but dual core
[18:29:30] <CaptHindsight> in oem quan the allwinner soc's are all ~$6
[18:29:34] <MattyMatt> I hadn't considered running LinuxCNC core itelf on the tablet. no IO
[18:30:03] <CaptHindsight> yeah, it was my hope a few years ago when PCIe was poping up on ARM SOC's
[18:30:32] <MattyMatt> it has usbotg, so you could use an arduino for io I guess
[18:30:33] <CaptHindsight> now only imx6 and some Marvell have it
[18:30:41] <IchGuckLive> MattyMatt: via USB arduino 3D printing app
[18:30:49] <CaptHindsight> we looked at using SDIO as well
[18:31:36] <MattyMatt> when an arduino is the io, you might as well run reprap firmware, and the android just becomes the host/ui
[18:31:48] <IchGuckLive> hk shoudt make s shop and sell them a23 to us
[18:31:49] <CaptHindsight> after the udoo, cubie are working I might spin a board design to float around china
[18:32:05] <pcw_home> Probably better to use MachineKit on the RT portion
[18:32:31] <pcw_home> (when thats ready)
[18:33:17] <pcw_home> (and tablet for just userland parts)
[18:33:33] <CaptHindsight> if allwinner is going to start making boards now http://liliputing.com/2013/12/allwinner-a80-optimus-board.html
[18:33:38] <IchGuckLive> pcw_home: i stay with your stuff
[18:33:39] <MattyMatt> or a usb mesa card? :)
[18:33:59] <IchGuckLive> yesterday 2 more at full runing speed
[18:34:04] <CaptHindsight> it says dev board
[18:34:19] <pcw_home> USB is a dreadful industrial device interface
[18:34:38] <PetefromTn> IchGuckLive: video of that pendant is sweet man. Looks like a lot of work you put into it.
[18:34:47] <IchGuckLive> USB also can get kicked by the RT
[18:35:12] <MattyMatt> so android + 7i43 won't fly?
[18:35:18] <PetefromTn> how is that pendant hooked into linuxCNC?
[18:35:23] <IchGuckLive> PetefromTn: if you need 250+ f them Someone needs to do it
[18:35:46] <PetefromTn> you sold 250 of them?
[18:35:54] <IchGuckLive> PetefromTn: usb and python
[18:36:06] <PetefromTn> okay so wired uSB then.. Nice.
[18:36:15] <IchGuckLive> no i used them for education mashines only
[18:36:36] <pcw_home> no but android and BBB or Cubie or some other tiny embedded linux platform+machine kit
[18:36:49] <PetefromTn> It has onboard arduino.
[18:36:58] <IchGuckLive> yes
[18:37:07] <PetefromTn> you must have a LOT of educational machines.
[18:37:11] <MattyMatt> or raspi, if you can live with 17 io

[18:37:38] <IchGuckLive> PetefromTn: ;-)
[18:37:54] <pcw_home> raspi has SPI so can talk to a FPGA card
[18:38:11] <PetefromTn> Just finishing up a large built in cabinet job here this week. Gonna try to get back on the VMC work as much as possible.
[18:38:35] <PetefromTn> It has been kinda sitting there lonely for awhile now. Damn shame.
[18:38:46] <MattyMatt> Allwinner probably has SPI inside
[18:39:03] <CaptHindsight> maybe a $60 A80 board with FPGA?
[18:39:40] <IchGuckLive> A31 board is already working on spi
[18:39:54] <PetefromTn> what's SPI
[18:40:09] <CaptHindsight> how useful is an Udoo design (ARM + arduino + gpu to run a UI)?
[18:40:12] <IchGuckLive> communication line
[18:40:14] <pcw_home> Serial Peripheral Interface
[18:40:34] <PetefromTn> okay thanks.
[18:40:36] <CaptHindsight> IchGuckLive: which a31 board?
[18:41:09] <IchGuckLive> Allwinner A31 SoC
[18:41:14] <pcw_home> I think the serial baud rate may be an issue
[18:41:22] <pcw_home> (with udoo)
[18:41:24] <MattyMatt> A13 has 3x SPI
[18:41:38] <MattyMatt> dunno how many are used in this tablet
[18:41:48] <pcw_home> all capable of 100 mbits/sec
[18:42:08] <MattyMatt> none are on external ports, unless the SD is in SPI mode
[18:42:17] <CaptHindsight> MattyMatt: the problem is that most people won't want to solder to SPI pads (if they are even there) in a tablet

[18:42:53] <pcw_home> so far I can run HM2_SPI at 50 mbits/sec with FPGA --> FPGA so nearly the same as random PCI access
[18:42:56] <CaptHindsight> IchGuckLive: cubieboard uses the A20 and has SPI
[18:42:57] <MattyMatt> yeah I'm doing a dock on the reprap, so you can use either the tablet or a PC as the host
[18:43:07] <MattyMatt> via usb
[18:43:32] <MattyMatt> or remove the tablet to play angry birds
[18:44:00] <CaptHindsight> host or UI?
[18:44:05] <MattyMatt> both
[18:44:22] <CaptHindsight> oh, with repcrap
[18:44:28] <MattyMatt> arduino doesn't have ram to buffer the gcode, so it's fed from the host line by line
[18:44:56] <CaptHindsight> the printers that don't need a host that need a host
[18:45:35] <MattyMatt> tablet will sit on the front panel in a dock, at least you won't have trailing wires acting as antannae
[18:45:41] <eric_unterhausen> I was looking at bowden extruders today, nonplussed
[18:46:25] <MattyMatt> tablet also has wifi, so you can generate gcode on a pc, and send to tablet host

[18:54:36] <R2E4_> hi all
[18:55:09] <MattyMatt> if the A13 SoC is only $6, maybe it'd make more sense to make a new pcb with the same architecture & LCD as this tablet, but with a jogwheel, some IO, an SPI and a sturdy case
[18:55:39] <MattyMatt> complete controller in a box
[18:55:43] <CaptHindsight> allwinner soc with FPGA
[18:55:50] <MattyMatt> arr
[18:56:24] <MattyMatt> 50 pin facing the back
[18:56:36] <CaptHindsight> that's why we are currently using the cubie
[18:56:50] <MattyMatt> sweet
[18:57:11] <MattyMatt> does it have a big touchscreen lcd like a tablet?
[18:57:28] <CaptHindsight> maybe an allwinner + fpga + stepper drivers would be really handy
[18:57:44] <CaptHindsight> it has HDMI and supports 1080p
[18:58:22] -!- Komzpa has quit [Remote host closed the connection]
[18:58:34] <MattyMatt> stepper drivers on a single board is hard to service
[18:58:35] <CaptHindsight> you can play quake and open arena @30fps and >
[18:58:57] <MattyMatt> and hdmi needs an expensive TV
[18:59:36] <MattyMatt> and isn't touchscreen by default
[18:59:40] <CaptHindsight> has VGA and LCD out
[18:59:54] <CaptHindsight> I get what you're saying
[19:00:16] <CaptHindsight> I was hoping tablets would work out
[19:00:34] <MattyMatt> on the subject of stepper drivers, anyone tried the TB6600 ones?
[19:00:55] <MattyMatt> they look on paper like they've solved the issue the TB6560 had
[19:01:26] <MattyMatt> ^issues
[19:02:33] <CaptHindsight> I could float a tablet design that could have SPI at least on pads
[19:02:55] <CaptHindsight> but nobody would stuff them since it would be 2 cents lost profit
[19:03:26] <MattyMatt> I'm tempted to upgrade to these http://www.ebay.co.uk/itm/CNC-Single-1-One-Axis-TB6600-5A-Two-Phase-Hybrid-Stepper-Motor-Driver-Controller-/310833448162 from my 4 axis board
[19:03:49] <CaptHindsight> in China the manufacturers don't design much, they get a complete bom and files
[19:04:11] <CaptHindsight> so if they had a complete set of plans they would just copy/manufacture it
[19:04:55] <MattyMatt> if you could sell a batch at a profit before they do their own run, at least it would exist
[19:05:22] <R2E4_> I'm using mux4 count3 for mpg and scale select, but I cannot figure out how to use sel2, just sel0, sel1, I want to use three inputs into mux4. here is my hal file. LinuxCNC errors with sel2 does not exist.
[19:05:29] <R2E4_> AM I doing this wrong?
[19:05:59] <CaptHindsight> it would be a way to have tablets mass marketed with SPI all without them knowing or caring
[19:06:44] <jthornton> R2E4, please look at the truth table for mux4 http://linuxcnc.org/docs/html/man/man9/mux4.9.html
[19:07:35] <MattyMatt> I'd go the whole hog. add the 50 pin, jogwheel, and sturdy case, and let it become the generic machine controller. there must be (nearly) billions of cnc machines of one form or another now

[23:51:59] <owhite> greetings everyone. I'm running linuxcnc with a mesa 5i20 board and I'm trying to get a pwm output. I'm loading SVST8_4.BIT and my hal file is here: http://pastebin.ca/2560621 .
[23:52:10] <owhite> Once I start linuxcnc I checked the pins assigned to PWMGen #0 using dmesg, and I put my oscilloscope on that pin - but the signal just stays flat. Any suggestions?
[23:57:51] <skunkworks> the pwm channel has to be enabled...
[23:58:08] <owhite> checking the docs.
