01:04 AM Deejay: moin
01:32 AM -!- #linuxcnc mode set to +v by ChanServ
01:47 AM mrec: what is halui is-auto for?
01:48 AM mrec: it somewhat messes up the start / pause button on the pendant I'd like to know the background of that flag
02:55 AM mrec: ok bug solved there are 2 issues in the xhc driver, does anyone use the xhc pendant who can test?
03:51 AM Tom_L: halui.mode.auto bit in
03:51 AM Tom_L: pin for requesting auto mode
03:51 AM Tom_L: halui.mode.is-auto bit out
03:51 AM Tom_L: pin for auto mode is on
03:51 AM Tom_L: morning
03:54 AM XXCoder: hey
04:12 AM mrec: does backlash compensation work with linuxcnc? I just had a look at it and it seems like it doesn't
04:13 AM mrec: just use BACKLASH in axis_N and take care that STEPGEN MAXACCEL is at least twice as big as STEPGEN_MAXACCEL..
04:13 AM mrec: well that's not doing anything
04:13 AM mrec: joint.0.motor-pos-cmd => stepgen.0.position-cmd is supposed to handle that no?
05:02 AM mrec: ok the forum is just confusing at many places people write that it should be put into AXIS_N no it should go into JOINT_N
05:10 AM Deejay: re
05:27 AM mrec: does anyone know why the pendant cannot jog beyond the initial limit while the keyboard can?
05:36 AM JT-Cave: morning
05:37 AM XXCoder: yo
05:37 AM XXCoder: mrec: sadly dont know much about that
05:41 AM mrec: I'd like to drive the home position and home via the pendant... however I can't get beyond the limit
05:41 AM mrec: well I'll check it another time... today 3 linuxcnc issues are solved, backlash and 2 pendant driver issues at least
05:41 AM XXCoder: nice
07:42 AM -!- #linuxcnc mode set to +o by ChanServ
07:47 AM Tom_L: mrec, once it is homed, it will stop at the limit you set
07:50 AM JT-Cave: I assume he means before homing
07:52 AM mrec: it's before homing yes
07:53 AM mrec: https://forum.linuxcnc.org/24-hal-components/42740-xhc-whb04b-4-6-issues?start=10#212109
07:58 AM mrec: I think I'm getting some idea about it
07:59 AM mrec: the pendant driver might possibly do the check and avoid running out of the boundaries
08:00 AM mrec: but it also locks the option to freely move with the keyboard (outside of the limits)
09:08 AM selroc: hi
09:13 AM selroc: whats up? everbody is sleeping?
09:13 AM JT-Shop: cleaning chicken shit here
09:16 AM selroc: not sure this is the right place, I have a very good offer to make for machinists
09:16 AM JT-Shop: actually that chore is done, now I'm sifting blasting media before it gets too hot
09:17 AM roycroft: it's going to rain again today here
09:17 AM roycroft: then summer returns
09:17 AM selroc: maybe somebody is interested to buy some CNC hardware
09:29 AM JT-Shop: https://forum.linuxcnc.org/54-user-exchange
09:30 AM selroc: thanks JT , I need to subscribe to the forum then
10:44 AM * roycroft wonders how his imac can be using 28GB of ram after he's shut down all apps except for xquartz
10:45 AM roycroft: i've run x11 on a 386sx with 4MB of ram before
10:45 AM roycroft: how did things get so bloated?
10:50 AM cloudevil: Practice.
11:14 AM * roycroft blames rms, again
11:24 AM Bleepshop: roycroft: They started teaching people to write C/C++ instead of ASM ? You could do shit on a 386 with 4mb in straight ASM that would require a 486 w/ 8mb to run in C...
11:26 AM * Bleepshop fondly remembers the day of using RAMDISK and loading all of Doom or Quake to be able to whomp ass on the localnet...
11:27 AM roycroft: that's really not it, bleepshop
11:27 AM roycroft: x11 was always written in c
11:28 AM JT-Cave: todays lumber report from HD 2x12x16PT $100 landscape timbers $4.37
11:28 AM roycroft: the problem is that rms worked at a uni, and decided that since hardware was free and unlimited to him, it was free and unlimited for everyone, and less valuable than programmer time, so he promoted writing bloated, crappy code with the gnu project
11:30 AM Jym: JT-Cave: eeeesh
11:30 AM roycroft: i don't use pt wood, so i have no idea what pricing is on that stuff
11:31 AM roycroft: but i bought some 2x12x16 fir boards a while back, and they were more like $25 each
11:31 AM Bleepshop: JT-Cave: $100 + tax for a pressure treated, 16' 2x12 ???
11:31 AM roycroft: "sales tax"
11:31 AM roycroft: what a quaint idea
11:31 AM Jym: California has a 1% lumber tax too
11:32 AM roycroft: sales tax is even more regressive than income tax
11:32 AM roycroft: my imac has been rebooting for the better part of an hour now
11:32 AM roycroft: i wonder if it will ever come back online
11:33 AM Bleepshop: roycroft: Yes, the local lifeforms seem to think that paying multiple taxes, multiple times for the same item is an intelligent course of action... :|
11:34 AM Bleepshop: No wonder NASA couldn't find any intelligent life on Earth... xD
11:40 AM JT-Shop: looks like the seller didn't make it to usps with my drive today
11:41 AM roycroft: or usps couldn't be bothered to deal with it
11:41 AM roycroft: their tracking system is becoming worse than the new ups one
11:47 AM Tom_L: JT-Shop, he can't be bothered with taking your money
11:49 AM JT-Shop: he done took my money
11:49 AM Tom_L: well there's definitely no rush then
11:50 AM JT-Shop: now to figure out how to jog before homing
11:50 AM Tom_L: set that constant to yes in each axis
11:50 AM Tom_L: or at least the one you want to jog in
11:51 AM JT-Shop: nothing in the axis section that I can see
11:51 AM Tom_L: HOME_IGNORE_LIMITS = YES
11:51 AM Tom_L: in joint now i guess
11:52 AM Tom_L: _should_ do it
11:52 AM JT-Shop: that's so you can home to a limit switch and all my joints have that set
11:52 AM Tom_L: hmm
11:52 AM Tom_L: mine jogs ok just about anytime
11:53 AM Tom_L: it will jog too far before i home it
11:53 AM djdelorie: random question: if you have separate inputs for the min/max limits, will linuxcnc let you move OFF a triggered limit?
11:53 AM JT-Shop: I think you need to see joint numbers not axis letters somehow
11:53 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/configs/NEW_MILL_SHOP_2.8.1/new_mill.ini
11:53 AM djdelorie: I know with combined limits, you have to override first
11:53 AM Tom_L: you can check for differences i suppose
11:53 AM JT-Shop: djdelorie, yes
11:53 AM * djdelorie is tempted to upgrade to that then
11:54 AM Tom_L: mine shares home/limit but home is offset from limit slightly
11:54 AM Tom_L: HOME_OFFSET = 0.050
11:54 AM JT-Shop: aye you have to move off the switch after homing or you get a limit error
11:54 AM djdelorie: I'm still using a parallel port so pins are limited, one input for min/home/max and sometimes the debounce doesn't work right and it just stops when homing
11:55 AM JT-Shop: hmm I need to install emc on this pc...
11:58 AM * Tom_L grabs a sammich
12:01 PM JT-Shop: https://github.com/LinuxCNC/linuxcnc/issues/182
12:02 PM Tom_L: huh
12:04 PM Tom_L: skunkworks, you around?
12:05 PM JT-Shop: NO_FORCE_HOMING = 1
12:06 PM Tom_L: in [TRAJ] yes
12:06 PM JT-Shop: nope
12:06 PM JT-Shop: still can't jog
12:06 PM Tom_L: probably that issue you just posted
12:07 PM Tom_L: i haven't experienced it
12:08 PM Tom_L: SW must really like me. they've emailed me daily for the past month or so
12:09 PM JT-Shop: it's something to do with QtPyVCP because in Axis you can jog before homing
12:09 PM Tom_L: now there's a possibility
12:09 PM Tom_L: i'd forgotten you were using your custom front end
12:11 PM Tom_L: well you just need it for testing the servo right?
12:12 PM JT-Shop: no I want to make a part by hand
12:12 PM Tom_L: oohhh
12:13 PM Tom_L: quick fix would be to use axis for it
12:13 PM Tom_L: then figure out what's wrong after the fire is out
12:16 PM JT-Shop: for today I just comment all home velocity and offset
12:17 PM JT-Shop: might be interesting to cut that slot with no lock on x
12:20 PM Tom_L: we need to see your final design :)
12:23 PM andypugh: JT-Shop: Keyboard jog? Jogwheel jog?
12:34 PM JT-Shop: mpg jog
12:34 PM JT-Shop: hmm didn't try keyboard cause it's around back
12:42 PM JT-Shop: hmm it's not going to work the way I thought... when I move the X by hand I get joint 0 following error
12:43 PM JT-Shop: I guess it's time to take the belt off of X
01:23 PM JT-Shop: https://gnipsel.com/images/machine-shop/wire-stripper/stripper-proto-01.jpg
01:35 PM norias: hello
01:37 PM JT-Shop: andypugh, I can move Z with my keyboard but it's not a standard keyboard so the arrow keys are weird
01:50 PM JT-Shop: drive got picked up by usps today so it might start it's way to me tomorrow
01:51 PM Tom_L: https://www.devever.net/~hl/freenode_suicide
01:51 PM Tom_L: fwiw
01:52 PM Tom_L: i'm going to cease logging freenode channels i believe
01:53 PM JT-Shop: https://gnipsel.com/images/machine-shop/wire-stripper/stripper-proto-02.jpg
01:53 PM Tom_L: seems like it might do the trick
01:54 PM JT-Shop: worked pretty good for a test
01:54 PM Tom_L: too bad you don't need the wire
01:54 PM JT-Shop: stripped 5 lbs. of hard to strip wire in a few minutes
01:55 PM JT-Shop: yeah it was some real nice wire
01:57 PM cloudevil: yay
01:57 PM JT-Shop: freenode linuxcnc still has 33 people logged in
01:57 PM Tom_L: little activity though
