[11:34:45] <Joe_Hildreth> At the risk of sounding dumb, if Wheezy is at EOL with no security updates, will the install media be changed to something else?
[11:35:24] <Joe_Hildreth> I thought I remember seeing a link to a Jessie or newer iso for LCNC. An I imagining that?
[11:36:00] <x2s> well, there is a branch for Debian Buster and I've got it running with Buster and a rt-kernel
[11:36:33] <x2s> but Debian removed some packages necessary to build and run linuxcnc and I had to create them myself
[11:37:02] <Joe_Hildreth> That may be beyond my skill set. :-)
[11:37:38] <x2s> Sadly rtai doesn't seem to get updates anymore (or at least I haven't seen them). I guess rtai would be better than the rt-stuff in the mainline kernel.
[11:38:35] <Joe_Hildreth> Where does uspace fit in the puzzle?
[11:40:10] <jthornton> Joe_Hildreth: there is a stretch livecd
[11:40:49] <Joe_Hildreth> John, Awesome, do you have a link? Or can a link to it be provided in the downloads docs?
[11:41:04] <jthornton> http://www.linuxcnc.org
[11:41:11] <jthornton> that's for 2.7 only
[11:42:00] <jthornton> my instructions to build debian 9 or linux mint 19 http://gnipsel.com
[11:42:43] <Joe_Hildreth> When you say for 2.7 only, does that mean 2.7 and newer or only 2.7.x release of LCNC? Sorry if I sound ignorant. :-)
[11:42:51] <jthornton> no one is currently working on a new livecd that I know of
[11:43:43] <jthornton> the stretch iso is 2.7, you can change it to master but it might be easier to just follow my instrucions for the os and verions you want
[11:45:37] -!- gloops has joined #linuxcnc
[11:45:37] <Joe_Hildreth> Looking at your page, I see Deb 7, 9 and mint. Does this work for any deb based OS like *buntu?
[11:46:18] <jthornton> I've only built the ones listed, the others you would have to try yourself
[11:46:39] * jthornton heads back out to the shop
[11:46:58] <Joe_Hildreth> ok. Thank you for the links sir.

[12:12:41] <xunil> hi folks, anyone using a torch height control system on a plasma machine with linuxcnc?
[12:18:23] <Tom_L> i'm sure someone is
[12:19:20] <xunil> lots of folks on the forums are, was just hoping for a more real-time conversation about it :)
[12:19:58] <Tom_L> i'd ask what you want and wait for an answer. someone will show up sooner or later
[12:20:18] <xunil> my friend built a table and i've just gotten the axes moving with a Mesa 7i92... have a Mesa THC card hooked up, and i had started with the external offsets branch, but it sounds like the 'hpid' solution is deprecated and there's a newer component
[12:20:38] <xunil> just wondering what others are using for tying the THC feedback to the Z axis, and how it's working for them
[12:20:44] <xunil> and the procedure they use for tuning it
[12:21:35] <Tom_L> skunkworks has a video of it somewhere
[12:21:49] <Tom_L> following a corrugated sheet of metal
[12:22:02] <xunil> sweet :)
[12:22:09] <Tom_L> that it is
[12:22:19] <xunil> i'd be happy with the torch just not plunging into the sheet i'm trying to cut
[12:22:32] <xunil> (poorly tuned PID on the hpid config i'm using right now)

[12:31:29] <Tom_L> don't think this was his but it's quite similar: https://www.youtube.com
[12:33:04] <xunil> that's really impressive!
[12:33:28] <xunil> i'm curious about the cylinder pointing out to the right on that bracket, too, i wonder if it's a proximity switch for height sensing
[12:33:38] <xunil> i still need to figure something out for that for my friend's machine.
[12:33:48] -!- CaptHindsight has joined #linuxcnc
[12:35:03] <Tom_L> CaptHindsight do you do plasma?
[12:35:22] <Tom_L> xunil is wondering about THC
[12:37:42] <xunil> i have to step away for a little bit but i'll check back later.
[12:38:50] <Tom_L> there are logs if you miss it
[12:52:37] <roycroft> i finished making the power unit for my belt grinder last night
[12:52:56] <roycroft> i have some fasteners arriving today, then i'll be able to mount the motor and idler wheel
[12:53:04] <roycroft> and i'll make the platen this weekend
[12:53:15] <roycroft> my welds are wicked strong, but pretty ugly
[12:53:29] <roycroft> tig welding is fun, but requires some finesse that i have not yet attained
[12:54:04] <roycroft> i'm not sticking the electrode every 2.74 seconds any more, though
[12:54:16] <roycroft> that's progress?
[12:56:44] <roycroft> i'm also spending less time grinding welds than welding, so also progress? :)
[13:07:14] <CaptHindsight> somewhere there's a component for real time Z (or other axis) offsets for THC and other applications
[13:07:18] <CaptHindsight> have to look for it
[13:07:38] <CaptHindsight> real time or real time-ish

[16:20:34] <Connor> pcw_home: Got someone working with a 6i25. Converting the machine from Mach3 to LinuxCNC. 2000DSLS from Micro Proto Systems. Was using a UC100 (USB Parallel port emulator thing, but the 2000DSLS can use standard ParPort. She says it's not seeing the card.
[16:20:42] <Connor> Need to get the 6i25 setup to work as a generic ParPort I guess??
[16:20:56] <Connor> I've always used it with a 7i76.. so, I'm not sure.
[16:32:33] <JT-Shop> flash it with the g540 firmware
[16:35:28] <CaptHindsight> issues # 1: USB --> LPT emulation won't work in real time
[16:35:38] <CaptHindsight> check the pinouts
[16:37:04] <Connor> That was Mach3 and the UC100 had specific drivers to make it work.
[16:38:02] <CaptHindsight> i have a few more questions so that I comprehend what it is you are trying to do
[16:38:55] <CaptHindsight> the 6i25 is a PCIe FPGA card attached to the PC, what is attached to the I/O of the 6i25?
[16:38:59] <Connor> Converting a Mach3 lathe to LinuxCNC. Ditching the UC100 USB--to-ParaPort for a 6i25
[16:39:15] <CaptHindsight> http://store.mesanet.com
[16:40:04] <Connor> It's plugging into the proprietary controller unit which can use a parallel port.
[16:40:41] <CaptHindsight> ah, it expects to see LPT connections and signals
[16:40:41] -!- justanotheruser has quit [Ping timeout: 246 seconds]
[16:41:15] <Connor> Yup. So. Out with the UC100, in with a 6i25
[16:42:16] <CaptHindsight> what signals does the proprietary controller expect to see on the LPT connector?

[16:43:25] -!- andypugh has quit [Client Quit]
[16:45:09] <Connor> I'm not sure. I don't have the 2000DSLS manual in front of me.
[16:45:51] -!- togo has quit [Quit: Leaving]
[16:46:15] <CaptHindsight> the 6i25 has a physical connector just like an LPT port but how is LCNC going to send control signals and what control signals to your proprietary controller?
[16:46:37] <CaptHindsight> anyway bbl
[16:46:47] <Connor> It's expecting a parallel port.
[16:46:54] <Connor> I dont know the mappings right off the top of my head.

[22:19:02] <elmo40> Tom_L, is that helical cutting for threading or basically anything?
[22:19:39] <elmo40> helical milling is very efficient. no stepping lines.
[22:20:07] <Tom_L> i wrote it for thread milling, i suppose you could adapt it for anything
[22:23:42] <elmo40> will it only do circles?
[22:25:27] <Tom_L> yes
[22:25:42] <Tom_L> it's a macro for my cad cam. i doubt anyone else could use it
[22:25:57] <Tom_L> JT-Shop is working on a more open solution though
[22:26:56] <Tom_L> using QtPyVCP
[22:37:19] <Lcvette> what do you use to make a linuxcnc install thmbdrive from a windows machine?
[22:37:35] <Lcvette> Tom_L: ?
[22:45:54] <Tom_L> i've only done it once or twice
[22:46:02] <Tom_L> just a sec
[22:46:22] <Tom_L> from an iso?
[22:46:38] <Lcvette> https://www.balena.io
[22:46:46] <Lcvette> think this is what i used the last time
[22:47:05] <Tom_L> i want to say rufus or something like that
[22:47:21] <Tom_L> yeah
[22:48:05] <Tom_L> https://rufus.ie
[22:49:00] <Tom_L> what are you burning to it?
[22:49:51] <Lcvette> 4gb thumb
[22:50:07] <Tom_L> what target iso?
[22:50:18] <Lcvette> the uspace stretch test
[22:50:43] <Tom_L> i'm pretty sure i used rufus for one i did once
[22:50:51] <Tom_L> i've used it more but not for lcnc
[22:52:23] <Lcvette> i used rufus in the past but i had problems with the stretch iso using it
[22:52:30] <Tom_L> ok
[23:11:20] <Rab> I just use dd, what am I missing??
[23:13:26] -!- justanotheruser has joined #linuxcnc
[23:15:08] <Lcvette> yeah but that renders it useless for anything else
[23:15:48] <Rab> Oops, sorry "from a windows machine"
[23:17:00] <Kevin`> there's plenty of installers that aren't compatible with random files existing on a drive. you'll have an easier time if you resign yourself to reformatting the drive afterwords to put random files files on it
[23:17:35] <Lcvette> https://www.balena.io
[23:17:41] <Lcvette> bar none the best one ive ever used
[23:17:52] <Lcvette> simple easy and works
[23:18:49] <Lcvette> i have seevral laying around myself but trying to help windows buddy's load linuxcnc for the first time is challenging when they don't know much of what they are doing
[23:19:26] <Lcvette> that link simplifies things, kinda idiot proofs it
[23:19:28] <Lcvette> lol
[23:25:04] <Tom_L> i marked it for future reference
[23:28:13] <elmo40> can't unebootin?
[23:29:21] <pcw_home> Lcvette: That looks about the same as mine, for Ethernet you do need to disable AMT in the BIOS and do the IRQ coalescing trick shown in the hm2_eth manual page
[23:33:28] * Lcvette sent a long message: < https://matrix.org >
[23:33:30] <Lcvette> this?
[23:34:03] <Lcvette> oh
[23:34:26] <Lcvette> whats AMT?
[23:34:50] <Lcvette> i disabled power savign stuff that i saw
[23:36:08] <Lcvette> pcw_home:
[23:36:16] * Lcvette sent a long message: < https://matrix.org >
[23:36:22] <Lcvette> this trick?
[23:36:55] <pcw_home> yes, that's needed for Intel MACs
[23:37:41] <Lcvette> so just add it under the other network thing?
[23:37:50] <Lcvette> or replace part of it?
[23:38:16] <pcw_home> AMT is something that needs to be disabled in the BIOS
[23:38:21] * Lcvette sent a long message: < https://matrix.org >
[23:39:38] <Lcvette> so make it like this?
[23:39:43] * Lcvette sent a long message: < https://matrix.org >
[23:40:15] <pcw_home> yes the last one (plus disable AMT in the BIOS)
[23:40:53] <Lcvette> will that mess up the wifi?
[23:41:26] <pcw_home> no, its unrelated
[23:41:37] <Lcvette> so i can add it to the bottom
[23:41:49] <Lcvette> or replace the top section
[23:41:56] <pcw_home> you cannot access it anyway except the BIOS
[23:42:11] <Lcvette> not the AMT
[23:42:22] <Lcvette> the network stuff
[23:42:24] <Lcvette> lol
[23:42:48] <pcw_home> the IRQ stuff is interface specific
[23:42:50] <Lcvette> i had to do the fix already to fix the hang on boot
[23:43:11] <Lcvette> which is the top 4 lines
[23:43:15] * Lcvette sent a long message: < https://matrix.org >
[23:45:09] <pcw_home> sure your internet interface will normally use DHCP (or IPV6) but the Mesa card interface must be static IPV4
[23:46:38] <Lcvette> wait is this the thing that i had to do on the other machine and make it 10.10.10.1 or wsomething?
[23:46:51] <pcw_home> yes
[23:47:00] <Lcvette> ah.. coming back to me
[23:47:12] <pcw_home> 10.10.10.x is preferable to 192.168.1.x
[23:47:22] <Lcvette> so i can change that 192.168.1.1 to
[23:47:22] <Lcvette> ok
[23:47:23] <Lcvette> lol
[23:47:30] <pcw_home> less likely to overlap DHCP ranges
