P4 was not found on amazon.de so S3 it was.
Had a play with this earlier today, Wez's version fails to set networking for some reason on ESP32wroom module, the other version someone linked here does work but suffers from random reboot loops, a lot.
I am after something else here, use an ESP32 as it has 12 bit ADC to measure the arc voltage and turn the torch on, mounted on the plasma source, and another module connected to PC to translate those voltage values to pulses with variable frequency.
Should be doable and have good enough latency for about 50-150 updates per second. It they survive the EMI

Hello CNC'ersGreat forum all, many many questions already answered !Many thanks..however....Am trying to configure Linxcnc using Touchy UI.I keep hitting the same error, see attached report.If I switch the UI to Axis in the ini file, it starts no problem.I've searched on the forum but there is surprisingly little on Touchy and seemingly nothing for the warning the report gives.I'm using a stock OS Linuxcnc image for the RPI 4B with a Mesa7i96s, nothing convoluted. Debian 12/Linuxcnc2.9.1All advice welcome !!

hi,

if you are building ethercat-master from source... there is possibility to disable eoe on master during ./configure script for example
but I am fighting with them right now to install non generic driver because in responsitories is only generic possible ..

Unfortunately that did not work either.

I tried pulling apart the X and Y movement.
It stops at the X movement.
If I put Y first it completes that command but than stops at X.

i'm not sure how fancy this is going to get i am looking at cheap steppers and drives to do this cheap THC might be basic too i have to look into that part more while i am collecting parts. the whole THC is new to me so i have some learning to do for sure on that part. i made a breakaway torch holder a while back and it fits this torch so that's about as far as i am right now.

Tommy. You honestly need to lookup RMT based controls if that 32bits is your hardware (suggest the P4 if they are available to you). If you're after half-decent motion control performance and reliability, that's the only way to do it really (imho). Yeah man, from scratch!!

That, and grab a good doze of knowledge of mutual exclusion runtime(mutex, semaphores, give, take, locks, ect), and the end result should match up to as close as it gets to a parallel compute (aka fpga).

to save 30 seconds out of your life try

sudo shutdown now

You might need to give permissions to skip the sudo password

I wonder if Wez is OK...

Totally cool project yeah, I remember looking into it during its infancy but wasn't geared up to import and compile any of it I think Wez attempted a proof of concept here, which he materialized already, however I sense he lacked the courage or perhaps the time to complete it. I looked at it again a few hours ago and it seems to be only missing the timing critical & comm integrity on the blocking/non-blocking/locking threads and other runtimes. Haha maybe you can finish it up (hardest part though, need a sharp oscope and a vivid logic analyser, beware!!).

I'm sure he's fine. Obviously busy with worlds' more important stuff, we all are!

 

if you look carefully at the pics on page 3 you should be able to figure out the wiring.
One pic shows the ribbon with two groups of wires.
one starts with a black wire and ends with a gray wire.
one starts with a brown wire and ends with a brown wire.

black to gray is for megas's pins 23 to 47
brown to brown is for pins 2-12

The IPTM-60 is non-HF which implies blowback type.
The naked tip does not lend itself to ohmic sensing because the tip is shorted to the work lead clamp until it blows back, You can test this with a multimeter on tip to ground clamp. The solution is to use an external probe probably lowered with an air ram. QT plasmac supports offset probing for  this but more inventive folks lower a circular probe that encircles the probe tip.

Only other thing I can think of is to add 'G0' to those 'G53' lines.

Hey PCW,

I can give it a shot at least. Since it'll show up as a 5i25 after flashing I think it should work with the correct bit file.

Thank you!

Looks like your config is looking for a directory that is no longer there:

 
[edit]

I'm not aware of a file 'null.ngc' in a regular installation so maybe that is something you have customized in the previous version.

edit: problem solved
outpins works like a switch, but had my probe connected with the wrong polarity ..

It is T bot. But kinematic is same for all of them afaik. Driving in same direction - moving along motor axis, driving motor opposite - perpendicular axis is beeing moved.
