It's almost a year and a half later. Has anyone updated the probe-screen-ng to Python3 and LinuxCNC 2.9._ ?

It mentions a filename vartokins.py, I don't have that here so I don't know what that is.

There are probably several things. But let's start with the line
"loadusr -W ./lcec_conf ethercat-conf.xml'"
Remove the ./ and it will find the lcec_conf module at /usr/lib/linuxcnc/modules/lcec_conf.so
The filename ethercat-conf.xml on that line must match the file name where you have the config. You attach ethercat-conf_2025-02-26.xml.  If that's the one you use use the line "loadusr -W lcec_conf ethercat-conf_2025_02_26.xml".
You will get error because slave 0 and 2 do not have hal pins with the mentioned names. You had them as basic cia402 in the earlier xml file. Either go back to that or change the pin name in ethercat-conf.xml the "halPin" value there.
There is no slave 3 in ethercat-conf.xml so you will get errors when trying to use lcec.0.3.out-03 in the hal file.
 

Chris,

With ChatGPT's help I think I have found enough examples to have a go at this. I'll report back with how it goes. Thanks for your guidance.

Hello, 
i have a delta VFD-H, i have checked the manual there is no mention of modbus, only Serial Communications rs485 is mentioned, can i still use it with linuxcnc over rs485 ?
 

Thanks for that. I had a little formatting issue with my post that I corrected.

However, since I don't have enough inputs with the parallel port type setup to put the fault line from each driver to its own input, all three will be going to a single input. This will be corrected once I get a Mesa 7C81 if they ever go back into stock.

So, for my current setup I could do this:

net driver-fault <= hal_gpio.GPIO25-in
net driver-fault =>joint.0.amp-fault-in

Which would trigger a x-axis driver fault no matter which driver actually had a fault and stop all motion. Is this correct?

Incidentally, for my own education is this line the same as the above two lines except just on a single line?

net driver-fault => joint.0.amp-fault-in <= hal_gpio.GPIO25-in

Thanks.
