Thanks, you put my mind at ease. I ordered a refurbished ThinkCentre M710q last night and got the MESA card ordered. Now I have a table to build while I wait for the hardware.

I use M codes for this kind of stuff also. For example M130.

Use with:
M130 P255

I am not sure right know, but I had something in mind while writing  "&".
Also some sleeps are always a good idea. Sometimes it gets lost otherwise.

Best regards

Did you finish the machine yet?

As Darth Vader once said: welcome to the dark side!

I know it's nothing to you experts, but for me it's a big step.

hi guys i managed to get the communication between Rp1 7i97t+7i744+7i84+7i73 working
Thank you for your help.

I would really like to, but I have to wait a little bit with the next invest in my hobby.

Thank you so much for your hints and ideas!
Yes the optidrive should stay in my setup - at least for the next months. The switch to ethercat, the new servos aso was hard enough to afford. As you mentioned before usb to rs485 is an option, I will go that way until I will be able to spend the next bucks for an ethercat VFD.

Gotch ya. How do I add the key? When I try to save it to trusted.gpg.d it says I do not have the proper permissions

I've passed this on.

We can't decide anything, but we have the amazing Pull Request tool.
Norbert or Hans merged all the important PRs I made. Or they directed me on how to edit these PRs to make them acceptable to them.

I'm writing this here because I think it's a shame that you'll do some work that ends up in the depths of the forum.

Atom is the cpu.

I've had good results with 3rd gen 4 core i5s, specifically Lenovo M73 tower, works well enough for software step generation.

Ex corporate PCs (x86/64 platforms)seem to be best bang for buck, RPi5 with a NVMe drive are quite quick, latency is usable, I've had one on the test bench communicating with a 7i92 for a few weeks with no issues. Spent a few weeks in January putting together the RPi Linuxcnc images that are for upload.
Odroid have a good range of compact x86/64 boards, I have an earlier model H3 plus that's been in for 4 or 5 years.

Asrok J series MB work well, either 4 or dual core.

Personally I would choose option 3.
I have suggested to make individual GUIs more self contained and modular. Would clearly make the code base bigger but it would be a lot easier to maintain things in the long run an also make it a lot easier to clean out the outdated and broken ones.
But neither Gmoccapy nor any of the other guis are my projects so it is not my decision to make.

Actually, it does run on 2.9.4 after installing 'python3-pyqt5.qtopengl' as suggested in the debug output but there are clearly other problems:
