As i understand it, it is a RPI manufacturer issue, most probably hardware side of things, as i doubt if software issue it would have been solved by now.
As far as i recall, there are several versions of RPI5 and back then any new version would be crippled by issues for a long time, plenty of videos on youtube about that.
Chip shortage caused a lot of headaches for all manufacturers, but the way RPI owners handled it, is by far the worst way, ignoring issues and waiting for others to fix the issues while they were busy getting rich from the 180$ price tag.
Same ... well much worse, with Intel, blaming everything and everyone while knowingly selling 400-1100$ processors. Millions of it.
Personally, i blame humans for standing that kind of s#it. I do not, vigorously!

In regards to "The 7c81 product page at Mesa states that the 7c81 will not work with the RPi5". I was wondering if the Mesa company writes the driver normally or if the missing support for the RPi5 is something that is part of the LinuxCNC 2.9.3 image?

i dont think anythign you change in qtvcp will change axis.

which one are you trying to set? the one in the manual tab or the one beside the sider?

"are there good docs?"
only what Phil has made for the axis docs, otherwise it gets rather confusing because we are passing tcl/tk as strings through python, so its not tkinter, and its not just tcltk

this is the best site, as well as using plasmac2 config as an example

www.tcl.tk/man/tcl8.6/TkCmd/label.htm
github.com/LinuxCNC/linuxcnc/blob/master...plasmac2/plasmac2.py

here is my shitty one, but its got good references
github.com/cakeslob/regularmac_800

This should be an easy thing, but my facility with tk is not great.  I want to change the text of the spindle override widget without editing the /usr/lib/python3/dist-packages/qtvcp/plugins/status_label_plugin.py file where it is set up in the first place.  I have successfully changed text of the .pane.top.tabs.fmanual.spindlel label widget using the tk call shown in the Axis documentation:

root_window.tk.call('setup_widget_accel', '.pane.top.tabs.fmanual.spindlel','Wire Voltage')

This does not work for the tkinter.Scale widget spinoverride or spinoverridef.  I'm sure I'm missing some simple step.  Is there a good set of documentation for the tcl/tk code interface for working with widgets?

Thanks again,

I managed to install Linuxcnc on an old pc.

It seems for what I want or need.
a 7I95T + THCAD2 would be the way to go.

The thing is my machine is Router/plasma combo with rotary and laser and on top of that a probe will need to be installed.
In the future I will separate the tables.

Thanks to all!

 

Thank you!
some great info.

Its a three phase transformer its for the versions that run on 380/400v since the spindle drive use 220 three phase power i think. And three phase doesnt need neutral to work its the phases that have 380V between them

Try a Meanwelll MDR-10-5 (2 amp)

My guess is gpio16 does not exist. remove it

Would you be able to suggest a power supply to me? Thanks

No. even a USB plugpack isn't reliable

Hi inspirr

Unfortunately not. I think the default encoder setting of the ECT86 should be alright for most steppers though. I tinkered arround with lots of other settings as well. But had to give up on it for now.

Am I able to power the card from a usb cable from a computer?

Hi there, nice work the s curves look nice on the videos on youtube. I would like to work on this too. What is the state of the merge with the main branch? i see the last commit was 4 months ago on the branch of Grotius, how are things going? what can i do to help?

Thanks Peter. I have updated this document which explains how to get the most out of your PC hardware when using Bookworm or Trixie.
