what does this give you:
$ python3 --version

I wonder if using Deb 13 is the problem.  Deb 12 doesn't like my nic's or wi-fi hardware.

Assuming it's a python issue, any suggestions on what to do about it?

Like this one I built for a couple of plasma tables.

In these photos the motor is mocked up directly on the pinion, but we wound up using a 10:1 reducer between the motor and pinion.

Belt was T5, pinion was 15T (bought T5 15T bar stock).  Mr. Everman pointed out on CNCZone years ago that only T-series belt teeth/valleys are symmetrical - HTD and GT2/GT3 have non-meshing teeth.
 

I don't have any offsets set.

According to this the 'imp' module has been removed with python 3.12:
stackoverflow.com/questions/77274572/mul...-no-module-named-imp

But according to this Debian 13 is on python 3.11.2:
www.debian.org/releases/trixie/release-notes/whats-new.en.html

might want to check what python version you are running.

The Bell-Everman drive is a nice system, but you need to put any reduction upstream/ahead of the pinion.  As Tommy pointed out the 72T idlers won't reduce anything.

A low-backlash, helical gear reducer between the motor and the pinion is the way to go.

And if you've got the space for some extra carriage length, the 'Loop-track' system brom B-E is really nice.

this is why i got the 3d printer to test stuff and not spend much money on idea's i probably have OCD i have to see stuff with my own eyes before i give up on anything i share the good bad and the ugly regardless of outcome

I'm really sorry for my earlier knee-jerk post.  The newer versions of the Fanuc spindle motor are PMs, so it's possible that yours is also a PM.

yes, but if you are looking get access remotely you may have slow UI.
systemctl disable lightdm that work in my case works perfectly.

you can install linuxcnc 2.9.3 and you may need to activate some option to make the /dev/sdev0.0 to get active also may have slow graphic interface if you are using virtual remote as I do. but that is something easy to fix.
I'm talking about 7c80 board, if you are looking to use a different board you may need different settings.

I have the same problem here with the WH04B-6. Cant see the device on any ports. I checked my bios and the legacy usb is already enabled. i enabled some other usb stuff with no results. Any luck fixing this?

Yes that's the cable thanks. I will report once I get it all connected.

Try a slower acceleration

Adam, Still running fine however I really only use it a few times a year. I can't believe its been 8 years. I don't really have any suggestions. Did you get yours converted over?
