Yesss! Got lathemacros working (unmodified).
I got hold of an older version of rsvg (for Pi 3 or older, I suppose) from here
packages.debian.org/stretch/armhf/python-rsvg/download
dpkg --install <package>
then got an error on "Xlib" not found.
apt install python-xlib
and it is all working! Yess, that was the final piece that was missing.
I did some manual turning yesterday. It all works fine. My normal setup is
a quick Intel Core i3 6100 on this machine. RPi4 doesn't *feel* quite as responsive, but
it is just the occasional microdelay. I press a key on the gamepad and it takes
just a tiny different amount of time. The screen response 1920x1080 with
touchscreen is absolutely acceptable. Not as quick as the Intel though,
but workable no problems.
Now when LatheMacros works I will have the RPi4 on the lathe and see how it goes in
long term.
I looked at the output from linuxcnc.
There are some ten of those
Code:
task: main loop took 0.024097 seconds
during GUI buildup. When gmoccapy is up and running
and the machine is ready so to say there are no more such messages.
If I let it sit idle, there is some screensaver that shuts everything down,
including networking so that need to be fixed. Probably easy, I will not
dig into that direction.
