I have a Sherline CNC Lathe with the computer system from Sherline. The
disk drive failed. I replaced the disk and installed LinuxCNC 2.7.14.
The install completed without error - great job.
I have a problem with backlash and overshoot.
The config file has a strange entry:
AXES = 3
I measured several rotations of the Z-axis lead screw on my Sherline
4400 CNC lathe.
The BACKLASH setting is 0.0035
I started with a move in the + direction that was at least 2x the
backlash clearing I saw earlier.

1. Fetch the RTAI deb's into ~/RTAI:

wget
Upgrading to buster was successful.
I got the RTAI kernel installed.
linuxcnc has dependency problems. It wants python-vte, which wants

If I install libvte-common=1:0.28.2-5, it breaks other things...
