Hello!

Since I posted lots of questions on this list about the plasma table I
was building, I thought that I should share something:

I took that video with my phone.
I was not able to get the servos work correctly, so I ended up with
stepper motors, which included also new gearboxes with smaller
reduction ratio.

I wrote a custom kinematics module for that machine for better THC
process - thc offset is added there so that LinuxCNC and user always
know the actual joint position. That means that machine soft limits
are never exceeded.

The thing yet to be solved is the fact that calling MDI commands with
gladevcp buttons switch LinuxCNC to joint mode. There are simply
gladevcp buttons, linked to halui.mdi-command-nn pins and in INI file
I have defined some actions, like G53 G00 X5 Y5 Z100 or G0 X0 Y0. If I
use any of these buttons, LinuxCNC will switch to joint mode, once
that is completed.

Can anyone explain, why is it so and what can I do about it?
