Hello!
I need to build a machine for rotary milling of wood parts. The thing
is that customer wants the parts in the rotary head to be swapped
automatically, so some kind of cnc-operated chuck is needed.

Hello!
There is a plasma machine I built and I used THCAD-10 card for thc
purposes, because the plasma source had such an output signal.
Long story short - the machine has new owner and they want to use
JasicCUT plasma source, which AFAIK does not have 0-10V signal output
for thc, so I will have t

Hello!
I was playing with the config on my router, when suddenly I started to
receive this error message.
I was configuring rotary axis, got it turning, so I changed stepgen
scale in INI file, restarted LinuxCNC and got this error.
I tried reverting whatever changes made also prior scale change, d

Thank you very much for the tip, I already had spent considerable

Just jog up to corner and run the file? How do you apply the G92
offsets then? Are there some commands in beginning of g-code file? If
yes, then

So far I always taught my customers to use G54, I actually never
thought about using G92 for setting origin of part coordinates.

Hello!
I was asked about the machine, that basically does this:

The problem is that they cost around 10K $, which seems way too much.
I tried some researching on topic and found out that manufacturers of
these machines do not reinvent the wheel and use

Yes, "drift" can be in any direction, but the change of direction
happens only on system restart.

Hello!
I have a strange situation:
Stepper motor of Z axis on a cnc router is losing it's position -
doing a series of numerous holes in material will end up with various
depths of holes.
The strange part is:
1) for each time, when machine is running, it will lose position only
in one direction;
