hey there!

After running gridprobe.ngc, the values are written in a .txt file.
is it possible to transfer them directly into my program so that the z-values will be corrected automatically?

Are you trying to correct for a non-flat workpiece?

If you google for "probekins" you might find some interesting pointers. This is a "partially solved" problem.

It might be possible but that depends on the function of the spinbox... so far not enough information has been revealed to answer your question.

Probably. Typically you would connect the spinbox output to the analogue-input pins (motion,analog-in-00 etc) which are then readable from G-code with an M66 command.
(There are rather more layers than you might expect)
