Hi,
I would like to know if it is possible to read and write ie. variable number 4999 from .var file with Python? Is there an example?

Hi,
This was considered as one option for saving tool on spindle number to variable number 4999. GladeVCP panel for ATC alredy had some Python script for showig ATC states. But we solved saving tool number with Remapping M6 with file containing:
M6
#4999 = #5400
M2
This seems to work ok.

Hi all, I am new with LinuxCNC.
I have made macro to automatic tool measure. Now I think about saving parameters of starting milling (position, XY in respect to machine cordinates, Z to tool sensor etc).
What is the simplest way to save those parameters in occurrence to crash / tool broke. I now that it will not be ideal.
I thought about any system parameters. Is it good way?

You might look at the (abort, xxxxx) "magic comment" if using a G-code routine.
linuxcnc.org/docs/2.7/html/remap/remap.h...g_dealing_with_abort
It is possible to set and read G-code parameters in Python, this code here does it:
github.com/LinuxCNC/linuxcnc/blob/master...athe-fanucy/remap.py
It sets the #<tool> parameter. But I am not 100% sure what the requirements are for that to work if you are not using remap.
