Linuxcnc ignore stored position for specifix axis was created by pingtomi
Hello,
I use POSITION_FILE statement in [TRAJ] to not loose positions upon exit. For A axis I installed absolute encoder to find easily always zero position (when tilt table is parallel with Y axis).
I use HOME_ABSOLUTE_ENCODER = 1 in [JOINT_3] section.
However I noticed stored position information is taken into account by Linuxcnc upon start instead of the position of the abs encoder, this is what I'd like to change.
Is there a way somehow to not save A axis's position or ignore it and use encoder's value?
Thank you
Tamas

There might be a way to do what you want, but I am not sure how.
What happens if you remove the reference to A from the position.txt file before you restart LinuxCNC?
You can almost certainly do his by creating a custom homing routine, but I would hope that there is a simpler way than that,
