At the begin of my session, X offset was 3.8mm and it works perfectly. X and Y offset was registered in the profil.
Suddenly between 2 works, I seen a glitch on the screen and the image translate laterally, and now to be align I’ve been obliged to set the X offset to 0.8mm !?
Something to add to my post.
I’ve some profiles for the same set-up (openbuilds acro-55).
My first concern was with the pen-config.
Later, I switched to use a laser. Some offsets X and Y (slightly different values) were also stored. Then I noticed that the same ~3mm X translation have occured.
