In this version it don’t do a G28 X at the end. Will check out the new version from 20240508
My issue wasn’t a missing G28 X at the start but when the printer starts the print.
If the left extruder started to print the right extruder wasn’t parked. Now the left extruder couldn’t reach all the way to the right.
And glancing at your newest start code it don’t do a G28 X before start printing. But i will try it out this evening or tomorrow.
