Tested the macros.cfg change on a Centauri Carbon with CANVAS, COSMOS 26.08.0. This is the same failure #315 was for: a cancelled print leaves relative mode on, and the next T0 died in homing_override with Move out of range: 364 156 170.5. With this change, G91 then G28 from a cold restart homes cleanly and ends in absolute mode, and the exact post-cancel case, XY homed, Z unhomed, relative mode, G28 Z, does too. Ran each twice, no errors. Thanks for picking it up.
