Hi, i can share my code but it’s a very old version.
Can you decribe your problem more specifically?
@Luca_Baruzzo now x2 carrage can homing to + direction, but can’t print when tool change to T1 , it just go to center of bed and move back to xmax-pos , then back to center again and then x carrage come to hit x2
x2 hotend and fan didn’t work when printing , but I can control it by manually.
I use rumba board with Marlin bug fix 1.1.x
Older version maybe without some function but still good, because newer version has some bugs I think.
