I have a Sovol SV04 that I've replaced the motherboard with a BTT Octopus Pro. I've configured extruder 0 and extruder 1 to have minimum and maximum values where they can't collide.
When I test one nozzle at a time, it works without any problems with homing and printing. But when I have a file that should use both E0 and E1, it right after that the X gantry has leveled, E0 quickly makes a move to the right and hits E1, even though it exceeds its maximum allowed value. This of course, causes it to lose steps. What could be causing E0 to make such a strange movement?
I don't have anything in the start file that should do this, and it doesn't happen after the X gantry has been leveled in a print with only E0 or E1, just when both should be used!

Any info or suggestion is highly appreciated!
Regards
Johan
