@cosmowave said in Controlling multiple machines at once:
Perhaps there are some tricks to do that?! I don't know.
I prefer to build machines with separate controller boards...
One could set steps/mm to "0" for a machine that should stop. (E.g. M92 U0 V0 W0 Enn.n:0:mm.m)
I agree about separate controllers, but just for fun...
