what i found with my nylon sls shuttle is that it behaves the same when heat soaked, also becomes more loose. (same to your aluminum) my next try will be to print all the docking components in ASA GF, maybe that keeps stuff rigid ^^
Interesting update. But how do you probe z, if its not clicking back by itself? Is the movement while probing so little, that it moves back or am i missing something here? Greetings....
the clicking is it clicking into the rail, flexing a little if it was without magnets thered be 3mm or so linear movement without resistance, and then a small bump to overcome, and then the tool would drop out. the 3mm linear motion is whats used for tapping.
there are CANbus splitters to help you, but with CANbus, you can run them all into one port, it detects the different boards on the other end regardless
IS there a way to align all the nozzles? Could you show it? All heads are not the same so there will be X Y and Z offset for each toolheat, how do you aling them?
