I finished all of the mechanics on a diy corexy-frame co2 laser running mk4duo on ramps 1.4 and i’m now setting up the laser tube connecting ramps to the laser powersupply with ttl and pwm connections
When I press the laser test button in laserweb the two stepper motors make a loud cracking/knocking noise. they could be going a multible micro steps back and fourth or something.
Anything know what that is about? The same sound come when i testrun cutting curves i think
