Re: Motors do little steps, not big ones.

Thanks again, that seems to have solved the first problem. I changed the X/Y to 300 which works a treat. Z I had to change down to 10. Any high and it won't work. I assume this is because one revolution of the motor spindles in Z represents less distance than one turn of the X and Y motor spindles.

Interestingly, the home buttons (sort of) work. X and Y do a high pitched whine, then suddenly whap the bed back to its homed position against the stop. Z just whines and does nothing. I'm guessing the home buttons home at a preset speed, I did turn on debug codes, but wasn't paying enough attention. I'm assuming they send a code for "Move towards minimum until endstop is triggered" with a speed that's too fast.

Question: I want to check the stepper drivers are configured with the correct output voltage. Any idea which pins I measure across? These are the drivers I have. From the picture it should be easy to probe the terminals at the pot, but in reality I can't hit those points.

The end stops and motors were all wired up backwards, I now have minimum Y as the bed as far from me as possible which seems counterintuitive to me. I should probably check that too.
