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...

Ah... Jumpers? I didn't configure any jumpers under the drivers, but now I think of it there are pins on the RAMPS under the drivers which I meant to look up. Do you have any idea how they are...

Based on rated values, you may be good. Now if anything is out of spec from what they are suppose to be, then you may be under powered. It's not uncommon for a power supply to be overrated, and if...
