Hi!
I just finished my MendelMax 1.5 build. I uploaded the Marlin firmware, and the X-axis seems to work ok, but Y-axis is very jerky. It'll move a few inches, then the motor will sound like it's grinding but it's actually not moving. It kind of moves but very choppy. The Z axis does nothing but hums when I try to move it using Repetier-Host but doesn't even budge. I tried turning the potentiometer all the way up (clockwise) on my power supply. I'm using everything that came with the kit. I can't think of what else to try. I've never gotten it working past this point before. I tried other firmwares including Sprinter, but after uploading it, I can connect to it using Repetier-Host but absolutely nothing responds. Can't move the motors nor heat up anything. I've tried the test code, and my X, Y and E motors all seem to move back and forth (E seems to be choppy and jitter as it spins. But Z doesn't do anything. I'm not sure if it's supposed to move using the test code or not.
My PSU is 12V / 29A. I'm using RAMPS 1.4 with Arduino Mega 2560. It almost seems like the motors aren't receiving enough juice.
Please help!
