Printer prints 3x the speed it should

I have a Mendel Max and a Lulzbot Taz 3. Gcode that runs just fine on the Taz 3 will run about 3x the speed on the A0-100. We've tried marlin and repetier firmware as well as the original firmware that came with the printer, all to no avail.

We've had the problem since we fried the arduino and RAMPS v1.4 board.

I've checked the jumpers for micro stepping and they appear to be correct.

Any ideas?

Have you tried calibrating your steps per mm? If it's still 3x the speed after calibration (I'm guessing this is an estimate) then it's likely micro-stepping is to blame.

Yeah, that's what I suspected. I'll re-calibrate and report back. It's got to be something with the firmware or the RAMPS board.
