Prusa steppers work with ramps 1.4 test code, but not in pronterface

Hi. I was wondering if anyone could help me troubleshoot a problem that I am having in with getting my motors to move in pronterface. I am building a prusa and I am using a mac, and ramps 1.4 with marlin firmware. I tested the motors, hot end, and heated bed with the test code and everything seemed to work fine, but in pronterface my motors hum and if they do move they only move slightly. Any help would be greatly appreciated.

Did you ever solve this? I'm having a similar problem

test could doesn’t check endstops real code does

test codes has a fixed feed rate, real code attempts to move at what ever feed rate you tell it. (regardless of if you machine can do it or not)


check both of these

M119 is your friend for endstops
M203 sets max feed rate, M503 to view current settings.

Testcode works without microstepping jumpers, real code doesn't. They are placed below the stepper drivers.

Here is the Gcode-Wiki to read about the above mentioned M119, M203 commands.
