I have been working on my Prusa i3 Rework and have ran into some issues.
X&Y Axis
-The motors do not move the distances instructed in the host programs one direction, but do the other. I.e.moves 1 mm to max limit, but only .4mm to the minimum
- The motors will only move .1 or 1mm when instructed by host software. When instructed to move 10mm they move very little (3mm?). At 100mm the motors just buzz.
-Homing Results in buzzing. Repetier homed the X&Y properly, but at very high speeds, not sure if it is supposed to be that quick.
Z axis
-Same issues as above except for 1mm,10mm, and 100mm distances.
All of the motors buzz when they are not moving the distances needed for time associated with movement (short buzz- 10mm, long buzz 10mm)
My printer has the following working:
-Endstops
-Hotend + thermistor
-Heated Bed + thermistor
-RepRap discount Full Graphic Smart Controller
-Fan controller
I am using the following:
-NEMA 17 motors holding torque of 76 Oz/in
-T2 Belt with 20 tooth Pulleys for X&Y axis
-M5 Threaded Rod for Z Axis motion, 1 to 1 ratio motor to rod
- Arduino Mega 2560 with Ramps 1.4
-Latest Marlin Firmware
-Currently I am using Octoprint as my host software, but same problems using Repiter or Pronterface
Please not all of my motors are operational and work with the Ramps 1.4

This is my first time building a printer,thank you in advance for any help!
