Hello all,
I finally got around to finishing a Mendel I had started several years ago and am very close to a first test print.
I am using a RAMPS 1.4 Board with Arduino 2560.
I am using Repetier 0.92.3
I have Opto Enstops on:
X Min
Y Min
Z Max
I am using a mechanical endstop as a z probe hooked up to the Z Min pins.
When I send something like a G0 Z10 it is only working some of the time. Sometimes the stepper motor just makes a loud hum and doesn't move. It is not consistent but about every third G0 command I send actually works.
G28 always fails on the Z axis. Just a loud hum, no movement.
Strangely enough the Auto bed leveling process works without an issue. When I issue a G32 S2 the whole process completes including the Z axis moving to Z Max and measuring the build height.
Just for kicks, I tried installing Marlin to see if it was a firmware issue. In Marlin the G0 commands seemed to work fine, but G28 still failed.
I have tried all of the following:
Swapped out the Stepper Motor
Swapped out the Stepper Driver
Adjusted the Trim Pot on the Stepper Driver
Routed Z Probe and Z Max wires far away from stepper motors and stepper motor wires
Tried running it with everything disconnected except Z Stepper and Z Max
I have attached my Configuration.h file for reference. Maybe I have something stupid in there. I am so close to having a working printer. This is quite frustrating. Any help would be appreciated.
