Hey running into a bit of a problem which I can't seem to figure out..
Finishing up my printer, had all the axis running, but my Y-axis started not working correctly. When I drive in either the positive or negative direction, the axis moves only in the positive direction for both positive and negative commands. I would consider it an opto firmware problem, but when I did some trouble shooting by changing around axis motors, the endstop does stop the axis with the positive commands, but continues to crash into the opto with the negative command. I am currently using RAMPS 1.4 and opto endstops. So far, the trouble shooting I have done is:
- Switched x and y endstops
- Switched x and y motors, Y motor worked in both directions
- Switched x and y motor, x motor worked in y spot in one direction
- Switched x and y stepper drivers, ran y axis from x controls both directions
- Loaded Sprinter firmware, same problem
To me it seems the problem could the RAMPS or the firmware. My background is in mechanical engineering so I can say much on how the failure of any wiring component could cause this communication problem. Firmware could also be the issue, but my changes to the config file match that of my working X-axis.
If anyone has any suggestions, I would greatly appreciate it! So close, but so far...
