Good afternoon,
Similar to what a number of other people here have seen, I am having issues with a couple of my end stops. I am on my third RAMPS board, so at this point I suspect their hardware rather than anything else, but I'd like to run it by everyone first.
My printer currently has the following:
X stop on the right side.
Y stop in the back.
Z stop at the bottom.
Therefore it is my understanding that the following is correct:
// ENDSTOP SETTINGS:
// Sets direction of endstops when homing; 1=MAX, -1=MIN
#define X_HOME_DIR 1
#define Y_HOME_DIR -1
#define Z_HOME_DIR -1
I also have all of the pullups enabled for Min/Max and all three axes. Quick aside, can anyone tell me why you would not want to always have all of the pullups enabled? By not having them enabled you would throw even your unconnected stop positions into an unknown state:
#ifndef ENDSTOPPULLUPS
// fine Enstop settings: Individual Pullups. will be ignord if ENDSTOPPULLUPS is defined
#define ENDSTOPPULLUP_XMAX
#define ENDSTOPPULLUP_YMAX
#define ENDSTOPPULLUP_ZMAX
#define ENDSTOPPULLUP_XMIN
#define ENDSTOPPULLUP_YMIN
//#define ENDSTOPPULLUP_ZMIN
#endif
#ifdef ENDSTOPPULLUPS
#define ENDSTOPPULLUP_XMAX
#define ENDSTOPPULLUP_YMAX
#define ENDSTOPPULLUP_ZMAX
#define ENDSTOPPULLUP_XMIN
#define ENDSTOPPULLUP_YMIN
#define ENDSTOPPULLUP_ZMIN
#endif
Home positioning currently works for the X axis, but not Y or Z. They just overshoot and try to keep going. Using m119 I attempted to debug the issue. However, now with pullups enabled I can never get either of the Y or Z stops to register as triggered. I removed the wires and used a jumper instead with the same results. That rules out any installation or stop hardware issues and points the finger at the RAMPS hardware or some setting that I don't yet know about.
Any pointers or ideas for the next step would be greatly appreciated.
Thanks in advance,
Glenn
