X axis End stop is not working when the homing direction is reversed.

[adarshparavoor]

Mine is custom made core xy printer. End stop using here is optical sensor. The code that i used for the purpose is given below. X axis End stop is not working when the homing direction is as on the code given below. If i reverse this direction end stop will work. Please help me to solve this issue.

HI The direction you set back to zero is this X_HOME_DIR 1 #Homing direction(-1:MIN,1:MAX) Y_HOME_DIR -1 #Homing direction(-1:MIN,1:MAX) Z_HOME_DIR 1 #Homing direction(-1:MIN,1:MAX) That is, x and z will reverse max, y back to min direction

But you enable the hardware limit but enable xyz to be the minimum limit.

1 for Min/Max endstop enable in hardware, while 0 disable

MIN_HARDWARE_ENDSTOP_X 1 MIN_HARDWARE_ENDSTOP_Y 1 MIN_HARDWARE_ENDSTOP_Z 1 MAX_HARDWARE_ENDSTOP_X 0 MAX_HARDWARE_ENDSTOP_Y 0 MAX_HARDWARE_ENDSTOP_Z 0

Therefore, it is said that the limit does not work. For example, if you set x to max, but you are exposed to the xmin limit switch, or a max switch that is not enabled, it is not normal.

If you want to press your direction of zero return, the limit you enable should be like this

1 for Min/Max endstop enable in hardware, while 0 disable

MIN_HARDWARE_ENDSTOP_X 0 MIN_HARDWARE_ENDSTOP_Y 1 MIN_HARDWARE_ENDSTOP_Z 0 MAX_HARDWARE_ENDSTOP_X 1 MAX_HARDWARE_ENDSTOP_Y 0 MAX_HARDWARE_ENDSTOP_Z 1

If wiring, you should also connect to the corresponding interface of min or max on the motherboard.

There is also a certain direction to set the normal, as well as the switch normally open and normally closed is also set according to their own circumstances.
