I burnt the Z- port for the Z endstop. Can I use the Z+ port? I'm using Jim Brown's Marlin firmware.
Any help to change that is highly appreciated. I know nothing about code. Sorry for my ignorance. I'm new on this 3D printing universe.
// Almost all printers will be using one per axis. Probes will use one or more of the // extra connectors. Leave undefined any used for non-endstop and non-probe purposes. #define USE_XMIN_PLUG #define USE_YMIN_PLUG #define USE_ZMIN_PLUG //#define USE_XMAX_PLUG //#define USE_YMAX_PLUG //#define USE_ZMAX_PLUG
That is to say, if the Maximum endstop ports/plugs aren't currently being used, then you could just redefine the pin used by
ZMIN (Z-) to be that currently being used by the
ZMAX (Z+), in the appropriate
pins_XXXX.h file (contained within MarlinTarantula/Marlin/src/pins/), where
XXXX depends upon which board you have (I don't know what board your printer has).
// // Limit Switches // #define X_MIN_PIN 3 #ifndef X_MAX_PIN #define X_MAX_PIN 2 #endif #define Y_MIN_PIN 14 #define Y_MAX_PIN 15 #define Z_MIN_PIN 18 #define Z_MAX_PIN 19
to become (note the change in the last two lines)
// // Limit Switches // #define X_MIN_PIN 3 #ifndef X_MAX_PIN #define X_MAX_PIN 2 #endif #define Y_MIN_PIN 14 #define Y_MAX_PIN 15 #define Z_MIN_PIN 19 #define Z_MAX_PIN 18
Then compile and reflash the firmware.
Obviously you would then plug the Z_MIN (Z-) wire from the endstop into the Z_MAX (Z+) port.
