changing ext0_heater_pin not working.
Hi!
I have been using my RAMPS 1.4 Z_Endstop_max pin to trigger(PWM) a mosfet module powering my heated bed for more than a year now, with Repetier firmware( thank you very much for your wonderful firmware) on my single extruder printer.
When trying to convert my only extruder heater's power supply , I have encounter problem than I'm unable to solve. What I want to do is power the extruder heater with a mosfet module trigger by one of the digital pin on the ramps 1.4(as I did to my heated bed), I tried change the pin number in configuration.h , online config or pins.h, but it seems that no pwm signal will be output to the digital pins I selected( x_endstop_max: D2, or y_endstop_max: D15) . When I test raise the temperature of the extruder, the Ramps 1.4 on-board mosfet will always turn up (D10 , also the LED4 will be bright red) instead of output pwm signal to the digital pin I selected.
I think I might be missing something, any suggestion will be welcome, thank you.
