Sorry to ask a question here on first post then answer it hours later. I solved the issue by manually setting the HEATER_0_PIN to 7 on this model. (Hictop Aurora Prusa I3) based on RAMPS 1.3 with integrated stepper controls. I accomplished this by adding the following lines to the bottom of pins.H
Also anyone looking to add a second extruder to any unit based on this controller you can set HEATER_1_PIN to 7. not sure what pin is TEMP_1 as neither of the 2nd extruder pins are listed in the pin declarations in the Marlin firmware or official Hictop Firmware
#undef HEATER_0_PIN #define HEATER_0_PIN 7
