Hi, I was installing the e3d hotend with a new heater cartridge and thermocouple. I think I accidentally changed the pin number for #define HEATER_0_PIN. I have it set to 8 right now. is this correct? the hotend is not heating up right now. thermocouple is working fine and I checked the resistance on the cartridge came out to 6.7.
Thanks
Not sure what you have for hardware or firmware, but I believe the typical Marlin/RAMPS config is as follows:
HEATER_BED_PIN 8
HEATER_1_PIN 9
HEATER_0_PIN 10
It can be tricky to work through the #if #else #endif logic. Always check to make sure no more than one definition is assigned to any pin for your specified motherboard type.
it is a rambo 1.2b board with marlin firmware. Forgot to include that in there.
Then I believe the mapping should be as follows:Quote:
