Firmware
Download firmware: File:Marlin v19.10.CNCTorch.zip
- To use no temperature sensors, set max temps to 500 and jumper the thermistor pin pairs. Jumpering sets temp to max, which is 358C. Result: does not work. MAXTEMP error is still triggered.
- So instead in Configuration.h:
- define HEATER_0_MINTEMP -1
- define BED_MINTEMP -1
This works. Without thermistors, RAMPS reads 0C. Set the minimum below that, and MINTEMP ERROR is avoided.
