2.0.5.3 is limiting H.E to 230C
April 23, 2020 04:22PM
I'm unable to go higher than 230c on the hotend of my skr1.3 powered maker select. Somehow the software is setting this limit. This is for both the lcd terminal or Octoprint. I've looked in config.h and adv.h and did not find anything that would set this limit. Here is #define HEATER_0_MAXTEMP 245 so that's not it. What else would set a 230C limit?

The maximum value you can set for the extruder temperature is HEATER_0_MAXTEMP - 15. HEATER_0_MAXTEMP is defined as "if you ever hit this temperature then something is seriously wrong so we'll kill the printer to avoid burning down your house". The 15C offset is to allow for overshoot in case of bad PID settings. So you should set HEATER_0_MAXTEMP to the highest temperature you want to use plus 15.
