Hi-

I'm looking for some reccomendations on how to handle this bed heating situation.

Running 3/8 aluminum plate with silicone bed heater with internal thermistor. This works well for intial heating responds well to PID tuning. However, the linked thermistor to Duet3 control is attached to pad which is on the underside of 3/8" plate.

It takes about an extra minute for thermal flow to reach top print surface through plate. When starting prints the bottom of plate is at correct temperature but top of plate is not.

Is there a way to have another thermisor on top of plate control when print should start? Only start. For efficiency of pad heater i'd like to keep internal pad thermistor controlling the PID routine.

Any thoughts on how this could be accomplished?

  hmmm interesting, just getting used to this forum.  Nice touch code sniipit is automatic if tabbed in! cool feature

thanks,
