Are there any plans to update the firmware to heat the bed during calibration? Just wondering, since the instructions say to have the bed heated for calibration.

I’m going through this now with calibration hell. If you connect the printer to your computer, then you can manually heat the bed and it will stay heated during the calibration routine!

The rumor have it that the current running through the heater can affect the distance sensing of the prox sensor.

So i like to pre-heat my bed to 5 degrees above temp for about 10-15 minutes than do calibration

Someone is also looking at a firmware mod to turn the heater off between each probe and back on again. (that would really be the best answer)
