I have been able to use the temperatureswitch configuration to get my hotend heatsink fan to turn off and on, but only after the hotend has gone above the threshold for the first time.
When the hotend is room temperature and I boot the printer, the fan immediately turns on even though the hotend temperature is below the temperatureswitch threshold. Here are the steps:
1. boot with hotend temp below threshold - fan on (can I change this?)
2. temp goes from below threshold to above - fan on (ok)
3. temp goes from above threshold to below - fan off (ok)
4. temp goes from below threshold to above - fan on (ok)
…continues to do the right thing as it crosses the threshold in either direction
Is there a way to have the fan off when I first boot the printer and the hotend is below the threshold?
