SN-04 sensor inconsistent
July 22, 2018 11:00PM
I am running an SN-04 sensor on an Ender 3 powered by a Re-Arm. Board and sensor voltage is 24 Volts and version is Marlin 2.0.C bug fix.

I am getting inconsistent readings, even though I used 2 different sensors. The leveling data does not make sense. I leveled manually then did the auto level.

Are sensors affected by power wires in the bed? I noticed the left rear corner is the worst. I increased the probe edge to keep it away from the wire and while that did help a little, it is stilll not great.

Any tips?

Inductive sensors can definitely be affected by the current running through the bed heater traces. Try enabling PROBING_HEATERS_OFF in your configuration.
