My Ender 3 v3 SE printer is still really new so I understand the info is limited. I'm trying to build a version of the latest Marlin FW that will work I've already redefined the pins that are different however PA4 CLK and PC6 SDO are undefined currently which is for the strain gauge or whatever they're using is a 4-wire sensor. I would imagine this could work as a second Z probe Z1_PROBE then take the difference between the Z probes.
My questions:
- How do I define the sensor pin?
- Is it baked in already to calculate the Z-offset between two probes?
