Try using G32 to call it instead because your bed.g has M561 to clear the previous heightmap first.

@dc42 said in Runoff 3.3V on expansion socket:

My impression is that you have purchased one of the few relay boards that doesn't have optically isolated inputs; but I can't be certain form the photos you have posted. Please provide a link to the datasheet or seller's page for that relay module.

Hello, I finally choosed a simple relay board optically isolated as written in other posts here.

BTW, this is the link of the object in aliexpress

I ended up sistering a 1.5k resistor across the existing 4.5k SMD resistor for a combined resistance of 1.1k. The sensor now works correctly with all LED indicators also still functioning.

This is the Gcode command I used for RepRap 3.2
