@gorf32 is the problem when the hot end is hot, or when the hot end heater is actually 'on' (ie heating)? If you try probing with the M558 B parameter set to B1, does that help? If it does, I expect the heater PWM is causing interference. If not, I would think that the heat is causing the Smart Effector PCB to expand, so changing the reading; try adjusting the sensitivity, see https://docs.duet3d.com/en/Duet3D_hardware/Accessories/Smart_Effector#programming-the-sensitivity

No i didn't see that but i did do some searching before asking, it looks to me like what i thought connect to a heater pin i was using i think heater 6 but the doc's said heater 3 so that's the way i will try it.

Thanks

@dc42 Thanks i did get it to work was a value of 400

@gorf32 I've built my own from 1mm thin FR2 and magnetic & ferro-sheets. You can find all of it online.
If I had to build a heated bed again, I'd skip the magnetic sheet and glue the FR2 right onto the cast-aluminum heat spreader.
This stuff holds PLA very well and the part just pops off after the bed temp drops around 5°. I rarely need the flex-stuff anymore.

@gorf32 the smart effector will accept 5v
