@Sculpt-Fabricator We figured it out. one of the corners was out just enough that even though
the probe was working it wasn't probing when it thought it should be. We did a manual calibration and now
working fine.
@phaedrux We figured out that after moving it somehow the bed was to far out to out for the auto tilt to work, so we had to do a manual adjustment , fixed the bl touch code in that bed.g and led, that was in the code we had copied when set up the auto tilt that would flash when done. Thanks for your help
Will I be able to put
"M106 P3 S0" in the slicer end of print, to turn the relay off, or do I need to add something he else to the Config G?
Yes, that will work - and you can test it in advance.
That said do you need to use a fan output. If you use a heater output to control the relay (assuming your VIN voltages are compatible with the relay) then you get to have temperature control of the heated bed! If course if you upgrade to 3.1.1 and then map the fan pin to be a heater if you need to.
Alright after a lot of trial and error I have figured out what my problem was in case anyone else runs into it this seems to be working
