I use "Z_TILT_ADJUST" in my Start GCODE: ;----------Proforge 3.5 Start G-code---------- G92 E0 ; Reset the extruder motor. G28 ;Home Z_TILT_ADJUST ; Level the 4 Z motors. BED_MESH_PROFILE LOAD=mesh_60c G0 F8000 X120 Y25 Z0.80; Move the nozzle to the front edge. G1 F4000 X260 E20; Prime the nozzle. G0 Z0.2 ; ----------Proforge 3.5 Start G-code---------- Does it adjust each Z-motor to make the bed level? How close will it get the bed to level? Is the adjustment persistent?

I found that on my Proforge 3.5 the servo ground wire was connected thru the add-on relay. The servo motor was trying to send current backwards thru the signal connection. This caused the servo motor to heat up and stop working during the ARM_INSTALL macro. I Bypassed the relay (out of the circuit) and ran the ARM_INSTALL macro which left the servo motor power on for 24 hours. The servo motor was cool, as it should be. The servo connection on the BTT SKR 2 board matches the connector on the servo motor, ground, power(+5), & signal, Brown, Red, & Orange. Happy Printing!

I am getting ready to start my "first print" just to find that my DSH is not fully switching anymore. As it turns out, the black servo arm (or servo horn) is stripped out where the arm connects to the servo (there seems to be some oil leaking from the servo). I can't just buy this black plastic arm; I have to buy a whole servo to replace it... Which isn't a huge deal, as they are cheap enough. But I have no confidence the replacement won't end the same way! I've emailed Makertech and am waiting on an answer. In the mean time, I have counted the splines on the servo, to 21T, and I am hoping to get a 21T aluminum servo horn to fit inside the red ABS cover (not really sure if I can get one that will mount to the MG90S, as this is such a small servo, it doesn't seem to warrant aluminum attachments...) Does anybody else have experience or suggestions on this problem? Servo replacement suggestions? Servo horn suggestions? I feel like this servo is a problem, and I'm not the best way to remedy it at the moment.
