I Fixed the Noise issue with the smart effector thanks to this:
https://forum.duet3d.com/topic/5552/noise-from-heater-triggering-z-probe/9
I added a B1 to the M558 in the config.g. This turns off the heaters while probing. Now I can run the bed leveling as part of the print! I'm also playing around with the Z trigger. A -0.3 gets me a layer firmly attached to the bed. I'll measure when its done to see hoe close it is to the specified 0.2mm.
I also fixed the extruder slipping by turning up the current for the stepper.
