I hope someone here can help, because I am stumped.
Monoprice Maker Select i3 Plus
Printing through USB via OctoPi
Advi++ 4.0.3 ( ADVi3pp-BLTouch3-Mainboard-4.0.3.hex)
BLTouch Smart v3.1
I printed the adapter prior to installing my BLTouch and upgrading to the BLTouch3 version of Advi++. No issues at all at this point.
I installed the BLTouch and it worked, I can perform an auto level and adjusted the zheight, still no issues. However upon changing my starting script in Simplify3D, I noticed my printer is no longer extruding. It heats the extruder and bed to their desired temp as I expect, it then extrudes 3mm of feed stock. After that it moves into position and starts my print.
The issue starts here. It extrudes about 2mm of feed, then restracts that 2mm, and it does this over and over throughout the entire print. I put a piece of tap on the filament right above the extruder and it just goes up and down, up and down, never actually extruding anything. I’ve made a video to share what I am seeing: https://www.youtube.com/watch?v=ZcGVh7mWptI
Note: if I attempt my previous gcode file of the adapter (with my old starting script), it prints fine still even on the Bltouch3 version of the hex. It just doesn’t use auto-level, which is what I want here.
I’d be glad to try anything you might suggest, and provide any files you may need to help.
