Hi everyone!

I am still chasing my underextrusion problem on my Beast V1.2. I replaced my hotend with a spare and the clogging was resolved (yay). But I was still seeing basically 0 extrusion, and looking at the extruder gear- it did not appear to be turning while running a test print. I thought it may be that it was just slipping due to the back pressure caused by the initial layer. I took the DCV reading across the pot screw and ground for my extruder motor and was only getting a reading of 0.78V. Turning the pot did not seem to change anything. Please see that attached picture. Am I measuring the voltage correctly? (Note: I took the reading while a test print was running)

Thanks for any help!
