Hi all,
I recently began having some severe underextrusion issues. To make a long story short, after flashing new firmware I forgot to set the e-steps to 492.45 per the Bondtech instructions. It had been so long since I had originally installed the Bondtech that I forgot about the e-steps and even after reviewing the instructions many times, I somehow overlooked it.
Big thanks to Smithy for quickly finding my problem!
