Guys I got it! I deleted and uploaded the maslow.yaml file from the most recent firmware, recalibrated, and the problem went away. I think I might not have realized that the yaml file needs to be replaced when upgrading the firmware, so I think it was trying to run a v0.74 yaml file on v0.83 firmware. That or just completely resetting the file did the trick. Either way, all of the belts stay tight now and looks great when it jogs. Excited to make some real cuts now.
THANKS for all the help!
