I just realized, you might not have seen above that I already had the 4.1 upgrade. So I was using the new board and encoders. Sorry didn’t catch that before the order came in.
I sent you an email @bar about shipping costs being inaccurate on the site, but will also post here for others to know that upon taking the arms apart to replace the encoders, one of the idler gears was damaged and stuck in one of its bearings. I was gentle during initial assembly, so something happened during calibration. I am going to order a new idler gear and will hopefully get this this working!
