With the 3D printed brackets the 15T pulley on the stepper lines up with the 48T stepper on the worm drive shaft. One thing, the 48T pullies are wider than the original cogs and rub against the bearings on the worm drive shaft. So they need to be filed down a bit (see first pic). Now there’s a gap to the narrow part of the shaft which sits inside the bearing. I also replaced the bearings with some nice new 608 sealed bearings.
Next will be the first test run.
