My Y-stepper has problems: 1) the output side of the flexible coupling is missing both screws (yet somehow, it doesn't slip. mostly), and, 2) one of the jam nuts has become un-jammed, resulting in meh backlash.
How to I get access to the y-stepper coupling?
- from the front is a No.
- from the back: remove the electronics box (there are two boxes actually, stacked), which requires disconnecting 10 or 15 wires, and removing some big iron bracket... but this still looks like it will provide poor access to the y-stepper.
- remove the 4 giant cap screws holding the z-axis on, and get myself a hoist, chisel throught the 1/8" thick paint, and lift. By my reckoning, the y-stepper and all couplings should be lying there fully exposed.
If anyone's done this, please let me know.
