Stepper pulley remover for the K1 nd K1M stepper motors. This was designed in an effort to remove and replace the 36t pulleys on the stock steppers, this resulted in a shift that lowered the threshold of VFA from ~250mm/s to ~175mm/s.
We added 20t pulleys to replace the 36t and made the following printer.cfg changes as a result:
Rotation_distance: 40
Microsteps: 128
run_current: 1.4
Hardware Required:
- 1x M5x50 bolt
- 1x M5 Nut
Notes:
- This is meant to pair with a new gantry, the stock gantry will not properly work with a 20t pulley, but you can use a 28t pulley instead and configure the correct roatation distance.
- Slice with heavy gyroid infill >50% and many wall loops
- Go slow and use lubrication if needed as to not heat up the bolt/nut
- Tested with PLA only thus far
