Mounting Motors to the Ballscrews
Here are the parts that Taig provides to attach the three axis motors. Each motor is held by a tube and plate on the ballscrew shaft
and the 3 couplers have 4 holes that each take a 3/4" cutoff piece of tubing (tubing provided).
Process
- Tighten the motor coupling firmly onto the motor shaft. The shaft end should be appx flush with the coupling hole's end.
- Screw the tube a fair amount onto the end of the ballscrew shaft.
- Take the motor and place it 'firmly' against the plate/tube. The motor coupling should press flush at the ballscrew coupling before the motor reaches the plate. If not, screw the tube on more.
- Unscrew the tube while keeping the motor flush to the tube end until the gap is about 1/16".
- Tighten the collar setscrew. The collar should be flush with the end of the tube pretty much and the setscrew pressing on the tube to hold it against the threads.
- Put the motor down.
- Cut the 4 pieces of plastic tubing so one end is a bit pointed.
- Insert the flat ends of the plastic tubing into the 4 holes in the ballscrew coupling.
- Push the motor against the plate again, now ensuring the plastic tubing enters the motor coupler holes and the two couplers are at a 1/16" gap.
- Tighten everything up.
