Please note: The image above is wrong. It shows V-wheel, washer, washer, nut. Please view the PDF for the actual orientation. Additionally, it is not clear from this picture that an M3 washer should be used between the M3x8mm bolts and mounting plate to mount the motor.

Instructions

Y-Axis Motor Mount Plate

(This is the other side of the gantry. Pay attention to the hole orientation at the top of the plate.)

Before tightening your motor onto the plate, please watch this video.

Take note of a couple of things:

• These holes need to be on the left (opposite of the previous sub-assembly). The image shows the correct orientation.
• Each Bolt that goes through the plate gets a washer on BOTH sides.
• The smooth idlers get a total of 4 washers per bolt.
  • One on the backside of the plate
  • One on the front side of the plate
  • One on the end of the 1/4" spacer
  • One between the idler and the nut that keeps it all together.
• The image above is WRONG. For the lower V wheels with the eccentric nut, it shows, starting from the back: Bolt, washer, eccentric nut, plate, V-wheel, washer, washer, then nut. If you click on the PDF you see the correct method: Bolt, washer, eccentric nut, plate, WASHER, V-wheel, WASHER, nut.

(This is the section to add your own notes pertaining to this sub-assembly) If you run into a problem or find yourself asking a question, please post the solution here to help the next person who has the same problem/question)

Grinding out the holes 2 July 2012, Chris Lee I had to grind out most of the holes to get the screws to fit, especially the motor mount M3 screws. I have the Inventables kit from May 2012 where the plates are painted red.

Beware of overtightening the motor mount M3 screws. They bite quite well into the motor, and it isn't difficult to ruin the thread by applying too much force.

Remember to mount both the idlers in the <a href="http://www.shapeoko.com/wiki/images/thumb/2/26/Mounting_idlers.jpeg/400px-Mounting_idlers.jpeg">up position</a>, as described in step 02.

The blue line on top of the motor should be between the motor and the plate.
