Y Axis Engagement


  1. Remove aluminum plate pictured here.
  • 2. Loosen the 4 mounting bolts on the plate circled below.
  • 3. Push the pinion gears into the gear rack further, gravity should do most of the work but could use a dead blow hammer.
  • **Note if the gears don't seem to match up to the rack that good, you may need to loosen the drive shaft on the Y axis motor gear box.
  • 4. If necessary to loosen drive shaft you need to access from panels here. Remove the bolts and panels.
  • 5. Loosen the six Allen wrench screws to loosen the drive shaft. Once the pinion is set correctly tighten them back up.
  • 6. Re-check backlash again once everything once everything is tightened backup.

X Axis Engagement


  1. On X axis loosen 4 mounting bolts and push down into gear rack further.
  2. Tighten mounting bolts back up and re-check backlash.
