This is a draft document that aims to capture both what we’ve been told by John of Forest CNC and what we learn from actually doing the procedure.

From John:

Vacuum all the dust and shavings from every part of the machine, if necessary, use an air compressor to blow dust out of crevices.

To clean the X-Y rails:

1. Soak rails in WD40 and then run the gantry back and forth 3-4 times to really get the gunk out of the tracks.
2. Use the grease gun with the correct nozzle and grease all the nipples for the tracks. Run gantry back and forth to get the grease bedded in.
3. Repeat steps 1-2 3 times.

To lubricate the Z-axis worm gear:

1. Use 3-in-1 oil and run the Z axis up and down 3-4 times. Probably need to put a rag or something underneath so as to not drip oil everywhere.

Check the bearing on the ?axis? driveshaft

1. locate bearing (picture) and make sure that it’s still inserted correctly and is true
2. if not, remove and apply red loctite to the bearing

FYI: There are a total of 10 grease nipples; need to take photos and document for this wiki.

The CNC care kit included:

• • correct nozzle for the grease gun that is already in place under the CNC bed
  • Shell Gadus S2 V220 2 Grease
  • replacement brushes for the vacuum shoe
  • replacement knurled screws to hold the brushes in place
  • Key pin for the ?need to check with Peter?
