CL-6560 Gantry Wiper Covers

When I received my Fox Alien CL-6560 CNC Router it came with 2 broken gantry covers. Thus I wasn't able to keep the plastic guide wheels clean when in use.  The problem got really bad when I started cutting Aluminum parts. Chips started to embed into the plastic wheels and affecting the travel of the X and Y axes.

This is my design of a cover that matches the same bolt holes while adding a silicone wiper instead of brushes like the stock parts that came from the factory.

For the wipers I cut them out of a 12"x12"x1/8" sheet of silicone rubber gasket material from Amazon. If you are fine with black wipers, you can safe a few dollars here. Use the picture included with this model as a guide. I found it was easiest to clamp the sheet in a large vise and cut with a razor knife.  That gave me the cleanest edges and helped to keep things square.

I put cable holes on both sides so the same part could be printed for all three locations. Simply orient the cover in the way that causes the least amount of stress on the limit switch wire and plug up the other hole with the included plug.   If you haven't added a Y2 limit switch yet, print 2 plugs for that cover. 

Finally, I believe Fox Alien used a similar design with the newer 4040XE Pro units.  So I'm including the Fusion 360 file so others can adjust the cover to fit those units too.

Printer Settings:
PETG
0.2mm height
10% infill
5 walls
3 top and bottom layers

Print the cover on it's side to avoid supports. 

I opted for PETG over PLA because the CNC stays in the garage and it gets hot in the summer. You could certainly print this in ABS, ASA, etc…. just adjust the files for shrinkage.   The key dimension is the width between the inner and outer plate on the gantry trucks.
