Right? They are nice for hiding wires within the channel as well which is how I have wires running on the 3D Printer pictured above.
This definitely made it much quieter! I still hear it from time to time depending on the feed but it’s acceptable now! I appreciate the tip!
I was printing some dust guards for the sides to keep the belts and rails clean but the print time was crazy with the big printer being down. I had modeled up some to cut out on the x carve then realized how much easier it would be to just cut and drill holes in the 1/4 mdf I had laying around! Not everything needs to be CNC’d 
Just hit it with some black paint and cleared and was good to go. I’ll add one across the back as well just to keep it clean back there.
To get clearance to go to the height of the drag chain rail(as high as I could go) I had to reverse the screws for the pulleys. Also gave me a chance to add the extra shim.
There’s not a lot of clearance but…it’s enough!
It definitely helped keep the belt cleaner! much easier on the clean up as well. Not that it will need them after the dust boot gets here but it took a whole 30 minutes to cut paint and drill (less dry time) to do. I’ll post pics of the project on the waste board later, this is just to show the guards at work. The T-Square also worked out better for the stop block than the prior one I cut out of 3/4 ply.
Here are a few pics to show the tram, I’m really happy that it came out so dead on the first time. No lines to clean up.
The only place I have noticed them really is here on this rectangle when carving out an organizer for bits. (top right)
It’s mostly complete at this point but I still plan to do a few more add-ons and upgrades so I’ll keep updating as things progress on the x-carve (and on the work table if anyone is interested, just let me know!).
