The belt idlers will be running on the toothed side of the belt? I guess they will be toothed idlers?

They not drive belt, they serve as protection to rails against chips/mist etc. Many of us use concertina folded covers.

Nice, thanks for clarification ;)

As Tom says, these are just flat belts (polypropylene webbed belts to be precise) which are acting as shields... due to the compact nature required in my case, bellows etc would just have wasted work area which is why I'm trying to be a bit more creative with shielding/sealing.

Heh. This thread continues to impress... Excellent.

Cheers!

So got a chance to make the new belt guides today.or simplicity I just 3D printed the bodies in my XT-CF20 - in this new design they don't take any real force as they are supported by the gantry arms so no need for anything stronger. Had some Acetal rod which I used this time for the rollers.

Interesting design feature. Looking forward to seeing it in action.

Great work, what 3d printer are you using?
