How do you fix double belts to v-slot extrusions?
I decided to double belt all my axis and I can’t figure out a secure way to clamp these suckers at ends.

I’ve seen somewhere suggestions but my search came up with nothing.

I used double sided tape to hold the belt in the groove. I have not had any issues with it.

How did you fix ends of belts to maintain the tension?

What did you mean by double belts? Do you have a photo of your setup?

Ok so this link has 3 images, click on different links just above the image - http://imgur.com/YS5JXOw,X2Mn8ou,asl6suG#0

basically its following this idea here - http://www.makerstore.com.au/blog/v-slot-the-ox-cnc-machine-and-the-everman-belt-drive-system/

by using dual belts with lower one being fixed to extrusion with teeth facing up. It allows the second belt on top, being placed in a normal manner to lock in with the lower one and increase accuracy by …a lot.

My problem is as it can be seen in 3rd image I am not sure how to fix the belt ends to a machine. This setup in 3rd image doesn’t really tension the cable since it just clamps it.

The lower belt isn’t tensioned though, right? So the top belt is just tension with the stepper, or at the ends, separate to the lower belt.

@Chris_Brent correct

Yes. Apparently it’s supposed to be a lot better at stopping our beloved gantry from extra travel :slight_smile:
