Hello, I have the acrylic i3 Pro C. I was printing the other day and the x-axis belt came loose from the blue plastic bracket on one end. I pulled it tight enough for some moderate tension and slid it in. I'm not sure how many prints I've attempted since then, but it came loose twice today. The belt just seems to slide out axially somewhat easily (toward the y-stop).
I dabbed a little hot glue into the groove with the belt ends anchored and it's warming up for a print now. I'm concerned though. Is there a better way of holding the belts into the bracket?

By the way, it's a little too warm back there for hot glue. Looks like it began to melt after finishing a 2 1/2 hour print. It came loose again as the next print began.

I am encountering the same issue. I agree it looks to be heat related. I am looking at modifying my bracket to 'pin' the belt in place. When I get around to it I will design a new bracket though I would need a new belt to use it.

I was in the middle of printing when it came loose the last time. I inserted a couple of short pieces from a tooth pick to wedge the cogs of the belt into the grooves in the anchor. It has held ever since.
