Y belt tensioner for FLSUN cube by GregLen

Last crawled date: 4 years, 7 months ago
Newly modified to reduce the height by 5mm.
Not yet printed and tested.
The existing mounts for the Y belts have no adjustment, and are some 12mm lower than where the belts come off the toothed pulleys - the height difference will play havoc with the belt tension. Simple Pythagoras shows a belt length variation of nearly 2mm between carriage at the centre of Y, and carriage at the Y limit..
This modification solves both those issues.
Each belt will need one Ysupport and one Ytensioner - they fit on top of the two X rod mounts, and are fixed using the M3 bolt through the mount clamping hole.
The tensioner should have an extra support on the other side of the rod holder to stop it twisting. If you use it (recommended), the M3x25 will not be long enough. Suggest an M3x30
The tensioners require an extra M3 bolt and couple of nuts (to lock it) to use the standard H Wheel Holder as in my X tensioner.
The Ysupport has a cut out on one side to enable it to fit against the X motor.
