hey neotko! have you ever thought about including the spring-tension-mechanism - which you already discussed about a while ago here: https://community.ultimaker.com/topic/7985-umo-belt-tensioners-springs-not-documented/

Excellent vesh. My printer started to print even better. Thank you!!! You have amazing details.

V3 uploaded. Grip on umo shafts after a week test it's flawless. New um2 grip system (with m3x10 inside the belt grip part) seems to work quite well but I haven't test it yet. So far that's the last part to test to call it 'ok'.

Deto, I just got some time to check my 3d simulation and indeed the x stop won't work by default without gripping the endstop with one screw and tilting it. For me that's ok, but I think I'll design an adapter so the endstop hits even when using the um2 shafts.

Thanks Deto. One of my umo+ just half died so I'll start to dissasemble it to install this mod in the next week.

Printed one real quick, does seem to have a tighter grip. Still seems to be a bit to easy to pop it out though. Dont have time to do a real test at the moment, maybe in the weekend I can try it.

Deto, I uploaded a beyond-umoshaft-sideblocks-shaftholderV2 This has a more tight fix on the standard shafts. I think...

I was afraid of that when I did the addon. The easiest think to do its a double clamp that encloses the short shafts. Without changing the other parts. The endstop I only did basic test but since there's room to make a bigger endstop attached to the nuts I'll do that. Thanks!

I like the design though Im not sure its gonna work with the short shafts even with a tighter clamp, the sliders tilt a bit because the load is on the side, but maybe .. not sure :) Will probably try it again with longer shafts when I can get some. And the short endstop attaches just fine, its just that it should be on the other end of the blocks :D

Oh men you are totally right the holder for standar shafts doesn't have the inner more close gap of 0.3-0.5 to ensure a firm clamp. That gap it's on the slideblocks but not on the adapter... /selffacepalm

Also thanks for testing!

Oh weird. Maybe the clamp area it's too small for a secure clamp on standard shafts. I will design a different adapter for standar shafts and the endstop the small on don't works? I'll make a new one. But untill the weekend I'm full of to-do stuff.

Tried these with standard x/y shafts - didnt have much luck width it. The shafts were too loose, it wont fall but wiggles during print. Oh and missing X endstop :D attaching it like on the picture doesnt work for x-axis. Would probably work fine with the longer shafts I think
