Adjustable belt tension UM2 sliding blocks
Adjustable belt tension UM2 sliding blocks
On the UM2 I had always found that the tension of the belts was a bit fair and especially uneven on the same axis and also between the X and Y axle, as the belts began to too much relax, here what done to improve the system while respecting the original dimensions and easy access.
The blocks can be assembled without removing anything apart from the original blocks and cut the belts which will reserve for the new blocks with adjustable tension belt, do not throw away your old straps !
Now the belts have "about" the same tension, I tuned them to the sound as for a guitar
Ofc, I will share soon after checking the all well work by some hours of printing tests

I forgot that I was inspired also after talking with Neotko adviced me to use the open belt option

ça risque de me piquer les yeux en coupant les courroies mais j'avoue le concept est vraiment intéressant !

Re: Adjustable belt tension UM2 sliding blocks
Your solution is much better than the step file I sent you, you solved the space needs to fix all. I did try that path, but I never though about using m2.5 screws, that solves all the space needs. My box of m2.5 will arrive this friday.
Short belts on the UM3 made all work much better, used some gt2 I had spares for umo+, but indeed your solution is much better. Mine was quite a pain to install, yours is easy to maintain, replace and tighten. A really great job as always men!

Hi all
Thanks!
[quoteça risque de me piquer les yeux en coupant les courroies mais j'avoue le concept est vraiment intéressant ![/quote]
J'avoue que au dernier moment j'ai hésité à le faire !
Neotko, when you will print the 4sets sliding block parts, think to mirror 2 sets, that will allow you to have the right side screw heads access
Thanks!

Re: Adjustable belt tension UM2 sliding blocks
Question : pourquoi ne pas utiliser des écrous carrés iso à la place des classiques hexagonaux : la surface d'appui serait plus "mécanique".
Je pense faire ça de mon côté dès que j'ai un écrou à noyer ou un montage à faire.

très juste ! mécaniquement ce serait mieux, le pire c'est que j'en ai, pas facile à en avoir !darkdvd wrote:Question : pourquoi ne pas utiliser des écrous carrés iso à la place des classiques hexagonaux : la surface d'appui serait plus "mécanique".

c'est plus une question de sourcing, c'est plus facile de trouver des écrous hexagonaux en petite quantité sur le marché.
members ! sorry to speak in french

Re: Adjustable belt tension UM2 sliding blocks
I don't mind. Translate google to the rescue
I bought iso m2.5 to print Gudo slideblocks. I will probably change (extrude a bit) the screw holes.
Luckily I found an ebay guy that sells m2.5 in packs boxes ready to use with 6-8-10-12-16mm and nuts for just 12€

The only French I know is the French-Canadien ('Old French") dialect. Much different than Paris-Frenchgudo wrote:

Il n'est pas un problème d'écrire en français, google translate semble fonctionner correctement.
it is not a problem to write in French, google translate seems to work fine.
