Thanks Netko. Sorry I always get confused with the jungle of parts but sorted it.

will order from robotdigg

4x  606mm closed-loop gt2 belt

10x GT2 Pulley 20 Teeth 8mm Bore

2x  202mm 2GT-6 endless belt

2x  UM 20 tooth 2GT pulley 5mm

As the thread said.

But atm my printer dont do perfect circles etc so it may be wrong when I need

new x - y blocks.  only have pla what do u recomend?

 

And if you mean umo/umo+ belt upgrade (something you haven't clear) then it's 6mm wide, the length it's in the posted link (tooth = length)

PLA works nice for the side blocks. Read all the posts from that first link. They explain all of it, that's how I learned to do the mod, and works quite nicely.

Btw that bad circles might mean that you need a belt tensioner. Check the belts, they don't need to be tight, but just not loose. The guy that designed the side blocks has also a small tensioner addon for mxl belts that worked nice for me until I changed all to gt2.

hm weird after a few prints today I managed to get some better circles. Dunno what happened to the machine.

Started to experiment in sketchup with rings to fit A 10mm drill axle. First tried 10mm didnt work. Then 11 abit vobbly.  10.5 too small . And finally I thought 10.75 yes its A perfect fit.

Also first time attempt for me to make something bolt on. And it sits tight. :)

anyway this is my default tension

pushes them untill it says stop. Do I need tighten ?

There's a point where too much tension also give problems. I think on ultimaker wiki there was an old article about how should the belts 'sound' to check the correct tension.

nice but tons of informations getting headache. Can u link the items you bought?

 

The best shafts you could get are from Misumi, I bough enough for my 3 machines, they move like silk and they are perfectly straight. Ofc, unless you have a banana shaft, isn't necessary.

Oh lol, I did bough some to IGUS... Well I have a shaft overstock, hopefully someday I'll make a fourth umo...

This are the part numbers for Igus linear shafts that I got.

SWMH-08 2,00 15,34 CF53-Welle, 8mm, h7, gehärtet,

L=337 mm

SWMH-08 2,00 15,34 CF53-Welle, 8mm, h7, gehärtet,

L=348 mm

SWMH-06 2,00

15,34 steel shaft, 8mm h7 hard- L=267 mm

Their prices are around 5€ for each one, so it's almost a 40% cheaper than misumi. I have them in a box stored, the only ones I tested are the 6mm hotend x/y thin shafts, they work quite nice and they where perfectly straight, the other shafts I don't know since I didn't even open the box.

I made a small conversion for the wooden blocks to allow gt2 belts.

The mxl ones didnt move anywhere so gt2 will definitely be held in place.
