3D Printing Forum

Was running Cura 2.3.1

Ruby nozzle

Ultimaker PLA

Just upgraded the UMO laptop to 2.4 (since it's a disaster trying to change between printers in Cura)

What's the issue?

Oh I see, that bed needs leveling.

It's level !

Then bowden angle + filament pressure making the extrusion harder in that area. Anyhow I think is a level issue. Or, many other things XD. Welcome to 3D printing where 1 think can be many.

Well it did this print very nicely
But now on the first layer of a bracket piece you can see the gap

Well, the circles don't look good. Maybe the short belts. Also next time start with 'this is on the old umo with mxl belt/pulleys that suck legendarily' !

Well....thanks for the help.

Well, sorry if that's wasn't the kind of help you where looking for. But, as much as I would love to, there's nothing we can do to fix UM crappy pulley quality. And UMO is well know (on the forums at least) for having really really bad pulleys.

Since you passed the 200h print, (a year ago or so when you finally changed your coupler for the first time) now you are looking more and more into the print, and to get quality the machine must work with precision, and every single detail affects that. Even a 0.3mm off square affects the print, and short belts are one of the most important thing to have perfect, any backlash there affects big time the quality, but I think here and on the other forum I have talk way too much about what a horrible quality the mxl offers, so it surprised me that you didn't saw that.

Hi Neotko, I'm about to do a service to my UM2, belts pullies and possibly sliders and rods.
Where is the best place to get good quality pullies from etc?
Cheers.

Wow best quality... I suppose misumi, but that's a lot of money. UM2 pulleys are quite decent gt2. And UM can sell you the belt/slider all set.

Ofc.. you could just ask Gudo for his sliderblocks and open belts, I use it on one of printers and it really works.

For rods I would go misumi or igus, both delivered to me really nice shafts, the loose the shiny in 6months, but they work perfectly so far. I think if you google 'neoyko misumi igus ultimaker' you will find the posts where I put the part numbers for both sellers.

What about sourcing the same to improve my UMO? (Asides ship it to Gudo and let him work his magic!)
