UMO+ X-Y-Axes - Protruding axes, difference to UM2+, your experience?

Recommended Posts

Hi,

due to some other planned modifications I've to create a CAD-Assembly for my UMO+ (no assembly in github). For the axes it was easier to take the assembly from UM2+ and modify it to UMO+.

There i realized that UM2+ uses different bearings - F688-2RS instead of 688-2RS. The difference is a step in diameter.

In combination with some spacers between the pulleys and the bearings it seems for me that axes-protrusion is a much smaller problem on UM2+.

I already tried the adjustable beraing caps but there is a lot of abrasion, so I'm thinking about an other solution. Of course it is not an all-day problem, but I never want to care about this any more!

So guys who own an UM2+ - do you have Problems with axis-protrusion too? How often, how severe?

UMO+ guys - how did you manage this problem?

Would it be a solution to use thrust bearings? Miniature bearings like F3-6M or F3-8M would maybe also fit in an axis cap, if one side is adjustable with a screw you'll get no clearance and no protrusion anymore....

We will see...

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
