V Rail covers and brushes - ShapeOKO

Post by CreativeR » Wed Sep 16, 2015 3:25 pm

Hi all, I have an eShapeOKO (the european version of the shapeoko) and whilst trying to figure out the best way to stop debris from getting on the wheels and rails I came up with some covers and felt brushes. The covers enclose the V wheels and the brushes rub along the V rail to push any debris out of the way. I don't know if anyone else has tried this approach so I thought I would hsare the idea - images below and on facebook: https://www.facebook.com/creativeroboticsImage Image Image

That looks very practical! Do you need to clean the felt often?

Wow, I like that. I've been thinking about bellows for my S3, but these felt wipers are probably just as good.

This is one of those "Why didn't I think of that?" moments for me. Very cool. I have felt and thick HDPE, so I'm definitely going to do this.

I really like this idea and the only improvement I would make is to use a clear material so that I could still see what's happening on the wheels and pulley (without removing things). I do like to visually inspect things before every run.
Great thinking though!

Hello,

Nice work. I wanted to do this for months now. Still couldn't find time to work on it.

I have only just installed them so I don't yet know how well they will work or how long they will last. By making the brushes as separate bolt on parts for the covers I should be able to easily remove and replace them if they wear out. I had initially tried making bellows out of some ducting from a tumble drier but it didn't work out very well. I've also only done this for the upper rails and wheels because debris will tend to fall off the lower ones but static can make plastic debris stick to the lower rails as well so at some point I will do those as well.

I think if I was going to make any modification to the design of the shapeOKO it would be to give a few mm clearance around the V wheels on the metal plates, and some extra holes so that you can box in the wheels more easily and neatly. As it goes my brushes and covers shorten the range of travel for each axis by about 8mm which isn't too bad.

Very elegant solution to a continuing problem.

That is very nice! I snapped an X-axis belt last night while milling foam, because the foam clogged up the rails enough to cause lost steps and eventually drive the x-axis carriage into the end. Modified my dust collector and added that back to the system to allow for cutting but this would be a more permanent solution!

Good point on the need for more clearance between the edges of the plates and the v-wheels. I'll add that to my new plate designs.
