Dust protection - Rail cover

Post by Digitalmagic » Sat Jun 23, 2012 10:12 am

I wait for my shapeoko with the same syndrome!

I thought about dust on rails after seeing several videos with shapeoko in action.
Here is a U-shaped shroud idea.
It is obviously simpler for Y axis, but perhaps a smaller plastic cover below the gantry could help reduce dust projection.

An alternative idea is to add a suction cone linked to a hose ending with powerful silent fan, with a filter.
I thought about this to 3dprint ABS, and remove the smelling/fumes.

There certainly seems a need for something like this DM, one only has to watch the demonstration videos to realize the dust problem is significant. Well done. :D

The covers that I made from plexi worked out pretty well. You can see a video of them in action here:


At some point in time I removed the rails to make an upgrade, and forgot to put them back on before bolting the front plate back to the assembly. Instead of taking it apart again, I went with some packaging material and duct tapped the bottom for a proper 'seal'. You can see that here:


It seems the packaging material + duck tape solution works quite well, although doesn't look as finished as the plexi guards.

I think ultimately a set of bellows for both Y axis rails and the X axis is the answer. I've yet to buy a set because I can't find any that are reasonably priced and I've yet to build a set because most craft projects are beyond my capabilities :-)

Just as a reminder: The guards aren't necessary if you're cleaning your machine after each run. And by cleaning I just mean blowing it off (shop-vac in reverse). But, if you're running multiple jobs, or don't feel like cleaning it off, some solution will be worth your time / effort / money.

Indeed, I think bellows are heaven better.

The dust cover could be directly bolted on the Makerslide like this.
I already have some thin alu sheet, easy to shape, before trying something transparent.

I would like to submit the idea to have gantry bottom V-wheels positioned inline with the Z-axis V-wheels.
This would increase the X-axis possible travel, for a given shapeoko footprint.
What do you think?

And we add the new X axis plates, great! :D
