I was wondering what everyone's take was on the linear bearings that support the x and y-axis.
My previous experience was that they get gummed up once in a while. I thought it would be interesting if they floated over the guides like an air hockey puck. Curious about what others thought. It might be a wasted effort, but it'd be pretty easy to add an airline and some holes to a rod, with the result of potentially removing any friction on those axis.

I use Linear bearings on all my kossel machines, so there is 3 per machine (I use the 15mm size for the 1515 extrusions.. I think they are MGN9C? )Quote:

Very interesting. What kind of impact does that rust have on the performance of the printer? (Maybe no more printing in the shower?)Quote:
