After many people urging me to do so, I decided to rename this machine from Prusa Mendel 2012 to Ronthomp Mendel. I appreciate all the encouragement and support!
I've made quite a bit of progress. It's slower when you design as you go!
I am incorporating new designs of my own, but also the best of what already exists. Some with minor modifications and some as is. Whatever is best for the design of this machine.
The different colors are due to the age of the design. The red parts are the oldest I printed, the white are the newer.
When I first got the bearings, I thought they were crap. Noisy and jerky as hell. Then I bought some 8mm drill rod instead of the 5/16" ones I had. The difference was astounding. Much smoother. There is nothing wrong with the PLA bushings except they wear out. The linear ball bearings should last much, much longer.
Several people have expressed an interest to support my work, so I have included a paypal donate button.
It's hard to see, but the Y axis motor mount has an arc where it mounts to the lower threaded rod. This adds a much needed way to easily adjust the belt tension as the belt stretches over time.
One nice thing about the linear bearing holders, both the y axis table and the X axis carriage can be snapped off and on. The holders have provision for zip ties, but it looks like they won't be needed.
I am hoping to sell parts in the future. I have started a new web store at printed3dparts.com. Not much there, yet. I have to learn how to use Zencart.
