After seeing my wilson 2, a coworker decided to dive into the 3d printing hobby. He ended up purchasing a Prusa i3 mk2 and he has been showing me his prints.
I'm blown away by the quality of his prints. He prints at 0.2mm with a 0.4mm nozzle. Minimal to no artifacts on his prints. Both PLA and ABS look incredible.
With my wilson 2, I've struggled with print quality. The first layer sticks fine but the first 4 layers seem to flare out at the bottom. I use simplify 3d for slicing. I've also used his same filament and tried to replicate his settings. I've cleaned the nozzle (kit came with 0.5mm nozzle). I put new bearings on the y-axis. (I still have y-axis skips occasionally) I've lubed things up. Tried different belt tensions. (All things he's never had to worry about)
Prior to seeing his prints, I thought many of my quality problems were due to mass of the print head and print bed. So I started looking at CoreXY designs. But after seeing his prints, I'm convinced the wilson2 should be capable of similar quality prints as they use the same basic design.
Other than environment, parts, and the slicer, the other major difference is firmware. Prusa i3 mk2 has highly optimized firmware with tons of innovations we don't have. It looks like many of these innovations are making their way back into marlin 1.1.
* Try slic3r
* Buy a new nozzle
* Try to port marlin 1.1 / prusa features into wilson2 firmware
* New belts/pullys, motor drivers, smoothieboard
* Buy a prusa i3 mk2 upgrade kit and create a Frankenstein
