Time for testing! I did (what was for me) something unthinkable, joined Facebook and spend the last week plowing through the ERC TimSav group and incorporating all that information with everything I've read here.
@dutchmonkey , I ordered flanged bearings from Amazon, at $10 it was a cheap experiment. I printed the X-Tensioner & support from the Facebook group, which seemed MUCH less prone to flexing on the far end of the 2020 X-carrier extrusion, and modified the Y-plates in TinkerCAD to add a second rolling support and standoffs to tie the end of the Y-plates together as the stepper motors flexed a lot on the Y-plates and I don't like things dangling.
@Matagami Designs, I also printed Zerok's improved cutter assembly, which relies on linear ball bearings and has no flex or slop, but is smooth as glass. Gonna be doing a lot of cutting this weekend!
