Description
I always wanted a larger 3D printer, but disliked how space inefficient most printers are. When I saw SilentMobius's MaxXY mod based on the ZeroG Mercury One upgrade to the Ender 5, I knew that was what I wanted.
My version allows for a 310x310mm print bed in the same footprint as the stock Ender 5 Pro. I'm not sure why this isn't part of the standard MercuryOne design considering it is just modified printed parts. It's hard to see why you wouldn't want to opt a larger print bed. BTW, the print bed I am using is from a CR-10 (I think - it came from eBay for $30).
I also created a new front tower design to tension the belts. This design works on both sides -- just flip the shuttle to align with that side's belt. It greatly simplifies tensioning the belts by having a single screw on the front that pulls in the pulley shuttle. I'm including an assembly diagram so you can see the captive screw in the shuttle and hidden M5 screw that gets installed prior to the shuttle. The tolerances are precise so you may need a little sanding to get the shuttle to slide smoothly. I think it's a much more elegant design than either the ZeroG or SilentMobius designs.
All the parts have been redesigned from scratch with a clean, minimal design aesthetic.
There are various other mods I've worked on:
I am also working on a triple Z bed leveling system, but it needs a complete redesign as it isn't working very well (z-wobble issues).
All parts were designed in OnShape, except the front towers. Those were done in TinkerCAD. They started out as a quick experiment, but they worked so well the first time, I never got around to recreating them in OnShape.
