It’s been a few years since my reprap’s journey began, and I think it has reached the conclusion, before a total overhaul and replacement of the frame (3.0?).
I replaced the 45° rear frame brackets with slightly better ones (used a bit off-label — I’m just bolting the frame part to a table) that mount to where I had originally intended the supports to go, decided to see if the hype was real and swapped my worn out three year old belts for real, live Gates GT2 belts, replaced the original y-axis mounts that made it impossible to remove the y-axis without getting under the printer with metal brackets that are accessible from the top, and swapped the y-axis parts for the Wilson II y-axis.
This resulted in some slight improvements in print quality (mainly in y, since the original belt was really worn out and there was a ton of backlash… not helped by my super misaligned belt line), but nothing major. Worth the effort if only for the y-axis not being awkwardly mounted and impossible to remove, and the control board being in a better position.
At this point it’s clear that the 2020 frame is too flimsy for a printer of this size… as such, I’m planning to design a new frame inspired by the Prusa i3 MK3 Bear Frame Rebuild, but in openscad instead of a proprietary cad program that doesn’t run on GNU/Linux (still debating continuing hacking on the pre-MK2 community version of the Prusa i3 or just re-forking the mainline Prusa i3 MK3).
A quick and probably meaningless rough history of changes to the machine, that I want to expand into a page on my actual website eventually (more naval gazing?):
- 1.0: Straight Wilson TS, with a 300x400x300 mm frame, an itty bitty double flex extruder, and 10mm linear rods for the y-axis.
- 1.1: Swapped the threaded rod for a lead screw on the z axis
- 2.0: Upgraded the linear rods on the x and z axes from 8mm to 10mm
- 2.1: Upgraded to a Panucatt Azteeg X5 GT running Smoothieware (great hardware, adequate firmware).
- 2.2: Fixed bug in z-axis that was causing the motor mount to shift 2mm vs the x-axis parts (perils of using two different source trees for different parts)
- 2.3: Swapped the y-axis for the Wilson II y-axis, replaced the rear frame braces.
