As delivered, the Boots Industries V2.5 delta-style 3D printer was barely usable:
- The glass build plate was warped.
- The wire based axis drive system was doomed to failure; the wire either broke over time or ran off the spool.
- The hot end was so-so; printing ABS was probably beyond it's capability.
- The heated bed was totally underpowered.
- The heated bed lives on a sheet of wood. Good grief.
- The bed alignment gadgets are plastic, and deforming over time.
- The extruder was both underpowered and tended towards slippage.
- The axis drive circuits were underpowered.
- The top deck was made of some sort of brittle acrylic sheet, which was very prone to breakage.
- The axis sliders were apparently intended to do a dry slide, which was only marginally functional.
Why keep on with something with so many things messed up? Well:
- To build the machine I had in mind originally, it would have taken me at least a year of flailing about to build a prototype that worked as well as the V2.5 out of the box.
- There are many things that they did right with this machine.
- Everything I fixed was part of an education on how 3D printers work.
For starters, I'll concentrate on the 3D printed parts that I designed and built to repair and upgrade. If there's any interest I'll write up the rest of the work I've done, and am contemplating. I think it'll work to do this as log entries - haven't done this before so we'll see. :)
About the pictures and illustrations at the top - the first pic is of the machine as shipped. The illustrations are of the various designs I printed to do the upgrades and fixes.
