Finally built something with some of the MakerSlide that has been gathering dust for the last few years. It's one of those vanity projects, of the "I wonder if this could work" variety.
How about a CoreXY printer, build volume of 12"x18"x18", made from ABS printed parts, MakerSlide, PVC pipe, and about 500 sheet metal screws?
Here you go:
Still working on the first print; I'll calibrate the machine later. I've learned that it prints a whole lot better if you tighten the grub screws on the XY motors.
