JBox

This is a CoreXY setup Designed for maximum work space minimum size.
This design relies heavily on enclosure panels for rigidity(I used plexiglass for my side panels).
Accurate cuts on extrusions
I have been using this unit for 2 years only problems have been 3d printed part failure (Printed new parts and was back up and running).
If you spring load the slides on one side the bed stays fairly level (if your bed plate is not warped).
I used 1/8" aluminum plate with a tempered glass on top.
