They have a 3D printed rack reinforced with an M6 threaded rod, and some other good features. Have a look at my video review:
awesome Simon.. I'll txt you next.. I defo be interested in having one off you.. this is all brand new to me.. but got to start somewhere.. excellent video review.. and really good product.. nice printer by the way.. I need to look into buying one at some point.. that's one of the modules on my 3d printer course I'm doing... seems to be the way to go nowadays..
