i take it your die grinder isnt air driven

an i would have thought a fixed gantry would be an easier build

an i have nowhere near enough funds for lineear slides, so maybe i should be lookin at these instead??? http://cgi.ebay.co.uk/x4pcs-SC20-Hou...d=p3286.c0.m14

I'd want to know a lot more about that kit before I bought it. He claims 2.5A drivers then says the motors are 3A, but why use 3A motors if they cant be driven fully.

No my die grinder isnt, although i do have one.

Fixed gantry can be easier to build but needs more space than a moving gantry design. Gantry fixed in X, moving in Y, table moving in X, fixed in Y is probably the easiest combination.


You can certainly use 20mm round rail but be aware of the flex you get over any distance. a lightweight maching for milling PCBs or cutting balsa wood for RC planes would certainly be fine on a 400 x 400 workspace but anything bigger you'd be better of with these 16mm open bearings and fully supported rail
