Nice design, I'm not sure I can find anything wrong with it
maybe a slight tweak here and there but everthing seems to be where it should be, I like the Z axis thats how I think is the best way to do it, rails top and bottom on the gantry keeps the Z in nice and close and the wrap around connector is good to.
The only thing is wether the RC motor will cut Ali !!! engrave yes but cutting ???
Nice work cant wait to see it built and runningLast edited by Ross77; 03-08-2010 at 09:45 PM. Reason: spelling

cheers ross,,, i spent bloody ages trying to find a way to get the overhang down, i had the Y screw on the back of the gantry to kick off with but there is quite a bit of drag with the linear bearings and it seems to make sence to off set some of it with the screw at the front...... errrr if that makes sense:)

Personally I don't like the motors showing on the sides of a CNC,so I've takenthe liberty of relocating it.
This would mean its belt driven and would have to have some clearence between Y axis and rail support.

i know exsactly what you are saying about the motor hanging out and iv scratched my head over and over trying to tidy them away but at this point the design is an order parts and bolt together job, there is very little machining needed to get this one up and running... i can always make it look posh when iv got the ability to machine:naughty:
