Hi,
First post on this forum, hoping it is not in the wrong spot (there are so many sub forums)
Have been wanting to build a CNC for some time, I made a drawing some time back before deciding it was to light weight and would have not held up to well against gravity.
So I have redesigned
Made from 14mm Aluminium plate
30 x 60 Extrusion
THK rail for the X
16mm rail for the Y
12mm rail for the Z
RM1605 all round
BK/BF supports
Cutting area
Approximately 100 x 450 x 500mm
Not sure of electronics as of yet.
Wanting to machine timber, plastics and aluminium, as well as engrave some other metals.
This may be a slow build.
If any one has something to say about the design of the machine please feel free to let me no.
on your gantry uprights, I wouldn't square it off and then go up for the Y-Axis. I'd angle it all the way to the top, or at the very least round the inside corner there. Anywhere you have an inside corner like that will be a weak spot giving it a single point where it will crack. Making it a circle, gives the corner more surface and less chances to form a crack.
For the electronics, as most here will tell you, for a small machine build like that where your motors won't be too big (amp hungry), buy a GeckoDrive G540. It's got all your drivers in a simple box. Just buy a powersupply, the software and motors and you're good to go.
