Hello everybody,
I started to design a desktop mill based on pocket NC and robotdigg just for fun but now I'm wonderning if it would be possible to actually build it.
Curently the machine is roughly 450*450*570 without the enclosure
Here's what I want :
- High dynamic
- At least .01 repeatability
- High rigidity
- Process aluminium "efficiently"
- An enclosure for coolant
- Steel frame
- 100*100*120 working area
I have a few years experience in 5 axis CNC machining but absolutly nothing in design nor electronics so I could really use some advice on few things :
1) I overlooked all the calculations needed during the design process so I used placeholders for the spindle, servos and the belt and pulleys so i need some guidelines to properly size the servos and ballscrew
2) Do I need to make a proper bed or bolted steel plates can work ? I think I need some weight
3) Do closed loop servos need home switches ?
I forgot to mention but i don't intend on making this build profitable. It will take the time and money needed.
