Hi.
Neal, I had no idea that there would be so much trouble with using a ballscrew. We probably need to think of something else . . .
Our cutting table has an underlying ventilation system that could help to reduce the dust problem a little?
I Agree with you when it comes to steppers, it would be a much simpler system with steppers instead of servos, but what speed can we expect with steppers? I'll try and convince them, but they have the money and they are calling the shots.
This is how we are planning on doing it now:
Machine-control: Mach3
CAM: SheetCAM
CAD: SolidEDGE
BLDC servos with controllers from stappenmotor.nl one 750w for the heavy axis 350W for the other. Stepper for height control. ( Maybe we are talking steppers on all axis in a while if they can be convinced)
THC from either Campbell design or CandCNC
Paralell breakoutboard from campbell design.
2" ballscrew to replace the drive system on the heavy axis ( This probably need to be revised
).
Am I missing any vital components?
regards
Chris
