Oh goodie! today I received the ballscrews for the machine. In the end they cost a lot less than I first thought, I got the three for 133 USD including shipping, which took 4 or 5 days.
The ballscrews are 60, 40 and 25 centimeters in length, diameter of the screw is 16mm which I think it's overkill for a machine of this size, right? But better too strong than too weak I guess.
This are the three stepper motors I bought some time ago (second hand motors but they look OK to me). However I'm very fuzzy on how to drive them and what voltage and amperage to use for the power source, if anyone can give some ideas I'd be very happy to hear!
By the way, for the controller I'm planing to use the USB controller from Planet-CNC.com
Does this motor look familiar to anyone?
Putting the pieces made so far together, to give an idea of the size and shape of the router. I'm still quite undecided on how to make the gantry, the Y and Z axis. I have linear bearings for them, I'm just pondering on the best arrangement of elements.
