Hey guys,
I'm drawing up plans for a CNC, first time(of course!). I've got a few parts, , but before i commit to the big purchase of the electronics I wanted to see if my cart is satisfactory.
The main use of the CNC is to cut signs out of 1/4"-1/2" wood panels, and possibly aluminum , but only up to 1/4" probably, and a random chance use of <1/4" plexi/lexan. Currently looking only for 3 Axis, possibly 4th for turning legs in the future, but not likely.
Currently will run on 1 start 1/2"-10 acme rods. and 12mm bearing shafts. (with intentions of being upgraded later)
MY router : Porter-Cable 895PK 12 Amp 2-1/4-HP
(might downsize there to something more disposable)
I was thinking vendor-wise to go with buildyourcnc.com, as they had a relativity nice electronic kit. Which they have a nice site, but too far many bad reviews to risk. I've read about Keling, now Automation Technology Inc...and they seem to have a similar type components for about the same price with favorable reviews.
This is on my seriously considering list via Auto Tech Inc:
3x NEMA23 425oz/in 2.8A Stepper Motor ¼” Dual shaft (KL23H286-20-8B)
3x KL-4030 Bipolar Stepper Motor Driver, 40VDC/3A
1x 24V/8.3A Switching CNC Power Supply (KL-201-24)
1x Breakout, not sure which yet.
(3X2.8A = 8.4A...PSU too small?)
I've also seen a few all in one breckout/driver type guys out there like the one from Sainsmart: SainSmart CNC TB6560 4 Axis Stepper Motor Controller
But I'm a little leery there, I'd rather spend an extra $50 and get 3 proven drivers.
Anything here seem out of place? I'm just trying to make sure I'm headed in the right direction without too much of a hard learned lesson.
Thanks
