I am at the final phase of my machine build, and I'm stumped. I need help with what's left to buy. The machine itself is complete, and really all that's left is the pc and the remainder of what goes in the control box.
Some basic table specs:
I have:
48"x60" working area
rack and pinion
25mm THK linear rails on all axes
125# gantry
(2) SureStep nema 34 1200 oz steppers for the x and nema 34 960 oz steppers for the y and z
large, sealed, air-cooled control box with a heatsink (for the geckos)
4 gecko g201x (Mauriss' recommendation)
1000w 48v 21A switching power supply
Turk proximity sensors on all axes (one set for each motor, essentially)
pendant w/ e-stop
Yet to buy:
spindle: TBD (likely a 2.2kw water cooled w/vfd ebay special)
Computer will be what is required; they're cheap and plentiful
I do intend to add a rotary 4th axis at some point, so I'm leaving room for a 5th driver on the heatsink.
That brings me to what's next - the electronics. I'm simply overwhelmed by all the options. I was going to run mach3 and thought I knew what to buy for that, but after everything I've read here, I think uccnc is the way to go, so now I know nothing. I've read good things about the UC300ETH, but I don't know how to connect that to a BOB or the drivers. Is the c67-uc300eth itself a BOB? If not, what do you recommend? How is it wired to the drivers? Is it even what I need?
My budget is do-it-right-the-first-time.
If someone could help me out with a parts list or any advice/guidance at all, I would really appreciate it.
Thank you.
