Possibly, although the voltage he filled in was 2.1. And it is a three screw cover whereas mine is a four screw. I had one opened up because of some condensation that had started to cause some rusting and seize the armature, but had not got to the bearings and I was able to free it up. The wire is no16 in excellent condition and would be about what I would expect to handle 9 amps.

Must be wee hours there, I'm in Reno, NV.

I think the voltage was a bit more than 2.1 on the superior or sigma motors that I originally had on the Bridgeport when I first got it but also what you have to remember is with the likes of Geckos you want to use around 20-25 or so times the motors voltage so even if they were 2.1v you are still looking at about 50V.
 When I did mine I already had a POS manual Bridgeport that I had converted so I took the motors off of it and put them on the BOSS, then sold the originals on eBay.

Its not too bad, just gone midnight here :)

Just a quick shot with a crummy cell phone :D.

The guy you want to contact about these is John Stevenson, he has done a couple of them with the original steppers and geckos. I think he now uses the Leadshine drives as they have a model that can handle 9Amps.
Might be worth a PM to John, heres his profile info

I installed a VFD for the motor and started it for the first time. Typical variable speed belt and pulley noise, but spindle bearings are quiet.
I downloaded trial Mach3 and installed it on the dedicated computer. I have been through the tutorials waiting for the Mach3 control box, and all that went as described in the videos.
The Mach3 box came in from Campbell Designs yesterday so I will start wiring.
The limit switches on X and Y are NO micro switches which can be each be connected through a single two wire cable.
The Z has two micro switches for limits and a single push button micro switch at the top for the home. I can wire the two limit switches to a single connector, but will need an additional cable to include the home. As I remember in the tutorial the home and limit may be combined. Should I keep home separate on Z?

If you have enough inputs just keep the separate switches but if possible best to wire them normally closed as that means if a wire breaks then a limit will be seen, with normally open the first you will know of a broken wire is the axis flying past the limit and not stopping.

I got the Z axis to cycle and started tuning the motor without limit switches.
I will have to separate the circuits because as supplied three of the connectors are for the the X.
I'll see about changing to NC when I go out tomorrow.

I posted in what you made, but the question might be have more exposure here.
I picked up a rotary table on Ebay, but it is servo driven.



My plan is to convert to stepper since I have the fourth axis Gecko in the Campbell box. I haven't been able to sort out the NEMA numbers for the mount. From what I understand the number is based on the bolt flange center to center distance. This mount mics at 1.100" so that would be NEMA 11, but when I go to catalogue cuts the numbers do not coincide. Any thoughts? the shaft is 6mm.
