Might have figured it out. I managed to find a pic from another seller with the same model but it showed them plugged in. Figured there was nothing to lose so, what the heck. Seems to have worked. I've got action on the steper. It errors out when the encoder is unplugged so, might've done it. Thank God for Google images! Lol
Anyone know offhand what the size of the ball screw is on the motor end? I ordered a 1/2" to 14mm coupler but never thought to confirm that the end of the shaft that mates with the coupler is 1/2" or one of the other sizes.
In case anyone is looking for colour coding for the encoders like mine (Stepper 86HB250-118B ), the hookup is as follows:
EB+ - yellow
EB- - green
EA+ - black
EA- - brown
VCC - red
GND - white
Might help someone in the future.
It comes with the coupler.
Question:
I have 2 of those parallel breakout boards from Steppers Online. They get their 5v from the USB port on them. They also have PC5v and PCGND terminals along where the motor terminals are. Can I feed 5v and GND INTO there instead of using the USB port? (would be much easier if I could)
If you are talking about the 5 Axis CNC Breakout Board then it depends on how you plan to use it. I had mine connected to my ESS to control my 4 Gecko drives during testing without the USB connected. The DB25 has power lines.
I know some of the inputs do not work without the 12v line connected. My guess is that the non-motor outputs need the 5v.
The BOB I'm using now is different than what I used for testing.

I ended up just canibalizing some old USB cables and put ends on the -5v and GND wires to run to PSU. Works fine.
Taking a trip out to Nate's shop this weekend for a pickup so hopefully I'll be able to start an actual build thread. Very excited!
Just ordered a cheapo laser crosshair on the eBays. Any good mounting ideas?

Quick question: to those that bought Saturns without electronics, did it come with the mounting hardware/bolts for the NEMA steppers?
Not with my Saturn 2, it comes with the cable chain for X & Y and the motors mount to the gear reduction drive but I ordered the NEMA 34 Plug and Play so that might be the difference.

Yes, they are with the drive reduction. Just double check the stepper pulleys before you leave, the ones that shipped with my table had the wrong keyway slot size and it took over a month to get the correct ones. If you’re not getting steppers with the keyway it doesn’t matter but mine have a 5mm keyway since that’s what he suggested to get and the pulleys I received had a 2mm slot. Just make sure you get everything and everything is right since you won’t get a lot of after sale support from him if any.

Noted.
Actually I already bought some 20 tooth pulleys from Ali that are 14mm with a 5mm key. They weren't terribly expensive and I wasn't sure what the kit came with. Same with the coupler for the Z. That must've been a bit frustrating having to wait that long.

Yep, and I couldn’t find them outside of ordering them from China. The replacement ones came from CNC router parts so at least now I know where to get them. I actually tried to contact them since I didn’t see them on their site but they never got back to me. If I were you I would have them unstrap your machine so you can make sure the gantry moves smoothly before you take off. I’m having to do a bunch of work to get mine not to bind up. I’m sure I’ll get it a 100% but it shouldn’t take this much work and should ship close to perfect from the manufacturer.
Have them fix it while you’re there if there’s any issues so you don’t have to try and figure it out on your own if there’s a problem. Hopefully yours is fine but mine wasn’t and from what I’ve seen on the forum there have been others with a similar problem as me. Overall I’m very happy with the machine, there’s just some qc issues Nate needs to get sorted out. I almost think my gantry was used since the paint is all messed up on it.
Any way good luck and drive safely,
Dan
