SX3 Conversion

[1hand]

Now the first of many wiring questions.

This is the nema 23 stepper.

This the G540 drive.

I want to wire up the little db-9 plug in on the motor.

What I gather is this:

I put the 3.48 resistor across from pin 1 and 5.
I hook the RED wire to pin 6
Blue wire to pin 7
Black wire to pin 8
Green wire to pin 9


Am I close?

Now for the Nema 34.

http://www.kelinginc.net/KL34H295-43-8B.pdf

I hear from someone that I need to wire this as Bipolar Series.

Would this be right?

Pin 1 and 5 a 3.0 resistor between them
Pin 6 gets Brown wire
Pin 7 gets White wire
Pin 8 gets Blue wire
Pin 9 gets Green

Do I just twist the Red and Yellow wires together?
And the Black and Orange?

the nema 23 looks right and you definitely need to wire bi-polar series on the 34to keep the amps in the range of the gecko 540

[vlmarshall]

Yep, those are right. Go, man, go!

Wow, that's a big motor.

 

[vlmarshall]

What power supply are you using?

This look right?

Does it matter which way the color bands on the resistor face?

I'm going to be using a 48v MeanWell power supply.

Wow, that's a big motor.

Probably could use it for the spindle drive on a Sherline. :big:

Matt

 

[vlmarshall]

Yes, your wiring is right for the Nema 23 motors. No, it doesn't matter which way the resistors are.



Yes, I've thought about a giant stepper for a Sherline spindle motor, especially on the lathe... lots of bottom-end torque, exact speed control, and spindle indexing!

Any Ideas for how to attach the Radio Shack small project boxes to the steppers. "Epoxy"???? ???

Matt

 

[vlmarshall]

Cable tie 'em for now, until you have time to make a bracket that bolts to the tiny threaded holes on the back end of the stepper?

Guys,

Guess what, I don't understand any of this. :'( I can only look on in envy :bow: and wish all of you, all the best with CNC.

Maybe one day someone will drag me kicking and screaming into the 21st Century. ???

And the Black and Orange?

I would use some sort of real connection
1) twist then solder and insulate w tape or shink tube
2) a terminal block probably overkill
3) a crimp connector

Any Ideas for how to attach the Radio Shack small project boxes to the steppers. "Epoxy"Huh?? Huh?

I was planning on silicone sealer used silicone latex caulk held in place by wire ties have not cut the ties yet.
A bit of sealant around the wire will keep an possible coolant oil or moisture out of the motor. the reason to use a potting bx.

make a bracket that bolts to the tiny threaded holes on the back end of the stepper?

interesting idea.

Thanks Bob,

I Know absolutely nothing about CNC. These fine folk are helping me through it though. Baby steps, and a willingness to try something new is why alot of us are here in the first place.

Cheers Matt,

Matt, where did you find the DB9 connector with the circuit board and screw connections? Looks like a nice item.

Chuck;

First, let me thankyou for your info post on Soigeneris. Jeffery has been a big help on getting me on track. I am getting my Gecko and power supply from him.

Here's the link for the db-9 connectors:

I think there pretty darn handy for us one armed fellers. :big:

Today's goodies include the project boxes, soldering station, and a multimeter.

It's starting to look like there's a NASA project going on around here in the basement.

Here's a data base for electrical cut out templates.

[Tin Falcon]

Good going Matt and you are teaching the rest of us a thing or two as well. That cutout link could come in handy.
Those connectors are great for quick motor testing especially when one does not have a spec sheet. A gender bender along with them comes in handy also.

Matt, I'm glad you found the link to Jeffery Birt helpful.

Also thanks for the link to the drawings for the DB9 connectors. I'm working on a control box for a Taig lathe I've been converting to CNC. I'm using a G540 also. A DB9 connector looks like a good way to bring in lines from the limit switches, etc.

Chuck Kuhn

You're doing fine so far! And Thank You for the link to the templates.


Looks like you are a 'natural' at electrical stuff as well,
Kermit


Also, an alternate source for those connectors
