You can use any of the + and – ports, we choose to the ones that were right next to each other. The order for the plus is Line, Neutral, Ground.

Why upgrade?

View the instructions here: http://blog.inventables.com/2014/04/upgrading-your-shapeoko-2-with-nema-23.html

The ShapeOko 2 is compatible with NEMA 23 motors, with a few modifications to the basic assembly. The machine runs fine with NEMA 17 motors, but if you decide to modify the basic design to longer extrusions or a larger more powerful spindle you may want to use NEMA 23 motors for the X and Y axes. They will give you the power and speeds appropriate for a larger machine.

The larger motors need to be mounted on the 1/4" spacers to clear the bolt heads for the idler pulleys. You also have to avoid the bolts used to mount the X axis MakerSlide. This is done by moving the motor to the lower end of the slots or by notching the MakerSlide.

Get the most out of your motors

To get the most out of the motor upgrade, you can use the tinyG controller with the Enclosed Power supply. However, the upgrade would work with the stock power supply and gShield.

What's the purpose of the dual shaft motor ?
Shana Robinson

Hello Shana, Great question. In this application, the dual shaft has no advantages over the single shaft motors. We chose to include the dual shaft motors because we have more of them in stock. Best, Sam
Sam Alaimo

Does the dual shaft allow using the Z-axis knob?
Kuson Sintusingha

Hello, Yes, the dual shaft allows the knob with crank to fit. Although to use a Nema 23 on the z axis, you need a new z axis plate.
Sam Alaimo

One can use a dual shaft Stepper motor to put an encoder on the other side for more accurate results. Your electronics need to support encoders however.
Fritz Weinrebe

An item I don't see on this list is the NEMA 17/23 Z Axis Plate. (https://www.inventables.com/technologies/nema-1723-z-axis-plate)
Fritz Weinrebe

Why is the TinyG in this parts list? Is the Shapeoko 2's GShield unable to supply the necessary current for the Nema 23s? If so, I assume the alternate power supply is suggested for the same reason? Thanks, Peter.
Peter Govaars

Hello Peter, You can use the 23 upgrade with the stock gshield and power supply. However you get a lot more power out of the motors with the upgraded power supply and board.
Sam Alaimo

I don't see the 'tinyG controller' nor the 'Enclosed Power supply' in the parts list. However, I would like to use these! Where can I buy them? Is it a generic tinyG controller? How do I identify the proper 'Enclosed Power supply' on the webs or on this site?
Jon Loldrup

Hi, You can add those to your cart separately. If you are using the TinyG with the Nema 23 upgrade, I would recommend using the 24V 10A Power supply 30353-02. https://www.inventables.com/technologies/enclosed-power-supply https://www.inventables.com/technologies/tinyg-cnc-controller
Sam Alaimo

Do you need cut the maker slide to fit?
Pablo Covarrubias

So why does the bill of materials for ordering this upgrade say (x2) for the screws, spacers, washers, and nuts, when each motor requires 4 of each? Typo?
David Duncan

Read the description, it says Quantity 10, so you are getting 20 total of each..
Nathan P Kazier

Hi, while I am upgrading why I need GT2 pulley(20 teeth) ,the old motors also has the same pulley. Also do I need to change the mount plate for nema 23 or mount plate are same.
Prateek Gupta

is it ok to use the 10A powersupply with NEMA 23 and gshield (not tinyg)
Khalid Al-Kooheji

Hi, i already upgraded to the quite spindle, and i'm using the recommended power supply, 48V and 7.3A, would that work for the NEMA 23 upgrade?
EZG

Hi, You can use the 10amp supply with the gshield.
Sam Alaimo

Sam's got great customer service skills! ;) I'm getting my new shield today!! :D
Javier Delgado

How looks NEMA 23 on Z Axis , do I need any additional plate ?
Kacper Gogół

I bought the works kit. I plan on replace the Arduino with a 4 axis controller and add 1 more Nema 17 to system, My question is if the current power supply that comes with the works kit will be sufficient?
Nick Gannon

I got this kit and discovered that either the shaft on the motor is too short or the pulley not long enough because there is not enough shaft to get the pulley out in position with the motor space away from the plate. is this normal and I am missing something or is there a problem with the parts?
Trevor Green

@Kacper Gogó? the z-axis on a shapeoko does not fit a 23, you will need to make a plate or upgrade to the X-Carve belt driven X-axis.
Sam Alaimo

@Nick Gannon The 90w power supply that comes with the base kit should be enough but you might want to upgrade to the 30353-02 Enclosed power supply.
Sam Alaimo

@Trevor Green You should be able to get this to work with the pulley and motor. Please send a picture of the set up to help(at)Inventables.com so we can take a look.
Sam Alaimo

Even at the bottom of the slot the maker slide would not clear the button heads. I ended up using the extra spacers on the x axis. Other people may need to tap their x axis maker slide further to accommodate the slightly longer then stock bolts.
Bryant Overgard

I know this is ancient, but I'm making a Frankenstein Shapeoko- what programming changes do I need to make?
