When i got my xcarve it was a Shapeoko2 with Nema 17 motors… I still have those same motors, but want to upgrade to the Nema 23s. Since inventables seems to always be out of them I found some online, but am unsure if they will work properly with the gshield… These are the motors I found… [http://www.omc-stepperonline.com/nema-23-cnc-stepper-motor-28a-126nm1785ozin-23hs222804s1-p-264.html](http://www.omc-stepperonline.com/nema-23-cnc-stepper-motor-28a-126nm1785ozin-23hs222804s1-p-264.html) ---

They will work with the gShield. Check the dimensions to see if they will fit (the Z axis could be a problem it they are too long). ---

Thanks for the reply… It looks as if width and height they are almost identical, but these are much smaller in length… 56mm vs 76mm [http://www.omc-stepperonline.com/download/pdf/23HS22-2804S1.pdf](http://www.omc-stepperonline.com/download/pdf/23HS22-2804S1.pdf) ---

@Michael5 Woah - did you see the 6mm shaft diamete on theser? That’s going to be a bit sloppy. If I remember correctly, you want 6.35mm shafts (1/4") for your pulleys. Unless your Nema 17’s were configured with 5mm shafts. Then, you’d be looking at getting new pullleys as well. Best to stick with 1/4" shafts. ---

Thanks! I didn’t notice… These are way way cheaper than the ones inventables sells also… ---

> [@Michael5](#): > > 56mm vs 76mm Interesting. The motors I got from Inventables were 51mm in length. I think there may be an issue with a 76mm motor, but the 56 mm should be ok (Z axis is the worry). ---

Even then, just flip the motor upside down on top using four spacers a spacer of your own design and it works quite well. I went with a large, triple stack nema 24 on my z to hoist my 7lb Hitachi router (but mostly because it was what I had on hand). ---

I used these when upgrading my X-Carve and they worked perfectly and are exactly what Inventables sells (when they are in stock) [NEMA23 140oz/in 2.8A Stepper Motor ¼” Single shaft (KL23H251-28-4A) |](https://www.automationtechnologiesinc.com/products-page/nema-23/nema23-140ozin-3a-stepper-motor-%C2%BC-dual-shaft-kl23h256-28-4a)
