I went with the 20 tooth. I thinks that’s all I could find.
Great upgrades man, in my opinion the best for this machine thanks for the inspiration. If you have a minute, would you mind providing more information about the specifics of your z-axis upgrades? I’m curious about the length of standoffs you used for the xtreme solid wheels, and what ballscrew you ended up using? Are you using the stock inventables x-carve motor mount plate for z-axis? How did you go about attaching the ballscew to the openbuilds v-slot gantry plate?
