I would like to upgrade my esky belt cp V2(ek1h-e602) to cnc head and tail assembly. Do they make a pre assembled combo set. Just learning and I am confused on what parts will work. Most upgrades are for, I think, belt cp. Are they the same? Just crashed and thought it would be a good time to upgrade but not sure how. Sorry if this question has been asked. Any ideas would be greatly appreciated.
