I've got a Bridgeport Series 1 CNC with shot 3 phase electrics. I've come to the conclusion it's best to give up the original motors and go for new steppers and a complete rewire etc. I've trawled the forums for hours trying to educate myself but I'm still not exactly sure what I need. Something like this kit from Longs (https://www.ebay.co.uk/itm/EU-Free-S...4AAOSwMPxbkIMJ) which includes motors, power supplies, BOB and drivers. Longs offer different versions of NEMA34 and NEMA42. Does anyone here have experience with how many oz-in are required to power the XYZ axes on a BP Series 1? I was thinking maybe the Nema34 1200 oz-in would work but I'm really not sure?

I'm on a budget so a servo motor conversion is out of my reach, hence the interest in these relatively inexpensive Chinese kits. Thanks in advance for any advice or links you can point me to.
