Nema 34 upgrade issues

[routercnc]

Unfortunately yes you have fallen into the Nema34 trap. It is a common question on here asking if more performance can be obtained from Nema34 steppers instead of 23. The answer is only if the voltage is high and often mains powered stepper drivers are recommended. This can make sense on a dual ballscrew axis off a single Nema34, but otherwise they are more suited to say a big mill conversion.

Where does this leave you? Well your drivers are rated at 80V max so may be run at 70V nominal which is not enough of a step up over 48V on the motors so you are it bit stuck.

Will these motors make a future upgrade on some heavy bit of manual machinery you might have? Otherwise maybe return or sell on and fit a 70V dc power supply instead of 48V and revert back to 23s. This will give a bit more performance over the original setup.
