Okay, so I looked into toroidal based supplies and they are easy to make. So should be no time to spin a board for one of those.
Do cost a bit to get them off the self, though I know of a place that do them for like 50 euros each at any spec you want.
So might be able to get a decent high amp one for not that much more.


The problem is, the high voltage stepper controllers are not Chinese cheap :p
Looking at £110 per axis :/

I have only looked on Zapp though so far.

Steppers themselves are around £30 each. Makes it around double the cost.
But I guess it is worth it because of needing that extra speed and power?



Regarding the steppers, they state a "Rated Voltage" of around 2-4v.
Do the drivers lower to voltage or because they pulse the stepper they are able to use upwards of 80v?
