AM882 drives would be less dosh and just as good.

Ohhh
I thought it was 1:1 from transform through rectification.
That makes sense why so many are doing 24-24v.

These are the drivers I am getting https://www.aliexpress.com/store/pro...615.0.0.9rnD8Q

Forgot I changed to them.


Am I right in saying that when the steppers start up or change direction, they require a lot of amps, but when they are going it is pretty low.
Which is why you are able to get away with lower wattage transformers?



Thanks
