Newbie looking at 6040 (China CNC) for polypropylene 15mm sheet

Going off what people said, higher voltage the better? So close to the max of the drivers.

As for the drivers, http://www.zappautomation.co.uk/elec...ion/em806.html (buying direct from manufacturer in China)
Steppers, http://www.zappautomation.co.uk/elec...ion/em806.html

Those are 80V drives so run them at about 68V to allow for the back emf. 24-24 v in series = 48 = about 68V dc when rectified.

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

A 625 va trans former will be fine good choice on the AM882

Doing an order from TME already, saw they sold toroidals.

Though it is 600VA not 650VA.
That extra few watts going to make much difference?

That will be fine

That will be fine

Awesome! Thanks.

And my caps came yesterday.

Might as well shove all 5 on?
