Could someone give me advice on whether running DC stepper drives within an AC system is Good idea or not does it make any difference? The breakout board runs on 24v ac

From what I can see after investigation the only use for the 40v is to the drivers so it wouldnt affect anything else. the 24 runs a number of other things so i would leave the original transformer in just seperate off the the new drives with a new DC transformer.

I would really appreciate some advice on it.
Ok Transformers are AC not DC If you are going to use EM806 drive 68v Dc would be good.
