New build with recycled parts on a ridiculous budget 120cm*60cm work area

i think that they will be under powered especially if you are using R & P

I'm using 1604mm ballscrews (twin) on the Y, and 1605 on the X and Z. I want to build an 8*4 soonish and I think I'd like to use R&P on that for speed but since then I found you can buy commercial 8*4 routers relatively cheaply at auction or on ebay which make building one a lot less attractive.

When I bought the ballscrews I didn't know what 1604 and 1605 meant lol in retrospect I would have gone with 2010's as the price difference wasn't a lotbut then of course I definitely need the bigger motors I see cnc4you do a 4nm nema 23

I wonder if I bought 3 of these (6amp) and swapped one of my 2nm motor's (3amp) to the Z axis will 1 650va toroidal transformers be enough? If I did it I'd swap the ballscrews over to 10mm pitch to double the speed. It's unlikely I will try to mill much aluminium on this but if I do I won't be doing it in the middle lol I'll do it at the edges closest to the Hiwin's to reduce flex on the gantry.
