Hi,
I am building a steel CNC, working area 2m x 1.3m x 0.3m.
I have:
X (2m): TWO nema 23 425oz coupled with TWO SFU2010 ballscrews
Y (1.3m): nema 23 450oz coupled with SFU1610
Z (0.3m) nema 23 425oz coupled with SFU1605
Gantry weight will approximately be 60-80kg.
All axis roll on SBR20UU blocks/rails.
Very standard setup for a large steel gantry type machine. All axis
After using the "required driver voltage" calculator provided on this forum, I figured I would need 60-80VDC drivers. After reading this forum for a while, I think I'll buy Leadshine AM882 drivers (http://www.aliexpress.com/item/inSto...258905084.html).
I have the following questions:
1. What do you think about this driver choice ?
2. Can you recommend to me a PSU to buy ?
3. I already have 24V-36V drivers and a 24-48V PSU, what can I do with those ? Can I may be use the PSU to power my controller ?
Thanks a lot for your help.
PS: I'm experimenting a proof of concept of no welding steel structure, only nut and bolted. Will tell more in a few days / weeks when design is ready :) All parts will be plasma cut. But that's another discussion.
