Thanx Jazzcnc for advice and comments :-)
And yes, i am a member of CncZone as well. There are some Norwegian members there, and i like to hear all those different opinions ;-)
.
Ok, it seems i was a bit offline when i replyed to the thread. Mentioned KL-8056D but provided a link to KL-5056D.
I did send Automation a mail last night asking why the they list KL-8056D for "up to +7Vdc", when the datasheet say +20 to +80Vdc.
If what i have read around is correct, the KL-8056D is a re-badged Leadshine DM870. And Leadshine says +20 to +72Vdc in their datasheet(found that out today)
Dissapointing and very confusing, but this fact eliminates the KL-8056D.

Tried to find a price for the AM882 and EM806 and they don`t come cheap. Found some new AM882 at a reasonable price though and may decide on them.
What about the MA860H? Does anybody have any experience with the MA860H ?
Leadshine datasheet says input voltage of max 80Vac or +110Vdc, 7,2A. Price 58,88 on steppers-online.
.
I do have a lot of experience with PSU(both switched and lineary) Jazzcnc, and having a larger than necessary PSU only ensure less voltage drop at high loads.
Besides i want to have enough for the 4th axis.(might even put in the 5th axis in time if i get if i get excessively geeky).
And beleive me Jazzcnc, i have searched the entire Norweginan marked for parts to build it my self. That will cost me twice as much.
.
The reason for me choosing Nema34 motors is only because it has Nema34 motors originally. (Lacy me, don`t have to manufacture new mounting brackets)
.
Final thoughts with renewed thanx to good advice from Jazzcnc:
Stepper drivers.
AM882 or MA860H(Havent decided yet.
http://www.leadshine.com/productdeta...AM&model=AM882
http://www.leadshine.com/productdeta...M&model=MA860H
Stepper motors.
KL34H280-45-4A or 34HS38-3008S(Havent decided yet, and yes).

http://www.omc-stepperonline.com/nem...008s-p-32.html
.
Motion COntroller and PSU will still be CSMIO/IP-S and KL-7220.
.
I do beleive this should summarize a good setup, unless there is something i don`t see(again)
.
And again, thanx for advice and comments gents
