New build – input/comments appreciated

[hanermo2]

Right, ok, now I get it. I misunderstood.
Spot on.

I have a 10-pack of new 2M542 stepper drives, cost 45€ each. Very good drives, I removed the gecko (251) drives from service. Less noise, no back emf, differential (I used single-ended).

These pair well with the cheap 23 size steppers, and are, as you said, ok for lots of smaller machines.
Well under 100€, as you said.
For small machines with nema 23 motors, that type of stuff is good, and cheap.

Its only once you go to larger steppers and higher voltage/current drivers the cost goes up, and is then about the same as servos.

Hannu I didn't say EM808 I said EM806 and the AM882 which is pretty much the same drive can be bought for £50 add £25 for 3Nm nema 23 and that's well under £100. I fit these all the time to routers and they easily handle what is required for router machine this size.
