Well who ever wrote that is talking rubbish or more likely they never used an external motion controller. Night and Day difference between them.

If you want cheap but good External controller then Pokeys 57cnc is great little board and uses Ethernet which is much better than USB. To be fair most of the current main stream lower end motion controllers like Pokeys, UC100 or UC300, Pmdx 411 are ok and far better than PP.

Regards the drives then don't be afraid of buying AM882 from China I've bought 100's and not had one faulty or problem.

If you go with Nema 34 larger than 6Nm then go with High voltage mains drives.
