Current favourite stepper drivers

[Neale]

My impression is that that they are the cheaper, older, version of the EM806. Basically, same functionality and voltage/current ratings; the firmware is not quite as sophisticated but it's going to need a fairly demanding application to tell the difference. I'm using EM806 very happily, but only on X and Y axes where I'm concerned about things like stall detection - especially on master/slave X axis. I doubt that using AM882s would make much difference, but I previously bought m752 for my first router just before discovering that a) they were about to become obsolete and b) digital drives are much better, and I probably went a bit too far the other way this time. However, I am reusing one of those 752s for my Z axis where the drive requirements are a lot less demanding.

My impression is that if you want a nominal 80V driver to run reliably on 68V, there isn't really that much choice out there. 882/806 - and then what else?
