Which stepper driver is a good alternative to Gecho 540

This would be classed as a Semi-Business machine build. I'm not concerned about the rapids speed or volume this machine can do but its consistent accuracy.

The use of the machine is to carve 3D protype models in milling composite, wood and foamboard. It'll actually be an XYZ with a AB head on a deep Z axis. It also needs to carve positive and negative forms as molds. I'm expecting to be able to switch the AB head out to put in a regular 2.2kw spindle for milling some smaller aluminium parts.

Why skimp on stepper drivers? Good ones cost £100 each, never look back.

Purchased a set of 2DM556 so going down the digital route :)
