I have a lot of respect for Mariss and Gecko drives are great, but I
have 3 Reprap printers running micro-stepping
drives and they all have dual steppers on the Z axis run by a single
Pololu bipolar driver. None have ever lost steps.
These are small NEMA 17 motors and a 2 amp driver.
OTOH, when I built my cnc router from scratch, I followed conventional
wisdom and used two drivers for the two NEMA 23 motors on the X axis.
They are slaved together in Mach 3. This also works very well.
