But, Mach2 doesn't actually USE the encoder information, except to
display it on the screen. If a motor stalls and it is a whole inch out of
position, it pays no attention, just displays where the machine actually
is, while blindly continuing to ruin the workpiece. What's the purpose
of encoder feedback, if not to keep track of machine position?

Ok. I'm confused here. I understood that Geckos after a 128 pulse/count
dicrepancy between encoder and drive will fault. At 800 counts per revolution
and 2.5 :1 reduction on the drive would only allow about .020" positioning
error before faulting. If I understand this correctly. Incidently, I've used a
Mach2/Gecko setup on a Bridgeport and have not lost a step/ruined a part due to
lost position nor ever lost position in a year and a half under normal
operation. To term it a "Hobby" or not a "Real" control software is a bit
unfair. It reliably does what it is supposed to do. Without the "Real" software
price and they do nothing more than hold position like Mach2. A software that
monitiors axis position via encoder feedback is only required when the axis
actuator is inadequate for the task at hand i.e. insufficient torque etc. Who
wants that anyway?
