As my Shoptask also has ballscrews, I'll be feeding the signals from
the encoders on the servos to BOTH the Geckodrives as well as a
separate DRO. ( A homebrew PIC/LCD per axis )
I admit, what I'll be displaying is leadscrew rotation and not ACTUAL
table movement, but I'm hoping the two will be in very close agreement.
Someday, I'll add separate encoders to genuinely measure actual
movement. In the meantime, this is sort of a "free" DRO and will be a
lot easier than trying to read the dials ( my eyesight becoming
increasingly suspect ).
