I do understand you can vary the scaling of the ppr->movement, the machine im retrofitting never had any scale switch, though never using this machine originally, i dont know exactly how it functioned. It is a good idea though. Thanks!
To PCW: I would use 5v encoders... are the parallel expansion ports capable of high speed encoders? like 1um linear scales?
7i73 looks like a nice option as well.
Thanks!
Better to use the on card 7I95T encoders for machine feedback.
You can put high speed encoders on the expansion ports
but for feedback use its better to use differential signaling
and the 7I95T already has 6 encoder input designed for this.
