Re: Pico VS IMService???

of course, is not the limit, it can go to about 300,000 steps/second.

That is impressive

One of the greatest advantages of this is that you can switch back
and forth between CNC and manual operation, and use the computer as a
DRO when in manual.

Another great feature, I assume the computer required encoders and
does not 'see' the steps as the DRO ?

switches, so you can have separate indications of - and + limits for
each axis.

The site

http://pico-systems.com/univstep.html

that shows the board, lists one parallel port. is that all that
connects the PC to the board ? it seems like you have found a way to
exceed the normal 5 inputs of a simple breakout board.
