      Hi Guys. I am building a super accurate laser cutter. I would like to use steppers with encoders attached to the table (not on the motors). Do you have suggestions on how to do that? I was considering using mitutoyo encoders, connected to the PSU-200 interface, with digital quadrature output.DROsystem_2217-1.pdf
      Thanks

        I am also trying to build a super accurate machine with the Duet.
        At the moment i have yet to achieve my target, but it's hopeful.

        far as I understand it you'll need 1HCL boards for each motor, and if you want to go closed loop then a magnetic encoder board for the motors.

        If you don't go closed loop the only way to get the encoder ticks (at the moment) is to run a M122 B(can address) and parse the result for the encoder tick.

        If you do go closed loop, you'll want to tune the values, and spend quite a bit of time tuning at the speeds/accelerations you plan to run.
