      Thanks I will try it out.

      Hi guys, I've tried with a stepper motor in a galvo set-up.
      I think that could easily work with the right leverage and it would require less hardware complexity and I would be able to control the speed.
      As I see it, the biggest problem is setting up the axis geometry.
      Has anyone done something similar or do I need to set up a new kinematic?

      Thank you very much for so many constructive inputs.

      I also decided to set the galvo system up as with the scanning principle, but it will cost a lot of unnecessary movements, but it is probably the easiest.

      Could you not make a giude in the duet 3D documentacion, I think it has many people's interests.

      Thanks for your reply.

      It is + - 5v to control the galvo and I would like a resolution of 0.1mm and that corresponds to 0.005V.

      Hi guys and sorry for my google translate english.

      I am working on a SLS 3D printer and am about to connect the galvo motor to a duet 3 6hc.

      My plan is to connect them with a DAC converter to the PWM I/O pin to get an analog output.

      As I understand it, you change the position of the galvo motors by changing the voltage that come from the duet board's PWM frequency.

      My question is that normally the frequency determines the speed of the motor and not the position but here it determines the position so does the reprap firmware allow that and can I control the speed?

      I haven't tested anything yet as I don't have a DAC converter.

      i appreciate all ideas.
