      Nice, Can I pre order some?

      I need to install the 1HCL with an external encoder because my machines have a double shaft on x axis.
      So I can do a documentation how to place the magnetic encoder install on this board... the documentation says, that for this there will be a description in future.
      Let me know.
      Cheers
      Richard

        @gruna-studio so far the best results we've seen have been using motors with built-in encoders. We're also testing some motors with external encoders, but we've had some difficulties with one of them.

          @dc42 I’d like to order some as well when they become available. Please let us know if we can pre-order.
          Also, could you describe in more detail the issues with closed loop corexy that you mentioned?
          I would be willing to help beta test the corexy functionality if that would help.
          Thanks and look forward to the boards,
          Tristan

            Ok I understand.
            For me it's no option to change the style of the x axis (double shaft nema17) I must work with an external encoder.
            I'm happy to hear that duet will sell this board in the next months.
            Would like to have a few of this little fun maker.
            Please give us a sign when we can order some.
            Thanks a lot

              The first small production run of the EXP1HCL is currently undergoing testing by our assemblers. We should know more on Monday.

                    what is the benefit of 48 volt?

                        really? the motors can drive faster?

                        since two years I´m working with 3d printers and duet and I never heard about it. haha

                        Is there a good summary from Duet?

                        Today is "1HCL-Monday". !!!!

                        cheers richard

                          @gruna-studio driving stepper motors at the desired current depends on having enough driver supply voltage to overcome the back EMF of the motors, which increases with speed. It's especially important with high inductance and high current motors. You can estimate the voltage needed using the calculator at https://www.reprapfirmware.org/emf.html.

                                    @gruna-studio yes! finally over the bottle neck. drop me a line tony@duet3d.com as you have been waiting a while so we may be able to supply directly from next week (before we can get any to our resellers). also @samlogan87

                                    Note support for these is still experimental in RRF 3.4

                                      yeeeeah!
                                      thanks a lot.

                                      So there is the first question.
                                      Is there any experience with specific encoders I could use?

                                      f300a153-a5d4-49da-a5a1-31cdbaf9707d-image.png

                                      Is this an actual information?

                                      If there is no picture yet, I can provide you some good ones and other documentations.

                                      Thanks a lot

                                          @gruna-studio the SPI connected encoders are not yet fully supported. we have done some limited testing but for now I recommend using quadrature encoders.

                                            @gruna-studio the encoders we have had most success with are the 1000 PPR (4000 CPR) ones built-into some 1.8deg stepper motors. There are some examples at https://www.omc-stepperonline.com/closed-loop-stepper-motor/.
