      @dc42 Just an update, I have beta 5 installed and am in to my 3rd three day print and there is no sign of any missed steps or shifting of any kind, my prints are holding a tight tolerance and I am very happy with the results... how long before I can buy another set of boards?

        @supertb1 thanks for the feedback! We will have information about the production run once the shcedule is confirmed.

          I would like to give a quick thank you to everyone involved with the development of the 1HCL-Boards and the closed loop plugin.

          Running my printer in closed loop is a real quantum leap for me. I can now comfortably print at speeds and accelerations that were really pushing the limits in open loop. In addition, the new level of reliability enables me to run larger print jobs for longer unsupervised periods. My printer was already very tough and reliable, but adding closed loop control fixed the last weak link in the chain. 🙂

          I am eagerly awaiting further developments and improvements. For example, having linear encoders that measure the head's position on the axis independent of belts and pulleys would be the ultimate closed loop solution. But I am digressing.

          Good job everyone!

          Cheers Max

            Hey
            While you're printing with this pieces of gold, I ask myself where I can buy this board or how I can also test it?

            I'm producing custom extra large toolchanger, so it would be that helpful!!
            Cheers

              @maxgyver what kinematics does your machine use? We've experienced some issues converting one of our CoreXY machines to use the 1HCL board and motors+encoders; and we don't know whether it is as issues with this particular machine+motors+encoders or a more general problem with closed loop control of coupled motors.

                I have cartesian printers.
                4 y motors
                2 y motors
                1x motor

                X and Y working with a closed loop system would be nice.

                Cheers

                    So far, I had no mayor issues converting to closed loop.

                      A curious european company wanna try 1HCL.

                      Please provide us some information for further planning.
                      We need the 1HCL but we can´t wait another half a year with testing etc.

                          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

                            @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.

                                            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". !!!!
