      Hi, i want to make a cnc pendant for duet 2 wifi, removable, and keep the paneldue always connected, so, is it possible to keep the paneldue on it's own connector and connect the pendant on the Conn_SD ? Or it'll have conflicts (only one will be used at a time) ?

        I'm looking at some of the same things. In my case though, the PanelDue is the more likely to be disconnected, as it's useful on my 3D printer, whereas a pendant probably would not be.

        The PanelDue is basically a serial communication device, connecting to a 4 pin serial port at (by default) 57,600 BPS. There are a few other communication channels open to the Duet, the Conn_SD is one of them. The PanelDue generates gcode commands which it transmits to the Duet over the serial channel. A pendant would probably just have controls at more of a hardware level, so I wouldn't think that they should conflict so much. Of course it depends on how smart you make your pendant to be, and how you want it to interface to the Duet firmware.

          Duet 2 boards have only one free serial port. [Duet 3 boards have two, but currently only the first one can support a PanelDue.] To connect both a pendant and a PanelDue to the same serial port, the TxD line from PanelDue is routed through the pendant, which receives the commands from PanelDue and forwards them to the Duet. The pendant doesn't receive any data from the Duet, so the PanelDue RxD line is connected directly to the Duet.

          This connection scheme means that if you disconnect the PanelDue, the pendant will still work. However, if you disconnect the pendant then in order for PanelDue to work, you will need to bridge the pendant receive and transmit data signals.

            @dc42 hum... It'll be problematic. I'll consider a switch to bridge. Thanks for the answer.

              @krohm-koala - I've never tried it but I can't see why you couldn't use the Pendant we designed at the same time as a Paneldue. https://www.ebay.co.uk/itm/333891754636

              Let me know if you think this will suit your needs. You'll need to be running a windows PC for the software.

                @joesmale we don't want to use your pendant, we've seen it many times, it's nice but expensive for what we want to do, and also, we love open source ^^

                  @krohm-koala - Sorry, I was only trying to help mate. Took us months to develop so personally I see it as a lot cheaper then making one.

                    @joesmale it was not offensive and I thank you for your wanted to help ^^ sorry if you have read it like that, I know that developing a product is expensive and time consuming, I totally understand that you want to make money with it ^^ your pendant is just far out of our budget as it is around 150-160€ for us with shipping ^^

                      @krohm-koala - Thank you for your reply. I was just trying to point out that you should value your own time, even a day developing your own and you are basically valuing your time at very little per hour after material costs. Thats why we made them available for others. Take care.
