    @lbi we looked at that but, as you can see, there is not a lot of space left!

    Every board has two sides. ๐Ÿ˜‰

      @zapta true. in this case we need to keep the board manufacturable at a reasonable cost and also thin enough to fit on a hermera tool on a toolchanger ๐Ÿ™‚

        @martin7404 its a 3d-accelerometer, you can adjust the orientation in software.

          @t3p3tony, that's correct, good engineering is about striking the right balance.

          BTW, I appreciate the density of your designs. I presume this one is also with Kicad. I played with much simpler design and know how much effort it takes.

            A small wish (and with please ๐Ÿ™‚ ) :

            In the next iteration, maybe already the next board-run(?), please consider reviewing if you can add in also the through-hole-solderpads for the stepper-motor-out
            (guess I am one of the few that are no "crimp-ist", push-in would be favourite, otherwise will stick to screw-in-terminals ๐Ÿ™‚ )

              Push in is very nice, but expensive compared to crimp connectors, and quite large - I haven't seen any with less than 2.5mm pitch and they tend to be quite high.

                Thanks so much for answering! Yep most I found in some webshops were too expensive/big/... for now, but I just wanna try something other then crimping, maybe I stick with solder-in-screwin-terminals in the end... Guess I am on some sort of a quest there ๐Ÿ™‚ if you provide me the 4 additional motor-throughhole-solderpads, I will see what I get and will post it in the forum ๐Ÿ™‚ I guess my talent for crimping is just not really there ๐Ÿ™‚

                  @lbi do you have a proper crimp tool?

                  I hate crimping, but once done it makes disconnecting and reconnecting wires much quicker than using screw terminals.

                    Are there any parts for crimping bundled with the toolboard (like duetboard)?

                        @fotomas I did received mine from dold
                        And it working great.
                        For now I tested only accelerometer as far I am building new large 3d printer. It took 15 minutes to crimp wiring, solder the 120 ohm bridge and run.

                          At least I am not alone in the universe with that issue ๐Ÿ˜Š ๐Ÿ˜€ yeah of course you have a point, I know I can force myself to do it, just the outcome is appropriate to my feeling while doing it, I can borrow a tool at work, but some of them work even better when "crimped" by hand with a tiny plier... Ah for now I crimp, it is alright. Just would be great in the future to have the possiblity maybe to even order them with no connnectors soldered and buy either a screw-in or a crimp-connector kit and just solder it there, and for that the 4 through-hole-pads for the motor are missing. I know this would be / is for advanced users... but my solder-skills are actually not as bad as my crimp-skills are. Didnยดt want to bother all of you. It is allright. Keep up your work!

                              @diy-o-sphere there is another batch currently undergoing testing, so I don't think it will be long.

                                Nice work, great to see that you listen to customer feedback.

                                Some feedback/questions from my end:

                                • I do like the crimped connectors, but nice to see that the holes are still there for people preferring screw terminals. A suggestion for a future revision would be to align these holes so that one solid row of screw terminals can be mounted instead of separate sets. This makes the terminals a lot more sturdy and one would be less likely to damage pads or connectors if using too much force fastening the wires.

                                • As a v1.0 owner, I'm a tad sad to see I'm missing out on all the accelerator fun.
                                  Therefore the question whether I (being familiar with patching hardware, soldering and epoxy) would somehow be able to retro-fit an accelerometer to the v1.0 hardware. I was thinking about some daughter board holding the accelerometer and some passives and then connecting it to some pads/traces.

                                  • If possible, any docs on what to do, or schematics to look at?
                                  • In either case, it might be a good idea for a future revision to break out every (unused) signal/pin to testpoints so patch boards can be made.

                                  @khenderick we decided not to attempt to add an accelerometer to a v1.0 tool board when prototyping, because it is difficult. First, you need to access pads of the SAMC21 MCU that are under the chip. Second, you need to connect a level shifting IC between the MCU (which runs at 5V) and the accelerometer (which runs at 3.3V).

                                  If you decided to attempt the modification yourself then you would also need to build custom firmware, because some of the pin allocations were changed between version 1.0 and 1.1 in order to free up pins for the accelerometer.

                                    @khenderick Schematics are here, if you choose the hacking option:
                                    v1.0: https://github.com/Duet3D/Duet3-Toolboard-1LC/blob/master/ToolBoard_1LC_v1.0/Duet3_TB_1LC_Schematic_v1.0.pdf
                                    v1.1: https://github.com/Duet3D/Duet3-Toolboard-1LC/blob/master/ToolBoard_1LC_v1.1/Duet3_TB_1LC_Schematic_v1.1.pdf

                                    You don't have to miss out; you can connect the accelerometer to a SAMMY C21 board (and connect that to the Toolboard CAN) or direct to the mainboard.

                                      The v1.1 tool board schematic linked to above isn't quite right, because the board are modified during production:

                                      • the INT output of the accelerometer is no longer connected to PA19 of the microcontroller;
                                      • INT is instead connected through a silicon diode to PA00.
