Duet wifi and anycubic i3 mega



  • I am currently having lots of issues with my anycubic i3 mega trigorilla board. I am looking at replacing it with a duet wifi board. I am guessing I am going to have to mount the board out side the case rather than upside down in it with the power supply. I think I saw something saying either the motor or end stop connectors on the duet are nonstandard, so I may need to swap those out. Is there anything else I should be aware of?

    I am probably going to add a bltouch sensor at the same time, which seems like it should not be a big deal. Are there any other upgrades people recommend while I am at it?



  • @mtthws Endstops are different, the 3.3vdc is the center pin of the three. If that board is a RAMPS variant see: https://duet3d.dozuki.com/Wiki/Wiring_and_hardware_differences_from_RAMPS_etc



  • @stephen6309 thanks

    That's right, the major different is the pinout of the 3-pin endstop connectors. With RAMPS and most other boards, the most common type of endstop (a microswitch) uses the centre pin and one of the outside pins, which guarantees that many users plug the connector in the wrong way round and short out the 5V regulator. The designers of the original Duet changed the pinout so that reversing the connector does no harm.

    The motor connections are the same: one phase connected to the two pins at one end of the connector, and the other phase connected to the two pins at the other end.



  • @dc42 sorry I missed your reply. Thanks.

    Out of curiosity could I just skip redoing the stop sensors and just do sensorless homing? Not sure if you need end stop sensors at all if you enable that, and I believe this board supports that.

    Yes you could do that, but you would need to spend time finding suitable motor current and stall sensitivity settings. See the wiki page on stall detection.
