6 Way Microfit connector



  • For anyone fitting something that uses the 3 additional mounting hole on the upper surface be aware that one of them may foul the latch arm for the 6 way connector.

    Tony/David it would resolve the issue if that connector could be rotated 180 degrees so the latch is on the outside of the board.

    This is particularly an issue if a RDD Extruder is to be mounted on the effector.

    Thanks for the heads up.

    just looking at it here, if we rotate that connector by 180 degrees i think it would foul more as the plug overhangs the socket by approx 0.5mm.



  • But that 0.5mm is better than the 1.5 or so the the clip takes up looking at the connector in the kit it looks pretty symmetrical apart from the retainer



  • I know it fouls badly as my 6way block on the effector now is missing the clip to hold the connector in, this is how we found the issue

    If you are careful you might be able to (gently!) pry the 6 way molex plastic adaptor off the 6 pins and put it back on the other way round. Before you do that, if you look at how the plug fits on to the pins, then out it on the other way around (just on the tips,) to see if it is better or worse.

    Good Tip.

    That works not easy to get off but definitely enough clearance now need to re wire the printer now for the reversed connections

  • Mine is already broken so would need a new housing to try it ??


  • administrators

    yeah, the downside is needing to re-wire. Is that part of the nimble mount essential or could a mount with more clearance there be designed?



  • There just isn't enough clearance between the mounting hole and the connector to be honest the pillar on the Nimble mount is 6mm centred on the 2.9 mm hole.



  • you would have to remove nearly all the material on the side and also reduce the diameter of the screw head for the clip to pass it, it is easier (and safer IMHO) to turn the connector round


  • administrators

    Thanks for the feedback.



  • Your Welcome Tony it wasn't a big issue on the beta with the collar mount as that could be rotated was still tight to get at the clip to release it but it was possible this one you can't get it on without removing the retaining clip.



  • I haven't started wiring mine yet so rotate the connector before wiring seems to be the consensus?

    Edit - done, not too bad actually used a plumber's wrench (not necessarily a recommendation).



  • Lykle has now redesigned the adaptor so it should be ok now



  • I have modified the adapter and created a new version.
    I have modified the pillar closest to the 6 way plug to avoid the latch all together.
    The bolt now sits under the latch.
    Here is a link.

    Will you release the STL on its own ?

    I'll ask him to publish it on Thingiverse? are you on the Discord App it is the easiest way to contact the zesty guys>

  • OK for some reason I thought you were in Scotland you live and learn

    Doug

    ps just checked the maps way out east then last time I was on that part of the Island was just before the Turks invaded?



  • OK, added the file to the Thingiverse page as well.
    Only added the STL version, called V2.2 https://www.thingiverse.com/thing:2453322

    Sorry that I didn't release it in Thingiverse straight away. Will be tricky to print, lot of support needed.



  • Any recommendations for printing in regards to supports ?
    Shipping to canada costs more than the parts….



  • I was thinking that given the large nut under the adaptor is hard to access with the adaptor in place, for example to tighten the hotend if it gets loose, maybe the adaptor could incorporate a nut trap to fit the M12? nut provided by Duet. This way the nut would be captive, the heatsink could be screwed tightly into it easily, and then the hotend position set by tightening the heatbreak into the nozzle at the desired position.
