The New Hotness

  • MPCNC: Epoxy-filled Connector

    When I wired up the MPCNC’s tool length probe, I planned to reinforce the wiring with a dab of epoxy. What I didn’t notice in my enthusiasm, alas, was the opening from the rear to the front in each pin slot:

    Epoxied connector - rear
    Epoxied connector – rear

    Which let the epoxy flow completely through the connector:

    Epoxied connector - front
    Epoxied connector – front

    So I cut the mess off and applied heatstink tubing on each wire, just like I should have in the first place.

    Now you know the rest of the story …

    I really dislike pin headers as cable connectors, but that’s what the Protoneer CNC board uses:

    MPCNC - Protoneer Wiring - SSR
    MPCNC – Protoneer Wiring – SSR

    It’ll be Good Enough if I don’t do anything else particularly stupid.
