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.
