Today I wanted to take something apart, and the people that made it clearly disagreed. The screws holding the thing – a doorbell receiver – together were a type of security screw I hadn’t run into before.
In Part 1 I talked about the programming arrangement that I used for the first batch of Z probe boards. After flashing that batch of boards, I got to work on a slightly more automated solution.
One of the more interesting components in the Mark2 3D Printer is the Z probe, an IR probe designed to precisely measure the height of the bed for automatic bed-levelling.
This is the first product that I’ve been shipping that I’ve needed to program and test, and I’ve had some fun along the way trying to make the process faster.
