3D Printer – now better

As I mentioned in the last blog post, I printed a new z-endstop for the printer to replace the one zip-tied in place. The problem with the zip tie stop was the zip tie was on a smooth rod, and it would move if bumped by the carriage.

The first one I printed looked pretty nice; it mounted on one z-axis motor and was designed to hold the microswitch up to contact a printed adjustment piece. The problem with this type was first the mount holes were totally wrong for the style of microswitch I had (too close) and the triangular shape of the holder prevented proper holes from being drilled. The adjuster also would not fit on my x axis motor, so the whole thing was a dud.

I kept looking and finally found a printable small triangular mount that was easy to print, and captures the microswitch perfectly. It takes up almost no room. I had to print this one using a cobbled together solution as I’d removed the zip-tied endstop trying to get the first printed one to work. The printing was not great (the holes were not centered properly) but I was able to drill it and once installed it works perfectly.

Since then I’ve printed a few things, and had a few failures due to my newness at 3d printing, but it’s all good and fun again.
