This is going to be quite an image heavy post describing the rewiring needed to convert between the Leetro controller and the Ruida controller. It is also pretty straight forward on the old Just Add Sharks laser cutters because all of the wires are clearly labelled. The controller was prepared in the previous step in order to make this conversion process as smooth as possible.
The control panel is an easy place to start, both panels have just a single cable that runs down to the controller, both panels are a very similar size, with the Ruida panel being slightly smaller underneath so it will fit in the hole left behind easily. The Pad03 panel clips into place so you'll need to reach up inside the machine to work the clips loose. The cable runs down the inside of the laser and is cable tied onto mounting points inside the metal work.
There tends to be a lot of excess wiring on these machines, a 2m long wire will service 10 different models of laser so the long wires tend to get do…
I've seen people 3D print these surgical mask straps to stop the masks from hanging on your ears and making them sore. My wife says she uses a paper clip but that ultimately starts to ache as well, given that 3D printing is so slow it just makes sense to make a laser cut version. So here is my, laser cut, surgical mask strap, based upon this thingiverse design. Sadly I don't have a mask at home to demonstrate it, like the other things I await feedback from the end users.

A different take on the living hinge, one single continous line allows this to be bent in different ways to the other hinges I've made before.
You'll all be pleased to know that this is the last cut of the panel joinery article, it's been great for me to play catch up with. There will be one more post as a round up but I'm working on something clever for that so I hope you'll appreciate it.
