Vernier Caliper

-

I laser cut some vernier calipers from 3 layers of 1.5mm birch ply, it's fully functional and nearly as accurate as my actual calipers. (svg here)

Tweaks and Changes

The laser upgrade went remarkably smoothly and the laser cutter was functional but there were a few minor changes and improvements that needed to be done. Fixing the screen image Image flipped on the controller The first and most noticeable tweak for my new Ruida system was to fix the screen display. Most of my cuts are symmetrical so it was a day or two before I noticed that the image on the screen was mirrored. The laser cutter was cutting the correct way so I knew this had to be a simple setting on the controller. In the menu system is an option called 'Screen Origin' we have to set this to 'Top Right' so that the controller knows it's cutting from the same corner as the laser. Screen origin setting Screen Origin should be set to top right Image corrected on the controller Wiring in the water protection The additional wire patched into the WP line on the PSU The lid switch and the water flow detection were already wired direct...

Wiring the Ruida Controller

The RDC6442G controller from Ruida 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 Leetro (Pad03) panel on the left and the Ruida panel on the right The view from inside the laser looking up at the control panel 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 mounti...

Leetro to Ruida Settings

The first step towards upgrading a leetro based machine is to acquire a replacement controller. I opted for the Ruida 6442G  to make it the same as my other machine. I bought my controller through ali express from Cloudray , it's currently $266 USD for delivery to the UK it took 3 weeks to arrive and cost around £250 GBP once customs and duty had been paid on it. I would probably recommend buying it through cloudray ebay instead, it's £260 but it'll arrive within a few days. Cloudray  is my current part supplier, they've been pretty good so far. A delay suited me nicely with the Christmas rush on fractal puzzles and other products. The kit of parts as it arrived was very complete. The controller and the screen were protected with bubble wrap and anti-static bags. Other parts include two USB cables to go from the controller to the edge of the laser, one for USB sticks, one for the laptop connection. An Ethernet extension to go the the edge of the laser and al...
