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...

Laser cutter speed difference

-

Here is the video of my two laser cutters cutting the same tile side by side. It prompted a few people to ask 'how come the 30W tube is much faster than the 100W tube?' I picked the new laser cutter  based upon speed. It had a few specification stats that suggested it was fast and the photos showed a fairly lightweight head etc. Now that I have the laser in my possession I can see all the design decisions that make it fast. In the case of these Carcassonne tiles  I only need the full power of the laser when I'm cutting the tiles out. The low power engraving lines are done with minimal power, only 8% of the 30W tube. The metal RF tube gives me much more control over the low end power, the head can fly around at 100mm/s, twice the speed of the larger machine. The engraving can be done at 1000mm/s, again nearly twice the speed and empirical evidence suggests that it is actually moving at that speed. The 30W laser can easily handle the 3mm poplar ply wood at a sensible 3...

Knuff stuff

Here is a new and updated version of this project now available with files that actually work I wanted some magazine racks to tidy up some stuff in the garage. I like the Ikea Knuff  but Ikea is an hours drive away (in one of 3 different directions, it's like the epicentre of non ikeaness here). The other trouble with the Ikea Knuffs is that the two files are slightly different sizes which is not good for my OCD. Anyway, I have a laser in the garage and every problem looks like it can be solved with a laser so I drew up my own Knuff equivalent and cut a few of those instead. Sure they cost me £6 for a pair due to material costs and that ignores cutting times and drawing costs but I now have Knuff in my possession and by the end of the day. Knuff said.
