Low Pressure Air Reservoir for improved cutting.

Image
Being a Hackaday fan and a laser cutter fan, I've been recommended this article about improved laser cutting many times over already. The idea is simple enough, laminar flow from the cutting nozzle appears to improve cutting performance. They don't provide a 3D model and I'm super busy so I employed my newly retired Dad to create one for me. It's a work in progress and I haven't printed it yet, we did find something very interesting along the way though. My laser cutter has a typically large aquarium pump, it's a bit of a 'puffer' and you can hear the air rushing out of the end of it in puffs, not ideal for laminar flow. Dad suggested a low pressure air reservoir to smooth some of the airflow before it goes into the laser. This really doesn't have to be very complicated and a 2L plastic bottle makes a perfect candidate. I drilled a hole through the cap and the bottom (the two thickest parts of plastic) and wedged the silicon tube into the gaps. The

Wine Bottle Gift Boxes

Image
I had a local craft fair this weekend, I wanted to add a few extra/new items to my range so that my stall would be very different from last time. I've seen lots of variations on this wine box so I thought I would make my own version. The living hinges at the top allow the sides to be pulled close and the lid closed, it also a great place to put a handle. The fretwork patterns down the sides make them unique to me as well as the custom labels attached to the side. ( svg here ) I didn't sell very many and I'm not sure any were going to be used as wine bottle boxes, one lady wanted to put plants in it and another was going to put fairy lights in hers. Neither wanted the the custom labels so I'm pleased they were only held on with blue tak. It's definitely given me food for thought with the next craft faire looming.

Wiring the Ruida Controller

Image
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
