As I re entry upgraded the z-axis of my x-carve to the CNC4NEWBIE ball-screw/linear guide upgrade I discovered my home made (Glowforge) dust shoe no longer fit in the back where the ball screw comes down. Given how hard it is to get proofgrade thick acrylic, I decided to try and cut the old one on the Glowforge. Now the biggest problem is that it is 2-layer sandwiched 1/4” proofgrade clear. The laser can’t chew through 0.5”, so I had to do it in stages. In hindsight this might have been a better project on the x-carve. But my idea, was cut a layer, crack it off with a screwdriver and cut the next. The registration was not perfect, but that’s not super important.
The first problem I rand into was the brush border got in the way of the laser (ugh), do then I had drippy nylon and a thin spot on my brush. Later I taped it down, like a blue tape hairband.
Picking the focus point was strategic as the model came apart.
Next I ran into the annoying dialog placement when drawing shapes in premium…, sure be nice if you could drag the dialog…
In the end the upgrade was a success, and required more parts that anticipated (new x-axis, now the new wide makerslide), and soon 9mm 3gt3 belts and 269oz-on steppers.
