Honeycomb bed holdown pins

the best laser results are achieved with flat (non warping materials) in order to maintain consistent focus. Also, when cutting light materials like paper, the exhaust turbulence can kick up the material and ruin your job or at worst… catch fire. (speaking of which, I hope you all keep a small fire extinguisher in easy reach, near your machine - safety FIRST) I hope you find these useful. I used to 3d print them for my other laser cutter but occasionally , they would see the wrath of the laser …

Passthrough hold-down pin

I have found long materials tend to not be as flat as proofgrade sheets, so I’ve been using hold-down pins but not pushed down all the way so that I can slide the material down during each step. They also act as guides for the edges of the material. I decided, why not make a versions specific for this task, then realized they work just fine as regular hold-downs as well. I present: [image] Passthrough pin.svg.zip (2.4 KB) I use 4, one at each “corner” where the material enters and exits th…

Warp Wedges

As I use quite a bit of cheapo ply, ~0.2" thick mainly from my local Lowes store, and most of it warps as soon as you look at it, I’ve needed a heavy duty hold down that I can laser cut. I’ve tried the hold down pins, but found that they pull out with the strength of this ply, so I’ve designed my own. Step forward the Warp Wedge. Much stronger than it looks, due to being in tension, the lower hook locks onto the lower face of the honey comb, and the cut out wedge slides under the top hook giv…

Boxes.py has hold down pins!

These are L-shaped and could be very useful! https://www.festi.info/boxes.py/LaserHoldfast?language=en I dl’d them and modified them some… [LaserHoldfast] they slide in easily but tighten up if pushed down on
