Es wurde Zeit, dem Drehdings ein neues Kleid zu spendieren… Die weißen Platten sind sogenannte HPL-Platten (Resopal), diese sind auf einem Gerüst aus Aluschienen montiert.

This is cutting 1/8″ plastic – everything seems to work just fine – 3 passes and the pieces just drop right out. The cutting residue washes off with soap and water.
UPDATE : I was looking for tips on identifying laser safe plastics and found the following video:
Polymer Identification by Burnination from Zach 'Iowa' Hoeken on Vimeo.
…and this technique can also be used to identify if you’ve been taken over by “The Thing”.

My daughter LOVES the Hex Girls, and for Halloween she wanted to be the lead singer. So I decided to build her a guitar closely modeled on the one used by Thorn (or Sally McKnight).
We started with the Batman logo from the 1960′s and did some vector manipulation. Then got a single plank of poplar from the local hardware store. Cut a single strip to make the neck, and glued up the rest to make the body.
I think it was a hit…
Wow, been a long time since I posted about anything. I thought it was about time I wrote about something new. I recently acquired all the parts for a laser cutter – although I was running an 80W tube from the BlackToe gantry I found that the two machining techniques were at odds with each […]
Wow, been a long time since I posted about anything. I thought it was about time I wrote about something new.
I recently acquired all the parts for a laser cutter – although I was running an 80W tube from the BlackToe gantry I found that the two machining techniques were at odds with each other, and the laser needed an environment all of its own. Luckily I had enough stuff left over from my first CNC gantry – the Bluumax – to build a new X/Y table.
Patrick (www.buildyourcnc.com) and I have been talking about laser cutters for a while now – we both thought that putting the tube into the gantry itself was a sensible thing to do, since you would only need to align one axis.
Quite proud of these adjustable motor mounts – came to me in a flash of inspiration:
Here are some movies showing progress, alignment, and “first light”:
…and the finished engraving – about 1mm deep, lowest laser power, 1/4 baltic birch. The flashes of light seem to be where the toolpaths cross. Not entirely sure why this happens. Anyone know?
Update – check out this neat test for laser “tramming” – making sure it’s truly perpendicular – http://www.machsupport.com/forum/index.php/topic,23037.msg162437.html#msg162437
