Will try to share some of the awesome stuff that students make while doing #fabacademy Last week it was #lasercutter week: Mkhitar from #fablab Dilijan (Armenia) came up with this brilliant idea to laser joints in an angle.

Someone at our makerspace is struggling with the laser cutter, and it's a problem I've never run into before, I've never seen anything like it - so I thought I'd ask here and check if anyone has any clues.

They're trying to make boxes using this box generator: https://boxes.hackerspace-bamberg.de The box shapes export as SVGs.

The laser cutter is a HPC LS3060 with 50W CO2 laser, connected to the makerspace laptop with a USB cable.

And the laser cutter software is Lightburn on Windows. The files end in ".lbrn2".

Basically, everything looks perfect in Lightburn, including in preview. But when they go to cut, even when each individual shape is in a different layer, the laser will put extra cuts in or randomly move off at a strange angle and make cuts that aren't in the Lightburn file. (See photos of errors attached.)

Have you ever seen anything like this? If so, did you ever work out the cause?

Edit: FIXED! We emailed the people who sold us the laser cutter, and they suggested we check whether our makerspace member was "streaming" the cutting from the laptop with the controls in Lightburn, or if they were sending the file to the laser cutter first and then directly cutting from the laser cutter UI. The member was "streaming" it from the laptop (pressing "start" in Lightburn on the laptop), which apparently can cause these kinds of problems. When they switched to sending the file to the laser cutter and pressing "start" on the laser cutter buttons, it fixed the problem completely and instantly. :)

Still waiting for snow

A few days ago I tried engraving on card paper. I took some leftovers from a previous project and tested several settings on @xHain_hackspace’s lasercutter. I’m happy with the result of Test 3.
I’m excited about the color change and already want to test this on other colors!
I wonder if engraved white paper will turn slightly brown/cinammon color.
