History and Ownership

The laser cutter was purchased with donations from diyode members (Mark, Simon, Jamie, Tony and Dave S.), and technically is not the property of Diyode.


 The only extinguisher that should be used is a special CO2 extinguisher. Any other type of extinuisher will destroy most of the laser cutter's components.

 It is recommended that operators wear safety glasses.

Hi, the dropbox link to the laser cutter manual is broken (or disallowed) FYI.

I tried to use the laser cutter today and it is not cutting, alas. Using a cut power of 100, and various speeds of 4 8 12 16 and 20 to test, my results were a cut of no more than .1mm deep each time. The width of the kerf became larger with each slower speed, but the cut\'s depth did not increase. *pout*

I was just informed by Shawn Johnson that he inadvertently (by mistake) pressed the Z-Datum button on the laser cutter, and some adjustment is required before use. (ok fine, Shawn wrote this after Brennan logged into his account, and he\'s watching me now , so this isn\'t a covert hacking operation)

Bed is levelled. Occasional problems reported with x-axis jumping inches. Watch your work careful and report any issues.
