Sol Diego Laser @ Colab

Laser cutting/engraving for the Sol Diego community

Classes Scheduled

Posted on January 24, 2017 by Paul Williamson

~~Two~~ Three new sessions of the basic operation and safety training course for the Sol Diego laser cutter/engraver at Colab have been scheduled:

Tuesday, January 31, 6pm to 10pm (update: NOW FULL)

Sunday, February 5, 1pm to 5pm (update: NOW FULL)

Tuesday, February 7, 6pm to 10pm (update: NOW FULL)

If you’d like to sign up for one of these classes, please email class@colaser.org and let me know which session you’d prefer. The laser room is small, so class size is limited.

The class is free, and once you’ve completed the class you’ll be able to schedule time to use the Colaser, which is also free for art and personal projects. You don’t need to bring anything special to class. Be prepared for about 90 minutes of classroom instruction, followed by hands-on exercises with the laser.

Power Inlet Re-Repair

Posted on January 7, 2017 by Paul Williamson

My quick and dirty repair of the power inlet module lasted about five weeks, and then burned up, as seen here:

So this time I ordered and installed a replacement part (Interpower 83110131) and got a new power cord.

Instead of the excessive 20A fuses that came with the laser, I installed a 15A fuse. I plan to measure the actual current draw soon. Full Spectrum now says it should be only 5A surge and 1.5A continuous. However, when the laser was first installed it was popping a 15A circuit breaker, so I don’t believe their numbers. If I can drop down to a 10A fuse, I will, because that IEC connector is only rated for 10A.
