That new laser tube smell

June 23rd, 2017 by danbackslide

That bright crisp smell you’ll notice in the laser room is the smell of new laser tube. It’s accompanied by undertones of fresh mirrors and beam combiner, with a smooth realignment finish.

Please test your settings the next time you run a job! The replaced optics and tube basically give us a nearly-new laser cutter, so you may be able to lower your power settings and/or speed up your cuts.

Huge thanks to Rory Johnson and Mark Tondra for helping out tonight. Also an extra huge thanks to Rory for doing the laser maintenance over the past months.

Now, anyone want to try taking an old laser tube apart?

Laser update: no upgrade tonight…

June 1st, 2017 by danbackslide

Last week when I got the laser back in operation, I said I was planning on putting the new tube in tonight (Thurs 6/1). Unfortunately, between Mini Maker Faire this weekend and other Real Life duties, that’s not gonna happen. I don’t want to be doing all that work when I’m feeling pressed for time, as that’s when mistakes are made. I’ll post here and in the TCMaker Google group when I’ve got another date set. Don’t worry, it’ll be soon — my wife wants the death ray crate out of the house…

The laser is up! (mostly)

May 24th, 2017 by danbackslide

I am quite pleased to report that the laser cutter is back in action mostly! Turns out it was the power supply, and the new unit has been bodged into place. I’ll put some decent connectors on the wiring next Thursday, but what’s there is good for now (just not long-term durable).

So about that ‘mostly’ part: The magnetic safety switch is acting up. It looks like the magnet on the lid has either moved a bit (unlikely), or has lost some magnetism (still unlikely), or the switch itself is losing sensitivity (more likely). It’s been temporarily fixed by taping a chunk of fridge magnet on top of it, which adds enough oomph to get the switch to activate. Another thing to get fixed next Thursday.

The plan is to put in the new laser tube, mirrors, and beam combiner on Thursday 6/1. If you’d like to help out, or just hang out and kibbitz, come on by. I’ll probably be starting around 7pm.
