A return to coherence! (i.e. the laser cutter is back!)

January 24th, 2015 by danbackslide

rejoicingMere moments ago, Jude and I replaced the laser cutter’s high voltage supply. I’m pleased to report that it is up and running again, ready for all your laser-based cutting and engraving needs!

Now that it’s back up and running, I’ve scheduled Laser Cutter Basics classes this coming Friday (1/30). There’s one class at 6PM, and another at 8PM. Both are free! Remember, you need to take a class (either Laser Cutter Basics or one of the more advanced classes) before you can use the laser cutter. Also, our classes are always open to the public — but you do need to be a member to actually use our tools beyond class time. So maybe you should come by on a Wednesday night, take a tour, and maybe join…

The laser loses more blue smoke [UPDATED x2]

dead-parrotSorry to report, but the laser is down for the count once again. This time, the high voltage power supply for the laser tube has rung down the curtain and gone to join the Choir Invisible. I’ll be shipping the remains of the HV supply back to Las Vegas tomorrow morning, and hopefully we’ll have a new one by the end of the week.

I had planned on running laser classes next Friday, but that’s likely too tight a deadline right now. So I’ll be bumping the classes out to Friday, January 23rd.

Keep checking back here for updates!

UPDATE 1/21/2015: A new power supply is on its way to us — Full Spectrum Laser is boxing it up as I type this. I’ll post an expected delivery date as soon as I have the shipping confirmation.

UPDATE 1/22/2015: Expected delivery date is Saturday!

Party time — the laser cutter has returned!

rejoicingLet the dancing begin, for I am happy to report that the laser cutter is back in service! The flow sensor has been replaced with a brand new unit which doesn’t spray water all over the floor. And as a bonus, the e-stop switch has also been fixed, so feel free to push the Big Red Button (though not too hard, for it is new, and we want it to feel welcome).

Everybody say thanks to Jude when you see him — he was the guy who crawled into the laser cutter cabinet to replace the flow sensor.

The laser is down. Please do not panic. [EVEN MORE UPDATED]

UPDATE 11/5/2014: Unfortunately the parts were delayed a bit, but I just got a shipping notification. Delivery is scheduled for Friday 11/7. We’ll get everything installed as soon as we can!

UPDATE 10/3system-down1/2014: Full Spectrum Laser has just received a shipment of flow sensors. They will be testing them this afternoon, then they will send out the parts either later today or (more likely) Monday. Shipping is via two-day air, so I’m expecting to get them sometime on Wednesday 11/5.The calendar will be updated to block out the time until then. Thanks for being patient, folks!

Original post:

Sadly, it is my duty to report that the laser cutter is down until further notice. The coolant flow sensor is leaking from its body. We will be contacting the manufacturer on Monday morning to get a new flow sensor (good thing we paid for the extended warranty). This post will be updated as soon as we have an ETA on the repair parts.

Science! Is Afoot

July 16th, 2014 by danbackslide

A while back I was contacted by Bede Willenbring, a research chemist at H.B. Fuller. He was getting some new equipment for their lab, and wondered if we were interested in getting a scanning electron microscope.

A Scanning. Electron. Microscope!
Obviously the correct answer in this situation is “Yes sir, please, sir!” Arrangements were made, and just a few hours ago we rolled a Cambridge Stereoscan 260 into its new home.


As I write this, McSteve is working on getting it hooked up to the 20-amp circuit in the classroom. We’re hoping that by later this evening we can get Cammie (for that is her name) powered up. After that? No idea, really. If you know how a SEM works, why not swing by? (Mr Willenbring has offered to give us a hand with it once we have power, but more brains are always better!)

I want to extend a huge thank you to Mr Willenbring and H.B. Fuller for making this possible. For great science!
