This may be the culprit.  The Water-Break Protection system indeed was the issue.  This wire plugs into the motherboard and the black box on the left is some sort of magnet.  I'm not sure if this is the problem, or the baffle in the water line unit.

It was suggested that I create jumper for the plug involved, but I opted to purchase one at a local electronics store.  I decide to stop by Vetco Electronics on Northup Way in Bellevue.  Bac...

So I've been feverishly working on the new exhaust system (post coming soon!) and set out yesterday to give it a test.  The only problem is that the laser will not fire on command.  Some deduction and testing shows that the CO2 tube is sound, and the power supply seems to be working as well, so that is the good news, two of the most expensive components seem to be functioning properly. But still it will not fired the tube through the controller.

There are...

I was lucky enough to do most of my previous laser work on a Universal system that included a precise and motorized z-axis.  Here is my K40 solution: A Stainless Steel Lab Jack Scissor Stand.  I found it on Amazon for $17.99. It is simply a miniature scissor lift. 

Since the K40 laser I believe comes with a 2" focal point lens, you need to adjust the depth for varying thicknesses. So for example. A 1" thick piece will need to be 1/2" deeper in th...

By far the best show this December in Seattle is the International Wood Block Print Invitational at Davidson Galleries. This exhibition features over forty both contemporary and historical wood engravers from around the world. The work is outstanding! I really enjoyed myself and plan to make a return trip with the idea of purchasing something.  Many of the works are significantly under $100 matted.  Quite a deal for this quality of work.

Otter was the firs...

The K40 laser is shipped with a wimpy underpowered exhaust system.  It is one of the first upgrades one needs to address if this unit is going to be anywhere near any living space.  Laser cutting does stink!

I went to Rockler Woodworking in Tukwila and browsed their fittings and plumbing for woodworking equipment like jointers and planers.  The K40 ships with a fan housing that accepts a 4" diameter hose.  After checking other blogs and such I decided to s...

I don't typically get to Patricia Rozvar Gallery too often as they are uptown from Pioneer Square.  I was downtown a week or so ago and they were open as I walked by, so I decided to drop in.  I happened upon their 25th anniversary exhibition.

 The gallery has moved around a bit as it was located  across the street from the Seattle Art Museum at one time.  They are currently at 1111 1st Avenue, more or less right in between Pioneer Square and The Seattle A...

Since I seem to be able to get the K40 to cut and engrave satisfactorily, it is time to start improving it.

The exhaust system for the K40 has some quirks to contend with. Somewhere I read that an owner thought that the K40 unit was designed for engraving primarily rubber stamps due to its small working area.

One of those quirks about the machine is that the exhaust funnel extends about 1/2" into the cutting area effectively reducing the work area the same. This...

I was pleasantly surprised to find these wonderful paintings by Darlene Campbell at the Prographica Gallery in Pioneer Square last night.  I received my MFA along with Darlene from The Claremont Graduate University way back in 1986.

Darlene's work tends to be of somewhat stark Southern California architecture (homes) and landscapes.

 I hadn't seen the gold leaf details incorporated before.

Like her earlier work, he style is meticulously done.  I didn't even...

Success! I found one of my  existing Illustrator files to use as a test subject - what else but a salmon.  The file is first exported from Illustrator as a .dxf format.  Next, I placed it onto a thumbdrive to import it to the "laser" computer, the one I have decided to keep offline.

From there the .dxf file is loaded into Inkscape, an open source vector graphics program to convert it to Laserdrw file. The file(s) is/are next loaded into Laserdraw, the...

 I made it to the Seward Park Clay Studio Holiday Show and Sale on Saturday. As usual a great event.

Quite the variety.

I enjoyed these pieces with the lathe turned lids.

A few more with wooden lids.

 Like a said, plenty of variety.

 The sale runs until the 24th from 10-6, with late nights on the 6th and 14th until 10 PM. A great place to go gift shopping.
