‘This has never happened before’ yet again ….

Since my last post I’ve gotten this much printed:

Yes, nothing. Nothing except frustration and fails.

3D print fail - Kevin CaronAfter many days and hours of troubleshooting – Steve Graber was here so many hours (15? 20?) over 5 days that I offered him our spare bedroom – he and I narrowed down the problem to a bad motor.

Yes, of the 3 motors that run the Cerberus 3D Gigante, one had decided to no longer count steps, one way only, though.

Our first, oh, dozen or so hours of troubleshooting didn’t even touch the problem, which was causing every print to thin out one one side. At first we thought the bed wasn’t level, but after several attempts at leveling it using 2 different probes, it became clear that wasn’t the problem.

Finally we heard a slight variation in the motor sound when it neared one particular side. We also remembered that the last print I’d done, the large version of my 3D printed sculpture Ruby, had printed oddly at the bottom. It wasn’t so bad that I couldn’t use the print, but I knew I’d have to account for the lopsided bottom when I printed its base. I just couldn’t get that base to print, though.

So the problem had preceded all the work and improvements I’d just spent a lot of money on.

Steve rewired the motors to see if it could be the wiring, proving that it was indeed the motor.

Well, it better be: a new one just cost $300. Steve notified the motor manufacturer, who said, “We’ve never heard of this.” (They have now.)

It’s now been a month since I’ve been able to print, but I think we’ve got it.

Nonetheless, pray for me, and the printer! And stay tuned ….

Mad scientist performs 3D printer brain transplant

mad scientist!Wouldn’t you like to see that headline in your newspaper or favorite news Website? It’d be at the top of mine, because that’s just what happened recently with my 8-foot-tall Cerberus 3D Gigante 3D printer.

The Gigante is 5 years old now, which is like 50 in 3D printing years, especially with the rapid changes in the field. I’ve been suffering through a lot of 3D print fails, and the last large-format 3D print I completed somehow printed at an angle.

Even Cerberus 3D’s Steve Graber, the mad scientist who built the printer, couldn’t figure out how that happened.

Multiple problems with chattering and fails led Steve to recommend replacing the Gigante’s brain.

We last did this 2 years ago, updating to a new Smoothie controller board, which is, in essence, the 3D printer’s brain. This time, though, he prescribed a totally new type of controller board …. Read More →

Let there be light: adding lights to my 3D printers

Cerberus 3D 400 3D printer - Kevin CaronNow that I have my 3D printers pretty well stable – well, for now – I’m having fun refining the machines.

With motorcycles, it’s called farkle, or any modification of your bike. In this case, the changes I made were a little more practical, but yeah, they look pretty cool, too ….

More often than I wish I’m up in the middle of the night, checking on a print. I’m not sure why it works out that way, but I’ll be low on filament or maybe just wake up and figure I’d better take a look.

(If I’m low on filament, I’m not sleeping well anyway – it’s sad to lose a print just because you didn’t plan well.)

I stumble out to the dining room, where my 8-foot-tall Cerberus 3D Gigante 3D printer is is, or the office where the Cerberus 3D 400 3D printer (right) is, and turn on the lights, squinting to focus.

Now, with my latest addition, I have a little help ….

Cerberus 3D 400 3D printer opens a world of filament

When my first 3D printer, a 3D Systems CubeX, apparently died (more on that in a moment), I lost the ability to work in anything but PLA filament.

3D Systems CubeX 3D printer - Kevin Caron

That mattered to me, because I have one design in particular that seems to prefer ABS.

I had tried repeatedly to fix the CubeX, ordering and installing boards, but it became clear that I needed to consider another direction ….

The CubeX is dead; long live the 400

My first 3D printer was a 3D Systems CubeX. I found out about it through the company that makes Alibre, the CAD software I use most often. I figured, “If they recommend this machine, it must work well with Alibre.”

It took several months to get the machine, and I jumped right into using it. Although it could supposedly print in three colors, I never mastered that. I did, though, get a lot of use out of the CubeX, especially using ABS filament ….

Tinker time for all ages: event turns on young and old

3D printing at Arts & Technology event in Surprise, AZ - Kevin CaronWhen you’ve done something for a while, you start to take it for granted.

There’s nothing like talking to others about 3D printing – and, best of all, showing it to them – to remind me how remarkable this technology is for many people.

Recently, my wife spoke with a woman who had never even heard of 3D printing. That’s pretty mind-blowing.

Most of the people who attended the inaugural “Technology & Art: A Tinker Time For All Ages” on Saturday, October 21 had heard of it but never seen a 3D printer in action.

They have now….

Art takes 3D printing seriously at ASU

3D Systems ProJet 660 3D printerOne of the strongest intersections of art and 3D printing is taking place right here in Phoenix at Arizona State University.

I first encountered Dan Collins, who is a professor of Intermedia in the School of Art as ASU and a co-director of the PRISM lab, an interdisciplinary 3D modeling and rapid prototyping facility.

Dan has been involved in 3D printing for a long time. He was involved with TeleSculpture, which was held in 1999, 2000, 2001, 2003, 2005 and 2007, in which artists would simply send in their designs, which would be printed remotely for the show, an incredibly innovative idea, one certainly ahead of its time.

(You can read more about Dan’s activities and involvement by clicking on his name above.)

What Dan and his team have done is amazing ….

How many 3D printers does one person need?!

I admit, in some ways this is embarrassing.

But as I told my wife, really, it all makes sense. “It’s just the way it worked out, honey.”

I am now the owner of three, yes three, 3D printers. Three years ago, I didn’t have any. The more I’ve learned and the more fun I’ve had, I’ve justified owning each one ….
