Hi Ray, I am a reporter in Seattle at KIRO Radio working on a story about daylight saving time. I see you were behind a social media push to defeat efforts to change in Arizona, and I wonder if you would be available for a quick interview to discuss today via phone or Skype? Thanks! Josh Kerns

Nice calipers! I scored a harbor freight version and had to “mod” it to accept a AAA battery and external battery holder. Got tired of locating those CR batteries…

Great stuff Ray! It looks like you have a good handle on making things from your computer. I visited the Lulzbot web site and saw that it can use nylon. Have you tried this material? For my application, this would be a strong solution. I still need to investigate FreeCad. Good job, and you’re having fun too.

In reply to schlem.

Hey Todd,

So far (keep in mind I’ve only had my TAZ 4 for two weeks!) I’ve been using PLA. But I too was having issues mostly with layer-one sticking. What I’ve found is that all the recommended temps are too low… they recommend 185 C for the hot end and 60 C for the bed, and I’ve cranked up the hot end to 200 C and the bed to 70 C.

My printer is in a small bedroom-turned-craft room, and there’s an AC vent that blows cold air. (It blows a lot of cold air… it’s 101 degrees outside before 9am today. Welcome to south-central Arizona!)

I did go to Lulzbot.com/support and write in about my layer-one adhesion problems, and got a reply by pretty quick – followed by a few Email exchanges, with some good ideas. I’m surprised, actually, at how responsive the Aleph Objects guys are for an “open source” product. They didn’t ask, “did you buy this from us?” (I did, through Amazon).

Let me know how it goes… and thanks for checking out my new 3D-blog site!

Ray

Hey! I recently upgraded to a Taz4 and I am plagued by ABS warping issues on the PET film. It’s in an unheated space. I have built a quick and dirty enclosure, but it’s huge and hard to keep warm, and probably has its own weather. I do have a 100W bulb in there for warmth.

Any thoughts most welcome! I love everything about the Taz, but for prints over a few cm high, my printrbot kills it.
Thanks
Todd
