Chip off the old ‘bot

Okay, I’m liking the MakerBot and it’s RepRap child.  But, check out that work area!

(I have the same 3-in-1 oil for my MakerBot.  :)  )

Got my groove back

It just wasn’t the same without my old theme.

Of the several WordPress websites I have, this was the first one I moved to WordPress 3.0 when it came out.  Unfortunately, 3.0 totally broke the hell out of my theme.  I suspect it happened when the database was upgraded and it nuked the theme options.  But, an upgrade to the theme1 and a little CSS spit and polish…  and I’m back!

Edit: One unfortunate side effect of upgrading the theme was that it nuked my logo image.  I found the original on Flickr, resized it, and dropped it back in.  However, as you can tell from the nasty pixelation – I used “Paint” to resize.  Blech.  I’m going to have to redo that.

Documenting Skeinforge settings

Uncool tower, cool tower

Uncool tower, cool tower

BotHacker recently documented his adventures in cooling fans and Skeinforge options – to amazing effect. 1  You should read the entire post, because there’s a lot of good info in there.  However, to summarize:

  1. Numerous permutations of cooling fan sizes and speeds offered some improvement.
  2. Using no cooling fans and putting the Skeinforge Cool setting at a minimum layer time of 10 seconds offered a dramatic improvement.

BotHacker’s post is what Skeinforge documentation should look like.

Update: Per BotHacker’s comment below, “Skeinforge must be told to ‘Slow Down’ for this to work. The other option is ‘Orbit’, and may lead to poorer results.”

MakerBot Maintenance

In terms of maintenance, there’s not much a MakerBot needs to stay happy:

  1. Check/floss the extruder (may need to disassemble)
  2. Check/oil 2X, 2Y, and 4Z axis rods
  3. Check/tighten nuts/bolts
  4. Check/replace build platform
  5. Check/tighten belts

What did I miss?  How often do you do these things?

Sketchup STL Importer Plugins

As I’ve mentioned before, I do all of my 3D modeling in Sketchup.  It’s not open source, but it is free.1

Well, I’ve been monitoring the Capolight Electronics Blog lately – and it’s a good thing too.  Besides having some seriously amazing information about the thermal properties of plastic, he’s just posted about some useful importing/exporting plugins for Sketchup.  As easy as Sketchup is to use, it’s just not very good at exporting to STL.  I haven’t tried these plugins out – but I’m hopeful they will do the job.

If you try them out, please let me know how it goes!
