Friday Post: Forgetting to set DNS

Posted on by

Hey All,

So for the past month I’ve been racking my brain trying to figure out the issue where PiPlay says Could not check for updates.  I KNEW it was because of my server move but I couldn’t figure it out.  I couldn’t reproduce it on my end.  I really thought that it was because the requests module coudln’t do redirects.  Tonight I was dealing with a PiPlay issue with a cool teacher in Canada who is making games with her students, and we were troubleshooting a bad wifi card.  We got everything working, and then the can’t connect to piplay server message came up, and I was going to admit defeat, but I then saw it was going to WWW.pimame.org.  I had set up www on piplay.org, but I had never setup the WWW redirect on the old domain.  I feel dumb.  One DNS change and a 5 minute propagation and everything is working now.

On a side note, I designed this warp pipe planter in OpenSCAD, and printed it out today.  I drove out to a local nursery and picked up some venus fly traps, and voila!  One Super Mario Bros. “Piranha Plant” in my own home 😀

Friday Post: Even more 3D printing…

Posted on by

Hey All,

This has felt like one of the longest weeks of my life.  Had a couple meetings about Maker Faire Orlando, pushed out some software that 60,000 students will be using in a month. It’s super stressful.  Luckily it’s Friday and I can end up sleeping until Sunday 😀

I was hoping to have some cool stuff to show this week about the 3D printing software, but of course at the last minute stuff wasn’t working.

My 3D printer is a Micro3D 3D printer.  It’s a small $300 3D printer that is only now just getting people to hack on it.  With 3D Printing, you usually have two steps from model to plastic.

The first step is to run your model (an .STL file) through a slicer.  There are many slicers out there, Cura, Simple3D, Slic3r, etc.  These literally slice your model into layers which are written out as Gcode.

Gcode is an industry standard for 3D Printing and CNC milling that can control extruders, X Y and Z axis motors, temperature controls, etc.  Everything your print will do is going to be from a line of gcode commands.

The printing portion is actually a program that reads the gcode and sends it to the printer to act out.

OctoPi

There is a really cool open source suite of tools called OctoPrint, that combines a gcode processor and a beautiful web frontend to manage your 3D Printer.  A Raspberry Pi distribution was made call OctoPi which allows you to control most 3D printers from your Pi!

Because the Micro3D is so new, support is just starting to come out for it and the gcode processors are a little iffy at the moment.  I was able to get OctoPi to talk to my printer and manually move the axis, but it could not process the gcode properly.  Bummer 🙁

I am sure this will be fixed in the coming weeks though.  I am really happy with this printer.

Be on the lookout for a new PiPlay image.  It’s been too long!

Friday Post: More 3D Printing

Posted on by

Hey All,

Happy Friday!  Brain fried from a week of getting some new software at work prepped and ready to be moved to production.  Scary doing a push because some 60,000 faculty and students might run into an issue.  We test as well as we can, but theres always that one case that you miss.  So nerve wracking.

For the past two weeks my coworkers and I have been printing out tons of things on the Micro 3D Printer. After the first week, everything started to shift horribly to the left on each new layer.  Nothing would print right.  A vocal minority was also having this issue on the forums.  Micro3D has a huge support backlog, so communication was very sparse, BUT they DID keep us in the loop on how they were fixing the issue.  Two new software releases in 2 weeks and it seems to be working fine again.  I am extremely happy with the prints now.

Don’t mind the weirdness with the Eevee, that’s the support structure that pulls off.  I’m mailing it to a friend so I’m leaving it intact.  It’s like 3D printed bubble wrap, I can’t deny her the joy of ripping it off 😀  You can see a couple remnants of the support structure on the pooh bear as well.  I need to clean it up a bit more before I send it to my Mom.  She will love it.

My conclusion: It’s a $300 3D printer,You get what you pay for.  I am extremely happy with it.  It was broken, now it’s fixed to Micro3D’s credit.   I am hoping the shifting issue is now in the past and that it was just a software bug.

Have a good weekend all!
