Open Sourcing the Pegasus

[doobie]

I printed a hollow pyramid again today (http://www.thingiverse.com/thing:8757). It came out nice, except I goofed up and bumped the lid and missed part of one layer and a full layer or two on the supports. I will need to work on better support for when the lid is open. For now I just put a magnet on the sensor. I've always had alignment issues, but due to the loss of the layers it came out tilted a bit, but still looked good: https://twitter.com/CrazyNHMtnMan/st...09893854105601.

I was hoping to print this http://www.thingiverse.com/thing:704409 tonight, but family took over. Hopefully I can kick it off early in the morning. If it prints well I'm going code up a quick z-axis alignment feature and then releaes the changes with documentation on how to enable a system with the firmware.

Also note, that the company behind BeagleBone's released a WIRELESS version that is compatible. I've been using it for testing since Friday night. It seems to work well, but I think the kernel I setup is a little unstable, so I might either upgrade or downgrade. I have the software working in the 3.8 *and* in 4.4.x kernels. I would recommend the 4.4.x kernels, as the software does suck for 3.8..... BTW, the pyramid took about 40 minutes to print. I used a large amount of support structure than I previously used which I hope is why it took so long, but also I increased the time between laser points so it's a bit slower. I was noticing the laser "dragging" from point A to point B if A and B were far apart. I coded but haven't debugged something that will try to alleviate that by giving long moves more time before running the laser, but it hasn't run successfully yet.

Funny story...due to the long move delays I accidentally goofed up and coded something that made the laser/galvo do random things, it freaked me out when I ran it, because the laser started running super fast and moved randomly around and crashed my system. When I rebooted the first thing was I manually disabled the galvo/laser to debug, then family called and 3 hours later when I went back to debug it forgot I disabled it and freaked out thinking I killed the printer. Thankfully it's pretty resilient....

I printed the ball and socket item... I also created a dropbox here for images of prints

Gcode I used for the above (and any other calibration prints) will be posted here:

I do need to post my slic3r files I'm using, probably today or tomorrow I'll post them.
