This build log was pretty interesting. It's was nice he provided his configs. It let me check my modified comet.hal before I start converting my parallel port driven mill to machinekit

I was lucky enough to get to do BattleBots 15 years ago.  The "reboot" premiers THIS SUNDAY on ABC, and it looks AWESOME!!!
Their world is fire and blood... or oil, that is. The wildly popular gladiatorial robotics competition, BattleBots, is returning to television, and it's actually happening sooner than some of us realized. Sunday, June 21st, at 9pm EST on ABC, the shrapnel will fly in the BattleBox once more. This time around, audiences will be treated to the wonderful commentary stylings of veteran sports broadcaster Chris Rose. Chris will be joined at the desk b...

"you don't want uncontrolled fighting robots zooming around the arena because their radio links are going crazy!"  ... or DO YOU? Hah. If I were building a battlebot, I'd go straight for frequency jamming, and probably get banned immediately!

Two designs for mounting the BeagleBone/CRAMPS combination I just found out about:  http://www.thingiverse.com/thing:765029 and http://www.thingiverse.com/thing:534266
A hardware mount for the beaglebone black/CRAMPS 3d printer interface. Two part solution including standoffs, strain relief, and active cooling mount for 20 mm fan. Mounting holes for M5 screws onto 2020 extrusions.

I forgot how much noisier the Allegro drivers are vs. the TI DRV8825, but the TI part has the nasty microstepping issue.  I'm going to have to give the TMC2100 a try...from the data sheet they look pretty awesome!

I see. Time to go bolt shopping. They should really include the short bolts on these then.

I had a few hours I wasn't cooking this morning, so I hooked up the CoreXZ (idle since MRRF) and finally got it printing. I don't like printing useless trinkets, so I'm printing parts for the "Improved Printable EggBot". Hopefully the EggBot will be finished and working for NEXT Easter (or maybe by Christmas, it would be fun to print some custom ornmaents)! :)

Sadly, I killed my E3D hot-end.  It kept jamming and by messing with it so much I broke the thermistor wires (replaced with a spare) then broke off the heater wires (no 24V heater spares).  After ordering spares, I was browsing the E3D instructions again, and noticed the note about retraction.  0.5 to 1.0 mm is suggested, but I was working with a Slic3r config based off my Ubis/Maker-Gear hot ends, where I run 3.0 mm retraction.  I think I figured out why I was jamming the E3D so much!  It really does have a very short hot end and melt zone and doesn't need a lot of retract.  <doh!>

Ah well, it gives me an excuse to order the new 'lite' version to play with!  :)

Lots of fun watching with my kids.  They weren't born in time to see the previous version, but fortunately YouTube has filled in a few of the blanks!  :)

Use open source apps and strong end-to-end encryption!

That day when you're getting a lot of work done, up until you realize the mail server filled up it's hard drive, which is why you haven't gotten any email for the last eight hours.  <sigh> <fixed>

I can relate. When things are too quiet I wonder if our beeper system is down.

Happy Birthday Machinekit!
A year ago today, Michael Haberler, Charles Steinkuehler, Kent Reed, Alexander Rössler and I finally haggled out the final wording on the Machinekit project announcement email. As Michael clicked the Send button, we had no idea what to expect. Would anyone join our project, or would we hear only ...
