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!  :)

Well, we'll probably need to keep the Wheezy packages for a while even after Jessie is released, but I feel your pain!  :)

Machinekit already runs on x86 machines, the BeagleBone, and the Raspberry Pi.  Now GP Orcullo reports he has Machinekit running on the Odroid C1 using rt-preempt.  There are no hardware drivers yet, but it shouldn't take lon...

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.

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 ...

After having jamming issues with my e3d v5 with Bowden and 1.75mm I drilled out m6 stud and buried PTFE tube like is done on this extruder. It has worked very well and is reliable as long as PTFE is all the way down and bottomed out. Good move e3d!

Many thanks to +John Olafson and +seemecnc for hosting the 2015 MRRF!  Just like last year, it was a great time, and I met a TON of really cool people.  Some of them I knew from on-line or last year, and some I hadn't met before, but it was incredible meeting everyone ITRW!  I look forward to seeing rural Indiana again next year!

A new video from the +Pocket NC folks showing off their 5-axis mill controlled by Machinekit and a BeagleBone Black from +BeagleBoard.org.  The Autodesk CAD/CAM software looks pretty sweet as well! https://youtu.be/ijqmLLjHbyk
