Posted on June 5, 2014 by robertwilkie

Adafruit made a fix for Printrbots so that you could feed them the new NinjaFlex filament.  NinjaFlex (NOTE: I have not used it myself) is a filament that prints flexable designs.  Seems like a rubber.  However printrbots extruders are too … Continue reading →

Need a list of hobby 3D Printers and Prices

Posted on June 4, 2014 by robertwilkie

Pretty extensive list of 3D printers, basic specs, and price.  They also list the availability.  I noticed only printers that have physically made it to folks hands are on the list. http://www.3ders.org/pricecompare/3dprinters/

LinuxCNC Probing

Posted on June 4, 2014 by robertwilkie

I was reading this article during lunch about using HAL in linuxCNC and probing.  Why?  Well its a good way to level the table, or get the height a part is, zeroing out axis’s.  etc etc. http://7xcnc.com/software/probing/

Add a LINBUS (car) Injector with Arduino

Posted on June 4, 2014 by robertwilkie

I’ve heard of CAN bus, but not LIN before.  Apparently its the protocol used to to talk to buttons, lights, and switches the user uses. http://hackaday.com/2014/04/19/a-lin-bus-signal-injector/?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+hackaday%2FLgoM+%28Hack+a+Day%29 sourcecode https://github.com/zapta/linbus/tree/master/injector

Rebuilding my CNC, Part 5 SUCCESS

Posted on June 4, 2014 by robertwilkie

Success! LinuxCNC seems to work just fine, I slowed down my y-axis as I did before so the gantry doesn’t whobble so much.  But I cut the example LinuxCNC in foamboard.  What next?  Time to learn PyCAM

EGYDuino, a one sided arduino

Posted on June 3, 2014 by robertwilkie

Nice build of an arduino board that has only one sided circuit and thru-hole.  Makes it easy to build yourself (edge a card that is) and its sized to take a standard arduino shield. http://www.electronics-lab.com/projects/mcu/033/index.html
