    Custom G-code Generation with Mecode

    If you've ever wanted to hard-code gcode but still retain some scripting flexibility (for art, science, or engineering), Jack Minardi just posted a custom g-code generation package he's been working on... it looks great.

    Checkout the RepRap wiki entryand
    also the github repo with instructions

    This could be a big win for 3d printing sacrificial inks like sugars and pluronics where each extruded filament position needs to be placed with precise (x,y,z) coordinates. And for arcs and meanders, there are built-in functions too! Very exciting. From the Github README:

    To use, simply instantiate the G object and use its methods to trace your desired tool path.

    from mecode import G
    g = G()
    g.move(10, 10) # move 10mm in x and 10mm in y
    g.arc(x=10, y=5, radius=20, direction='CCW') # counterclockwise arc with a radius of 5
    g.meander(5, 10, spacing=1) # trace a rectangle meander with 1mm spacing between passes
    g.abs_move(x=1, y=1) # move the tool head to position (1, 1)
    g.home() # move the tool head to the origin (0, 0)

    We got a chance to meet Jack at MRRF and everyone had a great time. Jack Minardi is currently a Research Fellow at Lewis Lab at Harvard.

    Join us at 2014 Midwest RepRap Festival (MRRF), Goshen, Indiana, USA

    I'm really looking forward to this!!

    http://midwestreprapfest.org

    The 2014 Midwest RepRap Festival in Elkhart County Indiana is the place to be March 14-16th. This event is totally FREE to come and attend, there are no tickets, no entry fees, just come hang out all weekend and hang out with other 3D printer guys and gals, but please fill out the RSVP form by following the link above so we know how many people to expect. This event will feature build-events, guest speakers and more!
    Highlights of the event:

    STATE OF REPRAP Come hear Josef Prusa speak on the state of Reprap.
    TEST AND TUNE Experts will be on hand to help you troubleshoot issues or take your prints to the next level!  The event is FULL of people who want to see everyone become an expert.  Whether it’s a simple question about a software setting, a new mechanical design, recommendations on where to go to get into reprap or more, don’t hesitate to ask anyone at the event.
    MEET THE MAKERS  Meet some of the big names in RepRap, like MaxBots (Mendel MAX dev), Josef Prusa (Prusa Mendel/i3 and more), Logxen (Smoothieboard Dev) and many more
    CRAZY NEW REPRAPS  Nicolas Seward (RepRap WALLY, SIMPSON, LISA) will be showing off his newest reprap creations, and talking about the unique features of his designs
    BUILD EVENTS  More to come soon on Build events ….
    3D PRINTING CHALLENGES  See some of the most difficult prints take shape over the course of the weekend, and some fun printing challenges too, like the hand-fed extruder print challenge
