    Continuing quest to make GARCAD the best-


    6/01/2018  A new bowden tube with 1/8" ID and 3/16" OD reduces drag on the carriage (it is thinner walled = more flexible).  The smaller ID leaves much less wiggle room for storing compression than in a larger tube-  this reduces oozing and make retraction much more meaningful.

    6/01/2018   A new vacuum/air device is ready.  the vacuum is for removing the smoke of lasering while the air serves the jet.ring.
    The vacuum nozzle and mount for the laser is on the way.

    6/01/2018   New hotends have a thick layer of fiberglass instead of the porcelain shell. A thick glaze over that produces a hard insulating foam.  


    6/04/2018   A clip.on electronic noise filter protects the thermocouple data lines from interference.

    6/14/2018   An intercooler now provides additional cooling for long runs of high temperature printing.  It also provides strain relief for the hoses.
                     

    6/20/2018    A 'spice rack' upgrade hangs on the side of the GARCAD enclosure to hold the spoolie box.
                       This reduces the bowden tube length by about a foot.
                       It is also possible to hang one on the other side for dual filament systems.

    7/26/2018    Heated platform gets insulated.  


    A filament switcher that will allow you to change filament via G-code is in the CAD phase...

    A roll feeder for lasering rolled material?

    Filament MT detector for the spoolie?

    Digital hygrometer display on the spoolie?


    The search for a source of black PEEK continues.

    LASER MACHINE is being prototyped.  This is optimized for speed and especially designed for photo image lasering.
     Axes X and Y are driven by stainless steel screws and have the resolution to best exploit the laser dot size (@ 0.0025" effective diameter, although it's really rectangular).
     A raster grid that lands on full.steps or half.steps and is a multiple of the laser dot size eliminates any possibility of certain artifacts.
    Bidirectional rastering saves much time.
    The laser is controlled by gcode as axis Z.
    Axis A is available for rotary axis.
