Is there a spare stepper motor in the hacker space for testing my new extruder assembly? 
Also can any one suggest a best place (cost effective) to buy NEMA motor and 608 bearings in Melbourne. 
Thx

    It seems to be easier, because there is less contraction on cooling. This
    contraction often leads my prints to tear themselves apart. I have now
    started to print PLA, but haven't got it reliable yet. (Also, I need a
    better way to unroll it.)
     
    However, I think (others should correct me if I'm wrong) that PLA is
    actually stronger, but more brittle. I have had problems with my
    micro-extruder, I have now printed a uniX (similar to Greg/Wade) to use a
    more traditional one. I printed the gears on that one in PLA because I
    think ABS would be too soft. I printed the rest in ABS because it can
    withstand higher temperatures.
     
    I'll let you know how it pans out. At the moment I need a M3 grub screw
    for the small gear.
     
    Cheers,
    Holger

    So while we are on the subject, do we know if anyone makes ABS filament
    that is either grey, and or has metallic particles in it, eg it can kinda
    looks sparkly? Am I asking for too much? :-)

    Thanks a lot Garry.
     
    Took a while to go through the info.I have just attempted to cost the parts
    from BOM that was available in buildlog. Not sure how much can we source
    locally or make it to keep the cost to minimum. Will discuss with you when
    I see you next Monday.
     
    In the attached file there are couple of things that I couldn';t understand
    (marked in yellow). Could you please clarify what those parts are.
     
    Thanks & Regards,
    Dinesh

    Hi Garry, Thank you very much for the clarifications. I will update the BOM.
    Could you also let me know where did you source fully assembled ramps+arduino board - was it reprap discount on eBa?
    Thanks
     
     

     

    Garry Stone <gazo...@gmail.com> Nov 14 04:48AM -0800  

    Yeah reprapdiscount on ebay

    FYI:
     
    Last Night (Tuesday 13th) I took out the CNC Mill and successfully sent it
    a job that was made in Inkscape, I used Printrun (AKA Pronterface) to feed
    the code to the mill and it behaved very well. I found a few tweaks RE:
    Cleaning GCode which I will look at automating.

    Come on down and guess when the tim tams are hidden...
