    PentiumPC got a reaction from Tuetuopay in i2c HD44780 LCD Booster Shield   
    Hi, 
     
    I have made some changes since I posted this but it should work as it is.
     
    I will attach the new code here so you try it.

    PentiumPC got a reaction from pine in Fun weekend project! - Mini Marble machine.   
    A fun project while stucked indoors due the haze situation cause by land burning in Indonesia. The PSI averages at 300+ and is deem hazardous to go outdoor without a mask.
     
    Machine is modded from the original design http://www.thingiverse.com/thing:98669, with whatever I have on hand.
     
    Runs on a regular Hobby Servo (futaba 3003) , modded for continuous rotation,
    Energia and MSP430 Launchpad.
     
    Todo -  add some sensor or trigger to start and stop machine based on an event. e.g. PIR etc.

    PentiumPC got a reaction from GeekDoc in Getting a RigidBot 3D printer, help me learn?   
    Went to the frame maker today, he charged me a bomb for a piece of branded German Borosilcate Glass, the thing about Singapore it is sometimes hard to find parts, most businesses are not interested in dealing with end-users, those that do, charges you a premium, the borosilcate glass cost about $80, the guy throw in a $3 piece of regular soda-lime glass for me. 
     
    Tested printing with the regular glass, non heated, I am very impressed with the results, the piece came out clean and nice, not much stringing issues and definitely no melted base problem.
     
    Calibration was done at 0.1mm layer height, the glass is pretty flat, much better than the aluminium bed that come with the replicator.
    Printed at around 225deg C, non heated glass platform coated with PVA white glue. 0.2mm layer thickness. if I stick to PLA I will happy with this piece of $3 glass.
     

     
    Tested and meddle with hairspray but did work, will mess with active cooling next.

    Thanks for the tips @@PentiumPC ! I particularly appreciate the tips on PLA print speed and keeping the spare nozzle. The point that PLA (like ice) doesn't really have a "plastic temperature", but rather goes from solid to liquid is also quite interesting. It would seem to me that the cooling fan/duct I see at the nozzle of many extruders would be of particular use for PLA.
     
    For CAD, I've also been looking at TinkerCAD.com (recently purchased by AutoDesk), SketchUp (Google's CAD offering), and AutoDesk's free 123Design to do my own designs.
     
    Slic3r is an open-source... well... slicer that I've been looking at. It's in active and sponsored development, so seems to be getting steadily better.
     
    Some time down the line, I may try running OctoPrint on a RaspberryPi as a web-interfaced combination slicer and G-code generator.
     
    I feel like I'm getting into 3D printing just as it's reaching, not maturity, but maybe later childhood. I am excited to see what's ahead for home 3D printing!

    Just some tips here, might be useful for anyone getting into 3D printing.
     
    Some discreet step to creating a 3D print.
     
    1. Design in CAD software and export to STL. (Autodesk Inventor / SCAD)
    2. Slice the STL in Slicer software to generate gcode. (Skienforge / KISSlicer)
    3. print with design using g-code interpreter (ReplicatorG)
     
    I print ABS at 230 deg C, hotbed at 110deg C. PLA at 235, 50 deg on the Hotbed. for PLA I print not less that 80mm/s, extruder will jam if the PLA stays too long in the melt chamber. for ABS, 60 to 120mm/s. PLA is 'similar' to ice, turns liquid when heated to melting point, ABS will become soft gradually. PLA produce print with sharper edge and more ridge details and is harder. ABS is more flexible and has a higher melting point, PLA will deform when heated above 90 deg C (citation needed). ABS cracks and warp during print, extra care needed to ensure there is no sudden temp change. tramming / levelling your print bed is crucial for a good print, if the nozzle is too close to the bed, pressure build up in the melt chamber will cause the filament to strip. if the nozzle is too far from the bed, print is likely to lift and warp. keep nozzle and bed clean at all times.  I kept a spare nozzle soaked in acetone. keep your plastic in a dry place, I out them in big ziploc bags with silica gel.

    If bluehash allows, I can print and sell some, cover some plastic cost, of course Shapeway's quality will be better.
     
    $2 each + $2 for handling  +  shipping + packaging, (air mail should less than $3 - 6 to 12 days, i have to check)

    they only ship UPS so they charge $6.50 for US shipping (per order not per piece so if you order alot, its still 6.50 for the "order")  $9.50 for shipping to the EU, and $20 for the rest of the world.
