    Fun weekend project! - Mini Marble machine.

    Yes, the original design is on thingiverse. I dont have any geared motors so modded a hobby servo and redesigned the mount for it.,
  2. 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.

    Getting a RigidBot 3D printer, help me learn?

    my avatar? My work pass when I did a shoot at florida, universal studios.

    First etch & surface mount!

    nice, the last I etch was 10 years ago.. did some milling and decided to just go with the Chinese supplier.

    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.

    Makerbot support responds vey quickly with answers that you don't need. Support only knows the surface and they make it too tedious for you to follow up. Heading down to the local frame maker for enquires when I have the time.

    I have not tried Slic3r, I recently switched to KisSlicer and it is amazing, I do hope it is open-source and I am willing to pay for it, basically it has some feature that cannot be replicated in others. Yeah, it is exciting, 3D printing is moving so fast that you have to relearn many things as you go along. I am excited to share your experience and knowledge and will do my best to share what I know. Currently I am upgrading my Bot to fix the issues that Makerbot refuse to fix and forgotten about upgrades for Rep1 user . Next upgrade is a Glass bed and replacing some part with aluminum- I just got a quote from a local company for a small piece Boroslicate glass at $350, that is super crazy.

    actual print is about 10 to 12min, printing slight slower for better quality. it tends to overshoot when it goes to fast and you will get blobs on the corners. every different roll of plastic need to be treated differently and calibrated accordingly.

    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.

    3D printed bumper.

    Yellow, Natural, Red, Icicle Blue, Green, White and Black. Will put all this up for POTM prizes if it is ok with the BOSS.Let me know bluehash!

    There is no "catch" just a bump and friction fit, you snap it in and it stays.

    3D printed bumper.

    Dont worry about that.. haha. 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) Will send some to bluehash for POTM give aways.

    3D printed bumper.

    will print some in other colors when I have the time.

    3D printed bumper.

    FYI. the above is printed with PLA, natural color.

    3D printed bumper.

    No problem, actually it is a good idea. I don't mind printing some but I am located in Singapore, shipping with not make any sense here. Price for shape-ways comes includes shipping?
