  1. Well looks like it was fixed at last !
  2. Any Youmagine dev around to take a look at this ?
  3. I've uploaded the relevant files on YouMagine: Microspringer RC Tug boat
  4. Hi, I've just published my first design on Youmagine (Yay!) and wanted to use the embed code to link to it from my little web site. Here's the embed code given by Youmagine: But Chrome, Firefox won't embed anything. Chrome's console gives me the following reason: Refused to display 'https://www.youmagine.com/designs/7312/embed' in a frame because it set 'X-Frame-Options' to 'SAMEORIGIN'. The server indeed send that header: < HTTP/1.1 200 OK< Server: Cowboy< Date: Fri, 24 Apr 2015 13:28:35 GMT< Connection: keep-alive< Strict-Transport-Security: max-age=31536000< X-Frame-Options: SAMEORIGIN< X-Xss-Protection: 1; mode=block< X-Content-Type-Options: nosniff< X-Ua-Compatible: chrome=1< Etag: "3da7d8cea888a91a2f2c864c700368f2"< Last-Modified: Fri, 24 Apr 2015 13:03:24 GMT< Access-Control-Allow-Origin: *< Access-Control-Request-Method: *< Content-Type: text/html; charset=utf-8 From what I understand SAMEORIGIN means the browser should render the iframe only if called from the same domain (ie: youmagine.com) which is quite the opposite of what we want ?! Could anyone look into it ? Calimero
  5. I've come to think that it might indeed be a simple connection issue. I've wiggled the cable on the bed end and have been able to move the bed up/down multiple times and run a 1-hour print. The brief connection issue causes the printer to go into error mode. Maybe that brutal change somehow interrupts the code running the stepper motors for a few cycles hence what sounds like a missed step ? Anyway I'll try check the cable tonight a bit more carefully. Good to have the build manual. Thanks.
  6. Hi Tonight after a few weeks without any printing I switched from PLA back to ABS. I then heated up the bed and initiated a new print. Once the bed and nozzle were at the right temp, the bed was raised to start printing. But that's when things went wrong. As the bed was moving up it sounded like a missed step and I was instantly graced with a "Temp sensor bed" error. I power cycled the printer and the print sensor seems to work and give credible figures. Here's a video of the bed being raised and lowered. At 00:35 the weird sound can be heard (and again the printer goes in error mode). Surprisingly I've been able to lower/raise the bed a few times without problems. But most attempts (usually raising) fail with that weird noise. Note: buzzing at 00:15 is unrelated to the printer . I just got a text on my smartphone... Cables going to the bed seem fine and are out of the way when bed is travelling up or down. Any idea where to look ? Thanks
  7. Hi folks ! Happy new year by the way ! I managed to launch both my latest RC boats this past Sunday. And one of them of course was this Microspringer. Microspringer on the pond Microspringer on the pond Here's a short video of the thing weezing around (and even doing some push work !).
  8. Build log 2014-12-30 : Handrails, paint & fenders The first Microspringer is now almost complete. Truckable tug - Inspiration for the color scheme Shabby paint job - TX in the background for scale Fenders - 3mm rubber cord all round - Tyre inner tube on push-knees Handrails - 1.00 and 1.50mm brass wire Rudder was enlarged giving a little bit better maneuverability (trials in the bathtub !). Just have to adjust a few things (paint the exhaust, add a couple stickers or lettering ...).
  9. Right now I'm into RC model boats but I'm ogling at drones mostly for aerial photography. But that thing looks sweet ! And the video really gives a "bird-like feel". Good job, very tempting !
  10. Build log 2014-12-17 : Locking tabs Locking tabs - Bow end first Locking tabs - Locks at the stern Tabs installed - Tabs acetone-welded in place Wheelhouse secured - Snaps right in place Those tabs work surprisingly well (first attempt!) and positively lock the main hatch in place while still keeping everything easily (no tools) removable to change the battery. Push knees were also "welded" in place. I've printed an exhaust pipe. I'm still unsure whether I'll install the bulwark or not. Time for MOAR SANDING. Then maybe LED navigation lights (powering them from a CR2032 battery although 3V might be a little on the low side for white LEDs ...) and brass railings for the push knees and the wheelhouse. Then a lot of prep work before painting !
  11. Build log 2014-12-13 : Deck and wheelhouse Wheelhouse was printed. Maybe I'll add working navigation lights. Depends on the overall weight. Lots of work to do on the wheelhouse (sanding ...). Basic wheelhouse - Deck with bollards - Bollards are strenghened with 1mm piano wire Deck (underside) - Piano wire will get a dab of methyl-methacrylate glue Simple cross bollards were printed. They were drilled to get some extra 1mm piano wire through. Small pieces of ABS were "acetone-welded" under the deck where the bollards go. Piano wire protrudes under the deck and will get a bit of metyl-methacrylate glue.
  12. Hi, Just a few updates (including stuff I forgot to post here). Build log 2014-12-07 : Improved hull, RC equipment Hull went through an aggressive diet. Walls and bottom were thinned. All in all approximately 30% shaved off. Minor issues (clearance for the motor, ...) were fixed. Printing hull Rev.30 took a little under ten hours (overnight, as usual). Print included an integral servo mount (ie: printed right with/within the hull) but it was too skinny and broke off too easily. I then decided to print another strong servo mount and "acetone-welded" it in place. Hull and deck (Rev.31) - 3D model of what was printed Superstructure design - More design required; getting closer Side view - Redesigned/strong motor mount 3D printed hull with RC equipment - Tests in bathtub were promising Underside - 3D printed push knees and rudder arm Deck and push knees - Mock installation RC components are installed (with hook & loop / Velcro). Servo mount is a good fit. RX, ESC, motor and ESC all work great. Even on a single LiPo cell motor seems a little fast but ESC allows smooth starts and has linear throttle response. Low pitch of the prop also helps a lot. Motor was soldered to ESC to save weight and limit clutter. Servo plug on ESC was replaced with a 1.25mm Molex Picoblade one, to fit on the RX. Rudder will be redesigned to get a little more surface (towards the propeller) although steering is already very decent. Weight so far (including all propulsion, RC components, battery, push kees, deck, beam ...) is 149g (5.25oz). Previous hull (barebone) was 126g !
  13. Hi guys and girls Technically this isn't my latest print (there's on page 75. After a few problems with my UM2 (clocked nozzle, then I broke the temp sensor when trying to take the hot end off ...), I'm now printing ABS with decent results. Still some retraction/curling now and then but I tend to adjust my models and plan some extra material I can sand down. Well here's what the wheelhouse on my model tug looks like (only lousy cellphone pics, boats are at my parents' and I hadn't my DSLR/tripod with me ...) : The bigger tug is the "Odin". Wheelhouse was designed in SketchUp and printed in ABS. There are actually four parts: the wheelhouse itself, two doors (with hinges) and the roof. Handrails on the roof are brass though. ABS parts were brushed with acetone, then sanded and primed, sanded again, primed again, sanded again and finally painted. The wheelhouse on the small tug is also 3D printed but the print was actually pretty bad (formfutura abs) and had to be rushed for an upcoming event. New wheelhouse is already printed and now has to be assembled. Just as I was painting the wheelhouse for the Odin, my phone rang: I got an email from a fellow RC boat enthusiast who had the same problem as me: he was working on the same kit and the wheelhouse had gone missing. He had come across my web site where all of this is documented and asked whether I could give him my STL files so that he could have a new wheelhouse printed for his model. Nice timing ! At least I knew my model was good and fit !
  14. Nice ! Way quicker than my 12hr print ! We also have one of these DIY vacuum-forming rigs lying around at my RC club's workshop. Not sure it's still in working condition though. I've already been on your website a few times, looking at your barge kit. A little too small for a standard springer. We also have CNC cutting machines and I'm just done cutting the main parts for a 1200x40mm barge for my springer (out of 4.5mm plywood). But once my Microspringer is up & running (190x85mm), your 1:50 barge might be a nice match ! And your Stan Tug 1606 1:50 looks sweet.
  15. I took the hull to the pond yesterday and towed it with my "fullsize" Springer tug: Looks nice but way too HEAVY. I'm going to make the hull thinner. And I'm waiting for RC components (receiver, speed controller) ...
