SpeedDrive documentation PROJECT MOVED TO GITHUB. VISIT GITHUB REPO FOR LATEST FILES AND UPDATES. The motivation behind creating the SpeedDrive mount was to extract maximum performance out of my ender3 with mostly stock parts. Print FAST with near-perfect quality. After pushing Bowden to its limit, I came to the conclusion (like many others), that sharp and accurate corners are simply impossible with a Bowden setup. Bowden setups are great for models with curvature, but for my particular uses, I was printing precisely engineered parts that often needed to fit together. Bowden setups produce poor corners because of imprecise linear/pressure advance due to play and friction inside the Bowden tube. This can be reduced to some extent, but never entirely eliminated.I started playing around with various mount designs and found them to be inadequate. The corners were good, but ringing and vibration prevented high speed printing and good bed adhesion. The orientation of the motor and distance from the X extrusion was not suited for sufficient inertial dampening. In creating this mount, there were two operating principles:Orientation of the motor (shaft) should be perpendicular to the X extrusion for good absorption of rotational inertia. The motor's centre of mass should be as close as possible to the middle of the X extrusion for absorption of its significant linear inertia at speed. Staying true to the operating principles, my solution was to mount the motor from behind the carriage with the extruder facing forwards. Speeds upwards of 100mm/s and accelerations of 3000+ are not only possible, these are real operating speeds that I have been using day to day for all my prints (see image of xyz cube). By no means is your printer guaranteed to get these results right off the bat, start at 1500accel and work up from there. There are now several designs and remixes claiming to be an improvement over the original SpeedDrive. I am all for innovation, however many of these designs violate one or both of the operating principles inherent to the SpeedDrive design. For this reason, I would not recommend any design or remix not explicitly listed on this page. Remixes and improvements are welcome however I encourage designers to stay faithful to the design principles. IMPORTANT NOTE!!The only downside to this solution is that the stock motor will slam into the frame unless the X endstop is adjusted. Therefore, I have also designed a 7.5mm endstop spacer that fits onto the carriage. This will shorten the bed in the X orientation by roughly 1cm on each side. In slicer, your Ender's bed size should also be changed to 200mm in the X direction.See the remix by dascook for reclaiming lost X space if thats important to you (BMG only, pancake stepper required).Also, for very tall prints you will need to extend the e-motor cable and adjust the printer's Z height in slicer to 200mm. DEMOThis is a demo of a near-perfect calibration cube printed in 13minutes using Klipper firmware and pressure advance (see picture). When my ender was still Bowden, I could only manage a 15minute cube with acceptable results. I don't know what to make of this because in theory, the Bowden setup should get higher speeds but it appears that superior corner performance and placement of the SpeedDrive negates the weight disadvantage. This is actually not that surprising because PRUSA printers are known to print at these speeds with similar quality. SPEEDDRIVE PRINT AND INSTALLATIONPrint with the flat part down, at least 4 walls and 50% gyroid infill. Enable support roof. 0.2 should be fine. PLA is fine. I recommend tightening the mount first without the v-wheel sleeves. This will

Приветствую всех! Последние годы довольно часто обсуждаются проекты open-source телефонов. В основном это всякие смартфоны на Linux, иногда припоминают и всякую экзотику типа OpenMoko. Но есть одна...

This is a library function that fits between linear_extrude() and rotate_extrude(). It takes a 2D object and extrudes it in a spiral. Unlike linear_extrude, the 2D object is perpendicular to the path of the extrusion.This would have been much easier if OpenSCAD would allow me to access the points that make up the 2D objects the function is operating on.Comment out the example before using this as a library. I left it uncommented so that Thingiverse would show a picture of the example.Update: I found a bug where when the radius was less than 20, it would fail to generate anything. I found that the calculation inside the asin() function was resulting in 1+1e-14 which is not allowed for the asin() function, so it was returning nan. I have limited the result to a range of -1 to 1 to fix the problem.Update 2: Adjusted the size of the spiral segments so the segments slightly overlap (eliminates gaps in spiral). Added render() to segment because OpenSCAD was complaining of too many objects, and getting slow. Changed atan() to atan2() to avoid potential divide by zero. Added version number to file. (this version is 1.2).Update 3: I added the capability of doing flat spirals. I also found that the Starts variable was not working. I got that fixed. This is version 2.0The tapered spirals are not as smooth as I'd like.I'm also thinking of re-implementing this in a more generic way.I recorded a screen capture as I updated the file: videoThe image and STL file are the test objects in the library. If you import the library with the "use" function, these test objects will not be included.Update 4: I can't seem to leave this one alone. I re-implemented the spiral extrusion as extrude_spiral() and made a wrapper function named spiral_extrude() that calls extrude_spiral() for backswords compatibility. I did this because the previous design did not handle the equivalent of rotate_extrude() (the way it is documented with the Angle parameter instead of the existing function that only does complete circles). I also fixed a bug where the spiral was always an integer number of segments and ended up taller than requested.Update 5: Updated to version 3.1. I found and fixed a bug where the extruded object would extrude one more step than requested. From this point forward, extrude_spiral() is the preferred format, and spiral_extrude() remains as a wrapper of extrude_spiral for backwards compatibility. I hope I am done with this, and that this becomes obsolete when the next version of OpenSCAD is finally released.
