![]() dc42s delta is 300mm diameter, 480-540mm print height, and is 1m tall. The simulated/calculated diameter on the end (30mm from the center) was 14.906mm. Deltas scale poorly, even more so when youre talking 1m Z axis- My delta is 720mm tall, and has a build height of 280mm. The data I used was:ĭistance from driving pulley to anchor pulley (must be constant) is 150mmĭriving pulley diameter is 15mm, grove steep is 1.5mm (like thread) and there are maximum of 20 turns on one side. ![]() And surprisingly got taper instead oval.Īnd to be precise just really small taper. Haydn huntley's rods use a 15mm zylindrical. But maybe a pure magnetic system should work enough if you use big enough magnets. I already have the rods with steel balls on each end, so I might give it a try. They generally fall into two common design categories the traditional Cartesian design, which involves an X, Y and Z axis, and the Delta design, which is where the printing head is suspended from three arms over the print bed. The design of the Cherry Pi IIIs was the one that gave me the idea of using the fishing line and hinges to secure carriage and effector. Description Specifications Customer Reviews You may also like Description. A large number of RepRap models have been created for different purposes. Does anyone proved that already? My math is not the best one (well it is on low side) but I did try to simulate with simple python script. Reprap Delta Kossel K800 mini Metal magnetic effector + Chimera hot end assembly kit/set for DIY 3D printer alunimun al. Franklin firmware, while developed for all 3D printers, is a perfect fit for the. It is designed to be even easier to assemble, having around 50 fewer fasteners, requiring less wood, fewer printed parts and fewer cables. So I try to calculate that "cigar shape" pulley but surprising found that pulley in not oval but just tapper!. The Athena II 3D printer is a RepRap derived from the Athena Delta Printer, requiring CNC router-cut wooden parts. And I find same idea discussing in some other forum (here are stolen drawing). I got idea to shape driving pulley to compensate that. There are no slippage but tension change dependant of motor position. The other side have line joined on center of driving shaft and then all needed length are wrapped around shaft. On one side there are just turn around drive wheel and possibility to line slip. I read a lot about spectra line for drive instead of timing belt.Īs I read the major trouble is how to drive it.
