I used an Anet A6 printer I paid $180 for the printers Here is a video of the first time I tried runubng with not only four 3D printed pulleys but two print belts. I did not expect the printed belts to work but they seem to last for a couple of hours. I was expecting failure but, no the pulleys are near perfect and will last for years. The best idea was at first a joke but turns out to be a good way to verify belt size before placing an order for a real belt. The key has to make the printed pulley with a 24mm steel hub and put the set screws in steel threads. Fully printed pulleys did not work well but these hybrids do. The mill has a 30T, 60T and two 40T hybrid pulleys made from plastic rings pressed over 24mm steel cores https://youtu.be/wupYP2NNsXI https://youtu.be/tlMTksuOuZQ -- Chris Albertson Redondo Beach, California _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
