Quick thought on the teeth with a metal flange. Would it be possible to 3d print just the teeth and then have two metal flanges that make a hub and "enclose" (sandwich) the teeth?

I only print the our 5mm of the pulley. I'm printing four ofthem, four-up at a time now. > but its > up into the pulley teeth but the threads its laying are completely > random, no teeth, just a rough surface with no real pattern. Are these "teeth" the ones that engage the belt or the ones that engage the set screw? Printing a threaded horizontal hole is going to be way-hard with 0.4mm walls for this just make an undersized plain hole and then tap it by hand. Or just as well, let it try to make threads then clean it up with a tap. Vertical hones print better. With standard threads in metal, every cross-section is a perfect circle. A vertical hole is just a stack of circles, something the printer can do. But horizontal holes have "roofs". The printer can't print over air so it adds support material inside the hole. I'm sure this is what you see, In Cura's preview support is blue. It is possible to selectively turn supports on and off so the horizontal holes are not filled with support. But it is a lot of work I use a hex key to punch out the support from holes. If the messed up teeth are the belt teeth then I'm at a loss without a photo. > And no, > its not loose on the hot plate. : -- Chris Albertson Redondo Beach, California _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
