Thats cute. But that would likely need to be made on a resin printer as this one from what I've seen so far, simply cannot do that fine a detail. Someone was right, I did have "mold" checked. Uncheckd and new slice made, no other changes. But perhaps 3 hours to finish this one, 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. And no, its not loose on the hot plate. :-) I'll see if the next one works, in which case I'll swap motors and find out how quick I can tear the hub out of it. Big change from a nema 34 with a double flatted 14mm shaft to a nema 23 with a single flatted 8mm shaft. 30T on the motor, 42T on the 25mm Z single start screw... I have a pair of metal pulley's ordered. Cura its claimed can monitor and/or drive this machine thru the otg port, if I get the correct cable, but my 10 meter extension is usb-2, can someone verify that an otg adaptor plugged into a usb-2 hub will work?
