Re: [Emc-users] Making taper lock hubs

I can't see how lathe alignment could affect your angle. If you turned the OD running forwards with the cutting tool in front and bored the ID running in reverse with the cutting tool in back, then yes. But if both were done with the spindle going forward then the tip of the cutting tool is

That's a clone of a Flashforge, which is a clone of the Makerbot Replicator (old Replicator, not the new one which they also oddly called the Replicator). It's upgraded in some ways, possibly downgraded in others. But it is known to work pretty well. My original Replicator is still excellent

I have done relatively little 3D printing myself. I do run a community hackerspace with a number of 3D printers, most of which are broken. Many, many cheap 3D printers just can't work out of the box. Badly designed linear axes, terrible ratsnest of wiring, extruder designs that do nothing but

Re: [Emc-users] 3D Printers

Parts can be quite strong. Although, I've seen plenty of prints with a bad layer (can be as simple as the air conditioning kicking in and shrinking the plastic suddenly). You can print out objects that would be difficult to mill, such as things requiring 5-axis milling, exotic holddown
