I will pitch in assuming we like how LISA functions. Love the sides! Can you take a square on view of the nut at high res? I need to trace it to make the thread clamps and coupler. Also could we make...

I seriously doubt if these can be manufactured on a lathe without extreme experience. let's produce the first couple of prototypes and if all goes well we can purchase the tap and make a bunch of...

@Dannydefe A few ideas: Graphite loading: If there is not a heavy loading of graphite at the interface of the nut and thread, it will always be sticky, and require lubrication. Purchased Tap: Keep in...

QuotePeteD Would a spinning threadless ballscrew work as a filament driver? Or is the diameter of filament too unreliable? The biggest hurtle I can think of is that variation in the filament diameter...

Regarding filament drive: *For 1.75mm filament you need 604s or smaller. *Counter rotating could be done with bevel gears. *You could use the edge of the bearing instead of the flat to increase the...

The metal screws make this concept a better platform for the globular deposition modeling of metal welding (GDMm), as it could support a lot of weight! Add a worm drive, and it could really...

I just discovered the root cause of problems with my extruder has been too low a current to the motor so the gear would not drive the filament. Have to run the motor hot and cool it with a fan and...

I'd add some 1/2" sections of PVC below the bottom plate to act as legs/ supports. They would keep the ends of the thread rod from gouging up the table it's sitting on. I think it would look pretty...
