What kind of delta printer are you looking at? Most are designed for very low weight on the effector. Even with a direct drive, you still (probably) need some sort of filament feed tube into the...

Yay! First “successful” print. There are still some flaws in the printing but I think I can fix that with some small tweaks in the calibration. [attachment 24399 DSE_4812.JPG] [attachment 24398...

Could you solder a tab onto it instead of grinding a piece off? Maybe you could use a gear piece that had a drip slot, where you could drop a piece of hot solder and it would fuse to the spindle and...

@Jon: As far as I know there have only been 4 individual Simpson style printers that have actually printed. (I hope this year that number goes to 100s) You are #4 with a unique design nonetheless!!!!!!!!

IMO clamping on a M8 shaft will be more than enough. If all you have is a block of aluminum, band saw, and drill press then you can make a pretty decent coupler. Additionally there a few compounds...
