So, at 30,500 steps per mm in the GRBL driver I'm getting repeatable
movement in 50 micron steps from the control panel. Given I'm 1/256th
stepping the m...

Thanks!!! I don't have a lathe but I am trying understand what could I do with it.
I was curious on how to make the worm pulley since NopHead had very good results using it.
I whish I could make my own gears, and make the same extruder as NopHead...

You might have better look turning 'Macro' mode on when taking close ups with your camera rather than drawing a face :)
Hey shame about the worm gear, excellent lathe piccys though.
Did'nt the shoulders on the worm gear get in the way of the pinch roler ??
If they did it might explain some poor grip.
Why did you machine a V shaped groove before tapping? I think that is why you don't get enough grip. I just started with a cylinder and wound the tap in until it made an approximate semicircular groove.
I don't think your video is nearly as bad as you make it out to be. I do have to admit that camera shake annoys me in may of the videos that I see online, but yours honestly wasn't bad.
I'm glad to hear nophead chime in, and I DO wonder what's really needed to make this work right, since I'm planning on trying amost exactly the same process.
What size tap where you using? Do we know what size tap nophead used successfully? I think the 1/4-20 taps I work with are a might large...
I used M3x0.6 and M4x0.7 as blogged here: hydraraptor.blogspot.com/2009/04/all-torque-and-no-traction.
