Today's progress

Not a lot, but every little bit helps. I found I didn't have the proper length M3 screws to mount the motor in the extruder. Used some long ones to get it good enough, bumped up to the latest version of Marlin and tweaked the calibration for the extruder - since the new hobbed bolt has a smaller effective circumference, it was only extruding 95mm of filament on a 100mm command, so I had to multiply steps per unit by 100/95, which put it dead on the money.

I think this extruder is going to work very well. I just need to bolt things back together after I get the right length screws and I can try another test print.

Once I'm done with this and am producing good prints, I will feel comfortable printing parts kits for others. I didn't think I'd want to make parts for others if I hadn't used a set I made myself to produce a decent printer.

I'll have to remember to get some M3x12 and x14 screws tomorrow. I've been trying to build a stock of both mechanical and electronics parts but around here metric screws are sold one at a time so I probably won't get a whole lot of those. SAE stuff of larger sizes is sold by the pound which is lovely. Maybe I can find a web reseller that I can get a decent quantity of metric hardware from for a reasonable price.

Audiobook finished

The Pride of Chanur by C. J. Cherryh

This is another of those books that I'm sure I'm the last person I know that hadn't read it yet.

Decent world-building and good writing as I'd expect from Cherryh. No great surprises, just setting up an interesting universe.
