No updates to the printer yet... but thanks to the awesome ERRFlings from Nova Labs I had some time at the booth to do a better video on the PrintShift ejecting parts.

In short, raising the Z axis pulls the string which actuates the rack by rotating it into the pinion. At that point, the printer's Y axis is shuffled backwards and forwards 90mm at a time to roll the part off the bed. The pinion only drives in one direction thanks to an integrated oneway bearing so as the bed moves forwards it advances the belt.

The gear ratio between the pinion and the drive roller is 1:6 so each 90 mm cycle advances the belt 15mm. This is still very early in the life of this ejector I kept the speeds are low and slow so that it doesn't hurt itself while on display.

Bonus ejector at the end!
