Brook shows how to swap out the old 1/4" acme rod for an improved 8mm 4 start Acme rod on a Printrbot Plus. Less than 15 minutes and you are good to go. Don't forget to change the steps per mm for the z axis. And be mindful that your z offset may have changed. Make sure your ending gcode moves the hotend out of the way after a print, too.
