I found with my printer the ratchet wheel the inner teeth were too rounded and I tended to have 1-2 teeth where the ratchet would not catch to continue driving the wheel around (without any drag from tape yet even).
I modified the design to have these inner teeth be more aggressive to ensure a complete ratchetting. This required a minor trim to the advancement tongue with an exacto knife but works reliably now
