Nice, yea my current one goes at 9-10 frames between each, I have a new version with the beta that is consistently 8 (fastest possible without two sets of shooters), and less bloated overall, you can take a look (in the beta).
@DCBloodHound(View Post) It deals specifically with spark speed consistency (and some ARAY firing speed), so your copier may need slight alteration. Yours still works 99% but Minishooz's does not work at all (although still only timing related).
