@Emiliano Achaval , I noticed in a photograph of your shop that you recently posted (https://www.aawforum.org/community/index.php?threads/grinder-lights.16840/) that you have both the Robo Rest grinder platform and Stuart Batty's grinder platform (do you also have Stuart's set up gauges?). So a call out to you, and anyone else that has experience using both platforms, for a comparison. I would be most interested in how they compare for ease of use, accuracy, and repeatability. Thanks.
