Even though I used after calibrating it to my F1 ultra. I engraved one pencil and it the jig was very helpful.
I ordered multiple jigs for my f1 and so far I'm impressed with the quality. I've been able to increase my lasering significantly. If more jigs come out I might order them.
Thanks Sam for all you do in making all of your jigs it made my lasering much easier and faster
I highly recommend all your jigs that you sell (Mahalo) keep up the great work you are doing
