Small gaps where laser starts and stops each letter, any suggestions

Ok, I think I understand how that works, I will research it much more and do some more playing around. Using my other laser with a smoothie board, I didn’t seem to have to worry about it, I had never seen that happen before with that laser and I had never messed around with minimum power or understood what it was for, now I see how I can use it get a perfect setting dialed in. Thanks.
