No tips or tricks- I just wanted to let you know you are not alone. I have 3 printing sessions under my belt and so far my biggest issue beyond not knowing a damn thing is DUST!
I have learned that without a grain magnifier, I have areally hard getting anything in focus. I don't know if relying on it is going to be detrimental, but for now...its the only way I can be sure of anything before I print. Have fun. looking forward to learning along side of you. -Karen
