Would someone confirm the sizes of the Feeler Gauges? I get the 1mm gauge, but what is the size replacement for the paper card? When I measure the card it is 0.15mm, which wasn't mentioned here at all.
I just bought my first 3D printer, a UM3, and I am constantly fighting a bed leveling issue. I am a total novice. My PLA just doesn't want to stick to the bed and will have little raised lines in the brim. If I have a brim of 7mm, as suggested in Cura, I get waffling in the brim and it will release from the bed and stick to my print head. So I use a 3mm brim and that works better, but I don't get a smooth edge to the brim print and it will still release on occasion from the bed. I constantly manually level and then on occasion use the auto level option and it still doesn't really get better. I want to print really small items and push the resolution Z layering down as far as I can get it, but do occasionally print larger item. Am I doing something wrong being a novice? I work in microscopy at work and get critical stage leveling, but this is just driving me crazy. One of the reasons I bought the UM3 was I thought it would minimize these sorts of issues. Please help!
