Indeed, the first layer is crucial. For me, 0.1mm is too thin and gives occasional blank areas (=uncovered), 0.3mm is too thick and reduces bonding, and 0.2mm is best: this gives good coverage and good bonding (glass bed). But for other materials, beds, and printers, it could be different.
Normally the bottom looks like this (ruler is in mm and cm):
For PLA and printing on glass, wiping the glass with a tissue moistened with salt water greatly improves bonding, compared to printing on bare glass. See my old manual here (and then scroll down a bit):
For me this works very well on long flat models like rulers and calipers. Not very suitable for narrow high models like poles: they tend to get knocked off. So, stay with the printer until you know by experience how well it works for you.

We don't often release an alpha version of Ultimaker Cura... So what's different this time? This Alpha contains such a huge slicing engine overhaul that we really need your help!
We wish to celebrate and honor the innovators that push forward the field, technology and world. We opted to not present it as a competition or ranked list. Every innovator has earned his spot on that list in their own way. We also look at the 3D printing industry as a whole and not limit the list to those only using Ultimaker.
