Hello there, really sorry for the slow reply! Haven’t been at my PC for a while! Don’t worry about it, doesn’t seem to be anyone answering my question anyway xD
My recommendations for small parts is make sure you level the bed while its preheated. Levelling the bed cold means once it warms up, the aluminium bed will expand and make the gap larger between the nozzle and the bed. Use the preheat PLA setting in the menu for most things. Go around each corner with a 80gsm piece of paper a few times to make sure also, as changing one corner will effect all the others. When your done, give the bed a clean off with some isopropyl (rubbing) alcohol to make sure there isn’t any residue from your hands or dust lurking on the bed.
That should sort most issues but if you are still having problems then try printing with a brim. I like to use a 8mm+ brim for small parts that aren’t sticking very well. And if that’s still giving you grief then use a raft. There’s no shame in using rafts as some people might say xD A little rough successful print is better than a perfect failed print!
If you have any other problems let me know! I think i have come across them all with this thing now xD
All the best
