I recently got a 350$ 3D printer for my birthday. It is a Micro 3D printer, or an "M3D" printer.
After two weeks, I have not gotten one successful print.
Problems:
Doesn't stick to print bed properly - I took some advice from youtube videos and just put Elmers Purple School Glue on the print bed, works great
Shifting and stuff - something that is supposed to be straight is completely shifted and tilted.
Doesn't stick to raft - causes a big plasticky mess
Extrusion - Running PLA at 240 C, sometimes filament literally just wont't extrude
fragile - my halfway completed prints are flimsy as hell!
I callibrate all the time, callibrating bed location and drive system with their automatic program.
wat do.
EDIT: BTW I use internal loading of filament
