there are a lot of things to keep in consideration when you print and usually it's not the machine fault
and ultimately when you think you did everything right and still print like shit you will find out that the PLA you just bought was a bad batch or the pla printed just fine 1 month ago got too much humidity and now print bad etcetc
I joined 1 year ago more or less i have my machine since Sept 2015 and I made at least 10 architectural model of decent size with some challenging large flat surface and annoyingly weak wood PLA (i tested more then 15 wood pla)
The machine is great but the challenge is there but i grew more accustomed to accept the challenge and learn from failed print then i was when i started
I learned to love 3d print and my M2 but i would never dare to say to a newbie it is easy with this machine just try... it's pretty hard and you need to love it or forget it
