I need to upgrade my firmware as my printer (Zonestar P802N) is shipped with an old firmware without thermal runaway protection. As I get more and more concerned of starting up a fire mid-night, I am willing to update to a new hardware/firmware combination (I will keep the old as a status quo in case anything goes really bad).
Now I have the options Marlin and Repetier as my first guess. Maybe other firmwares as well. My favorite would be Marlin for the moment but only based on what I read on the internet of the specs and the fact that Repetier closed part of their code.
What I do not know is: How do the firmwares perform with Octoprint? I would use a stock Marlin configured to my used hardware. Are there any drawbacks straight ahead?
