What I've learned messing around with a 2nd hand Malyan M200, documented for my and others' future reference.
This is a simple brain dump after I spent a day and a half figuring out the 2nd hand printer my brother bought, I figured it might be useful to others as well.
First off, beware of the cables. This model is notorious for the Y axis eating the bed heater cables, which will, sooner than later, make the bed heater or thermistor stop working.
Our printer seems to have the exterior of the Malyan M200 v1, but seems to only run the Malyan M200 v2 firmware. This conflicts with the information available on how to recognize what version you have. Well, you figure it out fast enough when you start flashing firmware, only one works properly.
Malyan M200 series is one-to-one compatible with the MonoPrice Select Mini (MPSM or mpselectmini for short) series, white-label rebrand.
