I built Marlin 2.0.9 for Wanhao Duplicator 6. It probably doesn't matter which printer it is, even if it's also black.
There are also several problems. One of them -
1. when heating the bed and nozzles, the temperature crosses the value of the specified threshold several times. Then Marlin considers that he has reached the specified bed and nozzle temperatures and proceeds to the next steps.
Perhaps this is due to some parameters associated with hysteresis?
How to fix?
2. The printer has an inductive sensor installed. After calculated and set (it was difficult) offset Z, he decently printed out the test part. After turning off, the nozzle again did not reach the bed by 0.1mm
3. Sometimes weak extruder feed. The extruder gear at some points rotates in turn in both directions, small chaotic twitches. I don't see the voltage adjustment on the motor drivers, maybe they are on the underside of the PCB?
