I’m testing printer with xyz cube 20x20x20mm.
I still have bit problem with z-axis homing as assembly holding two rods is sometimes hitting z-stop switch. Longer screw holding switch will do it though.
Also bed might not be leveled correctly.
I put up both extruder (200ºC) and bed (60ºC) to higher temperatures.
I slowed extruder speed as well.
I couldn’t find pictures or K8200 perfect prints but I think ones which I’m getting could be better.
Heated bed stopped heating up, had to resolder NTC thermistor.
To fix Z-axis problem I had to lower part holding Z-axis motor.
I set slower print speed.
Here is result:

I lowered layer size, print and extrusion speed. Is this best print one can get out of base K8200?
I guess so.
