Hi.
I have problem. My friend build k8200 from parts and I’m trying printing on it. But there is one issue: heat bed won’t reach 50 degrees of celcius. Max is about 45, and while it printing temperature drops to 30 or even less.
Here’s a couple things to check.
Check for a partial short or high resistance in the power wiring to the heat bed. With power to the heatbed on (verify that the LED is lit steadily on the controller board), you should be able to measure close to 15 volts DC across where the power wires are soldered to the heatbed PCB. Those wires are the two groups of 4 individual wires from the ribbon cable soldered together to make bigger wires. If you aren’t seeing the 14-15v, there may be an issue with the wiring to the heatbed, which you can beep out with the multimeter to check the continuity.
Another possibility is the little thermistor is either not wired right or damaged, making the temperature reading the controller board sees inaccurate. Does it read the temperature of the room correctly before you turn on the heat to the bed? It should be the same temperature of the cold extruder.
Environment is everything to these machines
Make sure you room is warm enough.
Make sure there is no air being blown across the bed.
This is a large surface.
It does not take a lot to cool it down.

Yes, but there’s something wrong if it can’t achieve 50 C , even in a frigid room.
Sorry,
I don’t agree with that.
I tried starting my printer in a room that was around 60F and the bed would not come up to temp
After I warmed the room up it worked properly.
This is a large surface that can be easily cooled
