Heating Bed only reaches 83°C

Hei all, can anybody help me in this: My heating bed only reaches 83°C but in the A30 description it should be max 100°C. What is my failure or what can I do?

I recommend that you use a multimeter to measure the resistance of the hot bed.
The hotbed watt should more than 260W

Okay, I will measure if I‘m in office but I think I can not reach the wires. What color of wires are for the resistor? What Ohm should the resistor have. If the Resistance is okay is there any way to increase the power? Is there a limit? I think the PID uses „Pulse-Pause“ - Is there a way to send constant 1 Signal to the heating bed to see if the bed reaches more than 83Degrees?

Okay, I measured the heating bed. The resistance is 4.2 Ohm. Is that right or is anything wrong with that?

Then it should be the hotbed issue.
It should be lower than 2.2Ω

Ah okay, so it is 24V when I use Ohms law

Okay, so next step is to go to my reseller?

Hello.

Yeah, but...

Heated beds are universal and have a 12V & 24V power connector. Check the configuration.

Okay _kaktus_ what do you mean with it? Do you mean the connector on the controller?
Anyway, if I have 12V and 260W the resistance should be at least 0.6Ohm.

Hi.

I mean, the leads on the heated bed.
But in fact the resistance of the circuit is inadequate.

Hei all, okay, I got the new heating bed, but also 4,2Ohm between 2 and 3. Between 1 and 2 it is 2,2Ohm but I think I have 24V right?
What if I soldering the wires to 1&2-3? I wondered if in this case the driver is strong enough.
