Bedheater not working

[urosv 0]

Heater impedance = ~4ohm

Voltage on heater cables: 24V (output at arduino side and voltage on heater)

Current: 0A (no current)

 

----------------------------

already

1. changed cables

2. resolder wires at bedheater

3. re-measure twice everything

 

Any suggestions ?

Hi,

Is it possible to control the impedance of the sensor?

On my ultimaker2 i have 110 Ohm for the sensor.

Sensor impedance is 107 Ohm.

Okay.

maybe the other idea is to measure directly on your board (if you have not already done it ? 

 

A+

I fixed the problem. Since all measurements indicated that everything is ok i tried last one thing. The junction part of the heater cable was overheated and contact ware overheated also, so i replace the wires and solder them directly to heatbed and on the main board at the opposite side. So bad junction was the problem !

Hi,
I'm happy to hear this ? .

 

Have a good day!
