Does anybody know what causes this crack noise at 02:00 and the upcoming error message? The heat bed is a new one… resistance is measured and fine. Any help welcome!
I have to switch off and on a few times, then its working
This click sound sounds like missing steps of the Z Axis…
The sensor is tough as hell. You should be able to drive a car over the heated bed and the only thing that will survive is the temp sensor.
Much more likely something broke at the connector to the board. You said you checked the cabling so the second most likely thing is you need to reflow the solder. Just heat up the solder under each of the 4 connections where that screw terminal block is mounted on the board.
The reason it is associated with Z movement is because something is soooo loose that just the movement of the bed up and down or the changing of angle of the cabling to the bed (even though it’s screwed down) is enough to make the wiring disconnect briefly.
You can power off the machine and hook up an ohm meter to the temp sensor cable where it connects to the circuit board and measure the resistance. It’s supposed to be about 108 ohms at room temperature. When it’s bad it will be over a thousand ohms. But it’s so much easier to just take the bed apart and reflow the solder and remove the 2 temp sensor wires and screw them back in again tighter.

hahaha… nice! I was postpone switching my UM2 nozzle to olsson block because I thought it would be a headache to change that temperature sensor. Now I just need to find someone that send it to Brazil
Okay, after endless hours I got it …It was a Problem with the cable connector to the sensor at the heat bed…from tome to time the Connection was disturbed by movement of the cable…I soldered it and now that Problem is solved for some days.
