calibration problem S5 after upgrade 6.2

[team4architecten 0]

Goodmorning! After upgrading the 3d printer S5 to the newest software 6.2.0 we suddenly have a calibration problem. During the automatic calibration proces the print area starts calibration on the first nozzle which works fine, but on the second one the printer-bed itself stops about 1 cm before hitting the nozzle. Then the error occurs that there is too much difference between the nozzles and the machine automatically stops the process... downgrading to 6.1.1 did not help. Printer is a mid 2020 S5. Hopefully somebody can help us out. Thanks in advance!

Have you placed anything new in the area of the printer lately thats electronic? A lot the time the auto leveling failing in that manner is from interference (even static from your own body can sometimes make it fail)

 

Outside of that i have found sometimes just unplugging the wire to the sensor in the back of the printhead and plugging it back in can help and even something as silly as just to open and close the front printcore door.

Have you checked the small cable in the back of the printhead (looking from the front in the middle behind the cores, a red and white wire that connects to a PCB on the hatch). That can break, I had this recently and it did the same, I then discovered that the white wire broke off, the auto leveling worked sometimes, I guess when the wire had by chance some contact. It's kind of difficult to spot if you don't know it can happen.
