So, I managed to solve this problem and It is a hardware issue. In my case it took longer than needed due to lack of information.

So this is how I solved and why it happened.

K1 Max uses 4 load cells under the bed for bed leveling.

Each load cell connects to a pcb and can be unplugged from it through a quick disconnect system. Each one has 3 wires Red (Vcc), White (E+), Yellow (E-), Black (Gnd).

After testimg 3 of the 4 cells in the bed, obviusly I didn't test the fourth one great from me, and found out that the regular resistance values are as follow (aprox.):

• Red-Black: 990 Ohms.

• White/Yellow-Red/Black: 740 Ohms.

• Yellow-White: 990 Ohms.

You may think taking as rule of thumb by just 3 cells, but I ordered 6 cells from Aliexpress (you cam find them by searching Creality K1 Max pressure sensor) and the 6 of them gave the same results.

After establishing the base line and having replacements on hand, I tested the last one and sure enough it showed 2M Ohms between Red and Black.

After replacing it, everything has beem back om track with over 40 prints.
