After upgrading my K1Max to fw version 1.3.5.19, my heatbed seems heat up less as expected.
Can this be related to the fw upgrade?
If I set temp to 70 degrees C, the bed hovers between 50 and 60 degrees, you can touch it for some time.
(on 70 degrees thats not doable without burns… 
)
The current and target temps are 70 degrees, but the’re obviously not correct.
(PETG objects keep detaching also from the bed during printing)
More users with this problem?
(I have to set the temp to 85 to get 70 degrees)
