Print fan calibration fails
Hi All,
1 week ago I received my MK4S kit and started the build during the weekend. All looks very nice and the difference between the MK3S (my previous printer) and the MK4S are a big improvement. Although some of them are just - but a lot of - (small) details in the design. The big changes are in the printhead and electronics.
After assembly I started the 1st calibration - fan calibration. Unfortunately this one failed directly. The print fan reaches only 4800rpm but required a higher speed.
I tried (after updating the firmware to version 6.1.3):
- checking the cable loom
-checking the "love baord"
- multiple repeats of the calibration (with multiple I mean at least 50x) with mounted fan
- multiple factory resets (complete and calibration only - at least 10x) with mounted fan
- repeated the calibration and factory reset with dismounted fan
Contacting (the disappointing) support from Prusa directly --> no results, no action, no spare parts send until today (4 days later) and still unable to use a new printer. Even after the request to send a new fan and love board (on my own expenses), no reaction/action anymore.
So I continued my tests:
- very small test print of enclosure cover (1 pcs) in PLA -- > works
- very small test print of enclosure cover (1 pcs) in ASA -- > fails due to fan
Therefore I reach out to this forum. Has anyone experienced the same issue? Did you find a solution? Please let me know.
Thanks a lot in advance.
