Fan Problem MK3.5S
Hello,
I've received my MK3.5S upgrade kit and I'm having a problem with the fan not being recognised. The test is not running (fail) .
What is strange is that the fan is working correctly.
- The hotend fan runs during the test- The nozzle fan rotates during the test.
have done a test print ignoring the fan check and everything is OK.
i'm started from a FYSETC Bear MK3S base to the MK3.5S upgrade.
I flashed the firmware with the latest version.
Can you help me?
RE: Fan Problem MK3.5S
I'm now having a similar fan self test issue. While upgrading to the Mk3.5s from a stock Mk3s my stock hotend fan's brittle old wires broke so I replaced with a FYSETC fan because it was readily available on Amazon. However, the new fan fails RPM self test even though it seems to work fine.
As a test, I repaired/spliced the original stock broken fan wires and ran the fan RPM test again and it passed. However, I don't want to reassemble with the old fan because the wires are too short now.
