[BUG] selftest does not detect wrong connected fans

Open MLWORKX opened this issue 2 years ago • 2 comments

Printer type - [MINI]

Printer firmware version - [4.3.4]

Original or Custom firmware - [Original]

Optional upgrades - [Filament Runout Sensor]

USB drive or USB/Octoprint [USB only]

Describe the bug Both fans -print fan and hotend fan- have a 3pin connector which is plugged in on the board next to each other. Got a replacepent board and mixed them up: plugged the hotend fan in the print and the print in the hotend Selftest was successful and could print several hours but then had a heat-creep.

How to reproduce Change positions of both fans and run a selftest

Expected behavior The routine at self-test should test the fans seperately as this may also happen at factory. Yes, this was my fault but would be nice of the selftest could indicate this.
