Greetings all,
It seems the 50mm fan has stopped working on my printer, I'm using slic3r to generate the gcode and the fan setting is set at always on. Both the case fan and extruder fan work as always. I just printed a part and the bed fan did not come on at all. Is there a way I can check if it's a code issue or if the fan just stooped working?
Thanks in advance.
50mm bed fan not working
Re: 50mm bed fan not working
I'm not familiar with slic3r but I know M106 S0 turns the bad fan off so if there is a command line in slic3r try M106 S255 and see if that works.

Re: 50mm bed fan not working
Welcome to the forum!
The M106 g-code command controls the 50mm bed fan. One way to determine if it's a code issue is to open the g-code file that slic3r generated in Notepad (or equivalent) and do a search for "M106". Somewhere near the beginning of the code (generally, the beginning of the second layer) there should be a line that says "M106 S255". This line tells the printer to turn on the 50mm bed fan at full speed, which is what you want for PLA (0 is off, 255 is full speed).
You could also try simply sending that same line of code when you are connected to your printer, i.e. before you start a print (edit: like sthone said). If you send that command and the fan turns on, your problem is likely in the code. If the fan doesn't turn on even then, you may have some other issue like the fan stopped working, somehow got disconnected, etc.
Hope this helps a bit!
