i notices that my PLA print have extremely bad quality since two weeks and notices, that the part cooling fan is no longer spinning. I remember a while ago that the Front Housing Assembly got knocked you and i reinstalled it while the power was on. There was some small spark, so i thought that the Front Housing Assembly is broken. But it seems there is more to it.
I already tried the followings:
As in Part Fan not working suggested: Cut the power (for 1 hour) and reconnect it.
Ensured that the connector is really on it (at least till the point i thing it could break)
Bought a new Front Housing Assembly (because maybe the fan or kable is broken)
But none of these helped.
How can i debug this to? Is there some kind of log in the firmware i can access to check what exactly is broken?
How much pressure is to much for the connector? I really applied a lot i would never do to other connectors.
You mentioned a small spark. So my first intuition would be that there is a cut somewhere in the insulation of the fan wire which caused a short circuit which then destroyed the MOSFET that is driving the fan. Take of the front housing and inspect the cable under a magnifying glass or microscope.
If my guess is correct, then the toolhead electronis board is defect.
Write to support.
Oh sorry, i had forgot to answer!
Thanks AndiS for the advice. I wrote to the customer service and we could resolve it.
After trying to make a good picture i notices that i’m not really the sharpest tool in the toolbox
While looking at the image from support and my toolhead i noticed that i managed to insert the toolhead-pins into “nothing”, while still be seated.
I dont know how I manged to do that 3 times over two weeks, but here I am, lol.
Well this saved me. I did the same exact thing you did, had it plugged into nothing.
I wonder if there is any way that the printer can detect whether or not there is a connection?
There was no error at all for me saying that the part fan was not connect.
Did the same too. The other two connectors with perfectly, but the fan one not so much. Trying to fix it, but I hope there will be better connectors in future printers.
Yup, this also happened to me. The printer was throwing error messages and they wouldn’t go away. I double, triple and quadruple checked until I noticed that I “plugged” it into the void in between the connectors. Now I’m always checking from different angles to make sure the connector is seated properly. The front view can be deceiving
I’m in the middle of a print right now, and wondering why the part fan isn’t on, and why I can’t turn it on manually. I’ll have to wait another hour before it’s done to see if I did the same thing. I swapped hotends about a week ago and only printed a couple of small parts since then. I thought the whole point of running a calibration afterward was to make sure everything was connected correctly.
Yup, it looked like it was plugged in, just like the OP said, but it was above the socket, sort of halfway in it. I’m glad I caught it before that print finished. I slowed it down with silent mode when it got to the quick part of the print, and turned the aux fan to 100%, and it turned out fine.
