MK3S. Message: "press the button to unload the filament"
Hello
I just finished riding the MK3S.
All tests ok
Calibration test of the first layer ok (-250)
Launching a first print (Batman) and message "press the button to unload the filament"
Unloading, reloading ok. Relaunch of printing and same message
A new test calibration first layer: ok
Batman print restart: same message "press the button to unload the filament"
I tested with one of my stl very simple: the printer starts the calibration of the bed in 9 points, then the extruder returns in front, in the middle and same message as previously
Printer loaded with silver Prusa PLA
What to do please?
cordially
RE: MK3S. Message: "press the button to unload the filament"
In the Prusa Knowledgebase, I found this article that evokes exactly this problem
MK3S keeps prompting filament change
https://help.prusa3d.com/article/43mduc4zdn-ir-sensor-troubleshooting
I followed the advice (put off the automatic loading by keeping the sensor on)
They explain that at least we can use it like that before solving the problem
Before dismantling the extruder, I tried to see if it came from this mechanism.
Wire unloading and manual reloading
And there, blocking the wire in the nozzle!
So I'm following the step by step mentioned above and disassemble the extruder (say I spent half a day to mount it)
The problem is that I do not see how to remove this wire from there
I heated the nozzle up to 230 ° (fan on the way) and nothing, no way
Any idea ?
RE: MK3S. Message: "press the button to unload the filament"
Problem solved.
1) Disassembly of the nozzle and unblocking
2) The sensor remained at 0: it was a bad connection to the card (top row instead of bottom)
3) The sensor remained at 1: inserted a piece of cable gland (delivered with the kit) under the sensor board, on the wire side (towards the back)
The sensor works, autoloading too
