Good morning everyone,
I have a P1S, and for the past few weeks I’ve been getting the error HMS_0700-4500-0002-0003: “The filament cutter handle has not been released. The handle or blade may be jammed, or there could be an issue with the filament sensor connection.”
I’ve checked the printer and followed the advice on the wiki, but I can’t seem to spot anything unusual, so I contacted support and they suggested I replace the extruder filament sensor.
Despite this, the printer is still displaying exactly the same problem, so I also replaced the filament cutter blade and the extruder, just to be sure: the printer powered on correctly, performed axis homing, extruded filament correctly, printed the purge line on the front of the bed, calibrated the bed and then… it froze again, displaying the same error and making any operation impossible, including unloading the filament.
I can confirm that the blade is working fine: when moved by hand, it feels perfectly normal and moves without any issues.
Now Bambulab is suggesting replacing the entire extruder circuit board, but given that all these spare parts are starting to add up to a significant outlay… has anyone else experienced this and can offer any advice?
Many thanks in advance
