I continue to have problems with this machine. It seems when I replace a part, another error comes up. I have replaced the TH board, Duel extruder unit, quick change tool interface, toolhead front cover, duel extruder filament guide, extruder connection board, and the right hall sensor. I am now getting the error about the motor on the rack and the above parts did not fix the original problem. I cannot calibrate the machine as it says there is no extruder in the right placement when the extruder is there. I cannot factory restart as it is not detecting the nozzle in the right extruder. It will not read the nozzle information. I have placed new nozzles in it but the machine continues to ignore the extruder. I have inspected and cleaned and there is no debris, filament, or anything else that would cause problems. I can heat the nozzle and manually put filament in the right extruder and it will melt, but still it will not recognize the right nozzle. Due to not recognizing the nozzle the vortex system on the side crashes because the nozzle will not change. I f take the nozzle out it says ‘unrecognizable ‘ otherwise is says “empty’. I cannot manually change it to the nozzle on the print screen and cannot do a read all as it crashes. Any help would be appreciated, I have had the machine since January 2026. Than you.
The wiki contains extensive guides to hotend issues , there is also a hms wiki to look up the error codes ??? you may also want to look at the H2c course
I have extensively researched this on Google, wiki, reddit, h2c, and support. I am out of thoughts on this as I have been working on this for a month. If you have any specific recommendations I would appreciate the help.
Introduction to the Workflow of the Vortek Induction Hotend | Bambu Lab Wiki
Induction Communication Board: Transmits information (including hotend temperature data and printed filament information) with the receiving board of the induction heating assembly in a non-contact manner.
This is the 5th guide in the H2c wiki ,
I have replaced this as that is what I originally thought, I contacted support and bought one. Still having the same problem, but thans, I appreciate it.
I would suggest opening a new ticket ,uploading log files and hms errors .
Safe and Reliable: Hotend in-position detection ensures that only properly installed hotends can be activated.
i would probably add correct Bambu lab hf/nozzle ,
