Front Cover of Tool Holder Fell Off Message

Bambu Lab X1 Series Troubleshooting
1

At this point the printer is not able to do any useful work. I reseated the connector the cover is snug. I can’t see any reason for the Hall Effect sensor to not sense the magnet. I created a trouble ticket and attached the exported log files. Is there a way of bypassing the sensor? Is there some additional remedy that has worked for others?

BTW, even though I got an email about the ticket being updated, I can’t find the ticket in the system it is udc:001d22ae if I read the notice correctly

After trying to figure this out for about two weeks, I found a posting by Technique on Discord saying that he was unable to fix the problem with repairs, but Bambu sent him one line of G-Code to insert that then bypasses the missing toolhead check. I applied this code and it works perfectly.

  1. Open Bambu Studio and click on the Printer “Edit Preset” iconto the right of your selected nozzle.This will open a new “Printer Settings” dialogue box.
  2. Select the “Machine G-Code” tab in the dialogue box that opened in step 1.
  3. In the section titled: “Machine start G-code”, add the following line immediately below the existing line that says “;==== reset machine status =====”

This is the line to add:
M630 S0 P0

Then click on the Save Icon and save this as a copy of your printer settings.

This worked for me. I hope it helps someone else who is having the Toolhead fell off error.

Thanks

Thank you for sharing this! I have a ticket open for false alerts about this, and it looks like they’ll be sending a board for me to replace, but I’d like to be able to use my printer without these false warnings coming up 2-3 times at the start of every job.

Let me know if you had any trouble editing the G-Code. Strangely enough, I have changed out basically all the head parts (boards etc…), and it did not appear to fix the problem. But then, when I tried to re-create the problem using the non-edited G-Code, it worked again, and continues to work fine so far.

Good Luck - Just reach out of you need any help editing the G-Code

I haven’t received the replacement board set yet, but this code did stop the errors from happening. However, as you’ve mentioned, I’m not getting the errors now even using the unmodified G-code. I suspect that this G-code entry is basically flipping a toggle in the printer settings that stays set until you flip it back. Now I’m wondering what the command to revert it to the original setting would be.
I’m searching online for an explanation of what the M630 command is, but haven’t come across it yet.

Thank you, thank you, thank you! Didn’t work at first but after a reboot, she is printing again!
