I don't know how how to generate support files from the bambuddy, can't find system information section but i will add some info to the comments.

Steps to Reproduce:
So nothing superordinary i just uploaded sliced 3mf file to the bambuddy and put it to schedule to start print after previous print will be finished, but i think this is where issue started, i checked this checkbox "Only start if previous print succeeded" but after previous print ended queued print didn't start, so i deleted this schedule and added print to the schedule again with unchecked checkbox and only after that it send it to print. And after this print ended it now tries to start this print every time i turn it on.

Printer: A1

Bambuddy Version: v0.2.3.2

Printer Firmware Version: 01.07.02.00

Installation Method: Docker

OS: Windows

You can see in log where it sends file to print:

2026-05-02 11:17:06,848 DEBUG [backend.app.services.bambu_mqtt] [[SERIAL]] gcode_state: IDLE -> IDLE, file: @SolomonHaki_A1v2.3mf, subtask: _SolomonHaki_A1v2

First of all I would strongly suggest to use Netwrk mode host - as per the docs!

I added a troubleshooting note for this exact pattern so other users hit it too: Printer Looks Like It's Trying to Re-Start the Last Print After Power-On.

Short version of why this isn't Bambuddy: your Bambu firmware keeps the last gcode_file / subtask_name in its MQTT status payload forever after a print finishes — those fields are still there on every power-on, even when idle. The touchscreen displays them too. Bambuddy only acts on a real state transition (IDLE → PREPARE/RUNNING), and your log doesn't show one for SolomonHaki after you deleted the queue item on 2026-04-28.

The thing your log does show on every power-on is 0500_C010 — the Bambu HMS code for MicroSD card read/write exception. That's almost certainly what's keeping the touchscreen in a "last print is staged" state.

Try this in order — most cases get fixed at step 1 or 2:

Reseat the card. Power off, pop the MicroSD out, blow the slot, reinsert firmly. Power on.
Format the card. FAT32, on a PC. The stock Bambu cards in particular fail like this.
Swap to a fresh Class 10 / SDHC card.
If 0500_C010 still appears after all three: contact Bambu Lab Support (bambulab.com/support → My Devices → A1 → Open Ticket). At that point it's the SD slot / mainboard or firmware corruption — not something a user can fix. Give them the HMS code, your printer serial, and a short video of the boot screen.
