Issues sending prints/possible connection issues:
I am having lots of issues with sending prints to my printer from the queue, I have had two main scenarios.
-Sometimes as soon as I send a print and click clear plate, the progress will go to 100% and sit there. I can cancel it and try to restart with no luck. Usually restarting the printer and docker container will fix this.
-Second issue, looking at the logs it appears I should be getting a "clear plate" option to start the print but it is not showing up and the print is stuck at "printing 0%". Unless I am mistaken, this should only go to "printing" after clear plate is clicked.
Other related symptoms I have:
-Intermittent connection issues to the printer with bambustudio when also using bambuddy.
-The manual controls for the light do nothing, but when using my panda touch it works, so there is connection to the printer on the network.
-I often get a failed to read/write error to sd card. I have had this before and have replaced the card multiple times, possibly just a coincidence, does not always show when my main connection issue is present.

I've (still) the same/similar issue. I'm on v0.2.3.b3. Docker on Linux/Ubuntu. Send file (.gcode.3mf; 3 plates; 1 selected) to queue. "Clear plate & start next" shows up for the printer. click on it. seems like it starts printing, but nothing happened. Then it shows up in Queue under "Currently printing" with 100%. Printer is doing nothing. How can I help you to fix this? And what would be a workaround? Thanks

Almost certainly hitting the task_id int32 overflow — project_file command gets accepted (result: success) but the printer treats every dispatch as a continuation of the prior task because your task_id is "0" (v0.2.2.2) or a 13-digit epoch-millisecond number that firmware clamps to 2147483647 (v0.2.3). See #1042 for the full root-cause analysis. Fix merged in d0f35e5d on the dev branch (caps task_id at 2**31 - 1).

Available/Fixed in branch dev and available with the next release or daily build. Please let me know if it works for you now.
