Bug Description

As you can see in the screenshots the hotend infos in Bambuddy are not correct.
In my case slot 1 is empty and loaded. Bambuddy says it is slot6:

slot 6 must be slot 1
so all other slot must be +1 (1->2, 2->3, 3->4, 4->5, 5->6)

Expected Behavior

Steps to Reproduce

  1. Open Bambuddy Printer with H2C connected
  2. Compare hotend informations in Bambu Studio and Bambuddy

First of all you need to set up your system properly following the install docs! There are lots of errors in your logs. For example:

  • Developer mode is not enabled
  • There are folder permisson errors for your Docker mounts
  • Bad crendetials for MQTT broker
  • Spoolman is configured but not accessible
    [....]

At least developer mode needs to be enabled. We observed the crasiest errors when it's not enabled.


Regarding the nozzle issue:

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

Thanks for that.

I installed via: curl -fsSL https://raw.githubusercontent.com/maziggy/bambuddy/main/install/docker-install.sh -o docker-install.sh && chmod +x docker-install.sh && ./docker-install.sh

so i dont know why there're folder permission errors.
The rest is known and will be fixed.

Depends on your Docker host environment. Just check logs for "permisson denied". It also gives you a hint how to fix.
