Bug Description

Hi! Thanks for the great piece of sw, so far I have some problems with the virtual printer, specifically, I enable the Virtual printer, configure the ports and cer file and i'm able to print to the virtual printer. But when i try to connect back to the printer i get a connection error (possibly due to the wrong cer). This would be acceptable if there would be a way to edit the filaments in the AMS and perform calibrations from Bambuddy but there is no way to do it so the only way to perform such activities is to revert the cer and connect to the printer.

Install over ProxMox LXC (Debian)

Expected Behavior

Being able to connect to both printers would be a nice addition, or being able to edit AMS and Flow calibrations from Bambuddy.

Steps to Reproduce

1 Follow the Virtual Printer steps.
2 Connect Bambu Studio to Virtual Printer.
3 Connect Bambu Studio to P1S

Printer Model

P1S

Bambuddy Version

v0.1.6b9

Printer Firmware Version

01.09.01.00

Installation Method

Operating System

Per documentation you must replace the slicer cert. Perhaps this is OS specific. Please try by adding the cert to the end of file instead of replacing the last cert in file. So just add it.

Hi appending the cert to the bambu studio cert did the trick. Mac OS is the OS
