Is there an existing issue for this problem?

I have searched the existing issues

OrcaSlicer Version

OrcaSlicer 2.3.2-rc2

Operating System (OS)

Windows

OS Version

win 11

Additional system information

No response

Printer

klipper, mainsail version ,spoolman Creality Ender-3 V3 SE (multiple units, same model)

How to reproduce

Configure two or more printers of the same type/model (e.g., Ender-3 V3 SE) in OrcaSlicer.
Sync material on printer A.
Switch to printer B (same model) and sync material.
Observe that the material does not update unless you first switch to a printer of a different type/model (e.g., a Klipper-based printer) and then back to the second Ender-3 V3 SE.

Actual results

When switching directly between printers of the same type/model, OrcaSlicer keeps the material cache and does not force a material update or reconnection. The material only updates if I switch through a different printer type first.

Expected results

OrcaSlicer should force a material reload/sync and reconnection every time the printer is changed, even if they are of the same type/model.
