There has been no indication that Bambu is preventing rollback to the rootable v1.06.
Network options (from the X1Plus Wiki):
- Network: Bambu Cloud
- Printer has full access to the internet + bambu cloud. All outbound connections are allowed.
- Network: LAN
- Printer connections are restricted to LAN by software-based permission checks performed internally within the firmware.
- Network: LAN + shield
- An enhancement to LAN mode that uses Linux iptables to block outbound connections from the printer. Outbound UDP (for example, DNS, NTP and SSDP) and outbound ICMP are not blocked. The purpose behind this enhancement is to block outbound connections at the OS level, so even software bugs or malware would not be able to establish outbound connections.
I think the “software-based permission checks” refer to the current Bambu network plugin.
The LAN+shield option is beyond my understanding. I think it prevents the printer’s operating system from spreading malware?
