Qidi

I recently acquired a Qidi X-Plus 3d printer.

Slicer

I'm using QidiPrint on Linux via its AppImage distribution. It appears to be a customized version of Cura, and comes with preloaded configurations for the full Qidi line. There was a Cura 4.x plugin that went by the same name, but it doesn't seem to work with Cura 5 (or even newer versions of Cura 4).

Networking

The discovery protocol used by QidiPrint involves broadcasting to an attached IPv4 network on udp/3000. A Qidi printer will respond from source port 3000 to some random on the broadcasting host. To do so, configure QidiPrint with the host's IP address on the relevant network, press "Apply", and then press "Refresh". The printer ought show up. Note that since the outgoing query went to the broadcast address, there will not be an existing connection, and local firewalling is likely to require a specific rule based off the source address and port (together with UDP).
