I just created this topic as I assume there will be need to discuss this new machine (2024)
The K3 can only be accessed by the Anycubic cloud - or by an USB-Stick. There is currently no option to use your local network. The cloud at the moment excludes all slicers but Anycubics own slicer, which - at the moment - is a clicky-funky fancy toy slicer for kids.
I like to have your (experts) comments on the following idea: Raspis can be run in OTP mode mimicking an USB stick. The OTP raspi could host OP. OP can place gcodes on the stick that it receives by local network. So it should be possible to pump gcodes into the K3 without sneaking into the printing room with USB-sticks.
Hello
Maybe this helps
