The “problem” is that Luban does not really support multiple toolpaths, i.e. you cannot easily do a roughing pass with a larger bit to get away a lot of material quickly and then a second pass with the tiny V-carve bit to work out the details. The lion you refer to earlier is supposed to be milled into the epoxy material, and there the V-carve bit is able to eat away the soft material in one go, which makes the lion relatively fast. In wood, I’d doubt that the V-carve bit will be able to do that.
There is a guide by @Skreelink that coaxes a multi-path approach from Luban, but you need to do a few tricks. One problem is that Luban does not know rest machining, i.e. it does not remember what was already milled away in an earlier step.
Snapmaker themselves confirmed some limitations of Luban, i.e. not taking the milling bit dimensions fully info account (see this thread).
Long story short: The rotary module can do a lot (it will be slow, after all it is only 50W), but the software limits you. Unfortunately good 4-axis-CAM software is prohibitively expensive for hobbyists - DeskProto has a hobbyist’s license that is affordable, but has its own limitations, and with Fusion360 free edition, there at least seems to be a way to do indexed machining (never tried myself). If anyone has a good recommendation for affordable 4-axis CAM please let us know!
