I already have a fully functional Spoolman server running on my Unraid server, with my K1 and E3v2 setup to use the Spoolman integration. I picked up an HI Combo yesterday and tried to add the Spoolman info to the moonraker.conf file, but when the printer resets, it throws an error for Spoolman. The Spoolman config in moonraker is identical to the other printers.
I’m on the same boat as you, it seems that the shipped moonraker in the creality hi is not updated and so, moonraker does not have the spoolman module it needs, same thing happens to fluiid, thats why you cant activate update_manager either… this needs to be updated by creality for us to use…
