A couple questions:
- What settings did you use for the image? (DPI, image mode)
- Do you have other files in the memory of your machine?
- How are you connected to the controller?
- Are you using ‘Start’ or ‘Send’ to transfer the file?
LightBurn should tell you the size of the file when the transfer is running. If it’s larger than 100Mb it won’t likely fit. If you have files stored on the controller they’ll take space away from that number, so clearing them out can help.
If you use a wireless connection to send to the controller, that will also be a problem - WiFi isn’t reliable, and Ruida’s connection method doesn’t allow for errors, so it just gives up if a packet gets dropped. Using a cable between the PC and the controller (or through a router or switch) will solve that.
