Photon Mono X - Failed to open file



formware latest 1084
Printer Anycubic Photon Mono X
Imported profile on install, output PWMX
Firmware of the printer 3.4.8

FIle is sliced, saved to USB flash disk, printer sees the file, but no preview and when trying to load the file, printer shows error: Failed to open file!

Tried different USB flash disk and rename the file to shorter name.pwmx

Any idea what is wrong and what can I try?


Yes it’s most probably your printers firmware.

I think 3.4.8 was the old versino of the file.

(there are more topics discussing it)

kind regards
