I have been using the slicer to produce gode files, and then transferring them to the SD ard and printing successfully. Now the printer sees the gcode files as present, but thinks they are empty Older files on the same SD card are still read ok, and print ok. Has something changed in the slicer ?
I’ve tried reinstalling the slicer, same result - the PC sees the file as being the expected size, the printer sees the file is there but thinks it is empty. I’ve tried deleting an old file and copying it back onto the SD card - that shows ok, so the PC is writing to the SD card ok. So it looks like a problem with what the Slicer is producing.
