I have a BB Dual Hybrid with titan extruders took sd card out. changed the name from 3dbenchy to benchy LCD still says NO SD CARD if i put the card in a use the LCD to find the file on the SD card and push the knob... nothing happens. If I load the same file in Octoprint it loads.. if I print from Octoprint, the printer goes through the motions like it should be printing but does not extruded. If i go under control tab in Octoprint and select tool the extruder functions. Both of them. Can anyone help?
