Hello i want to make 3d printer (cherry 3d) with cnc shield but when i want to load code, i take error: board_ramps_14_efb what i need to write?
Why would you want to use a CNC shield? It has no hardware to drive the extruder or bed heater or inputs for the thermistors. Sure, you could hack those features onto the shield, but a RAMPS board does all that for you. As for your error, I think you will need to provide more information, like what Arduino board you are using, version of firmware, etc...
USE RAMPS instead of using CNC shield, CNC is a thermistors device that provides heat which may damage your system... if still have an issue contact Fix HP Printer Error code messages
