Feature:

1. Offline Control: With the offline controller module, you can control the CNC router without connecting to a computer, so the CNC router can be placed anywhere you want, such as garages and workshops.
2. Manual Control: The XYZ axes position can be manually adjusted as the starting point for engraving. The module can also manually control the spindle on or off mode.
3. Simpler Access: After the file is put into the memory card, the engraving file can be directly recognized. You can also connect the offline module to a computer via a micro USB cable and store files directly.
4. Ideal Matching: The offline module is perfectly compatible with 3018, 3018 PRO CNC routers and other general purpose 3018PRO CNC routers.
5. Easier Working: You just need to connect the offline module to the GRBL controller board and then you can use this module to control the CNC router.
