I've got an 3018 chinese cnc.
I connected it to my windows 10 PC with arduino ide / Grblctrl and I can connect to the device via USB /serial (USB-CH340 controller).
I get the message "Grbl 1.1f ['$' for help]" when I start IDE / Grblctrl
After that nothing: I can't give any command to Grbl. $, $$, ? they don't produce any output.
Any idea how to fix this?
Thanks in advance.
