I’m trying to implement an hardware joystick to move the laser head of my system.
An Arduino is reading and decoding the joystick analog values and convert them to moving instructions sent by UART to smothie board firmware.
I’m sending “$J” commands to move the head, and they work fine. What I’m not able to implement is the Jog Cancel command.
In GRBL documentation, in order to cancel immediately a jogging movement ($J=…) I need to send a Jog Cancel realtime command (0x85 ‘ASCII Realtime Command’).
Nevertheless, I’m not having success implementing the jog cancel.
Any advices in how can the jog cancel command be done?
Is there any documentation about the Jog commands ($J=…) available in Smothie?
