is there any way to put groundcontrol into a mode where it outputs (debug log?) what it would do but actually doesnt do/execute it?
I am getting tired if running my router-clamp-sled into the head of my Z-Axis. I would like to only check what it would do without the software actually doing/executing it.
Yes! What you are looking for is actually in the firmware. By setting the firmware
// Define global flag for FAKE_SERVO state
int FAKE_SERVO_STATE = 1;
In line 50 of cnc_ctrl_v1.ino you can set up exactly that behavior. The machine will pretend it is moving and everything will respond normally except that the motors will not move.
