I have some issue like the following :
When I tried to control manually then got an error message “jog target exceeds machine travel. command ignored grbl gru”.
When I press “Yes” to exit program there was no response wit the grblgru, so that I need to reconnect my Arduino mega.
Sometimes show “alarm 2” and when I press “start homing” the Z-axis motor can’t stop running.
I know it’s a position problem and I tried to set all axis to zero but it still has an error.
I don’t know where it’s got wrong. Hope this problem can solve.
