GRBL-LPC get Alarm9

Board Configuration and Setup
#1

Machine: _K40 Blue/white W40

Board: _C3D laser board

Firmware: GRBL-LPC

Problem: Can not send lasers home That sounds strange. It’s jumping teeth.
And I get this on Console:

ALARM:9
ok
Grbl 1.1f [’$’ for help]
[MSG:’$H’|’$X’ to unlock]
[MSG:Caution: Unlocked]
ok

I just download:
SpreadCycle version: firmware_grbl-lpc_c3dlaserboard_4axis_spreadcycle.bin
And put together with (config.txt) from Smoothie one.

Any suggestion?

We will resolve your issue in the other thread, by controlling one variable at a time, starting on the Smoothie firmware.
