Get this error every time Laser is homed:

ALARM:9

Homing fail. Could not find limit switch within search distance. Defined as 1.5 * max_travel on search and 5 * pulloff on locate phases.

Interesting thing id the laser is homed and ready to cut. It is at 0,0 and cuts fine.
Just wondering if I need to worry about the Alarm 9 or if it is a ghost?

I assume you have homing switches.
Is it homing normally by hitting the switches and pulling off?

3

Yes, However they are mounted in a fixed configuration on this laser and I’m thinking about replacing them with the one of my old laser that where adgustable
Or at least the Y axis one

4

What do you plan to gain from this? If the current switch is electrically correct, there is no reason to replace it.

5

the ability to adjust the y axis limit switch and thus hopefully end the Alarm

6

This is not a switch position issue. If it finds the switch and pulls off, it is a mechanical problem corrected with a GRBL parameter setting.

Increase the $27 parameter to $27=3 because 1.0mm is likely not enough.
