Limit switches work for homing but don't work otherwise

X-Carve Troubleshooting
1

I have limit switching, and when I home the x-carve they work as they should. but when carving if for any reason easel or the g-code gives command to move beyond the limit switches the x-carves bumps them, and keep pushing against them, until I use the emergency kill switch.

What is the problem?

Search is your friend, start here …

Basically, they’re homing switches, enter the machine size in GRBL and enable soft limits to prevent smashing the end stops.

Thanks Phil. This whole issue is confusing to those of us unfamiliar/uncomfortable tinkering with GRBL/etc.

sounds logical, I’ll try that.
A bit overwhelming for new people to CNC, lots of new things.

David, I have the same issue as as the original poster. Could you elaborate on Soft limits.
$20=1?
I know how to get to the machine inspector, do i need to ensure this value is set like what you posted?

x carve has homing switches. you can set soft limits, so if it homes then it knows how far it can move before striking the end.
$20=1 ; turns soft limits on.
$130= (x max travel)
$131= (y max travel)
$132= (z max travel)
