I jog the laser out to the beginning of the job and use the “User coordinates” after I set the origin.
The job executes great. After the job the laser head runs to the right and crashes until I turn it off and it re-homes.
Any ideas how to fix this?
What I have been doing is setting a “Finish position” for the laser and while that works, I feel like there is something else bigger picture that I am missing. Im afraid if I forget to set the “Finish position” ill have a mess on my hands.
running to the right and crashing seems super off… Machine configuration at fault ?
I would guess because you are setting your zero on the rotary, after the cut is finished it is returning home or another coordinate but your soft limits think they still have longer ways to travel. Bang! overshooting the physical limits. You could possibly try setting those limits shorter to offset the rotary. So the laser will trigger a soft limit before it crashes.
Thanks for the reply. Maybe I do need to check the machine settings, but home is to the left, not the right.
There is no limit switch on the right. It is only on the left.
When I turn it on and it “Auto-homes” it auto homes to the left properly and stops on limit switch contact. that is why I am a bit confused.
I would try that first. If you can post your GRBL settings here, there are some super smart folks in the forum that may spot potential problems with your configuration. Type " $$ " into the console window and post the result.
You may have an offset programmed or just the x.y 0 is set incorrectly. You will want to update your machine settings. When you are next in front of the machine take a moment to screenshot your GRBL settings. Please go the the console window in Lightburn and type $$ to display the current settings. Take a screenshot or copy and paste that here.
