Machine goes in oposite direction on Start

LightBurn Software Questions

Every time I try to run something it rams into the limit switches moving to the left on the x axis and table moving towards the back on the Y axis.

Here is the gcode perhaps you can help me figure out my problem.

Thanks,
George

You have a large world coordinate offset programmed, but $10 is set to 115, not zero. I also see ‘error:9’ which means your machine is set to home, but you don’t have homing enabled, and likely don’t have limit switches.

Your profile says you have a 3018, so start here and report back if you’re still having trouble:

3

To confirm my 3018 comes with limit switches. I finally got it to work G92 X0 Y0 and $10=0
I’m confused since the machine has limit switches and Homing is enabled.
I turned everything OFF and ON again and now it start from Homing, except that after its done and back to home, I have to reset and home it again before it goes to Ready. And lastly, I’m getting burned spots on corners which I didn’t have before.

4

Have you enabled Laser Mode? ($32=1) That should deal with the burnt corners.

You’re saying at the end of a job it has to be reset? or before you start one?

Literally stumbled on this post looking for help on a similar issue, The $10=0 code solved my issue!! Thank you! When I homed my machine it always thought it was in position X -10 Y -19. Every time I tried to move to 0,0 it would wreck my machine tryin to go in the wrong direction.

Hi Mike - We have this in our documentation if you look for ‘X-carve’: https://github.com/LightBurnSoftware/Documentation/blob/master/CommonGrblSetups.md#common-grbl-setups

It mentions every setting that needs to be changed, including the $10 setting. (probably doesn’t help you now, but it does explain why they’re needed)

7

Yes at the end of a job it has to be reset and homed and than it goes to ready to run again otherwise it gets stuck on the green process/status bar at 100%

8

Are you getting ‘Alarm 1’ at the end of a job?

That’s ‘hard limit triggered’ - hitting the limit switches, which would make it so you had to reset the machine or at least the connection. You could try setting your ‘Finish Position’ to a little away from 0,0, or turning off ‘Return to Finish Position’, in the Device Settings:

Okay, I just rand it and it goest home after it’s done and it is triggering a limit switch.

10

You hit it right on the nail…
I set it to return to x:10 and y:5 after finish and that dit it! No more resetting.
Thanks for your Excelente support!!!
