I need help (see my attached image).
Here is what I did.
1. Home the machine.
2. Load the .ngc file ( The graphical tool path shown in the attached image, file generated by Fusion 360)
3. Click on Touch off button to Zero X and Y (No change, no matter what coordinate system was used)
4. Click the play button (got the error X exceed the limit). It was fine the day before with the same .ngc when Zero not show negative value in the preview)
Thank you!

The image is missing but judging from your description it seems that you are not doing the touch off at the right position. The way you describe it the work coordinate zero is at the machine home position, are you sure that is what you want?

thanks, reattached the image. The touch off is at the front left corner right after homing.

Yes, that is what I want. I am making the wasteboard and this operation is to create the threaded inserts which have some margin around them which is fine.

You have negative values for X axis, or the gcode contains negative value for X, at the end as it seems.

Tommylight, Is it possible if you can load the attached .ngc to your LinuxCNC?
