I’m having an issue here where if I’m doing something close to the sides, and I have overscan selected, I don’t get a warning that the job is out of bounds. If the design itself is out of bounds, I get the warning. But if the overscan will take it out of bounds, no warning, and it will start the job with the expected consequences.
So I did a quick test, solid circle in fill mode, ring round it in line mode. I moved it such that the outer ring was off the page, went to preview it and I got the expected warning.
When I chose Yes, the preview looked like this.
So the outer ring is missing, as expected, but you can see that the head movement is grossing the green line on the left.
So, is there a setting somewhere to enable this warning?
Recent experience with my machine does not show this behavior. In fact, I reduced overscan to stop the alarm. Are you sure it is actually going out of bounds?
I’m getting the same thing with my new Algo DIY on 1.4.05 and the warning works fine on my Ikier using the same PC. I feel like an idiot. Sure I missed a setting somewhere.
Your work size is correctly configured in Edit->Device Settings. If you have changed the laser module from the factory default the work size may need to be adjusted to accommodate the new module
The machine is homing properly and that position after homing is correct for your laser
No moving of the laser head by hand. Use jogging controls exclusively.
“Enable ‘Out of Bounds’ warning” is enabled
These things alone should get you proper out of bounds warning. If any of these are not true then out of bounds warning will fail in some situations.
Additionally, these things can simplify troubleshooting or avoid other similar issues:
Work in Absolute Coords. Out of bounds situations while using User Origin or Current Position can be non-obvious
Make sure max travel dimensions are configured properly in GRBL machines ($130, $131).
Right, well this is weird. I just tried it again, and I did get a warning this time. It’s strange that the warning only appears when you attempt to start the burn, rather than previewing it, but I did indeed get the warning. And if you’re paying attention, the preview will show the movement crossing the boundary, so it shouldn’t get to the point where you’re starting it.
I can only assume that the time recently when my laser head crashed into the side rail while overscanning was due to me setting the starting position by hand, which I rarely do.
