Show last position

OK, when I click on “show last position” the indicator icon is completely off the grid area, when it should be exactly in the middle of the grid?

What kind of controller / firmware is “DIY”?


Assuming GRBL, you likely have a workspace offset programmed, but have the system reporting in machine (absolute) space, not workspace. Depending on the GRBL version, you change this with the $10 setting. For GRBL 1.1f, it’s $10=0 to report in workspace. For GRBL 0.9, it’s $10=2 (I think…)

OK, using keyes controller, grbl 1.1, have tried everything to correct the position of the laser on the workspace, so far hasn’t worked. Am attaching a diagram of my problem, thanks for your help.

“I have tried everything” - it would be more helpful if you could tell me the details of what you’ve tried, so we can eliminate those.

In the console, type $# and press enter, and post the response from the controller here. Then, type $$ in the console, and post that too.

If you normally use your machine as a CNC, it’s common for them to use workspace offsets that change. In LightBurn, you usually set the origin to the front-left by jogging there and zeroing, then set the controller to report its position relative to that point.

Does your machine have homing / limit switches?

Have limit switches, not homing, here are my settings, note $10=3 is the last setting I tried.

Based on the official documentation for your firmware:

This was pointed out above.
