Alarm 2 in lightburn monport k40

LightBurn Software Questions
1

yesterday I started getting this alarm. I have tried changing settings in the book and still nothing. I cleared everything I know to clear, reinstalled lightburn and it still pops up. It will home and that is it. Hopefully i am just a dumb new user and its something i missed.
I have a monport k40

I meant the .lbrn2 file with a project that fails in it. Your last post is the GRBL parameters.

13

I dont know what you are looking for. every project fail now. It will not come off home for anything.

14

That is a different kind of problem. I was looking for the possibility of your part being at the edge of your workspace and overscan causing a problem.

It now sounds like you have a coordinate setting issue. If Home works, motion control is still working.

Enter these one at a time in the Console window. We already have $$:
$I
$#
$G
?

Now copy-paste the output in the Console window in your reply.

When a Forum member asks for you to do something, you should not worry about why unless they are asking for personal or proprietary info. If the reason does not become apparent by the time of the solution, they will explain their reasoning. We are here only to help, not judge. This is the most civil, and supportive, Forum I have ever seen, which is why I continue to participate.

By the way, welcome to the forum. You will learn a LOT here!

This shows your project completed at least 1 pass. Is this what you saw?

Something like this sometimes indicates a communications issue, like a bad USB cable. Bad communications can give you a whole batch of misleading symptoms, often appearing random. Do you have another USB cable you can swap in?

17

I was looking for the possibility of a workspace offset causing your problem.

18

have swapped the cable and still same. it homes and does nothing else. I think I either have a bad board or something in software is corrupt. I attempted using it with a different computer but I think it read the info off card and gave me the same alarm 2 code.It did not complete any passes I do appreciate your helping

19

have you done what i said and done it in absolute coordenates?
Next picture you sent was still in user origin
