Neje max 4 lightburn control Y axis problems

Hello all

I have a NEJE max 4 laser with the extension of the size (1030x750mm).

In the original program of Neje I can control the laser without problems and send it to the right position.

In Lightburn the X axis works without problems but the Y axis does strange things.
For example, if I move my drawing +400 mm down in the Y axis, it does not go down but the laser goes up into the wall/mount or somewhere else.

The home button works without problems and it goes where it needs to.
But somehow it has problems with the Y axis…

When I laser a square, it has the correct size.
So the Y axis steps from the motor are correct.

Does anyone know this problem?

Thank you very much and best regards

  1. Confirm that the Origin setting in Edit->Device Settings is set to bottom-left.
  2. Can you confirm if jogging controls work correctly in Move window? Up moves up, down moves down, left moves left, right moves right?

Yes, I confirm that the setting is to the bottom left.

The movements: Up moves up, down moves down, left moves left, right moves right work via the arrows without problems

Ah, I have found the error.

I need modify the lightburn software GRBL parameters $130 $131

Thanks for the help and best regards
