Neje Master 2S Grbl cannot guarantee position. Lost steps are likely. Re-homing is highly recommended

Hi!
I am trying to laser my project. If I push a button to set laser in to go to the spot on working area positioning seems to match perfecly. If I push burn project it goes into wrong spot usually like 10cm lower from working area and starts burning. If I reposition the work under laser again it goes lower and lower etc…
I tried press homing it but it didn’t help.
Neje Master 2S Max should have X are 810 and Y 480 so it seems I’ve set correcly. Homing laser didn’t help.

Reset while in motion. Grbl cannot guarantee position. Lost steps are likely. Re-homing is highly recommended.

How to overcome this I can’t continue my project…
I should have no electric noise issue I’ve read on some forums it might be for a laser not to function properly.

This strikes me as being the key to unlock the problem.

Some of these numbers are fairly… unorthodox?

I’ve set start point to absolute coordinate that seems to work!

Hola,

Yo tuve un problema similar, lo solucione reinstalando el gbrl nuevamente.
Primero averiguar qué versión de placa tienes, hay como mínimo que yo sepa dos.
Luego en la wiki de Neje encontrarás la posibilidad de instalar el grbl según la versión de placa que tienes.

Saludos,

Hello,

I had a similar problem, I fixed it by reinstalling gbrl again.
First find out what version of board you have, there are at least two that I know of.
Then in the Neje wiki you will find the possibility to install grbl according to the board version you have.

Greetings,

In the interests of clarity, i’d like to confirm that you are recommending a firmware update on a Neje not a LightBurn Setting or update.

Do you have a link to the Neje firmware updates?

Hola,
Aquí encontrás información útil, entre ella el firmware para instalar.
