Neje master 2s / axes deplacement

LightBurn Hardware Compatibility NEJE
1

Problème au lancement d’une découpe, j’ai le message svt “coupe en dehors des limites”
Uploading: image.png…
Uploading: coupe-hors-limites.JPG…
et si je lance malgré le message la tête laser se déplace est vient buter dans le rail.
complément d’info.: ma neje master 2s a été trouvé et lightburn indique bien sa bonne taille 810 * 460 mm.
Je suppose un problème de sens des axes mais je ne sais pas comment faire pour changer cela, merci pour toutes les info. à venir.

In Device Settings make sure Origin is set to bottom-left.

Is this your laser?

If so, area should be 255x420. Make sure this is set in Device Settings.

  1. Use Absolute Coords for Start from mode in Laser window
  2. Make sure the machine is homing correctly when started
  3. Never move the laser head by hand after homing. Only use jogging controls in Move window or keyboard shortcuts.

L’image ne correspond pas à ma neje master 2s, mon espace de découpe est bien de 810 * 460 mm comme l’a détecté lightburn.

Au sujet des conseils ci-dessous:

  1. Use Absolute Coords for Start from mode in Laser window* OK
  2. Make sure the machine is homing correctly when started* OK
  3. Never move the laser head by hand after homing. Only use jogging controls in Move window or keyboard shortcuts.* OK

Résultat: toujours le même problème si je démarre une découpe ( même message) + tête qui va dans le rail.

Can you provide a link to your specific machine? I’d like to confirm what it looks like and the dimensions.

Is this perhaps your laser? It is Neje Master 2s Max model.

Also, can you home your laser and then run each command in Console window and return output:

$I
$$
$#
?

Oui c’est ma machine 810*460 mm.

Est ce que cela permet de déduire le problème ? merci par avance

I suspect this is your problem. This is creating a work offset which is making your controller think that you have gone beyond the boundaries of the laser.

Let’s remove it.

Please enter this in Console:

G10 L2 P1 X0 Y0

Then rehome and test your laser.

La commande ci-dessous ne règle pas le problème, j’ai essayé cette commande avec les 4 possibilités d’origine de lightburn.

G10 L2 P1 X0 Y0

Quand je lance la commande recadrer dans “laser”, la tête tape dans le rail sur l’axe longitudinal.

Merci pour une autre idée !

Can you rerun these commands in Console? I want to make sure things were applied correctly.

$#
?

Also, can you take a full screenshot of LightBurn please?

Nota: je suis en origine lightburn haut droit.

Maintenant ca marche, je te remercie beaucoup, je vais voir si en arrêtant lightburn et en l’allumant à nouveau si les paramètres ont bien été conservés.
:clap:

11

après arrêt et redémarrage LIGHTBURN c’est toujours ok, merci encore BERAINLB.
:+1:

12

Okay. Excellent. I expected that to work and was concerned when you said it didn’t.

Enjoy the laser.

Bonjour Berainlb,

Suite aux informations que tu m’a donné, j’aimerais comprendre le pourquoi des commandes à mettre dans la console.

Certaines sont compréhensibles mais d’autres le sont moins, aurait tu un document qui explique la liste des commandes possibles que l’on peut taper dans la console?

Merci par avance.

14

There are many online resources for that.

I suggest you start here:
grbl/commands.md at master · gnea/grbl · GitHub
grbl/settings.md at master · gnea/grbl · GitHub
