Lightburn with the Neje Master 2S Max

[LAHobbyGuy]

Rich,
I don't think that's possible with this laser. The controls, limit switches, etc are all on one component on the left. There is nothing to switch from back to front.

I emailed my contact at Neje engineering and he said my directions were correct. He said to point you to this Wiki.
If you follow my instructions and try and clear your head of all the expert advice you've gotten so far and what you think might happen and just try my solution, you'll get the machine to work properly. It doesn't matter what anyone tells you, when you have a clear symptom and that symptom has a solution across all types of machines regardless of manufacturer, you should use it. The directions I gave you were symptom specific, not manufacturer or model, and if you follow them, you'll resolve the problem.

Here's an excerpt from the Neje Wiki:

I really can't spend any more time on this very simple problem. You asked for help with a problem, I gave you the solution, and I even went a step further and got an engineer involved at Neje to confirm my solution, and that's the best I can do.

Rich,
I promise I'm not trying to be difficult. I just don't see a way to take take it apart and put it back together any other way. I will change my origin in the software to Front, Left as pointed out, and work from there.

Like everyone else here, I appreciate the time you take to help.

You don't have to take anything apart, just follow the directions I posted.

Uggh. I completely misread your post.

While it isn't "perfect" like the Ortur on Lightburn, it is acceptable.

This is what I did:

In device settings, changed the Origin to bottom left (as Rich suggested.)
In machine settings, Y Step pin invert: False, Y Direction pin invert: True, Y Homing direction invert: False.

I have to manually move laser to bottom left before plugging in/powering on.
Origin is bottom left. Home is top left.

Issue: Y Axis appears to go to bottom left 0,0 and tries to extend past this coordinate. Can’t see what I have missed from the posts on your site.

I have noticet that even after following below, when I select Home, the laser will go to the top left corner and the coordinates in ‘Move’ tab
Are showing X: 0.00 Y 460.00 Z: 0.00

I would have expected (after watching your Origins video that the Y value should be Y: 0.00 not 460:00


So Far:
Created a single horizontal short line in Lightburn - to burn to a sloping piece of ply (to gauge the best focus) Now I am sure there is a better way - but today is day 1 of my introduction to both CNC and Lasers

Watched your extremely helpful video on Understanding Origins, Absolute coordinates and Settings.
Read way too many ‘expert’ posts (not on your site), but found this to be the most informative and reliable……

Made the following changes:
In Device Settings - changed the Origin to ‘Bottom Left’

Also saw in a posting by micallen - and checked these values in the Edit, Machine Settings, Output setup:
Not quite sure whether I have to turn the Neje off and manually move the last to 0,0

Y Step pin invert ($2) = False (was already set)
Y Direction pin invert ($3) = True (was already set)
Y Homing direction invert ($23) = False (was already set)

Also checked S-Value Max value = 1000

I have tried setting the job origin….. to other than top right….. I suspect that I am missing something here regarding ‘set origin or move from machine zero’ but that’s an un-educated guess.

Any help appreciated……. I will definitely watch your other videos…and read posts by other members.

Turn the machine off and manually move the gantry to 0/0. Turn it back on and hit home and see what happens.

I too have the Master 2S Max from Neje. I'm just writing to confirm the limit switches, and homing, are to the top left of the frame, when viewed from the front. After the machine homes, the laser head is sitting at approximately machine position X0 Y460.

When you move to X0 Y0, the laser moves to the bottom left of the print area. I can jog correctly in any direction.

Yep, same as mine

Rich. Thank you for your reply.

I did as you mentioned and when I hit Home it goes to top left no issues but still shows cordinates X0:00 Y460.0.... when I tell it to go to X:0.00 Y0:00 (using the move menu) it goes to the bottom left and shows coordinates 0:00 0:00

So I have a string of text in the LB workspace and when I say Frame the laser head goes to the right area on the workspce but when I say Start the laser head goes to 0:00 0:00 bottom left and tries to extend past this coordinate.

I'm still not sure what I am doing incorrectly.
Not sure if this help, bu tI saved the Gcode output of the straight line and here it is. As mentioned before if I do a Frame the laser head goes where I expecrt it to, but when I tell it to atart it goes to and tries to pass the origin 0:00, 0:00 Bottom left
