Home and directions misaligned

LightBurn Software Questions
1

Hello all

I’m using a Jtech laser on my shapeoko 3xxl. I have lightburn 1.0.6. Everything use to work perfectly out of the box without making any settings changes but now it doesnt.

Lightburn will home my laser to the top right where the limit switches are with no issues.

The problem now is that when i try to move the laser down and left in the software it tries to move the laser physically up and right.

I have tried reverting to lightburn 1.0.4, uninstalling and reinstalling 1.0.6. I have tried the offset macro (…x-845 y-845) and one to reset it to 0,0. I have tried a different computer, i have power cycled all devices. I removed and manually added my shapeoko. When removing and re-adding i changed the home from top right to bottom left. I need to get some projects done asap.

I have an email into support but thought id ask here too. Thanks!

Lightburn - EDIT > Machine Settings > (scroll to bottom) Vendor settings > X or Y

Keying direction - XXXXXXX (changes the direction of the head movement)

So changing the directions in the x and y didn’t do anything so i reverted back to defaults. I was able to make it so pressing down moves the laser down however this is the issue. Again my laser/machine homes to the top right and the program thinks the top right is bottom left. Even if i change the origin in the device settings it still does this. I was able to run the program out of bounds but if i save the location and go to that its way off. Attached shows where the the program thinks the laser is vs where it actually is.

This sounds still like some sort off offset issue.

What is the reported position after homing?

Can you run these commands in Console and report back:

$I
$$
$#
?

Thanks for any help!!!

Are these your actual dimensions for the working area? I’ll go ahead with these but if they’re not you’ll need to make adjustments.

You’ve got this incredibly large offset which is probably why things are acting funky.

Try this:

G10 L2 P1 X-845 Y-850

If X and Y are incorrect you’ll need to adjust $130 and $131 and then also put those numbers into the command above.

i have used G10 L2 P1 X-845 Y-850 and it says ok when done. the problem is when i move the laser it still is trying to think that the workspace is outside of the boundry of whats listed as in my last screenshot. regardless of where i specify where 0,0 is for xy. when i tell it G10 L2 P1 X-845 Y-850, the G54 line updates just fine but still i have to press up to make the laser go down toward me. i can place the objects i want engraved out of the boundaries for now but its kind of annoying

Please provide the following:

  1. Screenshot of your Device Settings window
  2. Run this immediately after running an homing cycle on your machine and return the output:
$!
