Now the origin and home is in the upper right corner of the grid
The jog function, which I never use, works normally IF one is looking at the laser from the front where the controller is located. However, nothing else works. If I try to frame something it’s as if the location of the object is inverted and the head crashes
What exactly does G10 L2 P1 X0Y-460 do?
Please try to address every question raised. It’s hard to form a cohesive understanding when things are coming in piecemeal.
I thought you confirmed that you changed origin to bottom-right.
Can you please confirm how you’d like the jogging functions to work? Is it according to the diagram that I showed? If not, please be explicit about what you want to happen.

ok
Right now the concern is that the laser doesn’t function Except for the the jog which seems to performa as it would if the laser was turned around 180 degrees,
Figured it out. The problem is the -460 which screwed the pooch. Changed it to zero and all is functioning again. May need new belts!
I’m not following. This should put you back at square 1. Are you saying it’s now working as expected?
Yes, but clearly the -460 in the command string was not working. I tried something similar a few days ago with no success other thang chewing up belts. I appreciate your help but I have a project to deliver in a few days and I was supposed to have a working large format laser two weeks ago…this is the 3rd laser in that time and I can’t afford to brick it. I was hoping for a simple command to rotate working grid 180 degrees as I access the lase from the the lower right side. My other laser had the controller exactly there and it was a reasonable work flow. I have to crank out a bunch of bison guitar straps in time for the customer’s trade show…so getting nervous. I do appreciate your help. BTW where are you located?

In rereading the thread, the problem really wasn’t the laser, it is simply the layout in Lightburn. Ideally the hardware would home on the opposite side of the y axis, but the Chinese read right to left…i guess.
I’m a bit stunned because I’m now realizing that you were actively working in opposition to me which now makes sense. You were likely a single tweak away from it working as intended.
No matter. Glad you have what you need.
If you want to go back fully back to your original settings then you’ll also need to make this change:
$10=1
I will revisit this thread once I get the project done and see what i can do. Interestingly $10=0 was the default. I save the Gcode yesterday when I was calibrating the X and Y axis…But I flipped it to on and see if I notice any thing interesting
Thanks again,
Bob
Interesting. Machines that zero origin after homing and do not require a work offset typically will have $10 set to 1 or 3 to work in machine coordinates.
Having $10 at 0 won’t pose an issue as long as a work offset is not applied.
Thanks for the info. Before I delve back into the issue I’ll read up on Gcode. Right now all I need to do place a mm scale along the Y axis of the extended bed originating at 00, which is inverse the scale on my current laser. I have the bed and laser aligned within a mm for production.

you have set the machine to run backwards ,all cnc/laser/cutter /whatever home and 0,0 equals the lower LEFT corner as you show in the picture you are trying to use upper RIGHT corner which wii not work . Here is how to fix your machine set it up in accordance with the instruction book that came with it NOT as the software says now where the machine says LOWER LEFT corner is will be the LOWER LEFT CORNER against the wall or corner now when using GRBL laser software put your material to be cut /drawn so that it it is at the lower left corner and manually move the head to the lower left corner of the material and then in the software hit the home symbol now the software and the machine know where the home position is now set up your design in the program and insure that the lower left corner of the design is at the lower left corner on screen and hit go and it will work ,I had a simular problem with a pen plotter why because I and I suspect you too are LEFT handed.
Actually UPS resolved my problem last week! They took the POS back to the manufacturer via Amazon. I restored the original factory Gcode and did some more work with it, but it had a fatal flaw, which the manufacturer describes as “normal”. There was no power switch on the controller, and whe power was applied the laser fire a 2 or 3 second burst of 22 watts through what ever happened to be placed underneath. Not to mention potential eye damage, but I could easily imagine a product with hours of work in it (I use the laser in my leather business) with an uncommanded brunt hole.
I have subsequently decided to make my own extension kit for my current laser.
I may have over complicated the problem. My current and returned laser both homed in the front left corner. The X axis was 110mm and the Y 460mm. Due to space constraints I had to place the laser 90 degrees from where a conventional one would be placed. Really all I needed was the ability to rotate the graphic 90 degrees so placement and movement on the laser would coincide with directions on the screen. I was oping there was a LB command to rotate the viewing perspective without changing any functions of the machine if that makes any sense?
Thanks so much for taking the time to reply. BTW if you want to avoid a diode laser that will burn random holes in your work space, don’t buy any that start with Z…
Bob
Not what you wanted but have you considered just rotating the monitor display setting in windows ?
Could also lie sideways on my desk… 
Bugga, I can’t believe I didn’t think of that. I have a dedicated system for my laser so rotating my screen is no big deal for me, BUT I might change my mind tomorrow when I install my extension kit.
So are you in Oz?
