Hello, I am hoping to get help on doing a multi-stage print for a PCS gift for one of my NCOs. I tried to follow the tutorials that I could find online however, when I go to frame the cut to ensure it is where I want it before I print for whatever reason the laser maxes out going in both north and south on the Y axis. I ensured that the other segments (in different layers) had output and show toggled off before actually printing, I ensured each segment fit within the confines of the bed, and that the preview showed it was good. When I manually moved the laser with the move tool it also moved the correct distance so it shouldn’t be a scaling issue. I have limited material so I want to get it right on the first try.
A couple of weird things that I noticed while trying to get this to work is despite having the laser start from the current position, it would still try to exceed the boundaries of my laser bed 400mm(Y) by 410mm (X) the size is well within these boundaries, and then it would head to the origin 0,0. Input manual movements still go the correct distance however one attempt at using the print and cut tool I also received the error that my laser was at 861, 1095. I manually moved my laser back, and input the console code: G92 X0Y0; which seemed to briefly reset the issue until I hit get position and has since given me the coordinates in the screenshot. I can still manually input coordinates with any of the other options in move and it will go to the correct location.
I have attached screenshots of everything as well. Any help would be appreciated since I am semi-new to the software as I only use it for small easy projects and this is the first large one I have done.
Note: In order for the output to be positioned correctly on your laser, you must use Absolute Coords as the positioning mode, otherwise the output will not match the position of the print.
Switch from Current Position and it’ll work as it should.
Caveat: The machine must have home switches and be properly homed.
With that done, the LightBurn workspace will exactly match the laser’s physical platform.
A review of the various coordinate modes may be in order:
the reason I was using the current position was due to my machine atom stack A20 not having home switches and, for the life of me can’t fix my home button when clicking that it sends my device to -451,-451 instead of from the origin which I have set at 0,0 and if I use that feature it makes a horrible grinding sound. trying to reach a non-existent point. is there a way I could fix the offset and get the home to be 0,0 then? I have my device setting attached as well.
Put the laser head in the home position before turning the machine on
Without home switches, you must disable all the functions that depend on having home switches.
When homing is disabled, the controller assumes it is at the home position when it starts up. You must manually ensure that’s true so the controller’s coordinates match up with reality:
When you have all that set up and behaving properly, the offset will probably cure itself. If not we can proceed with further debugging.
