I have a ender 3 v2 printer and i recently got the 1.6w falcon laser attachemtn, i got it hooked up and at first couldnt get it to connect, it was because lightburn kept using com3 when it should be 7, when i switched it the laser would activate and start autohoming but going the wrong way, it would get to end and start skipping belt, i finally unchecked autohome and now i can switch com ports without it happening but when i try homing it it still goes the wrong way and has wrong size set, what am i doing wrong?
LightBurn isn’t directly involved in how your machine homes. The machine configuration does this.
Was the machine working correctly for 3D printing before you added the laser? Did you make any hardware or firmware modifications when you connected the laser? Make sure that you don’t have the stepper motor connections plugged in backwards.
Can you explain what this means?
yes 3d printer was working fine, and it isnt even powered on im using the laser attachment that comes with its own control box, its the creality falcon. and when i try to make it home it goes right instead of left and bed comes forward instead of backwards to hit limit switches, as for the size i meant bed size but i think i managed to figure that out so far
Okay. Didn’t realize this included a separate controller.
First make sure that you absolutely have not plugged in anything backwards. If that’s not the case then you’ll need to make some GRBL configuration changes. This seems odd, though, if the upgrade kit was designed with your printer in mind.
Can you run these commands in Console and return output:

$I

$0=10

$121=500.000
$130=220.000
$131=220.000
ok
an to fix bed size issue i had to change $130 and $131
i just think something is inverted somewhere cuz i check wires and there is only one place each would fit so i dont think i got them wrong i think its a setting somewhere
ok so when i use move panel and click the arrow on the right my laser moves left and vise versa, now the bed when i hit down it moves down (towards me) and up it moves Away from me, is this something with the invert settings?
I’m glad you tested the jogging directions.
This means you can invert both X and Y and that will fix jogging as well as the homing direction.
Set this to $3-7. This will invert X and Y. It does not invert Z.
Then test homing and jogging.
that worked thanks so much
