Bitsetter not working after switching from Lightburn

1

I am having issues with using my bitsetter after using Lightburn (and Jtech laser). I’m a newbie with the laser side of things. The bit goes down the Bitsetter light goes from red to green and then I get a limit switch error. I have the macro for switching to CNC mode but I am thinking my Grbl settings may be off somewhere else. Any help would be appreciated.

This is my “Use CNC” macro:

$32=0; disable laser mode
$10=255 ; Sets $10 to original value
$20=1 ; reenable soft limits
G10 L2 P1 X0 Y0 ; reset work origin

This is the settings that I pulled off of Carbide Motion:

$$
$0=10
$1=255
$2=6
$3=0
$4=0
$5=1
$6=0
$10=255
$11=0.020
$12=0.002
$13=0
$20=1
$21=0
$22=1
$23=0
$24=500.000
$25=2000.000
$26=25
$27=1.500
$30=1000
$31=255
$32=0
$100=80.000
$101=80.000
$102=200.000
$110=5000.000
$111=5000.000
$112=3000.000
$120=500.000
$121=500.000
$122=500.000
$130=1250.000
$131=1250.000
$132=155.000

Light burn has a macro to return to cnc mode. You can also send config.

What’s the actual error message?

I haven’t used Motion in a while, but I’ve always had soft limits disabled.

Thank you so much! That was the issue. I’ve been trying to figure out the correct macro to use. Someone in a feed had the $20 toggle from a 0 to a 1 when going from Laser to CNC. Keeping $20=0 and leaving it be was the solution.
