Arduino Nano laser not firing and Y axis not moving

Thanks to previous help, I discovered which board I have (Arduino Nano) and with that information I was able to do more research and used the Arduino IDE to upload GRBL into the library. I then opened LB and used the GRBL M3 option to set up my machine.

After all of that, my laser (which is not firing) will move along the X axis but not along the Y axis.

What am I missing?

Before the firmware update, my laser would fire but not move on either axis.

Probably you need to set $32=1 in your config settings. That and there might be another one to change. Go to the console in LightBurn, and type $$, then paste the results here.

Here is what shows up when I enter $$

$0=10 (step pulse, usec)

$1=25 (step idle delay, msec)

$2=0 (step port invert mask:00000000)

$3=0 (dir port invert mask:00000000)

$4=0 (step enable invert, bool)

$5=0 (limit pins invert, bool)

$6=0 (probe pin invert, bool)

$10=3 (status report mask:00000011)

$11=0.010 (junction deviation, mm)

$12=0.002 (arc tolerance, mm)

$13=0 (report inches, bool)

$20=0 (soft limits, bool)

$21=0 (hard limits, bool)

$22=0 (homing cycle, bool)

$23=0 (homing dir invert mask:00000000)

$24=25.000 (homing feed, mm/min)

$25=500.000 (homing seek, mm/min)

$26=250 (homing debounce, msec)

$27=1.000 (homing pull-off, mm)

$100=250.000 (x, step/mm)

$101=250.000 (y, step/mm)

$102=250.000 (z, step/mm)

$110=500.000 (x max rate, mm/min)

$111=500.000 (y max rate, mm/min)

$112=500.000 (z max rate, mm/min)

$120=10.000 (x accel, mm/sec^2)

$121=10.000 (y accel, mm/sec^2)

$122=10.000 (z accel, mm/sec^2)

$130=200.000 (x max travel, mm)

$131=200.000 (y max travel, mm)

$132=200.000 (z max travel, mm)

What version of GRBL are you running? Seems its missing some settings that are in the newer versions

I’m running GRBL 1.1
I did discover that I had a bad stepper motor driver which I replaced today. That solved my problem of my Y axis not moving. But now the direction of both X and Y axis are inverted and when I try to engrave an image, it goes super fast and doesn’t actually make any marks on the wood.

Here are my new settings after replacing the bad piece.
