Missing $30, $31, and $32

LightBurn Hardware Compatibility
1

I bought a Laser Engraver off Ali Express a few months ago which does not have much info on it. I know the board is a Eleksmaker but I cannot get the power I want. It barely marks the board. I have searched all over and found comments about changing the settings for $30 and $32 but as you can see below I dont have those values, any idea why? I have tried both GBRL driver and the GBRL-m3 The laser works really well with Eleksmaker software but I really want to make this light burn software my go to burning software. any help would be appreciated.

$0=10 (step pulse, usec)

$1=25 (step idle delay, msec)

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

$3=1 (dir port invert mask:00000001)

$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=80.000 (x, step/mm)

$101=80.000 (y, step/mm)

$102=80.000 (z, step/mm)

$110=5000.000 (x max rate, mm/min)

$111=5000.000 (y max rate, mm/min)

$112=5000.000 (z max rate, mm/min)

$120=200.000 (x accel, mm/sec^2)

$121=200.000 (y accel, mm/sec^2)

$122=200.000 (z accel, mm/sec^2)

$130=5000.000 (x max travel, mm)

$131=5000.000 (y max travel, mm)

$132=5000.000 (z max travel, mm)

That would be a very old version of GRBL, 0.9 or earlier. You would need to use a firmware utility to flash the board to a newer version, assuming it’s compatible.

Ok, Thank you, I was looking into that after I found some info on $$ saying my version is 0.9. My board is a Eleksmaker mana se 3.2. I was looking into trying to update the firmware but I was unsure if I just need to find the latest GRBL code or do I need to use Eleksmaker firmware only? I did finally get it to burn last night after what I guess was an option I found when looking around for my laser to do measurements in MM with a diode laser. It was set to CO2 mm. I do want to update the firmware if possible

Thanks again

I would look to see if there’s Eleksmaker specific 1.1f firmware. You can also download the trial of T2 Laser, as that software has a firmware update utility in it, and a few different versions included.
