Not seeing anything. Others more knowledgeable will jump in.
Do you have a sample of the project that has the problem?
Looks like you have ball screw drive so your $100 and $101 numbers of 100 are probably right.

its just a 3/4 inch by1/8 inch burnt spot on wood that is sort of divided into 5 parts . see pic

If you make a 100mm x 100mm square what size does it burn?

it makes an 1\8" dot

Or maybe 1/6th of an inch dot? Seems close enough to a factor of 25.4 for unit conversion error to be the likely culprit.

Your posted GRBL settings are the original ones?

First change the settings per the following values:
$100=1600.000
$101=1600.000
$102=1600.000
$110=1100.000
$111=1100.000
$112=1100.000
$120=3000.000
$121=3000.000
$122=3000.000
$130=290.000
$131=170.000
.
After a few tests you can change
$0=10
$12=0.020
if nedded.
