hi again everyone 
because of the fast and awesome help yesterday I try it again today.
I having trouble with the “Laser test” and “check size” option.
I’m searchin google and this forum for quite a while now for a solution, but I got there only partial.
I have a Laseraxe laser with grbl_v1.1f-laseraxe Firmware.
I tryed with M3 and M4 for TOOL ON and M5 for TOOL OFF
ALso I used values between 1-12 % for “CHECK-SIZE POWER” and “TOL TEST POWER”. I also tryied “TOOL TEST DUARTAION” having it 0.
with a power of 10% it starts burn my leather.
with a power less than 8% I cant see the laser dot.
here comes the issue:
when I hit the test button or check size button the laser dit is only short visible. and disaperas very fast.
In the software I used before (laseraxe) I could turn on the laser on 1-2% the dot was visible and I could focus it correctly and see my position, see my test size, etc.
how can I get this with laserweb4 ?
is there something I did wrong ?
hope somone can help. this is the last piece of the puzzle to have a nice working setup.
thank you so much for help
max
