New GRBL Version due to new VisiCut Version

A project log for Inkscape + VisiCut = Perfect Lasercutting Workflow

A brief summary on how I use my K40 laser cutter with custom GRBL controller. However, this workflow should work for all GRBL lasers.

I was a but of a struggle going from one working solution to a new one. I'm actually not there, yet since I seemingly also have to upgrade my GRBL version to allow the new Visicut to work properly with my laser setup.

Apparently, it is assumed that G0 moves never use the laser. That makes sense. However, my GRBL version, even though is has laser mode already (1.1d) does not turn the laser off during G0 moves. That's only available in 1.1f and newer. 

Visicut has a setting to enforce the laser off during G0 moves but that breaks other things in the software which I think should still be resolved but hey, upgrading GRBL is probably still a good idea.

Here are all my settings:

$0=10 (Step pulse time)
$1=255 (Step idle delay)
$2=0 (Step pulse invert)
$3=7 (Step direction invert)
$4=0 (Invert step enable pin)
$5=1 (Invert limit pins)
$6=0 (Invert probe pin)
$10=3 (Status report options)
$11=0.010 (Junction deviation)
$12=0.002 (Arc tolerance)
$13=0 (Report in inches)
$20=0 (Soft limits enable)
$21=0 (Hard limits enable)
$22=1 (Homing cycle enable)
$23=1 (Homing direction invert)
$24=200.000 (Homing locate feed rate)
$25=4000.000 (Homing search seek rate)
$26=250 (Homing switch debounce delay)
$27=5.000 (Homing switch pull-off distance)
$30=1000 (Maximum spindle speed)
$31=0 (Minimum spindle speed)
$32=1 (Laser-mode enable)
$100=157.575 (X-axis travel resolution)
$101=157.575 (Y-axis travel resolution)
$102=32768.000 (Z-axis travel resolution)
$110=8000.000 (X-axis maximum rate)
$111=8000.000 (Y-axis maximum rate)
$112=40.000 (Z-axis maximum rate)
$120=1000.000 (X-axis acceleration)
$121=1000.000 (Y-axis acceleration)
$122=1000.000 (Z-axis acceleration)
$130=300.000 (X-axis maximum travel)
$131=200.000 (Y-axis maximum travel)
$132=25.000 (Z-axis maximum travel)

 Luckily, my new favorite tool LaserGRBL allows me to export this without a big deal.

I'm more concerned about the GRBL config file and all it's details. But it's still mornging.
