Marlin: Modify Calibrate/Leveling probing profile

Hi, using 1.1.9 on a delta and the probing is woefully slow. I have tried changing probe speed etc, but the issue is the actual cycle profile.

With G33 or G29 it homes to the top then zooms down to about half way.
It then slowly approaches the bed until about 30mm above the bed.
It then creeps at an even more dead-slow pace to the bed and probe trigger.
Repeat a lot of times.

I'd like it to zoom down to about 20mm above the bed, skip the intermediate creep and just use the dead-slow to the bed to trigger the probe.

I cannot seem to find where that probing profile is defined. Anyone?

By the way, I tried using Marlin 2.0 on a RAMPS board and it does a much better job at the probing style, but 2.0 will not compile for my Trigorilla board.

TriGorilla is a integrated main board that is integrated with the Mega2560+ramps 1.4;

Marlin 2.0.x Requires the Arduino 1.9.0 IDE compiler or it will not compile.

Er, not quite so, it is actually the RAMPS v1.3, but Marlin 1.1.9 now includes a board defiintion for Trigorilla. BUT, that is not what I was asking.
I want to change the probing profile. To wit:
from Fast->Slow->ReallySlow->Bed
to Fast->ReallySlow->Bed

I found the issue for marlin 2.0 and it does compile with Arduino 1.8.6. The issue is caused by some lines with both commands and comments in them that Arduino crashes at. Just move the comments to their own line and all is good.

Building Marlin 2.0


To build Marlin 2.0 you'll need Arduino IDE 1.9 or PlatformIO. We've posted detailed instructions on how to build Marlin 2.0 for ARM.
