I re-share the post,

I re-share the post, as first video got black Chilipeppr screen and I recorded another one.

I am unable to probe using TinyG 442.04 with less than 18mm/sec feedrate. That is too much for PCB probing, as I am using quite expensive bit.

I have recorded 2 probing cycles starting with F20, then F19, F18 and F17 resulting in machine freeze, then RESET and another cycle.
You can see the stepper motors LEDs blinking for G38.2 Z-20 F20 (and F19, F18) when machine works, as expected, and just a single short red LED blink after issuing G38.2 Z-20 F17.
Does anyone face similar issue? Can it be the board malfunctioning?

You will find the video here: https://www.youtube.com/watch?v=R6uxGo4S_Yo

EDIT: Video link updated -> I have recorded another video, as the previous one got Chilipeppr black screen in YouTube.
