Title: THC Min Speed Button - Documentation?
Post by: raedioactiveman on September 28, 2015, 12:56:23 AM
On the Plasma screen there is a button that is labeled "THC Min Speed" with a default value of 60%. What does this button actually do? I noticed that when the button is activated, output 6 on the diagnostic screen flashes even though output 6 is disabled in the ports and pins screen.

THC Min Speed

If your feedrate is set at 100"/min

and CV dictates that feedrate slows down in a corner below 60"/min  (60%)

then Mach will ignore up/down commands from the THC

until feedrate again climbs above 60"/min
