I see that you dont use a 20% increase in maxvel over Max_Acceleration as usually adviced

Edit: Just saw yo do this but had all values on INI

why is acceleration that much higher that max velocity? what is the pourpose on this?
I mean, in your plasma config BigJhon

Acceleration is usually 10 - 20 times max velocity I've found.

I think that works out to be a good ratio to get up to velocity within most machines physical capabilities. Acceleration is speed per second per second... kinda like falling you get up to speed pretty fast then your in the cruse mode.

If acceleration = velocity then it takes a whole second to get up to your max speed.
That's really slow.
