General Mach Discussion / Re: Physical buttons for plasma
« on: January 27, 2016, 01:30:26 PM »HI Dave. Mach3 has anti corner dive built in. IF teh combined vel drops below the setting it locks out THCdown from working. You still get the THC up function to prevent head collision. Most set it too low.
IF you set this too low teh head will dive due to teh THC trying to correct teh voltage as teh Vel slows down for a curve. How far it will dive is a function of how slow teh Vel gets in that particular curve and where you have teh cutoff point set to.
Thanks, i did know that but maybe i need to revisit the settings, messing with sheet cam looks good on paper but i'm not convinced it even updates theTHC in time when running unless you switch THC off way in advance which is a bit pointless.
What sort of % is recommended in the anti-dive DRO?
Also, I gather there is no existing function that addresses my suggestion of stopping downward signals IF there is no corresponding fall in volts received???
