General Mach Discussion / inconsistant cuts, THC, older version

« on: August 09, 2011, 10:46:16 AM »

I purchased a plasma table from Dyna CNC (now out of business) several years ago using Mach 3 version D1.90.026. I am at wits end trying to get a consistent cut. I do not think torch height control has worked from the beginning. One of the problems I am currently having is SOMETIMES at the end of a cut when the torch should go up to "safe height" then travel to the next cut it does not go up, it travels to the next cut dragging on the metal then tries to go down and crashes (limit switch on z axis). Another is sometimes while cutting just fine suddenly the cut will not go all the way through for a short distance (maybe an inch or two) then it will penetrate and do ok after.

I was wondering if maybe going to a newer version some of these intermittent problems might go away? Can I install a newer version and see if it works with my machine? The version I am using is registered to Dynamic Plastic #061001, do I need to purchase a new version or is this upgradeable?

Many questions I know but I just do not know where to turn for help or what to even ask for.
