Hi all,

H have a home made plasma table running Mach 4 with a Warprunner THC. The THC is new to the machine. I believe I have my Warprunner wired correctly, but it's misbehaving, it dives and crashes into the material. I believe my issue is the Z is just moving too fast. The THC correctly senses it's too high, then it launches the Z down at 150 IPM then crashes before it can pull back up.It's hard to tell as it all happens in an instant. Can I tell the Warp runner what speed to adjust the Z by? I can of course change the Z speed in motor tuning in Mach 4 to reduce the max speed. Either way, what is a good speed to set the Z to for THC use? Want it fast enough to follow any contour, but I think mine is too fast for the THC.

Thanks
