I've had this table up and running for a week now and the set up is Mach3, Gecko 540, CandCNC B.o.B interface card and a LCTHC. Initially, everything went fine I had all the axes adjusted and was learning how everything functioned together. When all of the sudden the Z-Axis would stop homing in the right location, so if home was +1" it would be +1.25", then I noticed the pierce height was drifting one time it'd be .75" then the next time say .1". One other thing I can't figure out is the THC quit working about the same time. If I set the tip voltage at 100v it'll just cut at whatever it wants, however, if I shut off the tip saver it'll obey the tip voltage commands. While I thought I could live without the tip saver function it still doesn't solve the pierce height issue or the loss of the Z-Axis height. I readjusted the Z-Axis and played with Mach 3, but I'm not sure if it's software or hardware at this point. I'm still fairly new to all of this unfortunately.
Thanks in advance for any help you might be able to offer!
