MAch 3 THC question

[wickedinhere]

My THC seems like its not reacting fast enough i normally cut 16 gauge and its pretty wavy. By the time the thc reacts and moves up it needs to move back down but takes too long and the torch is too high to cut. I know there is a way to make it react faster but cant fine any good info on it.

Span gap and THC rate. Span gap is located in your cut profile and THC rate on the settings tab.

My THC rate is at -30 that was the setting it was at i did change it. Should it be a negative number? I would think it be 30 or +30 not -30.

-30 Is fast and can work change your span gap 2-5/4

Yes negative number is just how it shows up

Here is a pic of the settings, i completely forget about the cut profile settings i will adjust them next. What about the 60% setting above is that correct or should i change that?

Antidive is a corner lockout meaning if your motors decel 60% lower than your programmed feedrate (think corners) THC locks up until it reaches 61% of the feedrate then THC unlocks.

Alot of things in motion you have used for along time working together to give you good cuts. When you start to cut exotic material and corrugated you want to learn where and when to tweak these options. The best part is your table is part of the 1% of machines out there that allow you to actually change any of these values.
