Wright CNC THC Up and Down Signal Active-HELP

Post by McCordDesign »

Since I told my Wright CNC machine I was getting a new table its been giving me the finger.

New status error I've been receiving in Mach 3 is (Thc up and down signal active. Clear it first.) Never had this error before and didn't do anything out of the ordinary at my last close down sequence.

It won't allow me to reset and BUT if I go into ports and pins and over to milling and disable the Allow THC option it allows me too reset and everything looks normal but the x, y and z still won't move at all.

Any ideas.

Thanks PS community

Go into ports and pins under inputs and un ab;e the THC signals to see if the clears it, if you are using a THC it may have died.
make sure no green check in the simulate boxes either.

I went and turned those all off and still nothing. Will a dead THC disable the entire machine? Mach 3 resets great but still zero movement from the x, y or z

Thanks

Does you BOB have any lights on, do you see any led lighting when you try to move any axis. The DRO changing means nothing as there is no feed back.
The THC would only effect the Z axis. Do you see any lights on the drivers, do you have more then one driver power supply?

The lights are on in the controller and no lights are changing on the drivers when I try and move the machine and one power supply
