THC not working

I am running the latest QTplasmac on a new build.
I am using thcad and that seems to be sampling ok cause I am getting good volatages.
The  voltage is getting sampled I imagine when it gets arc ok active is coming on when it gets up to 99% of feedrate.
Then while cutting, the voltages are changing while cutting a 3" circle from conversational tab, up or down never comes on. The piece is propped up a bit so it is on a slight angle so it should be coming on. The voltages vary up to 10-15 volts.

I am pretty sure I am missing something in the config I guess or something I am not doing properly. 
Can someone look at my config I posted to see if something is wrong?

/edit   running 2.9 master with the latest QTPlasmac with ohmic probing. XYZ gantry working fine. Using thcad-10

Thanks,

You should set all the JOINT velocitys and accelerations to what you require then set the corresponding AXIS velocity and acceleration to double the JOINT values. Then TRAJ MAX_LINEAR_VELOCITY should be at least the same as the highest JOINT velocity, for QtPlasmac it could be √ jointXmax_vel² + jointYmax_vel²

 

Just to check my understanding. This is when both the X & Y  axes are both at max velocity  so travel is at 45 degrees using pythagoras. Is that right?

OK will try working on the config. I didn't think this mattered. I just threw up some numbers to get it working and moving. I think I understand the correlation though.

Thanks,
