Tmc3in1 tip voltage not reading

Question on you guys
Im using Tmc3in1 THC, ESS and Mach4 and it seems not to read the tip voltage.
I have not yet connected it to the plasma but as soon as i enable mach it starts to count up slowly untill reaching to the max.
Ports and pins are all set according to the manual and yes instead of the plasma ark I tried hoking it up on a 19v power supply but the actual tip voltage wont change it just keeps ramping up
