plasma thc not wotking

[matin]

Dear sir ,

when I cut , I didnt receive up /down signals to mach3 and not any up/down led
blinking, But I can read the voltage correctly on mach3 dro. The pwm sensor is
new.And all mach3 settings are correct. I have this up/down signals with another
pwm sensor , But in that sensor the voltage is not correct.

Therefore I dont have any movement on thc dro .

What can cause this ?

I test on 19 gauge stainless steel .

The controller Is Blade runner with pwm sensor .

What must I do ?

Best regards,
