Thread cutting problem G76

Hi all. There is a problem with cutting threads on a lathe.
I'm writing code
G0 X32  Z2
G76 P4 Z-10 I-0.2 J0.01 K4
G0X50
G0Z100
M5
M30
The cutter moves by a certain amount each pass.
the result can be seen in the photo.
I have an encoder with 3600 pulses, installed through a pulley, so the setting is 3552 pulses per spindle revolution.

But we see that for one revolution we have the value 1 in the parameter: hm2_7i95.0.encoder.00.position

Your post led me to this diagram.
Is this what you meant?
I will put a separate sensor on the spindle shaft and connect it instead of the Z mark to the input of the control board.
To do this I will need to convert the encoder operation to  single ended mode operation?
 

Hello. I succeeded after installing a separate sensor instead of the encoder mark.
I used the diagram that I showed in my previous post.
Installed the sensor SS441A.
