Ruida 6442G and Leadshine DM556 trouble

[deflord]

Hi all!
I build laser cutting, and have strange problem.
My config:
Controller: Ruida 6442G
Drivers Axe X and Axe Y: Originally Leadshine DM556.
Description of the problem:
1. Laser Head in Origin. Click Pulse and see dot on paper. Ok.
2. Start cutting big file with big quantity little contours (file added to post).
3. After end cutting laser head back to Origin. Click Pulse again and we see that the dot has moved down (about 3 mm) and to the left (about 5 mm).
This is not mechanic problem. For test i connect another controller (AWC 708C Lite) and all work correct.
I connect to Leadshine driver over ProTuner, change parameter Active Edge, "Falling" change on "Rising", but nothing change
Thank for your help!
