Qtdragon_hd wrong preview

I have setup a knee mill with qtdragon_hd within these limits in mm
X 0min 950max
Y -380min 0max
Z -400min 0max

But does not display in preview correct the path.
How can config this?
also does not show me in manual mode
spindle set rpm slide bar and spindle override rpm
 

What version of linuxcnc are you using?
Can you post your config files?

How is the path displayed wrong?
