Motor lost his position

Hello everyone, on my printer I use a raspberry pi 3B and a nanodlp card.
I had some problems recently with my printer. Some layers of my model are much smaller than expected. In the end I end up with a "flattened" model, half of the layers are much thinner while the other half is correct.
My hypothesis is that the engine loses its position during the printing process and reposition itself several times on the same layer.
I noticed that at the end of the printing process the engine doesn't know where it is anymore. When I give it a G1 Z0 command, it is shifted about 10mm from its zero (all my gcode is in absolute).
However my motor parameters are well set.
I don't know where the problem comes from...

Re: Motor lost his position

gcode sequences are wrong on your settings
