Help in Scalar M configuration

First of all, I want to thank you for your work, I have been working on making my Scalar M 3d printer, (I will make a donation soon). 
I made it with some small changes, I am currently stuck in the configuration, I have the autoevel and calibrated the steps of the axes working , however, I have problems in the printing, the infill do not finish printing well and the Print is deformed, I am not sure if it is error of the configuration in Cura, (by the system bowden of the extruder, retraction speed, acceleration), or the settings of jerks and retraction in the firmware.



I would greatly appreciate the help, below attached image of the impression of a cube of 10x10 mm
