Tonight I found the problem.

The retraction was too long causing the melted plastic to get out of the teflon tube then causing a clog, I changed the retraction from 1mm to 0.5mm

I increased the voltage on the drivers too, without multimeter, I just installed a bigger heatsink on it and increased it by 1/8R and things looks running good.

I just hope the E3D V6lite support I'm printing will be printed well because I really need it to replace the stock hotend, I'll keep you upgarded !!
