  1. THIS PROBLEM IS SOLVED... I changed the voltage from 1.06V to 0.86V in all driver stepper and works without problem... but I have the last problem, the Autoleveling that doesn't work 😞 I will open a new topic. Thanks. Federico.
  2. Hello guys,After weeks of hard work I managed to install the Marlin 1.1.8 firmware on my RenRen3D, which had self-leveling problems, so I decided to install the BLtouch and further upgrades.Fixed these first difficulties now when I go to print the Gcode, which I tried to generate with Slic3r, Cura and Prusa Slicer, they all give the same result, that is, the first layers have a fluid movement while the following ones the extruder starts to "jump" voluntarily.Below I insert the video and some photos. https://www.youtube.com/watch?v=B9Ap712Utrk https://www.youtube.com/watch?v=p6_w8HGQfrg Can the firmware be installed that I have to fix? or some settings of Cura or something else?Thank you guys.Greetings.Federico
