Recently i change the motherboad of my Creality Ender 3 for the new silent version called v1.1.5 (with TMC 2208).
Until this change, with no reasons, all my prints fail : The extruder stop working while the print process still continue in "air printing".
I test with old gcode (generated before the motherboard change) and new gcode freshly generated, same issues...
I don't change anything in my S3D profile (it's the basic S3D generated profile from Creality ender 3)
I check the nozzle, the ptfe tube, the extruder himself, all is ok.
For testing, i install Cura and unfortunely it work well and i haven't this trouble.
Help me i dont' want to use Cura !!
