Cezar Darci Zanon It may have triggered its auto protection action. We tried to lift the nozzle all the way to the top, then we lost control until we push the X-axis a little bit down. If your prints are not oversize in cura, please send your files and videos to , our guy will help you. As for the firmware, it is no need. The firmware only transfer your printer into ET4 with its latest version.

My ET4 PRO printer stop printing after +- 90% of the printed design, is it normal? Should I modify my firmware v3.0.0 to V1.0.2?
