Help. My Ender 3 Pro, with an upgraded silent 4.2.7 mainboard and sprite direct drive extruder, wont start printing after heating the nozzle and bed. After the nozzle gets to temperature, the fan goes up to 100% speed, and the progress bar moves to the end and the heat shuts off. I tried replacing the motherboard but the problem continued after a couple prints. I also tried reformatting the micro SD card, using a new SD card, using PID autotune, and reslicing the STL file but they didn’t fix the problem. The video shows a sped up version of what the printer is doing.
I have the same issue with E3v2. Did you ever get it solved?
No, sadly.
