Hello dear team, my laser suddenly only fires at 100%. I have a neje a40460 which is connected to pin PC9 of my skr pro v1.2 and I have a TFT3.5E3V3.0 screen which has always worked. I always got by well in Marlin mode, unfortunately it no longer recognises my SD card and USB in Marlin mode. I have formatted my cards to Fat 32. My MPCNC is about 4 years old and is configured with Marlin. What should I do? Can you PLEASE help me, I am already at my wits’ end. Thanks, regards, Gerhard
