Hello
I have been using an older model of Ender 3 Pro w/o any issue. Recently, I upgraded the board to 4.2.7 and loaded the appropriate firmware from the Creality website. (The fm from Jyers did not load.) I leveled out the bed as always. Now, loading a routine calibration gcode with Octoprint or an SD Card it just doesn’t work correctly. I created some simple gcode with the help of CoPilot and confirmed the motors work fine, there is no clog in the tube, the heaters heat correctly, the extruder moves around ok. But if I try to print a simple infilled square it just prints the outer edge, moves up and stops.
Would appreciate any input from the community. Other than putting the old board back in, I have run out of options on my own.
