Code sharing works as follows:
Your slicer turns STL models in a bunch of gcode commands & lets you save them in a .gcode-file. Open this file (the one you put on your SDcard) in a text editor - it is human readable text. Copy the first lines of this code into clipboard & paste them here in your next answer - that’s it.
When copying the first line of code please include all lines from that begin with M104, M109, M140 & M190 - these are the gcode commands that order your SV04 to heat up nozzles & print bed to target temperatures and to wait until the the temperatures are reached. Your print process might hang up here. Therefore it would be helpful to know the temperatures displayed (bed & nozzle/nozzles). There could be lots of M104 gcode commands in the file - relevant are the ones in the beginning that precede a M109 command.
Next question: Did you ever run a PID calibration on your SV04? Maybe this could solve the problem.
