I have the problem that my 3D printer (makeblock mcreate) has been showing error code 04 for a short time. The pressure always ends differently. I’ve already looked for errors and have already informed myself on the Internet. It says that if the printer drops 6 degrees in temperature for 20 seconds, it will stop printing. But I stood there the whole time and the temperature fluctuated by a few degrees but never for 20 seconds and certainly not by 6 degrees.
