During my prints, octoprint disconnect randomly from my printer.
It starts to occur when I change my stock mainboard (Creality v.4.2.2) to BTT SKR Mini E3 V2 with my self-compiled Marlin 184.108.40.206. Currently the serial port config is set as:
#define SERIAL_PORT 2 #define BAUDRATE 115200 #define SERIAL_PORT_2 -1
I am using the stock LCD 12864 screen.
Also note that connection to my printer starts to be slow since my change of mainboard. It used to be less than 1 second and now it takes around 2-3 seconds for Octoprint to connect.
Another thing is that during connection, it is very prone to fail to connect if I have gcode file in my printer SD card and the startup M21 command triggered the disconnection.
Switch to official Raspberry AC adaptor (5.1V 2.5A), change my USB cable to a shielded one (I am now using the one came with BTT mainboard), put a fan on top of the Pi to prevent overheating, tape my USB cable power pin, also unplug my stock 12864 screen as I thought I read something about screen cable to cause serial connection problem. All the above fail.
Not yet, but I don't think it is a plugin problem
