It starts printing at a normal speed but then slows down considerably #26

My printer is M02 Pro, it doesn't get recognized as /dev/usb/lp0 but as /dev/ttyACM0 instead. If I print over Bluetooth the speed varies throughout the print but it's generally fast (normal), however, when using the serial port it starts out fine and then slows down to the speed of ~2-3 lines per second. I tried playing with the baud rate but it doesn't seem to have any effect.

Same here. Tested on an M02 (T02) via USB and Bluetooth.

Just tried it with newer hardware (Pi 4 instead of Pi 3B+) and 64bit instead of 32bit OS. Now it works at consistant good speed.

Can you tell us how you did it? Like, what OS specifically and if you tested over bluetooth or serial port (usb)

Raspberry Pi 3B+ (slowdown)

Linux hostname 6.6.47+rpt-rpi-v7 #1 SMP Raspbian 1:6.6.47-1+rpt1 (2024-09-02) armv7l GNU/Linux

Raspberry Pi 4 (working normally)

Linux hostname 6.6.31+rpt-rpi-v8 #1 SMP PREEMPT Debian 1:6.6.31-1+rpt1 (2024-05-29) aarch64 GNU/Linux

Both testes with usb connection (ttyACM0).
