This is precompiled Marlin firmware for Creality Ender 5. Proceed on your own causion but this should fix issue with OctoPrint and Ender 5 (1.1.5 board) stepper motor stopping mid print on one of the axis.
-
Configuration file by firestrife23 for Ender 5 and Marlin 1.1.x
-
Config is changed for 800 step lead screw on Ender 5 (Z axis)
-
Build using Arduino IDE
-
Board config from Lauszus
-
Processor was set to ATmega1284 or ATmega1284p (16MHz)
-
Post by 1970s_MonkeyKing and post by gekkonaut that firstly mentioned how to solve this issue.

Firware is optimized (sizewise) using:
compiler.c.extra_flags=-fno-tree-scev-cprop -fno-split-wide-types -Wl,--relax -mcall-prologues compiler.cpp.extra_flags=-fno-tree-scev-cprop -fno-split-wide-types -Wl,--relax -mcall-prologues compiler.c.elf.extra_flags=-Wl,--relaxbased on this post which results in 92% device memory used instead of 96% with not optimized build.
You should be ready to load firware with or without bootloader from folder precompiled firmware using OctoPrint.
For OctoPrint you need to install avrdude and plugin Firmware Updated, and later set path to avrdude (ex. /usr/bin/avrdude), AVR MCU to ATmega1284p and AVR Programmer Type to arduino. Connection set same baud rate as on main page of Octoprint in "connection" section. Enable post-flas gcode with M502;M500.
In my case I had to call additionaly M502 and M500 (due to "Err: EEprom version on Ender display") reboot and G28 (homing after flash).
- Check if there is any better Configuration file out there
- Automatize releases and triggers if possible compiling firmware based on new Marlin releases in the cloud so it is automatic and always up to date.
- Set home to top-right corner as currently it goes to bottom left after the print.
