[3DP] KP3S Marlin 2.1.2.5

KP3S에 Laser 추가를 위해 Marlin 으로 빌드했었다.

자세한 내용을 정리하지 않아서 정리해 본다.

KP3S Marlin Firmware로 검색하면 Kingroon 자료가 나온다.

How to Set Up Kingroon KP3S Marlin Firmware

Marlin is one of the best and most powerful 3D printer firmware. It is also available for the Kingroon KP3S 3D printer. Today we will show you how to build Marlin firmware for your KP3S and set it up.* Before that, we must remind you that the Marlin is a t

전에 LCD가 90도 회전되는 문제를 해결하지 못했는데 원래 안되는 것 같다.

그래서 LCD 마운트를 사용하는 것 같다.

Marlin 최신 버전으로 다운받아 지난 번 처럼 Configuration만 바꾸려고 했는데 설정값이 검색하는 곳 마다 다 다르다.

그냥 기본 설정으로 해본다.

1. Github에서 Marlin 다운받고 release 에서  Configuration 파일을 다운 받는다.

https://github.com/bdwilson/KP3S

2. Configuration 파일을 Marlin 에 덮어 쓴다.

 

이렇게 하려다 귀찮아서 일단 release 디렉토리의 robin-nano.bin으로 펌웨어를 바꾸고 해본다.

2025.03.27

release/no_bltouch/robin-nano.bin으로 바꿨는데 문제가 있다.

1. Z축이 아래로 내려가지 않는다.

2. FAN 을 켜면 고주파 소리가 나고 돌지 않는다.

robin_nano_cfg.txt와 configuration.h를 비교

#define Z_MIN_ENDSTOP_INVERTING true

FAN은 PWM으로 조절되고  D1 이다. 100% 미만은 스위칭 소음이 있다.

FAN 자체가 돌지 않는 문제가 있었다.

전에 Laser 테스트한 configuration을 지운 것 같다.

Laser를 위한 작업을 하면서 몇가지 수정.

2핀 커넥터를 PWM용과 24V 2개를 사용

PWM은 GND와 연결이 필요하여 DIR로 변경.

 

X X DIR GND
