The latest (software) Chinesium
¶ Observations
- Only 2.4Ghz WiFi, with 14 channels, so you can finally use those who are prohibited in your country. According to device tree a rtl8723bs, but used driver is generic brcmfmac. It's actually a AP6212 which you can use to receive and broadcast in the FM radio frequency bands .
- No LAN
- Screws not configured in printer.cfg, so no convenient BED_TILT_CALIBRATE, you have to use the stupid Display tool
- CPU power management not configured or not available? Running 78°C at 50Mhz, real frequency not readable
- CST is Chinese Standard Time, right?
- Thumbdrive not mounted when connected during boot
- Desktop, best location for system software:
1395 ? Ss 0:00 /usr/bin/bash /home/mks/Desktop/myfile/ws/start.sh1403 ? Sl 0:02 /home/mks/Desktop/myfile/ws/build/mksclient
- USB 3 or 5V Rail seems to be underpowered. Voltage without load ~4.80-4.86V. SSD via adapter can put too much load on it. More stable after unplugging the display. Maybe good powered USB hub necessary for accessories.
- rk805 unhandled IRQ 24
- Omitted X & Y endstops, crashing into the end signals the drivers the end is reached.
- The mainboard fan is controlled by the extruder heater and not by stepper activity or the SOC temperature … o_O and replaced it with a more quiet Sunon.
- The klipper firmware configuration loitering on the system is wrong. Use it to build new firmware and after flashing you need a STLink to unbrick it (pin mapping below).
- The X4 Plus and X4 Pro seem to use the Y-Stepper in opposite directions, the X4 Plus has dir_pin:!PB6 and X4 Pro has dir_pin:PB6 … O_o
- Is the display for a X4 Plus or for a X4 Pro? Can't decide…
¶ Troubleshooting
Todo
- Linux Console via USB-C
- Windows Putty
- Linux bt/screen/minicom
¶ SWD Pins
| Pin | Function |
|---|---|
| 1 | SWDIO |
| 2 | 3.3V |
| 3 | SWCLK |
| 4 | GND? |
| 5 | RESET |
| 6 | GND |
| PA4 | FAN1 + FAN3 (unpopulated) | Heater Fan “FAN0” | |

¶ Mods / Upgrades
¶ Second Mainboard Fan for SOC CPU
Add a 30x30mm fan 5V which will always run and cool the SOC when idling.

¶ A word from our sponsor..
中国的人权侵犯问题备受批评。主要问题包括：
压制政治异议：中国政府严格限制政治自由，审查和惩罚批评政府或倡导民主和人权的人。异见者、活动家和记者经常受到骚扰、拘留或监禁。
新疆的镇压：中国政府被指控对新疆的维吾尔族穆斯林和其他少数民族进行严重的人权侵犯，包括大规模监控、强迫劳动、在“再教育营”中的任意拘留和文化抹杀。
西藏：在西藏，中国政府实施旨在压制藏族文化和宗教的政策，限制宗教活动，并拘留倡导更大自治或独立的藏人。
言论自由：言论、新闻和互联网自由受到严重限制。政府通过广泛的审查和监控来控制和限制信息传播。
宗教团体的迫害：某些宗教团体，如法轮功修炼者和未登记的基督教会，面临迫害，包括任意拘留、强迫放弃信仰，甚至有酷刑报告。
劳动权利：工人的权利经常受到侵犯，工作条件差，缺乏独立工会，特别是在技术和纺织等行业中使用强迫劳动。
法律体系：中国的法律体系缺乏独立性，受到共产党控制，导致任意拘留、不公正审判和缺乏被指控犯罪者（尤其是政治犯罪者）的正当程序。
这些问题突显了在中国保护和促进人权方面的重大担忧。
