For some applications (like when you want to connect the BIGTREETECH E3EZ* ) you might want to increase the timeout for the shutdown of the BIGTREETECH Relay 1.2* . Especially in the case of the E3EZ the issue is that the power of the PSU is also the power for the Onboard CPU (e.g. CB1* or CM4). So when this power cuts too fast, the PSU would be switched off before the CPU has shutdown. Lastly you might want to be able to start the relay through the pins (and not just shut it down) instead of resetting the device. ...

When i started using the BIGTREETECH CB1* on the BIGTREETECH E3EZ* i quickly got into the trouble of mapping all the pin descriptions to gpio numbers. Luckily i’m not alone and i found a solution here  . ...

When i started using the BIGTREETECH CB1* i noticed that the system time was almost always wrong. Solution There are different solutions for this but the following one worked the best for me: First remove NTP: 1 sudo apt remove ntp and install the systemd-native timesync service: 1 sudo apt install systemd-timesyncd This should automatically install the service and start it. To make sure, you can check that systemd-timesyncd.service is active (running): ...

When i received the BIGTREETECH E3EZ* together with a CB1* i was wondering how the pinout / gpio on the board was setup. Unfortunately the picture in the User-Manual of the E3EZ was relatively blurry. GPIO stands for General-Purpose Input/Output. It refers to the pins on a microcontroller or single-board computer, like the Raspberry Pi, that can be programmed to serve as either inputs or outputs. These pins enable the device to interact with the external world by receiving or transmitting digital signals. Through software programming, developers can configure GPIO pins to read data from sensors (inputs) or send signals to actuators (outputs), facilitating versatile applications like the control of fans, lights or other 3D printing accessories. ...

Recently i was looking for a guide which pins on the BIGTREETECH EBB36* can be used for 5V applications. After a bit of digging, i came across this forum entry  where it was described that the following pins are 5V tolerant: ...

If you ask yourself which voltage the fan connectors of the BIGTREETECH E3EZ* board have, you are not alone. The User Manual of the BIGTREETECH E3EZ Board just features a “Mainboard Supply Voltage” description but not special “Fan Voltage”. And this is on purpose - basically the fan features the same voltage as DC_IN. So if your Mainboard is connected to 12V, the fans also should be 12V fans. And likewise with 24V (which is a bit more common). ...

When i received the EBB36* of BIGTREETECH i slowly built up all the connections towards my existing hardware of the Ender 3v2. One information that was missing was the can bus connector details (e.g. type and pinout). The manual  unfortunately doesn’t show the details. You could derive it from the schematics  but still isn’t very visual. ...

When i received the EBB36* of BIGTREETECH i slowly built up all the connections towards my existing hardware of the Ender 3v2. One information that was missing was the stepper pinout. The manual  specifies the port as “E-Motor” but doesn’t show the details. You could derive it from the schematics  but still isn’t very visual. ...
