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. ...

I’m an owner of a Orbiter 1.5 Extruder where there i discovered that an official filament sensor is available. Unfortunately it is a bit more tricky than with the Orbiter 2.0 Extruder. Originally i discovered the filament sensor on thingiverse  and already was about to hit the slicer when i saw in one of the comments that the files are not the latest ones. These actually can be found on the page of the author  - make sure to pick the latest files (currently version 2.2). ...

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. ...

While setting up a new board on my 3D Printer, i had the requirement to run a move of a stepper without homing first. Initially i added the following directive to the printer.cfg of klipper: 1 2 [force_move] enable_force_move: True but that didn’t help until I manually set a kinematic position through the console: 1 SET_KINEMATIC_POSITION X=10 Y=10 Z=10 Which is as per documentation  perfectly correct. Nevertheless I wanted to move without any previous checks or settings. For this I then worked through the documentation  where it actually is described correctly: ...

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). ...

Sometimes you need a special size of a grifinity box where it seems to be impossible to find the right model? Or you don’t like magnets at the bottom? Gridfinity You don’t know what Gridfinity is? Check this out: Fusion 360 Fusion 360 is a cloud-based 3D computer-aided design (CAD), computer-aided engineering (CAE), and computer-aided manufacturing (CAM) software developed by Autodesk. It is a comprehensive design and manufacturing platform that combines various tools and features into a single software package. ...

Recently i had to recompile for the Creality* Ender 3v2 (not NEO!) a new Klipper firmware based off the Klipper  0.11. ...

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. ...
