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....

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....

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....

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: EBB36/42 v1.0 uses STM32F072C8T6 All Pins but PA0-7, PB0-1, PC0-5, PC13-15 are 5V tolerant EBB36/42 v1.1 and v1.2 use STM32G0B1CBT6 All Pins but PA4 and PA5 are 5V tolerant As usual, crosscheck these values, I’m not responsible for any damage resulting out of this article....

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. As per the instructions of the installation of Klipper you will have to flash the microcontroller as follows: 1 2 cd ~/klipper/ make menuconfig During “make menuconfig” select the following settings: Enable extra low-level configuration options Micro-controller Architecture (STMicroelectronics STM32) Processor model (STM32F103) Bootloader offset: (28KiB bootloader) Communication Interface: (Serial (on USART1 PA10/PA9)) Once you have compiled the firmware using make you can flash it by copying the file out/klipper....

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. On different sites i then found the type of connector (Molex Microfit 3.0 2x2 connector) which is supposed to be connected as follows:

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. I finally found it here  on github: 1 2 3 _____________________ | B2 | B1 | A1 | A2 | |_ ___________ _| Or more visually (please crosscheck the colors with your extruder of choice!...

While trying to flash the klipper firmware to an Bigtreetech EBB36, i ran into the following error: 1 2 3 4 5 6 23:29:04 : Erasing memory corresponding to segment 0: 23:29:04 : Not flash Memory : No erase done 23:29:04 : File segment @0x08000000 is not 255-bytes aligned.
