EBB 36 CAN Control Board with MAX31865 Converter CAN Bus Support Precise Control of Feed Head PT100 PT1000 Temperature Sensors
This version of the EBB 36 CAN board is enhanced with the MAX31865 converter, which allows for very precise measurement of PT100 and PT1000 temperature sensors. The MAX31865 converter converts the resistance signal from these sensors into a digital value, providing reliable temperature data for controlling the feed head and other parts of the printer. The foundation of the board is the CAN bus, which is a communication system allowing for fast, stable, and secure data exchange even over longer distances. The integrated measurement chip ADXL345 is used to monitor vibrations during movement and helps to limit undesirable resonances. For controlling the feed head motor, the TMC2209 module is used, ensuring quiet, precise, and smooth operation. The board includes protective elements against electrostatic discharge and overvoltage to ensure long life and safe operation. Connectors are labelled for easy connection of motors, fans, sensors, switches, and lighting elements. It is also possible to enable the 120R termination resistor, which may be required depending on the length of the CAN bus wiring. Power can be selected via USB using a jumper, which is convenient for setting or tuning parameters.

Installation Instructions:
The board can be mounted on the motor controlling the feed head using standard screws. First, connect the CAN bus and choose whether to activate the 120R termination resistor. Then connect the power, motor, fans, switches, and temperature sensors. The MAX31865 converter ensures precise reading of PT100 and PT1000 sensors, which are connected according to the type of resistance wiring. If power via USB is necessary, the jumper is set to the appropriate position. For measuring vibrations, the ADXL345 chip is connected via a data cable to the main board of the printer. In the Klipper system, CAN communication is then configured and the appropriate parameters are set.
This variant of the board is designed for more demanding users who require precise temperature measurement and stable control of the feed head. The MAX31865 converter significantly improves the quality of temperature regulation, which is important when printing materials that require precise temperature stability. The board simplifies cabling, increases system reliability, and provides features that standard motherboards do not offer. It is suitable for upgrading older models as well as for new constructions where high accuracy and professional results are required. It offers easy installation, high compatibility, and reliable technical solutions for long-term use.
