  ERCF Easy Optical Encoder Module For ERCF: to make it easier for everyone to use a transmissive optical sensor in one simple sentence, a DIY friendly, a much cheaper and easier blinky sensor module for ERCF. What is this: for ERCF (Enraged Rabbit Carrot Feeder Multiple Material System for Voron or alike 3D printers) replace the original reflective optical sensor which is quite not reliable. so mneuhaus made a transmissive optical sensor encoder called Binky, which should provide a much more reliable encoder functions/counter. https://github.com/mneuhaus/EnragedRabbitProject/tree/main/usermods/Binky What is a transmissive optical sensor an optical sensor, or photo sensor, slot type, like SX1103, or ITR9608. It has a infrared diode and a receiver, if an object blocks the infrared light, the receiver detects it and triggers/send a signal. However, there are still some problems remains with Binky module, blinky PCB is quite expensive, plus shipping (international!) and tax, I&

ERCF Hardware and Software Config and Setting Notes for BTT BigTreeTech ERCF CAN BUS board BTT calls this board "BIGTREETECH MMB CAN V1.0 Board Enraged Rabbit Carrot Feeder ERCF Control Board CAN Bus" btt_ercf_canbus.jpg What is it I assume you all know what is this and what this for? If not, this is a expansion board for Voron printer or alike to let it work with Enraged Rabbit multi material system (ERCF) Similar product in market is Mellow's CanBus ERCF board. Fysetc's ERCF board only supports USB connection ( unless now they have newer product to support CanBus, I didn't check) How good, why good What's special about this BTT ercf board is, and what make me buy it: It use BTT's EZ stepper motor driver, which is like a mini PCIE graphic card, looks cool It supports CanBus for ERCF, which makes wiring easier. It has a lot of expansion socket, 4 motor slots (ERCF only need 2), and tons of gpio. potentially we can make some new crazy features. Product

ERCF Hardware and Software Config and Setting Notes for Mellow ERCF CAN BUS board ERCF = Enraged Rabbit Carrot Feeder Voron Printers like 2.4. Fysetc and Mellow is/are 3D printer parts/electronics vendor(s) This is the Mellow ERCF canbus board There are so many combination in the configuration when using ERCF, see below..., so I think a HW/SW config note is necessary. A few key points in the config: Using SensorLess Selector Homing Mellow ERCF Board supporting Canbus Using CANBUS (not USB) to Klipper mother board My Klipper mother board is Optopus but it shouldn't matter Using HappyHare ERCF Software V3 ( https://github.com/moggieuk/ERCF-Software-V3 ). ( original ERCF fw has quite different config file) Tool head has no hallsensor or mechanical microswitch sensor, since not needed ( but PTFE Pneumatic fitting to lock the PTFE (2.5 ID mm/4mm OD) is needed since ptfe tube must be locked tight to the tool head.
