### Basic Information: Printer Model: Anycubic Chiron MCU / Printerboard: BTT SKR Mini E3 V3 Host / SBC: Raspberry Pi Zero 2W klippy.log: not applicable This post is a followup to [my first post](https://klipper.discourse.group/t/unable-to-read-tmc-uart-stepper-x-register-ifcnt/20359) about Klipperizing my Anycubic Chiron. In that post @mykepredko recommended I switch from the stock Trigorilla board to a BTT SKR Mini E3 V3. After following that advice I am now at another roadblock while attempting to connect all the wires from the Chiron to the SKR mini. ![jAxLJTv](https://global.discourse-cdn.com/free1/uploads/klipper/original/3X/e/a/ea8e5615e2418d0e552a905bc2add89f8a949892.png) SKR Mini E3 V3 wiring diagram Overview of what I’ve attached so far. Powers on w/o exploding. ### Issues: In no particular order, the issues are as follows: - Z-stop sensors are 3-wire, but SKR mini only has a single 2-wire connection spot: - SKR mini bed heater (H1) seems designed for switching full power of the bed heater, but the Chiron has a separate relay board for controlling the bed heater: - Chiron bundles the hot end heater, hot end thermostat, X-stop, & homing sensor through a 8-wire cable. SKR mini (reasonably) expects these to be separate connectors: - Chiron LCD uses proprietary 5-wire connector. SKR mini does not appear to support this unit & everyone online suggests replacing w/ BTT TFT35. For my purposes the touch screen is low priority, so I’m skipping this for now. I am not sure how to go about diagnosing or otherwise finding the answers to these issues. Search results have been unfruitful, but I doubt I’m the first person to attempt attaching a Chiron to a BTT SKR Mini. Cheers ---

Apparently “new users can only put one embedded media item in a post” so I’ll have to break this out ---

- SKR mini bed heater (H1) seems designed for switching full power of the bed heater, but the Chiron has a separate relay board for controlling the bed heater: NOTE: control wire is the 2-wire connector right by my finger in the pic ![2025-01-29-15-06-55-647](https://global.discourse-cdn.com/free1/uploads/klipper/original/3X/4/6/4689b07cc557d449a26b99b9a212c54086b6f429.jpeg) ---

Another view of the heater relay control board. Control wire is to the left in this pic. Large wires to the right are from power supply unit. ![2025-01-29-15-07-15-810](https://global.discourse-cdn.com/free1/uploads/klipper/original/3X/3/e/3e78ee63e24a1593059ad5a7d1d48b7cbc2e1eb2.jpeg) ---

Chiron bundles the hot end heater, hot end thermostat, X-stop, & homing sensor through a 8-wire cable. SKR mini (reasonably) expects these to be separate connectors: ![2025-01-29-15-07-48-052](https://global.discourse-cdn.com/free1/uploads/klipper/original/3X/9/7/97468a98fb9a8bc8ece0e89d88a7ff6c52528449.jpeg) ---
