SHT36 T1 Configuration Example

This is an example tool configuration file for T1 (Tool 1) using an SHT36 toolhead board, compatible with klipper-toolchanger-easy.

Example Only

This is an example only. Copy the configuration below to stealthchanger/tools/T1.cfg and customize with your values. DO NOT use this file directly.

Pin names may vary between SHT36 board revisions. Verify pin assignments against your board's documentation or schematic.

T1+ use numbered extruders (extruder1, extruder2, etc.). Only T0 uses extruder without a number.
