+# Overview
-## connection plan
+Firmware and documentation of a custom built machine that winds and cuts cable to certain lengths.  
-See [connection-plan.pdf](connection-plan.pdf)  
+Extensive details about this project can be found on the website: [pfusch.zone/cable-length-cutter](https://pfusch.zone/cable-length-cutter)

+Photo of the built machine
+
+## Current Features
+- Measure length using rotary encoder
+- Wind to set length while start-button is pressed
+- Automatic wire cutter
+- Control interface:
+  - 2x 7-Segment display showing lengths and notifications
+  - Buzzer for acoustic notifications
+  - 4 Buttons and Potentiometer for setting the target length
+  - Reset and Cut Button
+- Stepper motor controlling a linear axis guiding the cable while winding
+- Store last axis position at shutdown
