01/ Problem
Problem
Drive a dual-gantry 6-axis CNC from a Klipper-style host so the planner gets sub-millimeter accuracy without paying the Mach3 / LinuxCNC tax on every reconfig.

Dual-Gantry 6-Axis CNC
A Klipper-for-CNC fork running synchronized gantries.
- Klipper
- Python
- Custom firmware
- G-code
- LinuxCNC
02/ Approach
Approach
Fork Klipper to support synchronized dual gantries on the same logical X axis, add 6-axis kinematics, expose toolpath calibration through the host. Write supporting Python tooling for offline trajectory diff and dry-run.
03/ Hardware
Hardware
Two synchronized stepper-driven gantries. Custom MCU firmware. Standard CNC tooling.
04/ Result
Result
Working tool path execution at sub-mm precision. Supersedes a vendor stack that did not handle dual-gantry sync cleanly.
