Testers wanted: LinuxCNC on Dynomotion KFLOP and Kogna

Hi everyone,

We're looking for testers for a new LinuxCNC interface to Dynomotion's KFLOP (USB) and Kogna (Ethernet) motion controllers.

LinuxCNC's G-code interpreter and user interfaces (AXIS, gmoccapy) drive our third-order, jerk-limited trajectory planner (TP3), with velocity, acceleration and jerk limits per axis or per actuator. Motion execution and servo control run on the controller, so the PC needs no realtime kernel. It installs as its own LinuxCNC build in your home folder, beside any LinuxCNC you already have: LinuxCNC 2.10 built from source with four small patches, its realtime motion module replaced by a userspace one that talks to the controller. Initialization and machine functions are C programs on the controller, and a simulation mode runs without hardware.

Demo, LinuxCNC in Debian inside VirtualBox on a Windows PC:


(Please set quality to 1080p for better viewing)


Getting started: the QuickStart covers the VM, the install, the controller firmware and the first runs; on a Debian 13 PC the same install script should do it without the VM. The source is TomKerekes/KMotionX on GitHub , and FEATURES.md lists what works and what does not yet.

This is under development, and we would like to hear how it does on different machines and configurations. Please post in this thread, successes as well as problems: which controller, what you were doing, any error messages and the relevant configuration files, and install.log for installation problems.

Thanks for helping us test it!
