    Universal G-Code Sender

    Universal G-Code Sender

    A cross-platform G-Code sender for GRBL, Smoothieware, etc.

    A full-featured gcode platform used for interfacing with advanced CNC controllers like GRBL , TinyG, g2core and Smoothieware. Universal Gcode Sender is a self-contained Java application that includes all external dependencies and can be used on most computers running Windows, MacOSX or Linux. With older versions of GRBL UGS is pretty reliable when it comes to jogging, but there are limitations. With GRBL 1.1 this is no longer the case when using the new JOG MODE syntax. This first-class jog mode guarantees the GCODE state will be unaltered and also allows you to stop a jog while it is in progress. UGS uses this new syntax automatically when it detects a version of GRBL which supports it.

    Ribbon

    Ribbon

    Ribbon is an inter process communication library

    Ribbon is a Inter Process Communication (remote procedure calls) library with built in software load balancers. The primary usage model involves REST calls with various serialization scheme support. Ribbon comprises of multiple components some of which are used in production internally and some of which were replaced by non-OSS solutions over time. This is because Netflix started moving into a more componentized architecture for RPC with a focus on single-responsibility modules. So each Ribbon component gets a different level of attention at this moment. APIs that integrate load balancing, fault tolerance, caching/batching on top of other ribbon modules and Hystrix. Load balancer APIs that can be used independently or with other modules. APIs using Eureka client to provide dynamic server list for cloud.
