ioSender is a Windows control program written by the grblHAL developer for CNC machines with Grbl or grblHAL controllers. It shows the program in 3D with a live tool marker, jogs up to nine axes, runs probing operations and offers advanced controller configuration with on-screen documentation. A lathe mode adds conversational programming, and threading is available with a grblHAL controller that supports spindle sync. Network connections are supported too. Limitation: Windows only, and some features need grblHAL rather than plain Grbl.
