As someone with some EtherCat and CNC experience, what’s your interface from gcode to your CNC? Have you written custom software or is there a EtherCat compatible gcode sender I’m unaware of?

There are actually many - almost every serious (IE 100k+) wood router is ethercat.

Centroid (known for the Acorn board) released Hickory, which does ethercat servo drives but not full ethercat support. It runs the same CNC software as Acorn/et al.

Vital Systems makes an ethercat motion controller that interfaces with Mach4. They let you use any ethercat device you have an ESI file for, and map the inputs/encoders/output types to Mach4 data of various sorts (digital inputs, analog inputs, encoders, etc).

MachMotion also has an interface to Mach4, theirs is a soft realtime motion controller based on RSI's (very well known/used for robotics) motion planning.

Those are the more standard ones.

Twincat also has an NC interface that supports gcode but you'd have to make your own UI.

LinuxCNC can do ethercat, but i've never considered it :)

There are also more standard hardware solutions. Syntec's hardware controller can do ethercat, etc.
