As mentioned above, I’ve had success using CNCJS. Performed several projects now with no issues while using Fusion 360 to generate gcode. CNCJS has a very detailed guide on how to setup on a Pi4 here → **[Raspberry Pi Setup Guide | cncjs](https://cnc.js.org/docs/rpi-setup-guide/)**

Also found a thread here on how to borrow gsender’s 3 axis probing gcode for use in CNCJS. It was posted by Heyward here → [CNCjs Probing not working](https://forum.sienci.com/t/cncjs-probing-not-working/1626)
