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
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
