Blender with FabEx CNC add on Feb 2026

I am a long term fan of LinuxCNC and FreeCad. Unfortunately I am being forced by a client to try Blender 5.0.1 with FabEX 3.0.1 add on because they like the pretty graphics.  In 50 years of computer work I have never seen such a learning curve  non standard monster....yet nifty graphics. My problem is this: I have watched numerous tutorials, noted all the undocumented hot-key commands and slowly created a simple .blend file to machine a simple cylinder to test the gcode this thing creates. Blender Fabex will not create the toolpath; issues some error about version compatability. Do any of you folks know where I can get a SIMPLE WORKING .blend file example already setup for FabEX to do ANY kind of milling to see if can even get the application to run at all. I am VERY frustrated with Blender.  Thanks in advance.
