The videos ( EN playlist) can move along quite fast, slowing them down (Shift-less/greater than) and backtracking (Shift-left/right arrow) may help. While the Estlcam User Manual is rather incomplete and the visuals not always up to date, there is a lot of useful information there. If the hardware isn't recognized, USB drivers may need to be installed (drivers for FTDI or WCH serial chips are the most common). Uno/Nano) and Estlcam will backup anything currently installed on the hardware. The Estcam motion control program is easy to flash onto a lot of ATmega microprocessor/GRBL compatible hardware (e.g. The Estlcam control program is free, the CAM program is free to try (becomes nagware w/ increasing wait times to generate/machine G-code) and ~$60 to buy.

While doing everything in Estlcam is the simplest and most reliable route, the programs can be used individually to generate G-code for another controller (GRBL, Mach3, etc.) or to machine ( simple) G-code generated by another CAM program (Vectric, Fusion 360, etc). Vector graphics (dxf and svg) and 3D (stl) files can be imported and machined using Estlcam (raster support is minimal). Estcam contains CAM and CNC motion control (firmware/interface) programs.
