DeskTop CNC 3018 - Z upgrade + SATC setup

In this video I will show how I upgraded the Z-axis on my little Cheap Desktop CNC 3018. And in the same time I made some other small upgrades, so the use of the CNC would be more easy. Especially when it comes to tool change. I call it Semi-Automated Tool change (SATC).
Also short presentation of g-code sender Candle, latest version.
