Feedback on My Youtube Videos 🇬🇧

I have a small youtube channel. I am a noob to CNCing/3d printing. I decided to record some of my build and make some tutorials. Just pretty basic stuff. Could I get some feedback. Not just on the quality but also content. 

Please let me know what you do like and what you don't like about them. Since I am still a noob to this world myself the topics aren't super advance. I made a playlist of just the CNC stuff so you don't have to go through all the electronics repair videos https://www.youtube.com/playlist?list=PLZ7ip3DGZF43D9ci8XyKyBpiCrfcGPbPh

Thanks in advance.
