Thank You Colin & Awesome Coder for your assistance but I don't know how

Thank You Colin & Awesome Coder for your assistance but I don’t know how to implement your suggestions (I come from the antiquated analog electronic kit building days etc.) Can I start over by redownloading raspian, python 2.7 and bCNC? In other words, is there a way to redo it without having to rewrite code?
Thank You, Andrew

Yes, you can. Be sure to get all the dependence’s installed before installing bCNC

Yes from the command prompt screen, use the code awesome cider posted before.
