I retired in 2018 😃 after working for a major British oil company for 39yrs, working at their research facility testing cars & motorbikes exhaust emissions, the vehicles being driven by robots in a very controlled facility. Having worked with very sophisticated (and expensive!) systems, I fully understand the challenges and frustrations of working with 'robotic' control. (Even the best systems rely on that variable that is human input - a dot instead of a comma leads to very unpredictable results 🤥!) .
I love woodwork, (traditional and modern) and now want the challenge of building a CNC router, I will spend the next few weeks (months?) reading and gleaning information from this site before taking the plunge, so please be patient with what will be initially (and maybe always! ) stupid questions 🙄.
