As I had mentioned in TorontoBuilders thread I needed to make a small machine to automate a repetitive job I do. I was fairly apprehensive about tackling a new programming language and have put this off for too long. Well reading all the other threads got me motivated so I bought a Genuine "Uno" a SainSmart L293D Motor Drive Shield and a couple of CanaKit nema 17 steppers, I also used a RC servo I had in my box of RC stuff. I think these will work fine for my application.
the process is
1st Step motor turns rubber feed wheel an exact amount feeding stock a specific distance.
servo motor brings down a hot wire past the end of the plastic rod and retracts, this polishes the end
2nd stepper motor brings down a razor blade and cuts the plastic rod to length and retracts.
repeat a specified number of times.
It took a couple of evenings of head scratching but I think I have proof of concept at this point. At least enough proof that I will feel comfortable making the rest of the mechanical parts.
Here is a short video of my progress.
