Re: Closed loop vs. stepper motors -advice sought - 7 years ago
So, I've decided to go down the path of stepper motors at the moment just to get my machine up and running. I'll use C5 ball screws for now and see how it behaves and then make improvements along the way. I'm still keen on the idea of linear encoders and will look at that later on down the track. Thank you for all the replies to my question. Mikeby jappiemike - Mechanics

Hello Gents, I'm sorry for not being more active on this questions but I'm working 14 hour days on a mining site and apart from work eat and sleep I've not got a lot of spare time. I've not read the whole of Ben's thesis but I will get to it soon. I initially thought all i needed to do was alter the axis moving function in the Gcode library and the linear distance reading would "bubble" through tby jappiemike - Mechanics

Hello gents and thanks for the feedback so far. VDX, which software/firmware are you using, I'm a mac man, so I would like to stay away from Windows if I can. Cheers Mikeby jappiemike - Mechanics
Closed loop vs. stepper motors -advice sought - 8 years ago
Hello gentlemen, I have been thinking of my next Arduino/Mbed project and a 3d printer/router/SLS/powder printer seems the go. I've been thinking of building a 500mx500mm welded steel (50x25mm sections) bed machine and using linear encoders along the X and Y axis to give me the accuracy that C7 ballscrews apparently won't. When using encoders why do you use quadrature code when you already knowby jappiemike - Mechanics
