Firstly, I would like to mention a little bit about the project background then I will list my questions. Any help is appreciated
Background: I am an undergraduate mechanical eng. student and I have a project that requires me to build a CNC milling machine with an automatic tool changer. The axes ranges are both 1 meter in x and y directions, and it will be used to machine polymers. I am planning to use Ramps 1.4 for the control card and I am also planning to use LCD to stream the G-codes with an SD card.
Questions:
1) Since I will be using the Ramps 1.4 for CNC milling operations, which CAM software do I need to use to generate the appropriate G-codes. And in what extension these G-code file should be?
2) How do I connect the spindle to the system and how can I control the rotation speed? Do I need to by additional equipment(s)?
3) Since the axes ranges are relatively long I will use the Nema 23 steppers with an appropriate motor drivers. Can I connect these drivers, with capable power supply of course, without any problem?
4) Is there any utility slots in Ramps for me to integrate the automatic tool changer once I figured out how the tool changer would be?
5) Do I need to change anything in Marlin software to use it for milling operations?
6) Any additional advices?
Thank you for your help!
