Hello again. I'm testing my boards and configuration before I install everything on the real machine.
I'm configuring a lathe with 2 servos for the X and Z axis, one PWM converted to analog for the spindle, and one encoder input for the spindle. Also a lot of input and outputs to deal with. For that I purchased a 6i24 with a 7i44 to drive one 7i70 and a 7i71 for inputs and outputs. In adition to that I originally planned to use a 7i33 to drive the servos and spindle with analog voltage and also read the encoders coupled to the screws and the one on the spindle. I changed my mind and I plan to use step + dir to drive the servos and leave the rest as it was originally planned. So I guess I need another daughter card to drive the servos via step + dir. >From what I read the ideal board would be the 7i47 but I needed to ask here first. Also I'm having a little bit of trouble finding the right firmware for this kind of setup. To sum up: ---- 7i70 ---->Relays / ----> 7i44 -----> 7i71 <-----Sensors, buttons, etc... / 6i24 ----> 7i33 <----> Spindle analog out/ Spindle encoder in \ ----> 7i47 ----> Servos step+dir output Please let me know if this is the right approach and also guide to find the right firmware because I'm not sure wich one I can use. Thanks as always and sorry for the long post.
