*I am unsure how much data the arduino can handle. I plan on sending a pair of integer numbers (4 bytes each) 60 times per second, so 240 bytes/sec. I believe (could be wrong) the arduino can only handle 9600 baud which is something like 150 bytes/sec. I believe a workaround would be to use 16 bit ints, which would drop that to 120 bytes/sec and still maintain an accuracy higher than the stepper would need.
This is the least of your worries - the Arduino can manage 115200 baud easily and people have run it faster sucessfully.
Thanks for mentioning my Stepper library! Can't wait to see how your project turns out. Will you post a video when it is working?
Hello.Could you show more photos of your stepper mounts with each other ?I try to make similar device but wonder how to mount this steppers to kind of pan-tilt system.Also very interesting how to solve problem with limits rotation shaft ?I need to rotate shaft from 0 to 180 or may be more but if it not going round and tear my cables.What kind of limit do you use ?
Thank you ! I'll wait for pics.
Thank you !Looks like you didn't care about limits rotation shaft ?How you solve the problem that cable from laser and from second motor (one that with laser) can be going round and torn ?Did you use some limits in your program code ?
