I was worried about the blocking nature of the steppers as well as the serial comms basically fighting each other. I stopped worrying about it and only sent from Processing when Arduino said it was ready. Only problem I saw was not having an emergency stop that could restart from where it had stopped. Got over that by creating a pause button that would restart from where it had been paused and just use the Arduino's reset button for emergency stop. Then pause processing since it would be waiting for ACK from arduino it would restart at the same place or at least at the beginning of the last line. No non-blocking code needed.Quote
* cartesian bot...i need to be able to drive 3 stepper motors...able to do serial comms
Oh, you will. By the time you get it working!Quote
i dont know much about timers or interrupts
before starting any coding I went over and looked at the host software and didn't get very far. Too many classes doing tiny amounts of work. Was discouraged and said to myself "you could just write your own" That's when I looked at the stl files and had no clue how to slice them into layers and that led me to Tommelise and Forrest's Slice and Dice. If I could have hust had a look at what the packet being sent consisted of I'd been happy just receiveing it and going from there.Quote
emulating the SNAP code
I agree. It should be. All I have in my code is extruder on/off. Speed control is just pwm but reversing the motor may be necessary too.Quote
the extruder code...is going to be alot simpler
ADC is what I was planning. I wouldn't even know how to use a timer for checking the temperature.Quote
ADC and the old system is based on a timer

I can agree with what you say Zach except for #3. I think I'll stick with my way of moving the steppers instead of your non-blocking code. I didn't realize no PWM with yours!Quote

Where can I get and how much does it cost the Wiring I/O board?
The board costs US$60, shipping costs depends on volume and location, please contact hbarragan at uniandes.edu.co for payment and shipping details.
