I managed to get things working on my breadboard (or so I thought), so I soldered up two identical circuits on an Arduino shield, popped it onto the Arduino, and nothing worked. This led me back to the breadboard where I discovered the driver chips were getting very hot and shutting down. The motors do rotate, but their direction is sporadic, especially under load. I have everything hooked up theby riccirich - Controllers
heres how I have the pins set up: DIR - DIO7 STEP - DIO6 SLEEP +5v RESET +5v MS3 +5v MS2 +5v MS1 +5v and ground through a 100k resistor ENABLE - DIO8 (active low) VMOTR - +19v and PS ground through 100uf cap GND - Arduino Ground pin 2B - Motor 2A - Motor 1A - Motor 1B - Motor VDD - Arduino 5v pin GND - Arduino Ground pin hope this helpsby riccirich - Controllers
If you build a reprap from a kit, you can expect to spend a considerable amount of time getting things keyed in right. It took me about a week after completing mine to finally get to a point where I was getting consistent results, the most critical factors in achieving this being a completely level print surface, an accurate extrusion width over hight ratio, and proper hot-end temperature. All ofby riccirich - Reprappers
so in the arduino IDE it would be like pin1(low)? what is th voltage i should be reading on the pin?by riccirich - Reprappers
everything seems to be working. the Direction pin has +5v on it, and the step pin jumps from 0 to .3v when I tell pronterface to move the x axis. What should the enable pin be reading?by riccirich - Controllers
Hello all. I am currently working on a cartesian plotter which I am controlling via an arduino UNO loaded with a modified version of the Teacup firmware. Everything has been going smoothly until I tried interfacing with StepStick drivers. I know the driver works because I swapped it out with one on my sanguinololu and it worked normally. I have Teacup firmware flashed onto my arduino with digitalby riccirich - Controllers
I am also trying to get an arduino (UNO) to interface with a stepstick but to no avail. I know the driver works because I swapped it out with one on my sanguinololu and it worked normally. I have Teacup firmware flashed onto my arduino with digital pins 5, 6, and 7 connected to enable, step and direction, in that order. I also have both grounds connected to the arduino GND pin and vdd hooked up tby riccirich - Reprappers
