Post Der Kritzler using Polargraph Software

Hi!

I made the kritzler, but i can't run a program of the Kritzler, unfortunately i don't know why...

Github:
https://github.com/tinkerlog/Kritzler

this is the circuit:

Is there a way to use a PolarGraph software to drawing by kritzler?

help please!

here is the KritzlerShield arduino code:

// pin defines
#define MS1_PIN 2
#define ENABLE_PIN 3
#define MS3_PIN 4
#define SERVO_PIN 5
#define STEP_PIN_M1 6
#define DIR_PIN_M1 7
#define STEP_PIN_M2 8
#define DIR_PIN_M2 9
#define LED_PIN1 10
#define LED_PIN2 14

Hello, I'm going to trim those two posts right down to the important elements when I get home onto a proper computer. It shouldn't be a problem though. Having a quick look at the kritzler code, it seems to connect to the stepper drivers on pins 6, 7, 8 & 9, which are the same pins as the RAMPS board I think, so the changes that you've already seen on http://www.polargraph.co.uk/forum/polargraphs-group2/building-hardware-forum3/arduino-mega-2560r3-with-ramps-1-4-thread286.0.

That said, if you can't get the kritzler code running, then you won't get the polargraph code running if you use the same pin assignments. Looking at the photograph, it looks like the step and direction pins on the motor drivers are connected to pins 9, 10, 11 & 12, so that circuit is not the same as the kritzlershield circuit.
