Hi!
I assembled and intalled software as described here on the site.
When I use the size 3200x800px everything works fine. But the egg was only painted in the middle and not over full size.
I tested with some lines that maximum i can use 6450x1900px. If I use this size something wents wrong.
I am using 17HS19-2004S1 stepper motor and DRV8825 drivers.

How can I get bigger size without problems?

Hi
I am not sure, but I think the DRV8825 works at 1/8 steps instead of 1/16 as the A4988. That can be the source of the problem. The drawing will be halved (at least) from it original size.

Try modifying the Arduino Lines which defines the motors steps/rev:

#define initSting “EBBv13_and_above Protocol emulated by Eggduino-Firmware V1.6a”
//Rotational Stepper:
#define step1 5
#define dir1 6
#define enableRotMotor 11
#define rotMicrostep 16 //MicrostepMode (default 16)
//Pen Stepper:
#define step2 7
#define dir2 8
#define enablePenMotor 11
#define penMicrostep 16 //MicrostepMode (default 16)

Thank you.
I am now using A4988 and everything works fine.
