CNC plotter using DVD stepper motors

[abuhafss]

Hi

I am building a small CNC plotter using 2 DVD stepper motors for X and Y axis.

For driving the unit, I am using:

Main processor: Arduino Nano
H-Bridge driver: L293D
Software: BENBOX

For initial testing I wired Arduino Nano and L293Ds on breadboard as below:

For external power I am using a 5V-2A cell phone charger with customized cable.

Now, the problem is that the motors are not responding to the calibration step provided in BENBOX.
Please let me know if the wiring is correct. Any idea where am I wrong. BTW, this is my first CNC project and I took help from this video for BENBOX and the firmware

I took a chance to test my connections with sample sketch provided in Arduino Examples library. Both the motors operated perfectly which confirmed that there is some issue with "firmware laser.hex" provided with BENBOX.

Can someone recommend me some easy to use Arduino based CNC software?
