Strange problem when saving data to SD card

I am using an Arduino Mega 2560 equivalent controller to read a G-code file received by an Xbee on serial port 2. The file needs to be saved onto an SD card until the machine is ready to process the data.

For this test I am using the Tera Term VT software to send and receive data over the Xbee modules on serial port 2 and the USB cable to upload code and debug. The code was written using Arduino 1.0.6 but i have also tested in Arduino 1.0.4 with the same results.

How to build a delta 3d printer?

Dear: LMR

Hello LMR it is me Noah again. You should know for the past few weeks I have been trying to make a 3d printer. I have given up on my original designs. You see I had an idea for a 3d printer that was too diffucult for me to build which was a soft robot arm 3d printer but it was a failure. Now I have decided to build a delta 3d printer and this is what I am trying to ask you.

UDP not working with static IP-address @ WiFi-shield

I use a WiFi-shield (firmware 1.1.0) in conjunction with an Uno R3 and IDE 1.0.5 r2.

If I use DHCP for assign an IP-address to the shield the Arduino UDP NTP-example works fine.

If I set a static IP-address (Wifi.config) I stop receiving UDP packets from the NTP-server.

Any ideas?
