wifi

i wonder if can possibly adapt this to the rambo and make it wifi.

Knowing you, I'm sure you can get it working as wifi. I would be extremely concerned about walking away from a print
that is going to take awhile. There is so much RF in our environment from all the different devices we use that to rely
on wireless signals to control anything of such importance is a scary thought. I think the question is not if we can do
it, it is if we should do it.

or maybe set it up, so you could load files to the sdcard on the printer and just use the wifi to control it. it wouldn't be actually printing from the computer through wifi.

im no software guru, so i dont know if this is possible.

You need to get one of the arduino wifi adapters, they aren'y overly cheap, but not ridiculously expensive either, they usually connect to the SPI pins, which are currently connected to the SD card reader. They should both work together you just need a different CS line.
Then you need to fix the software chain to support it, here is someone doing it here

The speeds will be limited by the SPI interface.

IMO the biggest issue is the lack of RAM on the ATMega, to deal with the latency issues, it doesn't give you a lot of leeway for a poor connection.

The thing that always put me off the idea though was when you look at the datasheets on the Wifi boards they all contain processors that are 5-10x faster than the ATMega is and it just feels wrong to me. The ATMega is used because they are in wide use with software support, not because they are well suite to the job, the difference in cost to produce a board with a 16MHz ATMega and a 160MHz ARM chip is < $5. Use an ARM chip for the electronics communicate over ethernet, use a wifi bridge if that's what you want.
