For small batch production I am looking for small low cost product. Need it to be network controlled (Ethernet TCP/IP) with open documentation. The current is about 1..2..3 Ampere, voltage 24..48V. Also nice to have just 1..4 axes and DIN rail mount.
Problem is, that everything I can find is serial port controlled or modular blocks with 2-3 accessories with proprietary software and lot of unnecessary features, making software part complicated and requiring for host PC to be equipped with extra $100 I/O ports.

It looks like the Arduino Mega RepRap Pololu Carrier (RAMPS) is compatible with the Arduino Ethernet shield. The RAMPS board doesn't seem to use mega pins 50, 51, 52 and 10, which is what the shield page says it uses. I've never actually tried this myself though. The Pololu drivers can do about 1A and up to 35V.
