Soon I plan on buying either a UC400ETH or a UC300ETH-5LPT. I can't decide which one is better. Here is how I understand their feature set;
Both can controls up to 6-axis simultaneously.
Both work with the UCCNC software and Mach3.
Both go up to 400kHz step frequency operation.
Both use a Ethernet connection.
However, the UC300ETH-5LPT can also work with mach 4.
It has 49 digital inputs and 36 digital outputs in 5 IDC26 ports.
The UC300ETH-5LPT has far more I/Os. 3 additional ports with a total of 84 digital I/Os (UC400ETH only has 34 I/Os, and there are no analog I/Os)
It also has 2 analog 0-10V outputs and 2 analog inputs.
The UC300ETH-5LPT is powered by a external 5 volt power supply.
The UC400ETH is powered by a external 12 to 24 volt power supply.
My question is; why would anyone want to buy the UC400ETH when the UC300ETH-5LPT offers more features?
What am I missing?
