Hi everyone,
I've been looking at various boards lately for a small CNC mill and came across the 4-axis unipolar kit from Xylotex. This board seems ideal for me, as the kit is relatively cheap (good when you're a student without a money tree...). I should be able to get it assembled successfully, even with my limited knowledge of circuit board soldering...
I have a few questions about this board though and its operation (assuming I can get one together):
- If I wanted to run stepper motors rated at 4.5V and 2.5A/phase, what kind of power supply would I need to run it? Would I need seperate supplies for the board and the motors?
- How is the current to the motors set and what is Vref?
- Does the board have inputs and outputs for things like limit switches and coolant control?
- Is it generally reliable and relatively simple to setup?
I'm sorry for all these questions, but i have to learn somewhere...
Thanks
