Despite the front panel saying "3 Axis Controller", it is 4 axis. The back panel has an "A Motor" output for the 4th axis (horizontal indexing chuck) in addition to X, Y, Z, Probe, and Spindle.
The rear label clearly has "Axis 4" checked in addition to "Spindle 300W". But it also has "INPUT 220V"! I am in the USA, I bought it from a USA importer, and it came with a power cord with a North American 110V plug. Assuming the power supply wants 220V this might explain why the power light comes on but the spindle and possibly steppers aren't doing anything.
Do you (or anyone else) know if the power supply board inside can be jumpered/adjusted from 220 to 110V? I'd still like to know if other people's controller/router combinations, regardless of model, number of axes, voltage, etc. start the fan immediately on power-up, and if spindle turns on with the switch and speed dial without any USB signal from the computer.
But I apologize for bothering the forum if in fact the wrong voltage is most of my problem. If it's not adjustable I'll have to go back and see if the not very responsive seller will exchange it for the unit I need.
