help needed with breakout board UCNCV4

[Ger21]

DO you have the motor power supply connected to the drives?

hi, what do you mean. the wiring goes from the breakout board to the motor driver and then from the driver to the motor. what motor power supply is there needed and how does that wire into the system. michael

The drives should be powered by a separate DC power supply, typically around 48V or so. I'd need to see your drives or get a model # for more info.

Terry if you look on the 4th pic. driver out of shot on the left hand side is where the motor power goes to. there are two terminals next to the yellow wire

thanks Clive, what voltage for the driver, and do I still need a separate 5 volt input to the breakout board, or will the usb be ok.

I cannot guess the voltage what does it say on the driver or the model number at least

hi, the microstep driver is a FMD2740C . apart from adding a power supply to it is there any other wiring that needs to be put in place. also how do you find the pin numbers from the card. thanks

Ok they are 50V drives so you will need about 36 - 45 volt DC power supply.

Also the dip switches you have them set at 0.5A which is far to low.. So set sw5 to on sw6 to off sw7 to on that will give you about 3 A

Are you using mach3 or what?
Edit I see it runs off usbcnc so I think this is the manual http://www.variometrum.com/PDF/USBCNC_csatolo_ENG.pdf

shows both units

the -ve with the blue wire connected on the power supply goes to the GND on the driver next to Vin+
