UC400ETH + UCSB BOB + GECKO G201X + NEMA 23 MOTOR Connection

[TheNigerian]

Hello everyone.

I wish to connect and test a UC400ETH to UCSB BOB to GECKO G201X to one NEMA 23 MOTOR; does anyone have a diagram they could share please?

I am trying to avoid any costly errors in my work.

Many thanks in advance.

hi

My diagram is shown above.

I am being careful because the NGN-USD exchange rate is murder - and I am not very sure of all of my connections.

You have no liability for any losses by expressing a view - i promise.

For completeness, I am in this position because I want to replace the bob that came pre-installed in my KT-2514 with the UCSB; it has no documentation and support. And it is possibly the reason I am not getting movement in my axes - the gecko g201(x)s have no faults and the connections are correct.

Also, I got movement in my axes in the past.

I have confirmed that my planned connections are correct - with the exception of the spare couple of wires from each motor's couple of centre taps. They are connected to the bob, and I want to know where these go on the UCSB. Although I have read that they can just be taped off, they are not taped off in his case and I want to keep everything consistent.

Many thanks in advance.

I solved it.

The bob was indeed the fault; it was broken.

I have replaced it with the UCSB bob and all three axes now move correctly. I will be adding a rotary axis this weekend.

Incidentally, I only found out today that the NEMA 23 motors are 4-wired, even though the axes' connectors to the control box are 6-pinned. the two in the middle have no electrical connections and are wired into the bob for no reason that I know.

And I have owned this router since 2006!
