A5 Gearbest 2500 Y axis motors run opposite direction
« on: August 30, 2016, 12:22:26 PM »
I got my Gearsbest A5 unit and quickly assembled and plugged this thing in running the benbox software. I think I have everything correct, it try's to work, it burns wood and X moves well but when making Y movements it appears as it wants to rotate. The wiring harnesses are not identical to the 2 Y-axis motors, one set appears to have a different orientation of the wiring, but I assumed this necessary for one to run CW and the other CCW.

Wanted to know if I missed something, should attempt to reverse a coil/winding(Which one?) or if there is a software setting to adjust??

Welcome to the forum!

Do you know which controller board you have? If you could post a picture of the controller board showing the connections, that would help.

I believe it's the NanoLX (It's at home, I'm at work) Thats the driver and settings I used to get it to kind of work...

 the "wiring" to make the y motors run opposite is on the board, not the cables. The connector farthest right is the X motor (axis). The two 4pin connectors in the center are the Y motors.

Make sure your cables are plugged all the way in. Make sure one side is not dragging against something. Test each motor alone to see if both motors are working.

If one does have the wires backwards in the connector you can move them to the right places. You need a needle to lift the tabs then pull the wires out. Then put them back in the right way.

If they were assembled wrong you should be able to fix it pretty easily.

Thanks LOB0426, I haven't tried it yet, but if you are correct and the Nano drives them opposite each other, then it should be the cable, one is obviously wired in a different order from the other Y-Axis. Or perhaps I should have used the cable going to the X-axis??? you know the directions are wonderful.

I won't have time to play with it until this weekend. So I'll update you then...

The key to this problem is that the two motors drive in opposite directions.  To reverse the direction of travel, simply swap the cables at the controller.  If you mounted the board with the connectors pointing down, the Y axis cables must cross each other to reach the correct sockets.  Your discussion helped me see that this was what was wrong with mine, so I'm here to return the favor.

Regards,
Jeff

FWIW, I think I swapped the direction on my y axis in the GRBL setup.  I'm thinking that only works per axis though.

You can swap axis direction but since the Eleks board uses a single driver for the 2 Y-motors you can't fix it with software, it has to be a cable issue.

you can switch the direction from one moter by switching the wire one and tree on the motor now it turns to the other way

Swapping 2 wires corrected the issue. I couldn't decide which Y motor to swap the colors on, so I decided to match the x-axis wiring and make them all the same. The machine seems to work well now after toying with some settings I got some good results. The only thing I was hoping to do is do Text outline instead and the Ironman sample file only output a big black rectangle.


(Photo shows the wiring before I fixed it and how it came from the factory)

All of mine are wired the same color code.

@dblaser Happy to hear you resolved the problem, hopefully just a one off incorrectly made cable.


All of mine are wired the same color code.

As they should be.
