My x-axis still don´t move

I did order the X-carve and I got it just before x-mas last year
but I haven´t got it runing yet. I´m so frustrated

22

It’s the connection for the stepper motor wires at the control electronics. For the gShield it’s like this picture. The terminal blocks with four screws are where the motors connect. You can see the axis labels on the board.

23

Ok
I understand
I have checked that too, and I can´t find any wrong with the wiring

@KristianAng

Try this test, please.

At the controller (either X-controller or gShield or other) swap the wires between the X axis and the Y axis…

Connect the wires from the X axis motor to the Y axis driver at the controller.
Connect the wires from the Y axis motor to the X axis driver at the controller.

Does your problem stay the same, or does the problem move to the Y axis?

25

I´ll try that tomorrow
Right now it´s BBQ-time at the porch.
Right now the time here in West Coast of Sweden is 6pm
with Belgium beer “LEFFE”

Please come back tomorrow

Enjoy!

27

we will

Good morning Larry (my local time 10.00am)

Now I have swapped the cables as you suggested.
And it was the same result for the x-axis

When I pressed the arrow (on the computer) to the X-axis then went y-axis fine
And when I pressed the arrow (on the computer) to the y-axis, so went the x-axis as before

So the problem remains as before

@KristianAng

Good morning. Time here is about 8 AM (USA).

Put the wiring back to the way it should be.

That tells us that the X driver circuit is ok, so that is not the problem. So you either have a bad motor, a wiring error, or a mechanical binding.

With all power off, (24 volt supply off, USB cable disconnected) move the X axis back and forth manually to see if it moves smoothly or if you can feel it binding. Move it slowly so you don’t generate too much current back to the controller (you will see the green LEDs blink some if you have the gShield).

If that doesn’t show a problem then the next step would be to swap one of the Y motors for the X motor to see if it is a bad motor.

I have to work some today so I won’t be able to respond for several hours. Just post the results of your tests and I’ll pick it back up when I can.

Good morning to you
the time right now here is 2 .00 pm, and I´m watching the world chamionship hockey
Sweden just won against Norway

I´ll go out to the workshop and check it right away.
I´ll come back in a moment.

31

Please explain what mechanical bindings mean

In a few hours we shall BBQ salmon (which I have caught)
So I wont be able to write to you this evening.

32

Mechanical binding means something is physically getting stuck.

  1. With the power off can you move the X-axis with your hands?

  2. When you click the X arrow do you hear anything or see the LED on the gshield flicker?

33

Hi Zack
Thank´s for helping a stupid Swede :smiley:

Yes I can move it by hand.
When I click the x-arrow the motor trying to move forward and backwards
but it only rocking forward and back 1 - 1.5 mm

34

Did you try adjusting the current on the X-axis potentiometer moving it clockwise 1/4 turn?

35

yes sir
I did that too, erlier

36

How many turns did you do?

37

I tried 1/4 both ways

38

The way the potentiometer works is as you turn it clockwise it increases current. From the original position it was sent to you turn it 1/4 test 1/4 test until it works.

The modes of failure for your issue are:

  1. Not enough current (adjust the potentiometer)
  2. Some sort of mechanical binding or blockage
  3. The belt slipping (set screw on pulley loose or belts not tight)
  4. Vwheels too tight or too loose
  5. The motor is bad (highly unlikely but possible)
  6. The wiring is not correct or shorting
  7. The stepper driver on the gshield is bad and Inventables will replace it.
39
  1. I have done that
  2. Non (what I can see)
  3. it´s not slipping
  4. I´ve checked the vwheels, and I have set them both loose and thight them up
  5. That I don´t know
  6. The wiring is correct I have tripple checked them,
    How do you check if some of the wiring is shorting (I have a multimeter instrumen)
  7. That I don´t know

  1. You turned 1/4 turn until it the end? You are looking for the right zone. Turning it all the way up won’t work.

7 If you switch the wires on the Z and put them in the X and now the Z doesn’t work but the X does then you know that the stepper driver is the issue. If you switch it and the Z does work then your GShield is fine and it’s one of the other issues.
