Axis are studdering.

[franazzo]

The X-Axis is hopping back and forth for about 1/16".
The Z Axis is working up and down but with a "studdering" movement. _____ - - _____ - - _____ - -
The Y 1 and Y2 Axis is also working but with much more "studdering" movement, approx. every 3-4 inches.

I am attaching pictures I took from Shapeoko.com/electronics and compared those with the setup of my machine and it doesn't look quite the same and I would like to know why or if this would make a difference.

Picture #1 is MY SETUP of machine.
Picture #2 are the pictures taken from Shapeoko.com/electronics

My colors don't match their image either - they match yours. However all my red wires are on the same side of the block - far right pin (A1). Mine is not done and in use but it seems to be jogging okay.

This is weird.

My machine, reading from left-right, looking over the top of the gantry so that the lettering is right-reading:

Z-axis --- blue, black, green, red
Y1-axis --- blue, black, green, red
Y2-axis --- blue, black, green, red
X-axis --- blue, black, green, red

(Not only did I look at my machine this time, I even took a (lousy) picture):



If your machine's wiring doesn't match that image, contact support@carbide3d.com

Ignore the wiring diagram from the Wiki, that's for a Shapeoko 2 with gShield.

The first thing to try if your motors aren't working well is to turn the power off, then move all the switches on the board back and forth a few times. Remember to return them to their original position. If that doesn't work, I'm out of ideas, but it helped at least one person.

Hi Will,The wiring on my unit is different from your picture!
You think I should get in touch with carbide?
Your picture shows:
Z axis------blue.black,green,red
Y1 axis------blue.black,green,red
Y2 axis------blue.black,green,red
X axis-------blue.black,green,red

My wiring are:
Z axis------blue,black,green,red
Y1 axis----red,green,black,blue
Y2 axis----red,green,black,blue
X axis-----blue,black,green,red

That does not make any difference. The way the connectors are wired, reversing the order of the wires still works, and turns the motor in the same direction. Both wirings are correct.

Sorry, I am not quite sure what you mean with " move all the switches on the board back and forth a few times", you mean unplug the wires and plug it back in again?

There are DIP switches on the board which allow one to select NEMA17 or 23 motors or 1/4 or 1/8th microstepping.

They should be labelled.

I found the switches, they are all on 1/8th.

[cvoinescu]

Yes, they are, but that's not my point. With the power off, move the switches back and forth to clean the contacts. Do that for all eight of them. We've seen one case when a N17/N23 switch caused a motor to make a crackling noise, meaning the switch did not make perfect contact; toggling the switch a few times cleaned it, and the noise was gone.
