Problems with axis movement

Anthony_Contreras_SW · August 26, 2017, 11:30pm

After wiring and configuring my new smoothieboard, I am getting some odd results.
I am using a 4x. (ordered a 4xM and received a 4xC in the mail, odd I know)

Moving the X or Y axis results in very odd movements. The steps are extremely noticeable, and the movement even shake the entire printer.

My Z axis seems to be working fine however, and when I swap the X and Y morots onto the Z drivers, they seem to work fine as well.

Requesting the printer to move along the y axis in the same direction also causes it to backtrack, It appears to take a few steps forwards, and then a few backwards. Requesting bigger movements (100mm) results in a shaky movement all the way through. Requesting the exact same movement in the same direction then sometimes flips direction on its own.

I have tried formatting the SD card, as well as uploading a default config file, and same errors appear.

I don’t believe that any of the motors are wired incorrectly, as they work fine when swapping to other drivers.

Any help would be appreciated thanks!

Here is my current configuration:

This sounds like only 3 of the 4 wires of your motor are getting to the driver, I would check/re-do the crimping of the connectors.

Anthony_Contreras_SW · August 28, 2017, 10:17am

I don’t think that is the case. I have swapped motors to other drivers, and they seem to work fine using the same wires.
For instance, my Z steppers work very nicely.
So when I swap the Z and X, the x now works, and the Z steppers become funky.

If it helps, my Z steppers are wired together at the connector terminal.
Thanks!

Arthur_Wolf · August 28, 2017, 3:37pm

On X and Y, does it still move the right distance and the right direction ?

Anthony_Contreras_SW · August 28, 2017, 8:52pm

Yes, even with the jerk like motion, it seems to move the right distance, direction on the other hand is a mystery.
I have a short video of my printer in action atm, but can’t seem to post it due to being a new user. I’m going to send it to you in a PM.
Speakers or headphones are a must. (If anyone else would like to take a look at the vid, please let me know, and I’ll PM you a link as well)

In the video I requested 3 movements, all being in the same direction. (spoiler, it moves forwards, and then backwards)
