X- axis shift

I am having a problem where my prints are shifting in the x direction. I've seen a few good topics covering Y shift here and here.
I assume it is probably a similar problem to those suggested in other threads,

Loose set screw on the stepper motor
Belt is not tight enough
Some cable is loose
Some cable is catching
Not enough power to the stepper motors.

I know the belt is pretty tight but I will check this and these other things when I get back home.
Does anyone have any particular thoughts about this problem on the X axis?
Or any Ideas based on the fact that it happened many times during the print. Here is a picture to see what I mean.

Thanks

Hi Kenny

First thing to do is to ensure that you have the latest firmware loaded and select the "High Power" setting. Printer will be noisier, but at least you will rule out power issues.

Hi Peter and Kenny,

I have the same issues when printing detailed print specially when i print the maker bolt . updated the firmware prints seem to be better but still same issue. checked the belts and pull they all seem very tight.

I'm sure am missing something but don't know what.

Re: X- axis shift

To be honest, if we are talking about banding rather than shifts (where one axis shifts several millimetres and does not recover), then there are many potential causes.

Firstly, you need to calibrate the filament feed, check the filament diameter (some cheaper filaments vary considerably across the length of a roll) and quality and even how the filament is stored.

Then you would need to compare with different slicers; some are much better than others at producing a specific model.

Try cleaning the nozzle, possibly replace the PTFE tubing. Verify the nozzle temperature, increase temps a few degrees. Decrease temps a few degrees (an over-heated nozzle can produce worse results than one under temps).

After that, look at the overall build quality, including cable routing (cables may be catching at certain heights); watch the printing closely (or video it) to see if there is any possible cause.

To get a printer is working well and producing great models can be very difficult if there is just one thing that isn't quite right.

Re: X- axis shift

One other thought - are the cable ties holding the bearings in place tight enough?

Ok so it seems like it was a power issue. After switching into High power mode I haven't had the problem for my last few prints. Still I will keep an eye out for the next few weeks to see if it happens again
