3D printing trouble

[R3tr0j]

I would love to know why are some of my 3D prints slanting like this not all of them are doing that but it seems when I try to do specific prints it just keeps going towards one side like this. Any help is appreciated because this is driving me nuts. I attached a picture for a better example.

Classic layer shift. Try slowing it down.

 

I assume that you run it fast due to the very extensive ringing.

Yea I’ve been running it at 100, what should I run it at?

@R3tr0j That's 100%? See the waves after the sharp edge in the print? This is called ghosting and shouldn't look like this at stock settings. 

Dd you modified the acceleration?

 

Assuming it's all stock/default: Turn the printer off and move the carriage by hand. Does it binds up (excessive force required)? If not adjust the stepper driver current for the x-axis and just the x-axis (look up the procedure). With this done start a print and check that the issue is gone. Last but not least measure the temperature of the stepper driver to make sure it isn't overheating (or causing long term damage to the PCB due to high temperature).

 

edit: maybe check the belt tension as well before changing the stepper driver current. A loose belt shouldn't cause layer shift but the ghosting shouldn't be this significant (even through the visible ghosting is from the y-axis and not x-axis).

Sorry yea I meant 100% and I changed the default 0.4mm nozzle to a 0.5mm and alright I’ll try that out thanks!

Other than the nozzle I haven’t changed any of the settings definitely not the acceleration 

[FlyingPotato_is_taken]

Nozzle change shouldn't cause this.

 

one more thing: Since increasing the stepper driver current is the last thing you want to touch I would also make sure the pully on the stepper driver is tight . Finger tight is good enough. Don't over torque the tiny screw! 

Could be that there isn't a screw on creality machines (heat shrink/press fit). Slowly move the carriage in both directions (by hand) and observe if the axel of the stepper driver is rotating without significant play/backslash.
