smooth layer shifting on ender 5 (y axis)
I have had an Ender 5 for about 2 months, I have had no problems with it so far. Since 3 weeks I have installed the Silent Board V4.2.7. And also had no problems.
When printing elements with about 4cm in the Y axis I get a layer shifting. The higher the layer, the more it moves to the back.
What I have done so far:
– I printed a Qube, 2x2x2 cm. Central on the print bed, 60mm/s, no problem.
– I printed a Qube, 4x4x4 cm. Further back on the print bed 60mm/s. I get slight offset.
– And here something bigger (see picture) here the offset is clearly visible.
Action I have taken:
– i leveled the bed again
– recalibrated the extrude
– i cleaned and tightened the belts and screws.
– Speed greatly reduced (30 mm/s) so the misalignment is less. But printing is very slow.
– I measured the voltage of the stepper motors and first set them according to this information: https://support.th3dstudio.com/hc/product-information/3rd-party-control-boards/creality-boards/creality-v4-2-x-tmc-boards-recommended-vref/
– But after it did not help, I set the voltage like this:
X 1.20v / Y 1.15v / Z as before / E as before
My print settings:
PLA / 200°C / 0.6mm nozzle / 0.3mm layer height / 0.2mm line width
I hope I have not forgotten anything and would be very grateful for your help.
Please excuse my English 🙂
@alfred0815 Your situation brings me back to the layer shifting issue of Ender 3V2. Eventually, they concluded that it was a static electricity problem. Actually, it is the mainboard issue, which the static protection on the mainboard is not well done.
Please get a try if you are interested in finding the issue.
@kevin Thanks for your tip.
In the meantime, I’ve gradually increased the voltage of the Y motor to 1.33v and it seems to have solved the problem – I’ve done some test prints without shifting.
I will print the same as in my first post today/tonight 😀 to see if it really got better.
@alfred0815 Just got feedback from Creality Tech. The voltage of the XYZ axis motor driver is all 1.1V. So please refer to this if the issue still there when you finished the test.
Thanks for the Information.
When the Y motor voltage was at 1.15v, I had shiftings. So I thing 1.1v for Y Motor will also produces shiftings. A small print test with 1.33v on the Y motor had no more shiftings. So this change definitely helped.
I will try the Print with 1.33v today and report back.

Shifting does not seem to be an isolated case
@kevin I still had shifting problems with higher voltage value for Y axis. I changed the Board to original board of Ender 5, but I still get layer shifting for long y movements.
I grounded the y motor to avoid static electricity problem, no success.
so I don’t know what I habe to do next.
@alfred0815 I would like to check the Motor: Test the resistance of the motor pins, the red arrow, and blue arrows point to the resistance of the two pairs of pins, if the difference is large, the motor has problems.
I checked the resistance:
1 and 4: 2.9ohm
3 and 6: 3ohm
I think this difference is not big. What do you think?
@alfred0815 Yep. It is not big.
Wait. I think your shift is on X-axis, instead of Y. Am I right? See your picture in the first post.
the shift is happens, when the y axis motor runs back and forth.

Should I swap the x and y motor cables and see if the shift continues to happen on the y axis or goes over to the x axis?
@alfred0815 To swap the x and y motor cables is a good way to check that if the issue is caused by the motor. Go ahead please!
I swapped the x y motors and min switches, I still get shiftings in same direction as before.
So I think the y motor has a problem.
@kevin my last print was a catastrophe.
it will not get better.
@alfred0815 Can not agree more. But the wired thing is the resistance of the motor is right. I can only think maybe your belt has something wrong and we all overlooked it.
@kevin I made the belts looser. I have made them tighter. Does not help.
Unfortunately, I do not know how to proceed.
I have written to creality store but have not received a reply for three days. I wrote to them on facebook, no reply either.
I have now ordered a new Y motor. I will then test it.
