So I recently got the SV07 as my first real printer and it’s been great until today when I’ve been getting really bad layer shifts on the X axis I just tried to print a webcam mount and it shifts almost completely off of the layer underneath I don’t know why it’s doing this and if anybody could help it would be greatly appreciated
Can you post a couple of screenshots with the model on the plate as it was printed.
Are your belts tight?
Is your nozzle tight? I once spent 3 days fighting the nozzle hooking the print and loosing counts on the X axis. Turns out the nozzle was slowly unscrewing itself. Be sure to tighten it hot.

I saw it do it this time the nozzle hit the print and and made a grinding noise also the corner of the print was peeling up but I think that might be the file that I’m printing
If your print keeps coming loose..
Wash the plate with Dawn dish soap…
Use a Brim…
Use Glue Stick..
…also what infill are you using..??
Never use the default Grid pattern, the nozzle will hit the infill & knock the print loose…
use Gyroid instead.
Petg? It ALWAYS curls some.
In addition to what Lion suggested:
Set seem location to “nearest” for functional parts reduces the travel over the infill.
Use “avoid crossing walls”
Add a “hop when retracted” value (1mm) to your filament profile (overrides tab).
I find that when printing box like parts in PETG that I get less warping the slower I print and more cooling is better than not enough.
So I tried adding glue stick, z hop, washing the build plate and brim. Im printing in PLA and I just tried to print this model BB Gun / Airsoft / Nerf target V2 by DoktorDinkel - Thingiverse and got this
check the grub screws in the sprocket for the X axis
Where are those sorry I’m new to 3d printing
Also on my SV07 the fan duct was really low so I made this
Try removing the duct. The fan is still pointed (mostly) at the nozzle without a duct
Hey I found the problem it was a slicer Issue I just deleted it and re-download it and it’s fine thank you for all the help I couldn’t do this without you
Check the wheels & rails on the X-Axis…
Make sure nothing around the extruder or the blower fan is hitting anything.
Also, a few users have put the extruder ribbon in front of the left rail, make sure you have it installed behind the rail…like in the pic posted further up.
The nozzle (or fan duct) is colliding with the print with enough force to cause something to slip.
The printer doesn’t know where the print head is. It only knows how many steps it has asked the stepper motor to make.
There are 3 places it can loose track of real position:
- The belt skips a tooth (or more)
- The motor shaft and sprocket are not “locked” together
- The torque of the motor is insufficient to move the load and fails to rotate in sync with the magnetic field created by the windings in the motor resulting in lost counts.
If in fact #3 is your issue then the next question is “why does the model get in in the way”. Short answer is “model warpage”. The long answer is too long to go into here.
Try more cooling
Try different filament (or DRY the roll you have)
Try rotating your model on the build plate by 15-30°
Avoid models with vertical “slabs” like thin wall boxes until you get past this issue
I trust Tightening the belt, but it made it worse it had multiple bad layer shifts this time
Did you ever put a hex wrench in those grub screws?
Not yet I’ll try it tonight or tomorrow
