I don’t know what is causing this strange pattern on the sides while the front and back are good?
Y axis maybe, sticking bearings? Belt, pulleys? Loose wiring related to the y?
Check the mechanical then the electrical.
Btw does it do this on all prints?
@Jeremiah_Coley yes all now but didn’t before
Got some pictures of the machine? It’s pretty blurry in the background there. Looks like a v-slot-based Y-bed machine with multiple mods. You also have a pretty thick bowden/wire bundle that might be causing some irregularity in the movement at certain extremes.
Tighten up your X axis
Extruding is uneven or spool not unrolling smooth. Or filament diameter inkonsistent.
You may wish to orientate the object how it was printed and give the o,o point or closest point to 0,0. Then we can see what marks are related to what dimension accurately and help pin point cause faster. One thing that can be said is the marks shown that are non symmetrical would not be the cause of a belt or an object that sees the same location for the same coordinate location. For example if the mark is along x or y axis line it shows a consistent error at that point and possibly every so many mm indicating an defect with a gear. A gear belt typically is in the same position for the same grid location in the x,y and should show such linear patterns . Plastic extrusion however is not as its always changing and typically would not be pattern distortion as shown by you. Printer frame stiffness may also be an issue or loose assembly . Remember vibration may turn a tightened screw loose so check all fittings for tightness. The main patterns seem to show a gradual slipping along the 3d printed wall so you are looking for something that is gradually shifting as the wall layer builds. ensure that bearings are all in very good order and rotate smoothly ,consistently and , the frame is not loose in any way , the gears are all tightened with the screws pushed in against the flat part of the axle for non slip performance . Print a small, thin test shape in the x and then the y and finally the z to isolate each axis for faults. Obtain good x ,then move onto y and finally z one at a time. Distortion in all axis may indicate an extruder , component issue . Try Change plastic will highlight potentially faulty plastic or extruder …
@The_Kaveman I think I found it! Some gunk built up on one of the rollers face and when it would roll over it causing a bump on the side
looks not that bad, a little bit like leather.
It actually gives me an idea for a way to create interesting surfaces for some prints
Yes, you could prepare special wheels for different patterns
