Anyone know what could be causing this issue, first half seems perfect, but as it gets higher there are layer shifts, only slight ones, and they seem at least for a specific area to be happening like every 5 mm or so.
What kind of printer?
Rotate your Z screw by hand to see if it’s wobbling…
Its a JGAurora A5
I had noticed the table it was on had a slight wobble to it which was causing the gantry to wobble from time to time, so I took out the table and put the printer on the floor, printing again to see if that was the cause. Seems weird that a wobble would cause the errors to be so consistent though, but trying anyways.
Not printer wobble, screw wobble. Like the screw is bent… and when the X bridge reaches a certain height the screw is pushing on the gantry bearings and flexing the Z rod. Common cause of evenly-spaced ripples/ridges in prints.
K, I’m still kinda new to the 3d printer stuff, where exactly should I be looking for this screw?
@Brandon_Fennell Assuming your printer has Z screws… which almost all do… there are two, one in each column on the left and right side of the extruder. Should be next to the linear rods. Can’t see them in any convenient Google Image Search pictures though.
I’ll check it tomorrow and if need be I’ll take pics of different areas if I’m still unclear.
How are you feeding plastic from the spool? Could be a filament tension issue. Other than that, I would look at the attachment between the print and the machine. It doesn’t look like an axis shifting, more like the print and/or print head is being periodically pulled out of place.
Vibration during x,y motion. The higher the thingy the more it wobbles. Try reducing printing speed.
Or better print it horizontally.
I’ve had something like that and it was a spool of filament that was not wound very well. The filament would keep getting stuck every so often then suddenly free up.
Well either way, I’m printing it again, but I moved my printer off the wobbley table and it’s on a concrete floor now, I even tried to shake it, and nothing wobbles on it at all, so if the errors are happening in the same places then I’ll know it can’t be the wobble, or the filament itself.
I agree with @Ivan_Volosyuk as the model gets higher, I think the model itself is shaking. Try horizontally.
To verify this, you could try printing something with a sturdy base like a pyramid and seeing if that z-variation is at the same point
