I’m after some advice please guys, just had a new printer and decided to try a 0.3 nozzle. Straight lines and infill are spot on perfect but the outer perimeters are printing the shapes or triangles that make up the round sides of the object. How can I get them smoother? 0.4 head prints the same shape on another printer nice and round. Is there a setting in slicer?
IT’s a detail thing. 0.3mm-0.4mm are low detail layers. 0.2mm is the standard go to depth, and 0.1mm is for high external details. The thicker layers can also be more unstable, depending on the print infill, and material.
@Xenomorpheus he’s not talking about layer thickness, he’s talking about nozzel diameter. Idk what would cause this issue though. Other than the model itself has these waves.
Can you post the STL file? That surface looks like it should be there.
This is the same object printing right now on another printer but with a 0.4 nozzle. Almost round. I don’t get it either.missing/deleted image from Google+
This is the object before slicermissing/deleted image from Google+
Oh, sorry, didn’t get that .
I see the issue then. MOst 3D printers are defaulted to a 0.4mm extruder. So using a smaller extruder nozzle meant more plastic was spread around. If your slicer has the ability, make sure you are able to adjust it’s nozzle diameter so it can properly locate positions.
either you printing too fast for the mechanics or the mechanics is loose - check belts for tightness and make a test cylinder - print very slow for a test <20mm/s
I know the belts are ok as I rebuilt the printer last weekend. It’s like its over printing details, the triangles that make up the round base shape if you know what I mean.
Well the last print came unstuck lol but as you can see the sides are round…ish.missing/deleted image from Google+
Make sure you squish the filament with a lower layer height for the .3 nozzle. You dont want the plastic to wander before its laid down. Last print is looking better.
can you see the ripples are in the resolution of your stl ? try to print a high resolution file … or start with a cube so you have no triangles tesselation.
I started the silver print again, its almost finished. Will post the results soon.
There’s some massive overextrusion happening here either due to the slicer not having the correct nozzle diameter, or something else going on. You can see big blobs in the corners, you see piling of filament on perimeters. The perimeter here is the result of that.also…make sure you actually have perimeters turned on. I see a LOT of seams there. Moreso than there normally would be. I can’t tell exactly what is happening on this print.
A solid top infill pic might shed some light on it. Additionally, check the sturdiness of your hot end mount, make sure the hot end itself isn’t floppin’ around there.
Finished. 8 hours 30 for the 1 on the right. Needs cleaning up from the supports but the part on the left is not to bad on the round part but then has lines down the long part. Theres definitely some ghosting im sure I can fix. The print bed on this V3 is shite, I need to fix the wobble in it. Im at a bit of a loss whats causing it.missing/deleted image from Google+
Did you try increasing the resolution of your .STL file? This will make the .stl file’s tesselation triangles smaller and the surface smoother.
@Matt_Mercier how do I do that?
@Craig_Hancock It’s not the tessellation of your file that’s causing those artifacts.
What software did you use to design it?
On the right I can see the lines, but it shouldn’t be that bad. It looks like ghosting or overextrusion in the corners.
To help out please list:
What printer.
What firmware.
What slicer.
What layer height.
What print speed
What jerk/accel settings.
