How do you stop warping with PETG?
Lower the print speed and nozzle temperature. Printing at a slower speed can help reduce warping and curling. Access your printer settings and lower your print speed to 50%. Then, reduce your nozzle temperature by 50% so the adjustments match.
What is a good retraction distance for PETG?
Retraction distance should be set at about 6 or 7 millimeters for Bowden extruders, and 3 or 4 millimeters for direct drive extruders. With PETG, retraction speed is more important than distance. If you still have oozing and stringing, try lowering the retraction speed.
What happens when PETG absorbs moisture?
As the filament absorbs more moisture, all the bubbling, cracking and extruder sounds become more visible. As the absorbed liquid water goes into the hot end, it warms up and becomes steam, causing extruder noises and filament bubbles. As the filaments absorb more water, they make more strings.
Why is my PETG warping?
The problem occurs because the temperature differences between layers of extruded plastic are too big. This, in turn, creates tension within the model, and when it gets to be too much, lower layers start to drag or lift, creating a warp.
When to under extrusion after a layer change?
Right now I think it’s pausing at the layer change, over extruding, then underextruding as it speeds back up. Thinner layers should help (such that the nozzle pressure is lower). Also look at the “spiralize outer contour” feature which doesn’t need to change layers.
What’s the nozzle size for Cura under extrusion?
Had this problem while printing a 3d plane, you need to turn the retract at layer change on then cura will use the extra prime setting at layer change (i have mine at 0.1) What’s your nozzle size? I was going to say try 20mm/sec but you did.
What’s the minimum wall flow for under extrusion?
Enabling Outer Before Inner Walls helped a bit but not completely. Best workaround so far is Retract on Layer Change + Retraction Extra Prime Amount to 1,5 mm3. But I still can’t find the Minimum Wall Flow setting. The only ‘Wall Flow’ I find is ‘Bridge Wall Flow’. Oh, sorry about that.
