Strange retraction/underextruding behavior.

[Kyletr76 0]

For some strange reason, I'm getting some odd retraction behavior in my 3D prints. It constantly retracts when it should be printing solid, leaving a honeycomb pattern behind. I'm running Cura 4.6.1, I'll attach the G-code and a photo of the result, I'm not technical enough to interpret the G-code myself. I have a ANET E12 if that helps anything. appreciate the responses and help, let me know if you need anymore info.

Wow, what speeds did you set when you sliced it, from the simulation it looks far too fast.

You're using a lot of retraction (7.5mm), perhaps that's too much and the extruder is sucking in a lot of air?

I do appreciate the assistance and tried both things listed above. One of them worked and I'm no longer having the issue. I thank you both for your help!

Go on, tell us, was it too fast or too much retraction causing the issue?

I may have spoke too soon, it didn't work. Just tried printing another part and same problem, the exturder gear is clicking back while its printing. I put some tape on the end of my extruder gear and took a video to better show the issue. Starting to think it may be a mechanical issue with the printer.

Hi Kyletr76,

I guess tha Anet is a direct drive printer, right or am I wrong? If yes your retraction distance should be around 2,0mm. If your frame is not enough rigid (did you upgrade it?) your speed should go down a bit. Best pratice is make a retraction test to calibrate your values, it's easy to find it in Thinginverse. I Hope it helps

 

P.S. here is a retraction test (for bowden style printers) changing values doing multiple process in Simplify3D
