Wow that is incredibly helpful!
Thank you,
I doesn’t seem to be under-extrusion… check the mesh for errors with some free software. I don’t think is a level issue or a bad screwed z axis, but to be sure check that as well.
hope that helps.
I was kind of thinking that (Based on some reading I have been doing). I did level the bed when I got it, but since I am a newbie I might not have done a great job with it. I haven’t checked the Z axis at all. I will do that right away.
Thanks for your reply!
I opened the file, with cura and repetier host, it looks fine to me. The Gcode generated looks fine. Then I opened it with MODO 102, and it doesn’t have any issues, so the file is OK.
Then I noticed the first layers of your print… and it looks like they printed in thin air. So I guess I should try to print it with some good support first. Maybe try repetier.
Also you may want to try to rotate the print so it prints in the y axis lenght instead of the x axis… and maybe you have better results that way. Also chech that the Z axis couples are secured tight and at the same level.
Or you may want to try printing it flat with supports for the opening in the top ( flat side down, not like it came originally ).
Another thing… just for you to check your printer, you can cut off the object like 1 cm ( advanced settings cura ) and then start a test print so you can see if it continues to do the same thing.
What material is this? Temp is kind of high for PLA and a bit low for ABS.
Hard to say exactly. If your .stl file checks out, then I would look at your settings, layer height, top and bottom layers, wall thickness, infill etc, etc, you are running 30 mms speed, which should give you a good quality print. Look for basic settings that may have been changed by accident. Filament size, nozzle size etc…reposition file in different area of bed and reprint. I assume at that speed, that size file is taking approx. 2.49 hrs. Worth trying a reprint
One more advice
take and increase your layer height to 1.2, increase to top and bottom layers to 1.6, and you wall thickness to 1.2 as well. By increasing those values you are giving more strength to the part. Though I think your intent was more of quality. The problem with such small values is strength and support. The bottom and top layer help hold the infill together and the wall keeps part intact. If you run a low first layer and let’s say you are using glass and hairspray, when you go prying the part out of the bed that first layer may not come out with the piece you are printing. So yeah experiment with those values. And Noob or not everyone has been and worn those boots. Keep on trying
This is also very helpful. I appreciate it!
It is standard PLA. What temperature do you recommend?
I didn’t even know about that setting, thanks!
How much retraction are you using?
Also, what retraction speed are you using?
190-210 depending on the brand but that should be a fairly safe range.
Try rotating or re-orienting the part on the print bed and see if the bad area follows the part or stay in the same location to the machine.
What slicer are you using?
I am using Cura, that is an interesting suggestion. I am going to give it a try!
Last night I checked and my Z-index was way off and my bed was in need of a re-leveling, I haven’t re-printed yet but I feel this will go a long way with the print. Thanks for your help!
yeah. The i3 does not like much more than 1.0 - 1.3mm retraction and 30mm sec speed on retraction… Looks like it is retracting but not returning the filament back to its original position. Possibly slipping during retraction return or retracting too much and getting a little bit stuck or delayed in the cool part of the heat break…
