Im using an Ultimaker 2 Extended, and we have had it about a week or 2 now. Im trying to make a prototype for work and i admit its quite the tricky part but ive been having issues with support in cura, so im now working with simplify3d which i love. Ive been tinkering with settings but stil l have these issues…
What exactly do you need help with? Setting up support with Simplify 3D? Or on Cura?
No I can get the support on simplify, but the issue is in the picture, but after doing some tinkering i tried to add another shell to the surface layer if that would help?
What temp/material are you running?
First try tightening the short belts connecting the x and y motors to the guide rods. That should help a bit.
It also looks like you’re running the plastic slightly too hot, about 5°c less might help, especially with the warping around the bottom support.
Upping the infill overlap or just the flow rate might help as well. If the part is going to be under any load, then the higher flow will help a lot.
Also, try to keep at least 6-8 layers for the top/bottom infill.
If you’re having issues with support, the best bet would be to design your own, that you can remove later. If you have a 0.4 nozzle and layers under 0.15, a simple double wall beneath the rod will be enough and it’s easy to remove afterwards.
Like Munjeni says, try upping the outline overlap percentage: infill > outline overlap (mines on 20%) should get rid of those gaps between infill and shell.
Looks a bit like under extrusion - which can be from too fast, too cold etc. (slow down and heat up :))
In S3D it is worth checking you have your nozzle size at 0.4 and extrusion width 0.4
in Advanced use “gap fill when necessary”
plus I normally use 4-6 layers on the base and 8 on the top when I am slicing 0.15

I suppose that your problem is caused by slack belts. to verify this print a large circle and check if the geometry is correct. If you obtain an ellipse you must tighten the belts, moving the steppers properly.
In your infill properties window change the infill “overfill” (something like that, cant think of them item currently) to 60%. I have not tried it lower than 60% but 60% seems to work. This means that the infill will go over the outer shells by 60% vs the std 20% that it is set too.
Btw I have an Ultimaker 2 Extended I have had for about 3 weeks or so and had to learn this one the hard way with lots of bad prints.I love simplify but takes some times to get the right settings for the printer and what you want to accomplish. I also print at 230C which a bit over the spec of the material.
What temperature are you melting the PLA at?
Im using the same 3d Printer so i will try your settings you mentioned, I’ll repost when i finish my print.
Oh yea i think im running the extruder temp at 205
OKay checked this possiblity but i dont think its the issue, game em all a nice tighten though. The ultimaker robot did fairly well but a little drooping on the bottom below the body
Then you could use this great visual guide
Awesome…great guide thank you!
Alrighty I’ll try to raise the temp but i thought someone stated it was too high in regards to the photo
