I tried a small, simple print using Inova - 1800 today and it looks horrible. I am trying to print the USB support brace that can be found here. https://www.lulzbot.com/learn/forum-pos ... port-brace

However, when I printed it, it looks like this:

I used the profile for Inova - 1800 that is included in CURA 20, standard resolution. I'm guessing that the profile's print temp of 245 is way too high. I will try the settings suggested by CoParaTech

Second attempt w/ new settings

245/70 flow @ 90%

Same result...sloppy

I use 240 for the 1st Layer, and 235 for other layers.

Cooling Fans off on layers 1-3, 30% layer 4, and 50% layer 5 and up.

Simplify 3D, but shouldn't matter.

From the pictures, it almost looks like it's over extruding? Also, what speed are you printing at?

With a TAZ 6 and Simplify3D, my hotend is 250 C and bed is 70 C. My fans kick on to 30% at layer 3 and stay there, but I vary this depending on the size of the part. My spool of blue filament also averages out to about 2.80 mm, so this is the value I use. I have noticed that this filament does fluctuate in diameter a bit.

I'm using CURA 20 and the included profile for Inova 1800 on "standard" resolution.

Print speed: 50 mm/s
Print Temp: 245
Bed Temp: 75

I tried again and reduced the print speed to 40 mm/s with no discernible difference in print quality.

I looked at the S3D Innova-1800 profile I got from the kind C.S.L. person, and I am printing at a 26MM/sec print speed. YMMV! But try printing slower, and I know the amount of the retraction distance affects print quality also(personal experience).
