I’m sure some of the 3DP veterans would know what the issue is here… I’m getting some roughness in my prints. This is with ABS. The weird part is, it doesn’t do it on every print and if you notice, some area’s print fine, some not so good…really weird, almost makes me wonder if it’s something to do with the filament… The one that looks slightly nicer was at 230C, bed 99. The really rough one’s were 235, 110C, which is what I normally cook with so not sure what’s going on. Seems like it got worse… These parts were .25 layer height(.35 nozzle), interestingly, I just printed a tiny part with .15 layer height prior and it came out looking great, but I’ve printed at .25 layer height a million times before with great results…I’m wondering if it could be cross contamination with stuff lingering in my nozzle, other filaments etc? all insights are welcomed! Gotta get these prints dialed in, they need to look perfect, they will be going up for sale. another issue is that I’ve started using the LCD lately(SD card). Think I’ll plug in and try to run the same prints on Pronterface to help narrow down the cause. ![20150310_231632.jpg](https://us1.discourse-cdn.com/flex020/uploads/lulzbot/original/2X/3/3ca0874f7f24044ae476073cf7ccae35266287ca.jpeg) ![20150310_231554.jpg](https://us1.discourse-cdn.com/flex020/uploads/lulzbot/original/2X/1/1bd59aeb8721432be8d76e339eb6514257611bbc.jpeg) ![20150310_231545.jpg](https://us1.discourse-cdn.com/flex020/uploads/lulzbot/original/2X/5/581cad7c4112b2c5c973f8d4273c510b2d45d2e6.jpeg) --- _[View the full topic](https://forum.lulzbot.com/t/rough-prints-weird/1434)._
