I’ve been having problems with my current print. I am using ABS on a TAZ 5. Filament Temp is 235 and bed temp is 100. After about 7 perfect layers the next layer will not adhere. As you can see from the picture it starts looking like a cheese grader. No fan running. I have never seen this before. ![]() I have rotated the print 90 deg. and no change. Any help would be MUCH appreciated. Brett ![ABS printing error.jpg](https://us1.discourse-cdn.com/flex020/uploads/lulzbot/original/2X/9/92b9460f079f2f43a200543d59c1aa26976bd969.jpeg) ---

Bad filament, wrong bed temperature, wrong fan cooling settings are three possibilities I can think of. What brand is the filament, how long has it been stored? Also, try changing bed temperature, printing with fan off, and printing with fan full on. ---

Good advice above, I print ABS at 245- 250, bed at 110 and no fan ever. IF the plastic has not been stored correctly, and has moisture might be a problem I always double bag mine and use desiccant. ---

I’d check for oils on the bed from a hand. Try cleaning it with Isopropyl Alchohol (make sure the bed is cold) and see if that improves things. Other things that can cause that are a corner off on leveling, or goo on the bearings causing skipping. ---

Do you have problems with other prints? To me it looks like the junk layer is being printed way too high. Did you try and re-slice the model? It looks to me like it went up in Z more than it should have. ---

Since its not the layer that sets directly on the bed I doubt if oil or contamination on the bed would be an issue. I would believe bad ABS or material that had been exposed to moisture. Do you have another roll to try… with the same settings. ---

Update, Thanks for all the input. Since it always happened on the same layer I had to assume it was the Slice. I re-exported the STL and Slic3ed again. I also lowered the layer height to .2 and upped the Temp to 245 deg. It printed perfectly.
