Unresolved Print quality issues with E3D v6 and Titan

OK, just installed a Titan extruder with a new E3D v6 and here is my second print. Both prints have great first layers, but all layers afterwards look very, very rough. Does anyone have an idea what might be causing this? I use Simplify 3D and this model was a 0.2 layer height, 35% infill, and five lower layers. PLA at 205 degrees and I'm using an oiler right now to season the nozzle.

 

Did you calibrate your extruder steps? That might help, but there might be something else looking at that print.

 

No, I haven't done that. Is that the process where you measure like 110 or 120mm of filament, print 100mm, the measure the difference? I just printed off an article that explains the process and the steps to adjust accordingly. I haven't done the PID auto-tune either. I haven't tried printing this same model in MatterControl yet, so I think I will do that just to rule out S3D.

 

That is correct. Here's a great video to walk you through it if needed. A PID tune might be good as well with the new hotend. Tom also has a video on that.

 

OK thanks, guys! I will do both ASAP and see if it makes a difference. BTW, I tried the model in MatterControl and got same result. Looks like it only affects non-solid layers, but I may be wrong.

 

Yeah so not a slicer issue. Another thing to make sure is that the hotend is secured with no wobble. I don't know what mount you are using, but that might be a possability.

 

Well, when you guys are right, you are right! Ran PID first just to get that in order and then the extrusion steps. The extrusion amount was supposed to be 100mm, but was 168mm!!! EEPROM setting was 723.98, so I divided 100 by 168, giving me .59523810, which multiplied by 723.98 gave me new steps of 430.94 - almost half. Ran a second test and the intended 100mm extrusion was right at 100mm. Test model in process and so far, looks clean. You guys are the best and thank you!!!

 

That's awesome! I'm glad to here that was the issue. Happy printing buddy. Cheers

 

The test prints were perfect!!!

 

I also recently installed the titan extruder and in the instructions gave a starting estep value of 417 due to the known value of the gears. You should periodically check to make sure the screws secured from titan to motor haven't loosened up. Noticed due to being very warm and light screws need slight re-torquing.

 

Blue lock tite might be the friend you are looking for.

 

I used blue loctite during assembly as well, but found a problem during disassembly where the brass embedded nut in the lower right corner is loose, so the screw just turns aimlessly.

 

Ugh... Yeah I had that issue as well. I put some glue around it and it seemed to help mine.
