Try turning the bed heat off and set the extruder temp to 180. Also, make sure the fan is at 100% while printing.

Thanks for the info. I didn’t think it was really bridging but still learning!

I did print 2 at a time but go the same basic result. I have it pretty good for no support (thinking no support was a requirement for test). I have cooling maxed out and print as low as 500mm/min but back up to 1000mm/min seems to get the same result so sped up for time sake!

I’ll give your support suggestions a try to learn and see how it goes.

I think we are gaining on this sucker!

24

I’ll give it a shot. Thanks.

Is there a better/recommended fan set up for the Flashforge Creator Pro 2016? It does have the fan for the left extruder.

26

I have a couple teams now! In different colors. Running two machines on this one!!

Thanks for your suggestion. I tried printing at a much lower speed and that didnt gave any result. First I go calibrate my printer and if that does not work I print 4 of them in 1 go to see what that gives. Let you know when its done.

28

For now I did the following things to make it better:

- Lower the temp 5 degrees (no result)

- Increased the retraction with .5 MM

- Next to my nozzle fan I added a desktop fan to bring more cooling (cleaner model, but still a brow on the left eye)

- Calibrated my layer width (no result)

- Slowed the printer from 3600 to 2800 (no result)

For now I am going to print 4 of them in 1 print and see if that makes it better. Though, I cannot imagine that it should be that you have to print more models to get a clean one… Somewhere, something is going wrong, but I have no clue what… I hope that anyone has some extra tips and tricks.

Did you try turning off the bed heat and setting the extruder heat to 180?

The reason many folks on this board have suggested multiple marvin prints at the same time is that effectively slows down the time between each layer, allowing the previous layer to cool and fully crystalize before the next layer is printed.

This is why I suggested you print it along with another item you are printing, or to print several of them.

It is a tried a true solution that has solved marvin issues in the past, and is a common solution when printing small parts. Inactive cooling.

31

Will try that after my current test is done. Though it is frustrating, I like the getting better prints part of it :slight_smile:

32

With 4 of them there was still a small brow… Next print is 180 with no bed heath.

I have tried 180 but not with the bed off. 180 for the PLA I am using is lower than it likes. The loop at the top will crumble if touched, like it crystalized. It doesn’t react this way when printed at a higher temp.

34

Lower temp and no heatbed indeed ensured is saw no braw above the eye… :slight_smile: Have to keep on testing I guess.

@wirlybird did you already booked some progress?

From what I can tell this issue is caused by the way the nozzle is coming off the print when the slicing is going on. I currently have an army of marvins laughing at me. Every print better than the other but ultimately i think this is an issue resolved in the slicer
