Why is my post still unpublished?

Check this out. It is a big help.

I find I have to contact support here every time I make a post to get them to actually publish it. It is pretty ridiculous!!

Probably under-extrusion, decrease the filament diameter in simplify3d like 0.3 mm and reprint it.

Hi Robert! Two issues come to my mind. The first is under-extrusion. Set your flow rate to 100% and make sure your filament size is correct. If that does not work set the flow rate to 105% and re-print. If that doesn’t work your nozzle may be clogged. There are multiple ways to try to unclog it. What you want to do is heat it up untill all the filament can drip out. You can use a blow torch to do this if your hot end can’t get hot enough.

Good luck!

I had the same problem managed to narrowed it down the filiment not being pulled into the extruder from the spool properly you can actually hear it sticking I managed fix it by ditching the feed tube and suspending the spool above the printer on a bar held in place with a pair of a frames hope this helps

1. Is this a new printer, or something that started after a long time printing? More information on your current situation would help alot.

If you have been printing a long time - ptfe tube, or need to replace stepper motor wire on the extruder, as it has broken inside and intermittently fails.

If this is a new printer, then software settings.

It could still be software settings. Is it doing it with all files, including files that worked in the past? If so, it is not software.
