Topic: p getting fillament out of th extruder

Hello again! I am running out of plastic and want to switch over to my black plastic but I can not get the old white plastic out. How do I do this?

Also I am having top fill issues. What settings do I change to fix the top fill?

Command RH to retract 100mm and the filament should come out the top of the hotend. As for your fill issues I can see several signs of backlash (infill not meeting perimeters and imperfect circles). Follow these instructions to align and set up your drive system properly:

Re: p getting fillament out of th extruder

You look to be under extruding so try increasing your extrusion multiplier.  You are also experiencing some backlash.
As far as switching filament goes, heat up the hot end then release the tension on the tension arm and pull the filament out.  Then stick the new filament in by reversing the process.  Once it is in and you've pushed the new filament out the nozzle you should be set.

BTW  I printed that out but didn't have time to send you a picture.  I'll send it out on Monday and FYI I turned out fine.

Backlash is not backfill, backlash is. Basically play or slop on the mechanical side of things.  Start by tensioning your belts and ensure your extruder head doesn't wobble.

So if you're confident in that (I am not) then decrease the extrusion width for the top layer to something like .36

Friendly FYI Backfill is not a term used in 3dprinting.  I get what your saying though wink
