Colorfabb corkfill help please

[schafe 3]

Hey!!

Here is what I know does not work: Olsson nozzle assy at .4mm, various nozzle temps and a maximum extrusion rate of 60mm/sec for the infill. 5 failures using these settings. The most frustrating one was at hour 18 out of 20. All of the failures were a plugged nozzle.

Before coming to work I put the original Ultimaker nozzle back on. I resliced the print so the speed was not higher than 45mm/sec. I started it again at 210C and 55C with a fast retraction speed. These new settings came from the colorfabb web site. My wife told me it failed. It seems the very first layers did not get built properly and I made spaghetti.

So, has anyone had good results with corkfill and how did you do it?

Thanks

for the fiber filled filaments, go for the 0.6 nozzle with the Olsson block and the settings you already have. Did they mention a flow of 105%?

I printed quite a few times with corkfill, no issues at all but yes .6 nozzle is mandatory (i'll never print wood filled filaments with a .4 nozzle, i still remember that clog i had on the UM2 original nozzle!).

Basic settings for PLA should work, 210 - 215°c, 30mm/s - 50mm/s, as long as you use a bigger nozzle it should work.

Love the chocolate look of corkfill by the way

Thanks for the help. I knew I would get good advice once Europe got out of bed.

I switched to the Olsson block and a .6mm nozzle, resliced and started the print. We will see in a few hours what result I get.

A bigger nozzle makes sense. I was always getting a plugged nozzle.

Oh yes, I checked the colorfabb site and they do not mention anything about nozzle dia. That would have saved me a lot of time and filament.

I have done prints like this with corkfill and a 0.6mm nozzle without any hiccups:

That one took about 57 hours and more than one full spool of CorkFill to complete

Very nice. I consider myself pretty good with the UM2, but I just don't have the nerve to start a several day long print. I would have to divide it into sections.

I have done it quite a few times, my printers are about 25h into printjobs of 43 and 66 hours with XT-CF20 right now :-)

Well Blarp!!

I finally had to switch to a .8mm nozzle. By the time I figured all this out I had used too much of the corkfill. Had to finish the print with bamboofill. Still looks ok, although it was not what I hoped for.
