Anyone else have trouble with the infill from Cura for ABS?

Anyone else have trouble with the infill from Cura for ABS? My luck for it seems a little unstable. I am using a 0.5mm nozzle. I may want 0.7mm for infill.

I am hoping that if I go to a thicker nozzle, I can not only get the results more stable, but use lower quality filament.

Of course, I would love to hear a solution if someone has one for me. Switching slicers does not count unless it is free, perl free, mono free, and has honeycomb patterns. Slicer is out because it uses perl and mono and is also as slow as hell and it locks up on me.

I imagine an enclosure or waiting till warmer times of the year or using a heat lamp might help if this is actually draft or ABS shrinkage related.

KISSlicer has honeycomb patterns. Perl free. Mono free. Is free. Not Open source though. Paid version allows you to put more than 1 object on the plater, but seriously - it’s worth trying. KISS also has the best support material generation that I’ve seen. It’s completely worth the weird terminology changes you’ll have to get used to.

Also, mind describing in more detail the issues you’re having with Cura infill?

The Cura infill seems to be so thin that the one layer does not stack well on the previous layer. It seems to also occasionally be intentionally drawn in a different x,y position. Sometimes the new layer will not adhere to the previous layer and so that portion of infill will just totally fail.

Is it just the infill that isn’t adhering to the previous layer?

@Christopher_Derewian Right. The infill is doing that. I am also having trouble getting my initial layers to spread on the heated bed, but i believe that is separate issue.

cura-13.11.2-1.fc19.noarch is what I am using right now.

Ok. This is interesting. It seems my extruder was spitting out filament while under temp waiting to heat up. Monoprice black seems to have 2 melting temperatures. You have to remove the nub of filament from the last day’s print session to get things to print ok in the first few layers. That is one mystery solved.

Recalibrated the towers again. Now too high. Set 0.3mm height for the first layer. Using a code to lower the Z by 0.1mm. The result before the 0.1mm lowering had all of the plastic squirting out fine, but with bed adhesion issues and gaps.

I still can’t believe the plastic that melted from the previous day’s prints won’t squirt out in mid are at 240. What the??? What is Monoprice using for a filler?

Oh…and here is a fun one. The heated bed or the delta math is causing the nozzle to be lifted off of the bed in the middle.

I have problems with cura infill being kind of thin and crumbly as well.

I think I still need to retune my calibration some. Oh well. Delta calibration is always a pain for me.

@Hoff_Woohoo What print, filament and Cura version do you have?

Sounds like its not just one issue. After retuning why not try to slowly increase the extruder multiplier. I do apologize for sounding to obvious.

@NathanielStenzel its the latest version of cura. Downloaded it less than a month ago. Rostock 1.75 it did the same with an older version of cura as well.

@Hoff_Woohoo I am confused by what you mean. Got a link for downloading your Acura?

@Christopher_Derewian oh trust me, I have already messed with the extruder multiplier. I might again later but I will tell you I have done that before. Normal areas can end up over extruded while the infill is still weak.

@NathanielStenzel I used one version of cura that I downloaded over a year ago and recently upgraded to the latest version. Both had the thin infill trouble :frowning: I remember googling the issue some time ago and finding that it seemed to be a problem with cura. Infill is great with slic3r. I had better luck changing fill % and it seems better with more solid parts. I love cura other than the infill issue…

@Hoff_Woohoo If only Slicer was written in python instead of Perl (and using Mono), I would be happy with it.

+Nathaniel Stenzel I could love to see it written in Python…
