Re: Gap between infill and perimiter

Does the extruder start where the hole occurs?

If it's at the start it might be the negative extra restart value.

If it's happening at the end of the layer try running with wipe nozzle turned on. Even a low value of 1mm might help close the gap.

Re: Slicer behavior for thin walled sections

Cross sections below the extruder width don't currently print. This shouldn't be a surprise because we want accurate prints. The other slicers that "force" thin walls to print will sacrifice accuracy. Why would we want to print inaccurate parts? It's more accurate to design features to print properl...

Re: Recommend a better printer?

There are so many printers out there at the moment it's hard to nail down an exact model or brand. The most important question to answer before selecting a new printer is "what do I print?". From there narrow down the list based on print size and reviews. Flashforge and Makerbot are two to look at f...

Re: Second extruder pulling up first layer

Once things are leveled properly try printing with the second extruder turned on at a lower temperature. If the first layer is excessively over extruded a properly leveled machine can still drag some. If the second extruder is cold it may hit and knock the print off. If the tip is hot it has a bette...

Re: How to get the smoothest top and bottom layer

One thing that I've noticed with my new resin printer is how well printing parts at angles works. Any time you can print near vertical that side will have a better finish. By printing the part at an angle with supports turned on you can get a uniform look on the part. This may not be the smoothest b...

Re: Trials and tribulations of ABS

I pretty much never use the layer fan for ABS prints. The layer fan almost always pulls the corners up and warps the entire print for me.

Also try different print speeds. Slower first then faster to see how it effects the print.

Re: Adjusting infill density in 3D, not just layer by layer

I would probably try tricking things by cutting the file in two. Create 2 STL's and use processes for each.

Alignment of the parts will be critical.
The parts might not adhere to each other well (probably need to overlap them a little).

Re: More options for stronger infill.

A few more things to try. First, I don't mind the little gaps between the infill directions. If you want the infill to be stronger print several layers in the same direction. Put 2 or 3 lines at 0 degrees in the infill window followed by 2 or 3 lines at 90 degrees. This will add strength without the...

Dual extruder can't specify different filament sizes.

When using a single process it's not possible to set different filament values to each extruder. Filament diameter, print speeds, material costs etc. are often very different between material types. If I could set diameter and speeds for each extruder that would be a good start. Might belong in the ...

Re: different filament color for different extruder in previ

As a work around right now you can apply significantly different speeds for both extruders to check that they are both printing in preview. Just change it once, preview, and change it back. That said, I don't necessarily want to lose the speed based color. A toggle box between speed based colors and...
