February Puzzler
This month's puzzler comes from Matthew. Reply in the comments with your answers. The first to answer correctly will win a 5lb spool of PLA!
"The other day I was preparing a print that required dense infill on the bottom of the part and then sparse infill for the rest of the build. I thought I was being pretty smart and using the advanced options in Simplify3D to create two processes. When I prepared the toolpath it revealed a strange layer as seen in the photo above. This was more than an abnormality on my computer screen, it actually left a visible mark on the print. Name the two settings in Simplify3D that can cause this abnormal layer."
Good luck everyone!

Forgot to add that we're letting it go until March 15th. We will then look through the comments and see who was the first to answer correctly

Mike - Are we suppose to answer here in the comments or send our answer to you directly?

Hey Patrick, your answer should be commented here and will be public. There is a timestamp so we know who commented first.

We had that problem when we first started with multi-process prints last summer at the Clear Lake City-County Freeman Branch Library. It was quite noticeable on this Freddy Fazbear print:

I do remember the settings we changed to prevent this artifact, but since we won a prize during the last open house, I'll hold off on my answer and help spread the free-filament cheer.

I can't tell from the picture if the hiccup was at the interface between the two processes. If it is, my guess is that you failed to properly match the first layer height and width in the second process with the ending layer height and width of the first process.

Darrel - I don't know if that's the answer re:3D is looking for, but those are the two parameters we needed to change to get a more smooth transition.

Here are the two reasons you will see a visible mark between processes.
Answer #1. If the SECOND process settings (upper part of the print) has "First layer height" that does not match the layer height for the FIRST process there will be an odd layer thickness visible on your print. Make sure the first layer height and first layer speed for the SECOND process are set to 100%
Answer #2. When setting the "Stop Printing at Height" make sure the dimension is an even multiple of your layer height. Don't forget to account for any changes in layer height if you enter a value other than 100% for the FIRST process "First Layer Height"!
Since Darrel had one of the two correct answers we will be sending you half a spool of filament :) Just kidding Darrel! Thanks for playing and keep an eye out for next month's puzzler.
