Unresolved First layer Wavy

Thanks Geof. Definitely think it was an extruder problem. Tightened the screws and also cleaned the nozzle with cleaning filament.

So I printed a test calibration print. I purposely printed it a little larger. Iknow that's kind of cheating but I wanted to see how the printer would do. Especially since this was the first thing I have printed using S3D. I would like you guys' opinion on tweaks. A couple of thoughts I have on it.
1 - First layer is definitely not squished down enough. This was with Z offset at 0. What range should I put the z offset at? What do you guys run at? I know each printer is different, but it should give me a general idea.
2 - It doesn't look like the filament is touching the outline in some places. In MC that was fixed by the overlap setting. I will try the z offset first because it might fix this as well, but if not, where is the overlap setting in S3D?
3 - Bridging came out very well - as in it was complete - but there are some strings where it looked like it didn't quite make it. Those were very easy to remove and the bridge looks good. Are those strings avoidable, or should i even worry about them? Is there a setting to fix that on bridging?

Thanks again for all of the help!

 

Thanks Geof! For the fff files, should i have multiple ones for each material - similar to MC?

 

Thanks Geof. That's exactly what I was thinking - since each filament can require vastly different temps, settings, etc. Is there a good S3D for dummies to help me with all of these settings?

 

Also - where does the m565 command go and couldn't I just put that in the offset tab of the fff under gcode? It shows x, y, and z ith options to change each one.

 

For bridging, when I added my dual fans that made a drastic difference. Also under temperature tab, I decrease the extruder temp just before the bridging layer starts by at least 5 degrees. There are also setting in the Other tab for bridging. If you plan to get it dialed in, I used this thing: http://www.thingiverse.com/thing:12925. I also created a separate profile for bridging, mostly for reference, since only a few settings get modified.

This guy has some pretty old but good videos on S3D:

 

Thanks Ryan!

One more question - should I not have more than one process (FFF) under the processes block? Do I need to remove one? I have two in there now - my modified one and the one Geof sent me. Which will it default to or will it confuse it having two there?

 

Multiple processes can be used if printing multiple parts and want different settings for each part. It can also be used to change settings mid-print by Starting and Stopping printing at a certain height (Advanced Tab). One of the videos by The Hot End explains this pretty well, showing different infill and layer height for different parts.

 

You can select a particular model by double-clicking the process and select the Select Models button in lower left corner. I believe it asks you which process you want to use when you Prepare to Print.

 

Thanks Ryan. Got it. Another question regarding z offset, whose concept seems to be kicking my butt, I have the z-offset (M565) command that was in the process file I got from Geof and it is -.74. I think it might need to go a little closer to the bed. Does that mean I need to make it .8 or .7 to get it closer to the bed?

 

Thanks Geof. It kills me. I have three degrees including two graduate degrees and that offset kicks my butt. I think it's all of the instructions - to include GCode WIki and S3D that say that a negative number will move the nozzle closer to the bed. I wish there was a graphic - like a set of axis with values that showed that graphically..

 

I will say - there is absolutely no question about it in my opinion - S3D slices MUCH MUCH CLEANER than MC. The difference is night and day on print quality, etc on the same print using S3D. Even if I had no desire to modify all of the settings it has, it is simply better at what it does. Then again...it should be for $150!
