Solidoodle 2 putting holes in prints, infill is broken. Sigh.

Looks like your settings are a bit messed up... hard to tell from the pic as my monitor is just about on it's last leg... but it could be you have a partial clog.

what version of software are you using? slicer didn't like anything but rectilinear in the infill settings for a while I see you have line set for normal fill pattern... that could be messing with you

after 5 posts you should be able to post links

The guitar string technique will work... but sometimes it will not completely eliminate a clog only move it around inside the nozzle... does the extruder extrude straight down when extruding into thin air or does it show any signs of curling while coming out of the nozzle?

It does curl a bit when it comes out, but it's done that since the first day I got it. I didn't think that was abnormal at all.

I think you're not putting out enough filament then.  Have you calibrated your extruder?  And also, a problem I had in the past, is it accidentally set to 3mm filament instead of 1.75?  Finally, what is your extrusion multiplier set to?

There poeple on here that would know more than me, but those settings look way off.  Your minimum parameters is set to 75?  There are also settings that if not set correctly will cause slicer to fail to slice. Usually during the infill calculations. It took me a awhile to figure out some of the basics and there are some things I still don't understand. But again, those settings look way off.

well I guess other things are off, because right there changing that setting will make you extrude more then twice as much filament. (I think)

When you changed it, did you select the new filament settings before you sliced? I've confused myself many times when I change a setting, slice, and realize that repetier was still on an old profile.

If you want some settings that work, try these:  (keep in mind I'm only listing what values to change, everything I dont mention just leave as you have it the same as me)

on the printer settings / Extruder 1:

Nozzle diameter:  .4

Length:  2.5mm
Speed: 150

on print settings / advanced  (this is what I suspect is wrong)

change ALL of them to .42 except Support, which I have at .31     so the first six make .42 and the last one .31.

on infill: 

fill density:  0.3
fill pattern: honeycomb

solid infill every 0 layers

uncheck retract when crossing perimeters.

on layers and perimeters:

layer height (Whatever you want, though for most parts I use 0.3 unless I'm going for looks)

first later also 0.3000

perimeters 3.  (not 75 that's really really wrong!!)

I randomize starting points.

I usually only have 4 solid layers on the top and 3 on the bottom. Its enough and saves some time/material.

Anyway, with all of that you should see a massive improvement because yeah, your settings are /way/ off.  And be sure to check the filament settings and make sure they are right.  Also, if I remember, the trend for solidoodles is an overcalibrated extruder. (IE it seems to extrude too much, as in 130mm when it should be 100.  At least thats what mine and a few I've seen did.  Look up how to calibrate it, it helps.)

Let us know how these fixes help!  Also please post a screenshot of your filament settings.

Finally one last note.  Whenever I change certain things to Zero in slic3r it seems to snap back.  So read your settings after you save and make sure they held. If they do not hold, change it to 1 before changing to zero and vice versa, seems to fix for me, once again, has confused me many many times.

Good luck!

That's a huge amount of overextrusion, I think your best bet is to get back to factory settings and work from there... the factory settings are actually not as bad as most people would have you believe... well except for the 30 percent over-extrusion amount anyway... but that is easily corrected as shown in the video link by Ian in my earlier post. The way you have the settings now makes slic3r not do what it is supposed to do, I'm kinda surprised it printed as good as it did in your first pic.

He made that vid a while back but everything pretty much still applies to current SD's, he was using pronterface but all the gcode and repetier stuff is basically the same.
once you figure out how much the extruder stepper is off use this next link to correct it.

Well, I think i found the problem!

I ran the test on the extrusion calibration like ian johnson did in his video with the sharpie, and get this-

When i extruded 100mm in repetier, it extruded not 150, not 175, not 200, but 257mm, a whole 157mm over the amount instead!!

I am really shocked my extruder is that screwed up on the calibration. So now that I figured that out, where do I go in slic3r to change the setting and set it back? How do I determine what number to put as well since its extruding way over 100% more?

When I bring up the EEPROM settings window, this is all that comes up.
