Topic: Is this normal? Or... How do I fix this?

I've been playing with a solidoodle 2 for a few days. It was frustrating at first but after discovering the hairspray trick things are looking up! On Friday I printed a few bunnies and the kids in school loved watching them be printed. They came out great!

Today I printed an iPhone case and now I have some questions. Should the results of a print look like this? I also noticed that the extruded was leaking when moving to a different area leaving a mess at the start of the new bead. Is there a setting I need to adjust to keep this from happening?

No they should not look like that. Are you using skeinforge or slic3r?

Have you done all the calibrations and measured your filament in several places and averaged the width in your slicing app? What temps are you using?

Re: Is this normal? Or... How do I fix this?

I did measure my filament and it was between 1.5 and 1.67 mm. My bed is at 100 and extruder at 195. I checked the table clearance at 0 with a piece of paper. Should I slow the flow down a bit? And what would a good number be? Another adjustment would be retracting the material from the extruder?

I'm not sure if any of this would work and I'm looking for some expertise from you all.


Thanks for the replies so far.

I think what your looking for falls into retraction settings, basically you need to tell the printer to pull back more filament while its jogging to its next start point,  to prevent the dripping and other nuisances your getting 

All in all a good thorough calibration wont hurt.

Your flow rate is too high for your filament, too much material being pushed out.  Print out a single wall box and measure the thickness.

Re: Is this normal? Or... How do I fix this?

I think I fixed most of the problems. First I had to drop the screw for the table limit switch? That gave me a nice bead on the table. Second I adjusted the retraction  setting to 2.1mm, that kept the material inside the extruder.

Now I have some wobble between layers that I have to sort out. I'm thinking of a third leg for the table, so it wouldn't move from side to side or front and back. Has anybody else done this mod?

The forum won't let me load Picts from my gen 1 iPad so I'll upload Picts of my progress later.

Yep, looks like you got your printer dialed in better. That case print looks great.
