Solved Can't complete a print (PLA)

Sorry for the bad camera phone pics.

Couple questions:

#1: I have been printing on a E3d-V6 for a couple weeks now and for the most part its been ok, but as of 3 days ago I am no longer able to complete a print. I was printing a battery dispenser and about 2 hours in, the printer got stuck on a booger, I'm guessing. The print looked great until that point. So I started over and it didn't get stuck, but close to the same point it stopped extruding.

I have since used the canola oil seasoning and switched back to the sample PLA that I seemed to be doing well with before. But as in the attached picture this was the best I could do, some attempts wouldnt even extrude the first layer after the perimeter ring was printed.

I tried ABS but every time i try the abs breaks in the hobbed bolt.

I pulled off the heatsink from the E3d and i see no signs of clogs in the heatsink or the entry of the threaded connector piece to the heat block. (I did the frist time I tried the e3d because i didnt have the heatsink fan on AND i didnt have the PTFE collar and tube.. DOH!) Could this have ruined my e3d? I cleaned it out pretty well and put it back and and got a bunk of pretty good prints. Way more consistent than the stock hot end up until now.

One thing I noticed was even though I ordered .4mm nozzle, visibly the orifice looks smaller than the stock .4mm I assumed it was right and installed it as it doesn't have any markings. I will order more nozzles today to be sure

I wanted to go bowden but cant figure out what else I need to make that happen.

#2: Should I go back to the stock hot end? I only printed about 4 things with it and this is how it looked when I removed it. What would cause the PLA to come out in that area?


OH! one other thing, the magnet came off on the top of the bed. there is a gap between it and the bed. The corners seem to be resting flat on the pads on the bed tray. How can I fix this?

 

Sorry for the delay in update. Fan is working on the hotend heatsink. After I cleaned out the nozzle with a high E guitar string, it seems to be working well with the Robo test PLA. I have also been able to print small parts with MG Chemicals? ABS. Larger prints in ABS warp as I didn't do a slurry.

In short, I think the Black Shaxon PLA and ABS from frys is just JUNK and doesn't work well with my setup. What brand filament should I look for?

Also any recommendation on what to use to reglue the magnet to the bed?

Thanks for you help.

 

"MG Chemicals"? That's a freeze spray and duster brand. What do you mean?

Have you tried Aquanet or equivalent hairspray for ABS? Spray on a cold bed, heat to dry. Print ABS with the bed around 110C.

There are some posts on glueing those magnets back on.

 

I bought a MG Chemicals branded spool of ABS @ 19.99 for .5KG. Using more aquanet seemed to help the first layer curling. Seems to print better than the Shaxon stuff, but I am getting layer separation on larger prints. I need to figure out how to fix that... Of to search.

 

Also I suggest you do a temperature test for each brand and perhaps color. You can edit the gcode to change the temp 5C every 10mm and print a tall block. Then take some pliers to it to see what layers stick together best. Somthing like this http://www.thingiverse.com/thing:217523 . I would start a lower though and not bother with 240C.

 

Sorry I was thinking it was some sort of MG Chemicals adhesive.
