I sometimes get the ghosting, but it usually goes away after a few layers. 
Have you measured the filament diameter along several points with good calipers and entered that in to slicer?  You might me putting out too much material. 
Try dropping your bed just a bit to give the first layer more room.

Hope this helps,
Michael

Probably too late for you, but try a hobby shop that has remote control cars/trucks.  They will usually have an assortment of metric stuff.

We have been having similiar problems with some PLA's.  Take a look here http://forum.bukobot.com/index.php?topic=3067.msg4802#msg4802

I ordered my garolite.  What have you guys tried for drying nylon?

Thanks!

Thanks Milo!
I tried this with 3 in 1 oil and it worked pretty well.  I might try a thinner oil next...  maybe gun oil?

I bought that PLA based off the strong recommendation on this page.  http://bukobot.com/3d-printing-bukobot-faq
Maybe that info should be removed so nobody else does the same.

General 3D Printing Talk / PrintBL Sapphire PLA... no worky... suggestions?
« on: February 08, 2014, 08:36:48 PM »
Hi guys,
I've had my duo for a few months.  I've been running ultimachine black ABS, natural HIPS,  and a gray PLA sample they sent me without issue.  I've also been using the yellow and red/orange samples that came with the bukobot.  Are they diamond age from printbl? 

Last week I received a 1kg roll of sapphire PLA from PrintBL.  I've made around 20 attempted prints.  Only one has completed correctly (an iphone case).
I'm getting excessive extruder clicking/skipping to the point that it isn't putting out much at all, but it only happens on thinner walls. 
I've tried temps from 170 to 210.  I've also tried slowing down the print speed.
I've switched to the second extruder hoping that would help.
I've disassembled the extruder and tried to free it up a little (assuming too much drag).
I've increased the voltage to 13.8 with the trim pot on the power supply.  I have not tried reducing it below 12.
I've removed material from the plastic piece the locking lever rests against to reduce the pinching force on the filament.

My other 3 pla filaments work fine.  Any suggestions would be greatly appreciated.

Thanks,
Michael

update...  It didn't fix it, but it helped.

Spoke too soon.  It helped, but didn't cure the problem.  My ultimachine ABS and PLA print great as do the samples sent with the printer, but this printbl stuff is just too hard I guess.

I had the same problem with mine.  I fixed it by simply loosening the black screw that holds the extruder assemble down and sliding some paper shims underneath the low one.  This assumes you already have your bed setup.

I've had stalling problems on my Duo since I built it a little over a month ago.  I slightly loosened the screws on the front of the extruder.  It helped and I was able to print with my ABS and included PLA samples.   

I few days ago I received my sapphire PLA from printBL.  I started constantly getting stalling problems with the new filament (it feels harder than the other filaments I've printed with).  I wasn't able to get a complete print, but my ABS and HIPS printed fine.   I disassembled and reassembled the primary extruder to check for binding, but it didn't help.

Yesterday I decided that tensioner lever was putting too much pressure on the filament and creating extra drag.  I took a dremel to the tube that the lever locks against and made a flat spot.  This way if it didn't work I could always rotate the tube to a non-flat spot and it will be like it was before.  It worked wonderfully with my new sapphire printbl PLA that I was previously unable to complete a print with.  I have attached a picture.  I need to do more testing, but I think I might have it fixed.
