IMO the maybe top layer is not thick enough, and it could be some under extrusion in the body of the print, hard to see from the photo. you should post all of your settings to help with diagnosis, also what extruder feeder are you using - the standard one ?

I thought you were one of the good guy - now I am not so sure - cruel idea

I was also struggling to think what I had done wrong to be disconnected from my life line

Q1 it probably is worth looking at it to check for wear and deformation, my last one lasted about 600 hours, but it depends on what print material you have been using. Higher temp material seems to cause more wear Q2 new teflon coupler was introduced last spring (April/May) last year I would also recommend its time for lubrication of all the rods too, I use thin oil on a cloth for the rods and grease for the Z axis

That's really impressive and ambitious, I turned a job down because it would have run for 50 hours, need to reflect on that perhaps next time

suggest you try a bit slower say 50mm/s or less, also that looks like a very very big brim, but maybe its part of the print ?

I agree, and am sorry to say the only reason I would buy filament from Ultimaker is if I needed some other printer parts (to share out the postage costs) like a Teflon coupler or new print head Otherwise its Colorfabb all the way for me

welcome to the forum I would suggest you check the connectors to the fans by moving the black braided cable above the print head when they have slowed. If the come back to life you have a problem with these wires. On my printer the wires eventually pulled out of the connector blocks (I think they are only crimped in), I had to resurrect my soldering skills, if this is the problem you will need to disassemble the print head to check the connectors This may seem daunting the first time but its not that difficult really

Hi Lance, saw your post last evening, liked the bracelet design so much I had a go at printing it, first try one piece did not adhere properly to the bed on the first layer so I aborted. Second attempt perfect with a little fresh pva stick glue on the bed at temp 60, first layer print head at 218 then down to 210 fans not more than 70%, speed about 40 for first layer then 50 for the rest. I checked progress at the and and slowed things down for the catch to about 30 and fans full on. its impressed my wife with her morning cup of tea, hope this info helps you

no it will not work, I bought some (from China) and it pulls out of the coupler while printing, its best to source 1/4 by 1/8 inch

Anders I am late to this thread, but if possible I would love to get two to experiment with, can't find any mention of the cost I am happy to pay you of course Stu

plus 1 for the low friction spooler it helps a lot

plus 1 to Didier's last comment, My print quality improved with changes to the filament feeder, I can understand your reluctance to modifying the printer, but I think if it as like buying a sports car and tuning it up to get better performance The feeder I am using currently is http://www.youmagine.com/designs/2904 I find its good for all types of filament, its a design that I think would be well suited to flexible filament too

I had lots of problems initially with woodfll from Colorfab, which I assume is similar to laywood my problems were greatly improved by increasing the layer height. From memory it was more than 0.2 or maybe even 0.25 after this it printed very well, the finish is on the rough side anyway with woodfil - I guess its all about keeping the filament flowing at a good speed. hope this helps

first thoughts , print speed is too fast for the temperature, I almost always print at 50, with a temp of about 218-220, also your resolution is high, I get very excellent results at layer thickness of 0.10 strongly suggest you follow the links at the bottom of IRobertI's post they are really informative bon chance

need some basic information in order to help you, what printer do you have I assume an Ultimaker 2, materiel is PLA ?, temperature, speed, infill %, are you using simple settings or advanced first thought is that the infill looks a bit sparse, so maybe try a higher value

Well I have to admit that on reading the title of this post to being a bit sceptical, but the article is of serious scientific merit. I need to reflect on better air circulation at least - thanks for the heads-up Printerfan

really impressive idea, can't wait to try it

As Kolia sugested just search for Ultimaker and you will be suprised ! for just the isolator http://www.aliexpress.com/item/-/1959140480.html that's €13.06 for two and free delivery. But be aware that its the 'old' material just Teflon but at that price !

I am the guy who was always against Faberdashery but this may be a game changer !!

I have today made a big step forward with a problem roll of clear PLA, it was down to the last 10meters on the roll and whatever I tried to print there was always random under extrusion, I tried changes to speed temp flow rate etc nothing worked The solution was the filament was very tightly wound on to its roll and as it unrolled it seemed to remember the tight coil. UM clear PLA is a little stick and even with the reel on the floor (with a modified iRobert spool centre) it would come off in loops, this seemed to create some resistance to the extruder feeder. My solution was to warm the filament with boiling water and then straighten it before re-coiling onto a bigger diameter it is now printing with no problem at all The feeder is not clicking at all, I always understood that this clicking was too much resistance at the print head, but it would seem that it can also be caused by some resistance at the input end of the feeder :cool:

bonjour izo2 are you using rafting ? its the only way to go with ABS, also do you have the latest firmware installed that's 14.09

really great piece of work just a thought - that would look wonderful in bronzefill !

you don't know just how lucky you are !!! It too me several months before I could join the 10mm high club - but once there you have only to print all the time congratulations - good luck !!

It has a metalic sound when knocked against a desk for instance, its a lot heavier than plastic,but it is more brittle just had a piece break in half never happened with the same item in regular PLA still it looks great when polished up
