Thanks for the screenshots. In my version of Simplify3D the filament diameter is correct at 2.85mm. However, in your screenshots I see an extrusion multiplier of 2, where I have 1.1 as the default setting. Off course that would be a big difference, but I am a bit cautious to put this value in because it's pretty extreme I think. Are you sure you are actually printing with this multiplier? What are your settings for .06mm layers? I am running S3D 2.2.2 by the way.

Is there a moderator who can move this topic here: http://umforum.ultimaker.com/index.php?/forum/33-other/ I'm pretty sure it's an Simplify3D issue mainly. Thanks

Hoi! Tot mijn verassing trof ik gisteren Cura 15.01 aan bij de downloads. Hierbij zag ik een nieuwe kwaliteit toegevoegd (Ulti, 0.04mm laagdikte). Mijn eerste ervaringen met deze versie van Cura i.c.m. nieuwe UM2 firmware zijn zeer positief: Als je nu van quickprint naar expert switcht vraagt hij of je de quickprint settings wilt overnemen. Ideaal als je wilt tweaken met als uitgangspunt een quickprint setting. Je kunt het materiaal nu wisselen via het menu als je de printer pauzeert. Bij mij leek de eerste laag gelijk beter 'gevuld'. Voorheen had ik dat de lijnen elkaar niet echt lekker raakten. Ook bij 0.01 laagdikte voor de eerste laag gaat het nu goed. Overhangs op 0.06 lukken beter lijkt het (ok, dat kan ook aan andere factoren liggen) Ik heb de 0.04 laagdikte nog niet geprobeerd overigens. Wat zijn jullie ervaringen met deze versie? Groet Björn

From their own FAQ: What Materials work with BuildTak? Works with ABS, PLA, HIPS, PET+, Brick, Wood & Flexible (TPE) filaments; additionally we have had success with getting nylon and t-glase (PETT) to adhere when used with a thin layer of washable glue stick on the BuildTak surface.

I'm curious if it works with Buildtak (http://www.buildtak.com) which I am using.

Makerpoint.nl (own brand): They just answered my question: 260c for the nozzle and 100c for the bed. They expect some adhesion issues on the bed though.

Hi! I bought some Nylon PA12 filament for my UM2. Does anyone know the best temperatures (nozze and bed) to print this? Thanks! Björn

Hi Yellowshark, Thanks for your answer. I think though that what you describe in your first paragraph is about cura? I have Cura at 0.3mm first layer. It's better but still not closed. My examples are about slicing in Simplify3D. In simplify3D you set the 'Primary Layer Thickness' as the overall layer thickness (the layer thickness for the primary extruder, yes it's confusing) and there is a separate box to set thickness and width of the first layer in percentage of the primary layer thickness. In my last example photo above I was printing at 0.1mm, with first layer thickness at 200%, so 0.2mm. In the Simplify3D manual it states that the first layer height doesn't change the amount of material being extruded, so if you print at 0.1 and you set the first layer height 90%, you print 100% of the material on a 0.09 layer, so it should become wider. It also says you can use this to make the first layer thicker as I am trying, but it would still extrude the same amount of material. Changing the first layer width doesn't seem to change that, but it does change the distance between the lines, so if you make the first layer wider it just prints the lines further apart ánd it stops further from the outline (see the most right image on my 3rd photo above). So in conclusion: In Cura I'm getting reasonable results with a .3 layer thickness, although the lines still don't connect entirely. In Simplify3D I am unable to create a .3 first layer with a .1 overal resolution. I must oversee something really basic I think..

Hi all! [uPDATE/ EDIT]: This seems mainly a Simplify3D issue. Edited the below message accordingly. I hope someone can help me out.. I've tried many settings for the first layer in Simplify3D but I get very poor results anyhow. I always have a gap between the lines and if I increase first layer width the gap becomes larger and the infill lines don't touch the outlines anymore. I'm printing PLA, bed is leveled (multiple times) at 1 paper thickness. I'm using buildtak as adhesive layer. Here are some examples I tried with Simplify3D (iphone case @ 50% scale): I really hope someone can tell me what is wrong here and how to fix this.. Thanks Björn
