Hah, sorry I was messing around with settings a lot and i may have lost the proper file. You are right I set it to exterior only when I generated that gcode. Perhaps if I increase the number of perimeters it won't do that... Upon closer inspection there really doesn't seem to be any overhang that fits your description. I changed the wall thickness to 1.6 mm and reskeined to see if that might solve the issue but it doesn't. Maybe wall thickness is counted differently than extrusion width when calculating whether to fill a layer? But even then, some layers are partially sparse-filled which skeinforge does not normally do, right? I doubt this; the same thing happened on another, quite low poly model too. One similarity between that model and the lion is they are both organic-shaped (rounded over). I might try it out. I was hoping to print another model that has this same problem; that one definitely needs support.

Thanks for all the responses by the way. This helped a lot. I just changed the option to have fan always on to false in that settings.py file. I'm printing with PLA. IT is possible that I have my extrusion temp too low, but I am trying to make it as low as possible so as to minimize leakage and stringing. And if I need to increase the temperature just to get over having a fan on for the first layer that seems like a waste of energy. I'll let you know when I get my HBP working and start (ulti)makin' stuff out of ABS. What I want is to be able to configure the slicer to my machine, while still retaining the ease of use afforded by your simple calibration. With the wide variety in fan systems, some people would want their fan on at the beginning and others wouldn't. Some people want the fan PWM set higher or lower because their fans are more/less powerful. Besides, you don't know the best settings for _every_ machine; providing suggested settings but allowing tweaking of everything by those who have strange setups/ more knowhow makes your software more usable by more people. Unless you only ever want ultimaker-users to use Cura. Then forget everything I said.

I am trying to make this object http://www.thingiverse.com/thing:7930 And what I get is 100% fill on every layer, some layers look like they have a bit of sparse infill but the layer directly above is 100% infill again. Seems like SkeinPyPy is messing up? This slices fine with slic3r. Here is an example of what I'm talking about, from printrun's visualization. I've tried changing the settings like fill density, etc. No difference. Other objects that are more square slice fine. For example this http://www.thingiverse.com/thing:17768 slices and prints just fine, with sparse infill and everything. Here are my settings: [profile]filament_diameter = 2.889nozzle_size = 0.4machine_center_x = 100machine_center_y = 100layer_height = 0.2wall_thickness = 0.8solid_layer_thickness = 0.6fill_density = 20skirt_line_count = 1skirt_gap = 6.0print_speed = 50print_temperature = 0support = Empty Layers Onlyfilament_density = 1.00retraction_min_travel = 5.0retraction_speed = 13.5retraction_amount = 0.0retraction_extra = 0.0travel_speed = 150max_z_speed = 1.0bottom_layer_speed = 10cool_min_layer_time = 10model_scale = 1.0flip_x = Falseflip_y = Falseflip_z = Falsemodel_rotate_base = 0model_multiply_x = 1model_multiply_y = 1extra_base_wall_thickness = 0.0sequence = Loops > Perimeter > Infillforce_first_layer_sequence = Trueinfill_type = Linesolid_top = Truefill_overlap = 15support_rate = 100support_distance = 0.5joris = False

I disagree. Here is a screenshot On the right is a view from skeinpypy, on the left is the gcode generated. You know it actually seems like it is using the wrong start.gcode entirely... but my Z0.35 is set properly... This is makes little sense.. EDIT: Oh and as for the purpose.. I cannot get my first layer to stick if i have the fan on. Now what I do is turn the fan on manually after the first layer, but it would be nice for skeinpypy to do it automatically. Also, I know that Cura is supposed to make the settings easy, but why not allow someone to change ALL the complex settings in the "expert" tab? I can think of no reason not to do that, and it would be more convenient. This would allow people to access the raft settings, first layer temperature, etc.

I think the problem is in the one layer of plywood between the arms, because that's what the stage is attached to. I'm not near my UM at the moment but its good to hear that you got everything tight. It means my issue is probably an assembly issue and thus fixable. I'll report back once I get home and scrutinize it more closely.

The flex is coming from the entire wooden stage assembly. That part moves by ~3 mm at the forward edge when i touch it with mild force. The mild force occurs when i try to adjust the bed leveling screws, which is making it really hard to put the bed exactly at nozzle height, not to mention probably causing some of my bulging layer issues during printing. So yes, I am aware of the springs and this is something different. I can tighten the springs all the way down and that flex will still be there.

Using Skeinpypy beta 4 Maybe I'm just thick but i can't find the setting for turning off the fan on the first layer/ turning its speed down for the rest of the build. I've had to go in by hand and do it but that's supremely annoying. Alternatively, is it possible to automatically post-process the gcode with another script like you can with slic3r? Where does the spreadsheet of skeinforge options get hidden? Couldn't find that either.

So I have been able to print a couple of things on my new UM, but the one thing that's bothering me is the need to level my stage every time. When doing this i noticed that the far edge screws (towards the front of the machine; away from the rods & leadscrew) are actually kinda useless because the entire platform flexes ~2 mm when I apply any tiny amount of pressure on the screws in the process of leveling the stage. This makes it difficult to level the stage because i have to move the print head over there and very CAREFULLY turn the (difficult to turn) screws without putting any downwards pressure on the platform. This can't be right. Is it normal to have that much flex? Did I miss something during assembly? Is there any object I can print out to make alleviate this problem?

Yes I had one of those. I think every single acrylic trapped nut part broke off. And I fried my motor controller trying to push abs through it. Then the bearing holders broke. Acrylic is not a good material for extruders!

AND very thermally insulating. There's a reason why they use ceramic tape to insulate reprap hot ends... space shuttle tiles, etc. (not that your bathroom is made of the same stuff that the space shuttle is, but they are both ceramic materials). I imagine it would take a lot longer to heat up plus might have uneven heating... What is wrong with aluminum?

I would put the aluminum plate bed up on risers from the stock plate. Sure you lose some z travel but the heat barrier would be worth it.

Has anyone tried replacing the stock ultimaker knurled bolt with one made using a tap? It seems to me like the tapped bolts grip the filament better, with no cleaning required. I'm going to try it on mine as soon as I get everything put together. Any reason why that won't work?

Mine shipped too! That was awesome ultimaking, three week turnaround for the WIN. Anxiously awaiting... Probably about a week shipment to the US from Netherlands huh...
