I did sent you a project file with 9 items in it, can you open this? I also asked what kind of printer do you have? And warned you about the possibility that a brim is active by default that is 20 lines/7 mm wide, that takes up a lot of room around your model. Did you try to change this?

I used Cura 2.5 Beta with 8 components and it worked as expected...

bummer, I thought so..... I'm stuck at OpenGL 3.3...

@ultiarjan how did you get this layer view? Is it the difference Mac-Windows? (I want this too...) https://twitter.com/UltiArjan takes up a lot of space....

spiralize only works if it makes a continues path around the object, otherwise the spiral will be broken... so, no jumps to another area... It can only make one extruded line around the object, which you can set to a thicker line width within margins, like a 0.4 nozzle making a 0.5 line width. Keep in mind: a normal layer will print its information and after that the build plate lowers a bit to start the next layer. With spiralize the build plate gradually lowers during the printed layers (feel at the z-leadscrew in the back of the printer, or listen).

I had an older version installed, the most recent one fixed the problem... works great!

I asked, because with a lot of organic models I printed lately it doesn't do anything. If I load a cube and rotate it on its point, it reacts as expected, but if I have an organic model and rotate it in a position where a lot of red shows it does nothing...

I think that doesn't work because Cura drops the model in the centre of the build plate. To bypass this you could draw a plane together with your model, and place the models on that plane on the desired position. Make that plane a solid and less than the first layers so it doesn't print. BUT, because of the multiple grey areas on the build plate the size of the biggest rectangle that just drops in the centre without greying out is 179 by 183 mm. If this is within your region, just print the object and make sure (in the layer view) that the plane is not printed. If your model needs to be printed outside this size of the plane you can manually move the object outside the plane, accurately done with the coordinates in the move menu. So the steps would be: 1. draw a plane/box of 179 (x) - 183 (y) - 0.02 (z) mm. 2. place you objects on the plane, align the bottoms (z). 3. export all models as separate stl's 4. load stl's in Cura, select both and right click - merge. They will move away and grey out probably. 5. in the move setting, set the x and y back to zero, everything should be yellow now. This is your guaranteed position related to 'centre on platform'. If your model needs to be printed outside the plane, ungroup and move with coordinates in the move settings. If you need a skirt or brim you can delete the plane and load it back in if you need another print in place.. Hope this helps your needs...

does this still work with 2.4 and 2.5 Beta?

on all the walls/sides, not the horizontal top/bottom layers.

Maybe it is better if you chance only the first layer thickness to 0.15, then you can keep the rest at 0.1, as you planned. Looks like there is just a little bit of space underneath the flat surface.

this does work in Cura as well, just save a cilinder shape and import it in Cura together with your object, scale its size, set the height as the first layer, multiply when needed and move them close to the corners of your object. You can print the cilinder, but you can also use the 'per model settings' and set the walls, top, bottom, infill to zero and only the extended brim gets printed. Great idea @neotko!

no, this is because of the infill. Tick the box 'outer wall before infill'.

can you check under: preferences - general - if this box is ticked: automatically drop models to the build plate.

what does this mean for others who need the update? Is this an occasional thing?

I found this video interesting and think you will like it too...

no, that is too long

another way to do this is to print a thin disc, a little wider then your overhang, subtract it from your model and put it in when it reaches the top rim. The disc will be incorporated when the print continues.

put blue tape on top of your printed support, make a pause on the last open layer and put you support piece in and resume. Best is to have your speed dialed down at this point to have a good adhesion to the tape. I did use this method to connect earlier printed links tomake a chain

did you wait long enough? The start up is 'long', wait for it before doing anything else..

@ahoeben you're reply was faster then my reply... the default start code has a fixed F6000 (too fast for this printer) so changing the "{travel_speed} should be {speed_travel}" would be enough?

the default Delta start code is: G28 ;Home G1 Z15.0 F6000 ;Move the platform down 15mm ;Prime the extruder G92 E0 G1 F200 E3 G92 E0 should I use this one? it does say the same in values... although the description should not say: move the platform down... because it can't..

Thanks for answering.. I copied the sart and end code from 15.04, does it look OK? (no idea what you mean with {replacement_patterns}...) start; ;Basic settings: Layer height: {layer_height} Walls: {wall_thickness} Fill: {fill_density} ;Print time: {print_time} ;Filament used: {filament_amount}m {filament_weight}g ;Filament cost: {filament_cost} ;M190 S{print_bed_temperature} ;Uncomment to add your own bed temperature line ;M109 S{print_temperature} ;Uncomment to add your own temperature line G21 ;metric values G90 ;absolute positioning M82 ;set extruder to absolute mode M107 ;start with the fan off G28 X0 Y0 ;move X/Y to min endstops G28 Z0 ;move Z to min endstops G1 Z15.0 F{travel_speed} ;move the platform down 15mm G92 E0 ;zero the extruded length G1 F200 E3 ;extrude 3mm of feed stock G92 E0 ;zero the extruded length again G1 F{travel_speed} ;Put printing message on LCD screen M117 Printing... end: M104 S0 ;extruder heater off M140 S0 ;heated bed heater off (if you have it) G91 ;relative positioning G1 E-1 F300 ;retract the filament a bit before lifting the nozzle, to release some of the pressure G1 Z+0.5 E-5 X-20 Y-20 F{travel_speed} ;move Z up a bit and retract filament even more G28 X0 Y0 ;move X/Y to min endstops, so the head is out of the way ;M84 ;steppers off G90 ;absolute positioning ;{profile_string}

Can somebody help me before doing something stupid? I did some little tests with wire printing (experimental tab) on the UM2+, this looks good and with some tweaking it is possible to achieve something acceptable. This is a 6 cm small torso, but I a have a big Delta printer available and want to try this at 50 cm (life size). Now I noticed with the UM2+ that the buil plate/z axes takes care of the 'wire' movements. With a Delta the bed is fixed and the arms move; does wire printing the same on a UM as on a Delta? part of the gcode (think it looks good, doing z movements from Z1 to Z21 and back): ;LAYER:1 M106 S255 ;TYPE:SUPPORT G1 F1200 E6976.01195 G0 F2400 X1.346 Y97.167 Z20.1 G0 X1.346 Y97.167 Z1 G1 F1200 E6996.01195 G92 E0 G1 F326.1 X2.565 Y90.78 Z21.948 E20.18124 G1 F300 X-1.605 Y92.708 E24.77538 G1 X-18.285 Y100.424 Z1 E52.64252 G4 P500 G1 F150 X-18.285 Y100.424 Z2 E54.64252 G1 F324.3 X-19.46 Y92.783 Z21.95 E74.43592 G1 F300 X-23.827 Y95.183 E79.41896 G1 X-41.299 Y104.786 Z1 E108.33938 G4 P500 G1 F150 X-41.299 Y104.786 Z2 E110.33938 G1 F324.5 X-41.051 Y96.423 Z21.951 E130.34247 G1 F300 X-45.701 Y98.237 E135.33377 G1 X-64.303 Y105.495 Z1 E164.27609 G4 P500 G1 F150 X-64.303 Y105.495 Z2 E166.27609 G1 F322.7 X-62.94 Y97.041 Z21.952 E186.45901 G1 F300 X-68.124 Y96.723 E191.65275 G1 X-88.862 Y95.45 Z1 E221.15989 etc......... made a new machine in Cura 2.4 Delta style, entered the size and settings, the start and end code from the old Cura. Is there something else to change? This thing is big and I don't want a big mess...

these are great for sanding the irregular surfaces, with normal PLA, beware of speed/heat. Available in different numbers (fine/course), I like the yellow.
