![]() In a spherical object, the perceived print quality is "best" near the center of the sphere where the layer edges are very close. In a straight-walled object, the perceived "print quality" is identical from top to bottom. It takes considerably longer but is potentially a more accurate approach and there is no danger of disturbing the bed level.I have seen other slicers with something similar to what he is describing. ![]() I normally use the z-offset to achieve the same thing. I have only done this once but it is a quick way of getting it correct and is quite a nice method. Personally I would use something with a larger base – just take a cube and modify the x/y dimensions and set z to 0.3. I would suggest you use those settings in Cura and then adjust the nozzle width distance with the screws whilst it is printing to get it right. If I look at you pics I would say that all of them are quite poor, possibly in the last pic the print on the left is almost there in the extreme top left corner. Lol I will probably get flamed now but for me these type of settings are just used to hide the fact that you have a problem with your printer setup and I would rather fix the setup than mask it. #Simplify3d adaptive layers code#In Cura if you set a 1st layer of 0.3 the print bed is lowered 0.3 before starting the print so my view would be that there HAS to be more material extruded – but I did not write the code so who knows!ġ st layer width is a fairly recent option added to Cura but I have never used it as I rarely get a problems with the 1 st layer – for me normally a sign that bed levelling and /or nozzle bed distance need tuning. All I will say is that it has always been my understanding that if you set the first layer to a thicker resolution you will get more material extruded. Hi Bjorn, sorry for my misinterpretation of “Primary”, it was late when I saw your post! I do not know Simpl圓D so cannot comment really. I must oversee something really basic I think. 3 layer thickness, although the lines still don't connect entirely. In Cura I'm getting reasonable results with a. 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). 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. #Simplify3d adaptive layers manual#In the Simplif圓D 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. In my last example photo above I was printing at 0.1mm, with first layer thickness at 200%, so 0.2mm. In simplif圓D 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. My examples are about slicing in Simplif圓D. I think though that what you describe in your first paragraph is about cura? I have Cura at 0.3mm first layer. So you need to wait and use a digital thermometer to measure the bed before starting the print. the perimeters of the bed can be 10-15c cooler. On my printer when the centre of the bed reaches the desired temp. And if you are printing something with a large base, say 50% of the build plate, remember that it takes time with most printers t get the entire bed up to the required temp. settings to get the glass up to the required temp. On my printer I add 8 or 9 degrees to the bed temp. of the glass plate (they will be different). monitor is almost certainly measuring the bed temp. ![]() If you have a glass plate on your print bed then your printer bed temp. Use 20mm/s for your 1st layer print speed. If I remember rightly you can do this in Slic3r but with Cura you will need to change the bed and extruder temps after the 1st layer manually. I set my bed temp to 65c and then for 2nd and subsequent layers I change it to 60c. I print my 1st layer at a minimum of 210c if the extruder temp I want to use is higher than 210c then I set the 1st layer temp the same as all the other layers. There is no right or wrong answer to the following but with PLA where necessary you can improve your 1st layer adhesion by adding say 5 degrees to your bed temp and extruder temp for the 1st layer. Reset your layer thickness %s and line widths %s back to 100%. You do this under the Advanced tab\ Quality\ initial layer thickness. Far better to use 0.3 for the first layer. bed levelling, nozzle to bed distance and temps. To do this successfully everything else needs to absolutely right, i.e. H Bjorn, Ok your problem really is trying to print the 1st layer at 0.1. ![]()
