The lines are reaching the shell ok Thanks for the graph link, that is useful!

The intercooler was printed at 0.1mm layers, 210c and 20mm/s but still had some gaps between the layer lines, the first intercooler I printed looked a lot better and I used the same settings The blind bracket was 0.2mm layers, 220c, 50mm/s and this is where the line gaps seemed worse, so it's all about balance really and how much material it can put down You don't think this is any mechanical problem then like belt tensions? I'm using the filament that came with the printer, the 2.85mm PLA blue, settings set to 2.85mm

Nico, Did you manage to fix this problem?

on most of the layers on the intercooler the lines were not touching I snapped a bracket on my blind last night so decided to make a new one, works brilliantly! I am loving this Printer, just a few small problems to over come along the way I guess There were a lot of lines not touching on this print, I had to revise the design after the print shown below as I needed a square hole in the centre and not a round one to stop the blind shaft from rotating and the blind just dropping down on it's own, printed this at 0.2mm layers, 220c, 60c bed, 50mm/s, fill 50%, this was after tightening the small belts, is this under extrusion?

Just did another print and the layer lines were not touching, so I loosened the stepper motor screws and pushed them down and retightened, managed to round off one of the hex screw heads, I'm not keen on hex screws, I'd like to change those to normal screws, do you happen to know if they are M3?

Think I may have nailed it

It shows the tool path and the grill layers and still printed flat on top, and the one with the indent is also weird, why would it totally ignore the grill lines and just did the indent part Just loaded the file I shared in to Cura, if I look at layer view without scaling it up, it shows the layers for the grill lines but no tool path, if I scale it up my 2.0 it then shows the blue tool paths

I did check the layer view and it showed the grill layers but still printed that face flat, and on another design it printed an indent but didn't do the grill lines, as shown in my previous small test prints, still can't work out why

Everything is the same, apart from one thing, the top and bottom layer thickness, mine was on 0.3, may be this is why it cut off the top and made it flat on mine, it didn't go high enough? Your slice image looks the same as mine. I did scale it up a little when printing mine, as it wasn't quite the correct size that I needed.

How did you do this? haha Nozzle was set to 0.4 just doubled checked The one in my test prints where it shows the grill lines is a different file, the one I shared is the one I'd like to print so that the grill lines are flush with the top surface Are you using Cura or some other software? if you are using Cura then you must have different settings in there than mine Thanks for taking the time to help me, I appreciate it!!

Tried netfabb, still doesn't print the grill bit Here is the stl file https://www.sendspace.com/file/n42yas

Still can't get the front grill right, I did some different designs, but none came out how I'd like it to be when doing the grill area I drew a retangle pushed that down into the front face, then drew lots of lines across that retangle and pulled them up to create the grill effect, when I printed it, it was just flat on the top, so I then tried to make the grill part seperate and join the two parts together to make one solid component, printed that and still didn't work how I wanted it, I must be doing something wrong in sketchup, should I be working it metres or mm? if I work in metres I will need to scale it down in Cura did these small prints below just to test, one has an indent and none of the grill lines printed can anyone help before I rip my hair out? :(

It shows the top grill in layer view, I think the problem is, cure is treating that whole top layer as one thing, and when I printed the first one, the top and bottom layer thickness was greated, and that's why it just about managed to print a bit of the grill on the first one. I think I need to make the grill as a seperate solid component in sketchup and join that to the main part, I think haha

Ok will do thanks, next job is trying to work out why it didn't print the top grill part, just looking at the files at the moment

30mm/s, 205c, 60c bed, 0.1mm layers, initial layer thickness 0.3mm, ultimate blue pla

Changed the design and changed some settings and seems to be a much better print, but it did not print the top grill part, how weird! must be something wrong with my stl file hmmm Also has a pretty much constant ticking sound when printing this, I'm sure it was coming from the feeder

Ok will try that, thank you

I was printing at 200c, bed was 70c, speed 30mm/s, weird really as I printed a phone case before this and it printed fine, may be it's my design that's a bit strange, I've done a revised design so will try that I have fans set to come on at 5mm 100%, do I need to adjust this? Whats the best option/s to reduce over extrusion?

I'd say yes the layer view does reflect the print, apart from the top edges, with the layers sticking out

There was no overhang on the top edges though but still seems to stick out

Thanks very much for the replies, I will give those ideas a try, I like the idea of printing the cylinders separately and gluing them in to holes on the main part. Can I ask, why do the top layers also stick outwards at the egdes?

Hi Bez, I have been reading that guide already, very useful! I was wondering if I can improve the end cylinder parts by design improvement instead of may be tweaking printer settings alone?

I am wondering how I can improve this print, this is the first thing I have designed myself and then printed, it is a small intercooler model for my RC car Looks ok from the top, but the end round bits are not too good at the lower half, they were bending up during printing, a bit like the ultimaker robot ears seem to do sometimes, the first layer is squashed out due to the bed level, but the top layers seem to stick out at the edges as well? my main concern is how to get the end cylinder bits to print properly? Also the bottom looks a bit weird as well, may be under extruded?

Still have a fan problem, I am printing something as I write this, one fan started spinning very slowly and the other one was not moving, I waited for a few mins, still not spinning, so I pushed it around with my finger and then it started spinning on its own, does this sound like a faulty fan then? When I test when with the fan speed control on the menu they seem ok
