It’s probably something I’ve unwittingly done but … I have been playing around trying to light boxes of late, mixed success but that’s another story. Originally the prints started with a colour, lets say blue. Each blue section would print the outline, then fill that area and repeat on the next blue section etc. It did this with all colours in sequence. Then suddenly it’s started printing all the blue outlines, then going back to each section to do the infil, again repeating this for each colour. I’m finding though that bay going back to infil an outline when it’s finished all the outlines I’m getting far more issues where the nozzle is catching on the outline when it returns to fill. (Hope I’m making sense here) I’d like to go back to it doing each section, i.e. do an outline of a section then immediately fill it before moving on to the next section. Any ideas what setting I’ve inadvertently changed?
for example, lets say I was printing the American flag. Before the sudden change it would print say the one red strip then infill it, move onto the next red stripe etc, then change to say blue and repeat. Now it would print all the red stripe outlines first and when it had done that go back and fill each each stripe, so on an so forth for all the colours.
As a general rule, you want to do the outer walls before infill. Infill can be a little irregular where the extruder direction changes. If you do the infill first, the irregularities can be visible on the outer surface. If you do the outer surface first, it’s smooth and cool before the infill can effect it.
Thank you very much for your response but I think you’ve misunderstood the issue. It does indeed print the outer before the fill in that regard but it’s doing all the different outers of that color then going back to fill them all, so I get a bed of several different outlines, when it’s finished that it goes back and does all the infills.
You are describing the normal operation of the printer, why the American flag worked differently is strange but likely due to how it was designed. I could see this coming down to ‘objects’ and ‘parts’, again based on the 3D design.
I think it will be best if you describe the end state issue, there should not be an issue with printing all the outlines and then the infill, but on certain models you may want to change the order of such things as @RocketSled said or even set ‘do not cross wall’ but this is all based on the problem you are experiencing (color bleed?).
So let us know more details and someone will likely be able to help get to the bottom of it.
Thanks for the reply Lenyo. I did actually write out a response but before I clicked send I figured it out (sort of, it’s cured the issue but I don’t understand how/why) Basically I was trying to print a lightbox I’d designed, to fix the rear cover I’d placed some tabs about 8mm in diameter for M3 screw inserts, raised off the face to prevent then showing through when it was lit. At 8mm it didn’t insist on supports as they where incorporated into the wall but I’d increased them to 10mm diameter it needed/wanted supports, as soon as I added them it went back to infilling each outline as it was printed. Not sure of the reasoning behind it but it’s solved my issue for now.
PS, Not cured, the preview in software showed it as I wanted it but it’s printed the same way, so I still have the issue
the small rectangles and circles will eventually fill with white but as you can see it’s done the outline and buggered off else where to do other blue outers before eventually coming back to infill the area. Like I say, I’ve probably unwittingly change something but I don’t know what
