Hi I hope someone can help
I am printing somthing that is only 3 layers deep using the generic PLA setting
1st layer prints great but 2nd and 3rd layers print extremly fast
what setting do I need to change to enable the 2nd and 3rd layers to print at the same speed as the first
thanks in advance
Dave
The speed of a layer is split into different regions (e.g. outer wall, inner wall, infill, etc.); thus, to print at the same speed, you need to define the speed of these zones identically to the first layer. Acceleration is also crucial.
You may also limit the printing speed in the filament itself by, for example, setting a minimum layer time.
Why do you say too fast? Does it fail?
The best solution is to customize specific zones printing speed to achieve the desired output. Note that such a drastic speed reduction in all the print area may result in other issues. E.g. you may need to lower the printing temperature to avoid over-extrusion.
Thank you for that information
I’m creating some colour badges which I can do as a single layer But Its not really dence enough I will work with 2/3 layers but because it starts to lift at the normal 2nd layer speed I want to see what happens when I slow the second and 3rd layers down
You need to tune your filaments. You’re under extruding in a big way. The part probably lifts after 1 layer because the first layer isn’t really stuck down to the build plate.
You shouldn’t see any of the gaps, like are so evident in the green, but are pretty much present in most other areas.
At first, I thought this was a Needle Point.
I agree with @RocketSled, as filament tuning is the best option.
As the top surface is planar, you may improve quickly by ironing or increasing the upper surface flow (110% to 150%).
Regarding speed, I am unaware of the part dimensions, but I would reduce the outer wall and top surface to 120/100 mmm/s. If ironing, you can discard the top surface speed reduction.
Another thing, with only three layers, the surface pattern may play a critical role, so you can try to play with this.
Also, this is the king of print, where small layers and a 0.2mm nozzle are a must.
Hi thanks for your help JayZay & Rocketsled
Im almost there Just need some the correct colour filament and a little tweeking
.2 nozzle and 4 layers multicolour without AMS
Uouh… it is indeed a completely different print. You made considerable improvements on that surface. The green comes quite pleasingly.
Glad to hear and see that you are on the right track.
Don’t get me wrong, the print is excellent, but I notice a minor detail that is fixable.
It seems that the white is stained with black filament. The cause is either a low flushing volume or a solid black layer below the white.
The first already happened to me, as I was looking to minimise filament waste; black to white requires the highest flushing volumes to achieve a clean print, and I don’t know any workaround.
If the cause is the latter, you either increase the number of white layers or, in a more ambitious method, you may try to set the g-code for thicker white lines in the top surface manually.
Green looks good. Red looks good. Black looks good. Tan looks good. White looks like it’s still underextruding. But this is vastly improved. Nice job. Almost there!
Hi thanks for responding with your very helpful suggestions
Yes the only white I had was silk so I have ordered some new colours
Thanks again Dave
