Different flow but same gcode
Hello, I have the Ratrig v4 500 with an enclosure. I printed these parts out of ABS. Every part is a new print but there was nothing between.
So I printed every time the same gcode but as you see in the pictures the flow looks different. Any ideas ?
(I have the standard configuration of the v4 hybrid, orbiter v2 + rapido uhf 2 plus)

@Xulkal hello again 😁 do you have any ideas what can cause this
Honestly, all of those photos appear to have slightly too high flow. This is typically why you get wavy patterns in different parts of your print.
Or it's possible you didn't heat soak the printer long enough
I heart soak for minimum 30 min
@miklschmidt hello mikl maybe you have an idea too ?
I would actually say the area you circled is the most correct for top layer flow
Yes I looked at it again and this looks great
if you are looking for a super uniform top layer, ironing is your best friend
But the others are too much flow
But they were the same gcode
inconsistent filament diameter, could be the teeth on the oribiter 2.0 vs 2.5, etc
could be slight imperfections in the first layer as well
But first layer I thought is just till the infill a reason
Then it isn’t a reason
I thought not that this is a so big difference I mean on the overextended parts I think there are 2% to much flow
I got a orbiter v2.5 today so I will build it in later and test again
it depends, I've seen bad first layers fuck up infill which then fuck up top layers.
over all your parts look good, just a few small indicators of problems that could come from quite a few different areas.
another possibility is drag on the filament due to ptfe routing
I am by far no expert in 3d printing
I settle a lot for "good enough" and if I need better, I sand / wood putty fill, prime and paint
Yes but what I don’t understand is that it is the same gcode but the result is different
@miklschmidt or @Helge Keck does this have to do anything software related ? Because the flow looks regular on one part so not just on one point under or overextension but on the complete print
Like if I do one with 99% flow and the next with 101%
But then it prints the complete print with this flow
very unlikely
Hmm any idea ?
i assume this comes from slight warping of the part or from the build plate
The part is not warping this I can confirm 100%
What do you mean with the build plate
during the print the part can warp or even the build plate can warp a bit, just a little tiny bit is enough to have this effect on the top layers
the build plate can lift up on the sides
Ah okay I know what you mean but this is not the problem even I have this in the middle of the print not on the side of
it doesnt matter where you have the print located, and sometimes you dont even notice it
so i wouldnt be so sure if this is not the case
But this one is right in the middle and if there it warps then on the side too or not
Any other idea 🤔
I don’t know if this is related here but I tested the z and one time I got 1mm less 🤔
Do you think this is related
