Unstable extrusion when a new perimeter starts after unretraction
This is only a cosmetic problem and does not really affect the quality of the parts.
There are no significant underextrusions or overextrusions which would affect the structural integrity of the parts. However, I would like to get a better surface finish for my decorative prints.
The problem:
The external perimeter line starting from the seam has a slightly higher/lower width, which makes a visually unpleasant line. This happens only if the perimeter line started from unretraction....
Print warping
Hey folks. My print is warping as shown in the photo.. using PLA, extruder at 200C and fan art 15 to 30%.. need is at 65C..
All info I've read this far seems to suggest part cooling to fast. Should reduce the part cooling fan lower than 15%??...
Problems with large first Layers
Hey there, my printer is working fine for the most part. but when printing large first layers it looks like in the pictures, i tried reducing flow% already and lower and rais temp but without success. lines on the other hand print fine even 5 or 6 next to each other.
But i gues its still too much extrusion, but if i go much lower other parts get underextrusion...
Printing with ASA on V-Minion
So making some progress with tweaking my settings for ASA. Still trying to figure out the overhangs but at least it stuck to the bed ok this time and finished.
This was sliced with Prusa slicer 2.5 with the stock 0.4 nozzle at 0.2 layer height. PolyLite ASA printed at 255c with bed temp at 108c first layer then 100 for the others. No fan except for bridging at 30%. Running the current RatOS 2.0 on the V-Minion in an enclosure.
Any input or comments would be welcome. Not looking to print ASA all of the time just trying to get it the best I can at the present time....

Heater extruder not heating at expected rate
Hi
I keep getting this message. it has come some times before but i just had to restart an everyting worked fine but now it keeps coming up all the time. i dont know where to start. everything is all new to me with klipper and so on. the heater is a revo voron e3d...
Corner and seam problem
I have a corner (and Seam) Problem on most of my prints (see pictures) Seams show the same behaviour thicker on the breaking side . I am suspecting my pressure advance settings. Did a pressure advance test with the recommended settings from the klipper github but it was quite hard to determine the right value.
Did the Test with a 0,6 Nozzle, 100mm/s and 0,45mm thickness (as recommended 75% of the nozzle diameter), have a Rapido + Orbiter 1.5 installed.
Doesn't that look like the value being too high? Happy for any help!

Print holes between layerszits
First picture is two prints using the same settings first print (right) is mostly fine other than a pressure advance issue. Second print (left) has some nasty seams, what looks like holes between the layers. Second pic has clearer image of uneven layers.
Both printed in pla with a .6mm nozzle at 205 c, 200mm/s speed, 6000mm/s acceleration. Layer height of .48mm.
Any idea what would cause the massive variation between these prints and how to avoid it in the future?...
PLA lithophanes keep clogging
Hi there, I have a "standard" rápido with a cht .4, standard fan, and lgx, mostly standard pla superslicer profile.... I print play parts with no problem but when it comes to lithophanes looks like heat creep.... Any ideas?
wavy corners
this print (after rebuilding my VCore 3.1 300) has some issues. My question is about the wavy corners.
Input Shaper is tuned. I have this with all filaments, no matter fan or temp settings - so probably no pressure advance problem. This is the 3Do Ratrig green ASA filament with the ootb SuperSlicer settings.
What can I look out for?...
Top of print has holes
What's going on here? Why does every time I print a dome, the top looks like this? Happens at the same layer every time despite changing a variety of settings.
Terrible stringing with PETG on neptune 3
I've been printing some honeycomb shelving/organizing units on my Elegoo neptune 3 (bowden) and Anycubic Kobra (direct) using overture black petg (same package opened at the same time) . The kobra has been printing flawlessly, but the neptune hasn't had a clean print yet and most of the stringing and blobs are so bad the parts are unusable.
I've lowered the temp to 225 (brand rage is 230-250, kobra prints at 240), had speeds between 40 and 60mm/s, retraction at up to 8mm at 40-70mm/s, z hop is off, I've switched between prusaslicer and cura, but the results are the same every time. I've run temperature towers, retraction tests, all that.
I've noticed it does not seem to start getting bad until around 30% of the print but once it starts it just gets worse and worse....
4mm Z distance lines (compressed layer)
Although not so obvoius they are there at a fixed interval in Z.
I tried to recalculate from where this 4 mm comes from.
If I know it would be easy to solve 😀 .
Happens with all filaments also on long objects all around so it must be in the Z system.
Screws are checked and the regular 4 mm distance makes it repeatable and not random....
First PETG benchy is not the best. Any tips?
The benchy's hull looks pretty rough, theres a big gash you can see on the starboard side (possibly an adhesion/cohesion issue?)
Theres also some ugliness with any bridging, and generally some bits of filament stuck in places they maybe shouldnt be.
The benchy's deck, roof, and smokestack all look good....
