Weird plastic blobs showing up everywhere
I have been having these random blobs of plastic showing up all over the build plate and also the print which can cause the nozzle to crash into it. It doesn't appear to be dripping around the nozzle from improper tightness. What could be causing this?
Retraction calibration help
After changing my hot end, I started running a reaction tower, changing retraction length by 0.01mm per layer starting from 0 and going all the way to 2.65mm nothing seems to have changed. PetG, 230c, retract speed 60mm/s.
I haven't yet tuned for PA...
Layer skip
Hi,
Can someone help me with some tips on how to solve this problem?

Thanks!...
still tuning. retraction issue?
Stock v-minion.

Help with slicer
Is there any way to tell the slicer to avoid these travel moves? I've enabled 'avoid crossing perimeters' but that made no change. Having some difficulty getting a clean print due to these unnecessary movements. Using SS.
new filament, gaps in layers
Printer has been working great.
I changed from esun PLA+ to PrintedSolid Jessie PLA.
I am using the default settings in superslicer for ratrig PLA.

Filament runout/restarting woes
This is my first print trying to use a filament runout switch to restart a print.
Once the print paused, I simply loaded a new spool and used the 'load filament' macro in RatOS.
After the printer nozzle was extruding and the load sequence ended, I clicked 'resume'.
The printer restarted, but did not adhere to the print....
ASA Top Layer woes
Video here: https://youtu.be/BZIWREPE9lg
Top layer is absolute garbage. My problems start with the first solid infill layer, where you can see it is already bad. After that, it just piles on till it reaches the end and has a coarse surface. I have set the Extrusion Multiplier. The flow rate test has been run time and time again. Results always point to best results between 0.96 and 1.00. I have tried to change bridge flow to 0.8 and bridge density down to 75%. Still no go. Pressure Advance is also good.
You can even hear the printer scratching the surface of the previous layers. ...
stringing
Hi everyone,
I have an issue with the stringing.
V-core 3.1 400mm enclosed.
This filament is asa from Polymaker
The temp tower has stringing everywhere. I tried from 0.4 mm to 1mm but same result. Is this a problem from the slicer ? From the extruder ? The hotend? ...
Banding
Just finished setting up the v-minion and im getting this banding. Tried loosening the x-axis belt but no luck. Any ideas?
Is this a firmware, slicer, hardware or model issue?
I have a VCore 400 which is working fine, I mostly print usable stuff but for a change I purchased a design model to see how it would come out.
It didn't come out very well, it has this almost "fuzzy skin" going on, on the pictures it's exaggerated as it's zoomed in and under harsh light but you can clearly see what I mean.
I thought it could be Pressure Advance so I turned that off and re-printed the base but as you can see in one picture those two models are nearly identical so it's no PA....
Settings change mid brim?
The first two lines of brim are probably the best 1st layer I've ever put down. On the third line it all goes out the window. It's not like the brim is over, just checked Cura and brim line count is set to 20.
And it's the whole way around the 300mm build plate. So it's not a level issue. Have y'all ever seen anything like that before? Wonder if that's part of why my prints keep failing....
PetG Looks like crap
Never had much luck with PetG. Everyone else says it's easy. "Overture" brand.
Ratrig 3.0, using Superslicer w/PetG generic profile; defaults except 3 perimeters and a small brim. (extr: 240/235, bed: 80/80, infill 15%)
Note that the side arms start looking quite a bit better once the layers get above the 'busy' part of the model....
X axis shift
Hi guys, on long prints (50 hour ) roughtly 50% of the time i am getting a 0.5mm-1mm layer shift on the XAaxis, that stays shifted. it tends to happen about mid print, but not at the same height. What could this be?
strange pattern at top of print.
Hey guys,
I am printing an iron man helmet for my son. Today I tried to print the face. I used geetech silk PLA @215C. I printed pretty slow, and the lower half looks good.
But on the upper half I am getting strange patterns. Can this be over extrusion? But why wouldn’t it show up at the lower part as well?
The inside of the mask looks great though…...
