Very ugly overhangs
Hey All!
It feels like I've tried it all but I cannot seem to get my overhangs to print nicely :(. The print on the image is printed with FormFutura rPLA @210 degrees 0.2mm layer height and 0.6mm nozzle (goliath hotend). Printspeed is 300mm/s for outer walls 500mm/s for inner walls, slowing down 50% for 45 degree overhangs (as in picture). I use Orcaslicer and have extra perimeters and reversing on odd perimeters enabled. Fanspeed is 50% (cpap) increasing the fanspeed does not seem to affect performance.
Any tips and tricks?...
Solution:
I was already doing inner/outer perimiters. Thank you for a nudge in the right direction got them printing nicely now after maxing out my fanspeed and increasing the minimum layer time drasticly to 3.5sec. Seems i need some really good auxilery partcooling fans.
Idex torture test
Finally getting my idex online. Did a torture test print and would love some tips for tuning.
Is this just needing to use a prime tower?
Better filament flow tuning?...
Solution:
Prime tower definitely helps. Clearly need to tune belts and IS.
Extrusion(?) issue on round surfaces
See image - Why is this extrusion situation happening?
Left was printed with tree supports (prusaslicer).
Right was printed without supports.
I thought this was one of many issues due to bimetal effect. I upgraded the x-axis with titanium tube, and the problem persists despite the other known issues to have pretty much resolved.

Layer Shifts looking for help
Im getting layer shifts when printing on default settings within Prusaslicer and within the Ratos I have the speed factor down to 60 % and getting constant shifts . Using orca slicer has a better quality but shifts as well. Both softwares are default setting for VCore 4 400mm
Solution:
your Y IS graph is kinda poopoo, but your x is phenomenal???
Anyways, when you go into configurator on ratos, and go into Hardware Selection, make sure you are running in performance mode...
Inconsistent extrusion with ASA
I recently migrated from an lgx lite to an orbiter 2.5 and have been working on dialing in my asa profile using Inland ASA. I printed this bowl, where the lattice work looks mostly clean, but the top and bottoms are inconsistent. I printed this with an Extrusion Multiplier of .86 after running some calibration prints and ensuring my rotation distance was accurate (it was off by about 1%, which I compensated for). Not sure if this is an extrusion multiplier issue or a pressure advance issue, and...
VC4 500 Extrusion Issues with PETG
Seeing some various issues trying to print PETG
Will fill in with addl details shortly...
top layer underextrusion
I have a strange issue,
I just recently setup a new printer vc3.1 300 which is running klipper.
I have no expierence using the klipper system, my other printers use duet boards.
I also decided to start using orcaslicer for this printer just to see how i would like it.

pla vcore4 500 idex
PLA print of benchy at .6 mm noz and defaults for everything. belts and vaoc and such all configured and fall within tolerances. still need to enclose the printer, shakes a lot at default speeds.
i couldn’t get benchy to print with my petg ( cheap no name brand. ) switched to pla and kept fan at default 40-80 percent. is this messy print on the side a fan issue or extrusion multiplier? ( think i had at .98)...
Crash during print: "Lost communication with MCU.
Random disconnection, not sure what is causing the issue, I have been printing 4hours and this happened with no reason.

Underextrusion?
My prints were coming out fine last week and if I print the same gcode now the top layer is always patchy. Anything I print ends up like this, ran some other flow tests and everything seems to be in order but the corners come out weird. I assume the two might be related. I'll also list some other variables I have tried to test.
Nozzle: .4, swapped to fresh one, no difference.
Flow rate: more or less makes no difference.
Temp: more or less makes no Diddy...
It looks like overextrusion but only on certain prints
When I print this 2 color benchy it either fails comletely or when it can finish it looks really bad but when I printed these 4 mounts for the dayspring leds it worked fine, so I think its more likely a software issue. I have no idea what settings I have to change and I already lowered the print speed to 100 mm/s. It also looks like the Z offset is wrong but I recalibrated that a few times already.
The first layer only holds on one side of the bed
Colleagues - I have run out of ideas for a solution
my printer is a Vcore 3.1 AWD
The situation is as follows: in one place the print adheres extremely firmly (it is difficult to tear it off later), while in other places the filament practically does not adhere to the table - it literally just "licks" it. This problem mainly affects large prints, where the differences in adhesion are particularly noticeable.

First layer Perfect everything after that is garbage
Im trying to tune my v minion after installing Ratos 2.1 .I got it setup with a Goliath and a hextruder, but it won't print properly the first layer comes out perfect but after that the layers won't stick, separate and look under extruded. Before that I had it set up on old Ratos with an orbiter and rapido and it printed perfectly. I print the PLA at 240c . Checked e steps tried to print slower but nothing changes.
