Idex T1 very different print quality
My T1 extruder (orange) produces very different results from T0 (black). Even when swapping filament, the results remain the same. Any suggestions as to where to look would be greatly appreciated.
Thank you...

Perfect First layer, disasterous second
Hello,
My first layer is almost perfect but the second is an absolut mess.
The building plate is preheted to avoid temperatur issues also tried different slicer settings. But it seems ratos shifts the second layer. Does anyone know how to solve this issue?...

Bumpy edges on skew calibration
I’m trying to dial in my filament before officially putting in my skew calibration. I did all the calibration tests on orca. Tried a lot of things but can’t get rid of these bumpy edges. If anyone can point me in the right direction that’d be awesome.
If you’d like my filament and printer settings lmk. Otherwise I’m hoping it’s a common issue to fix. Tried google but couldn’t really find anything that matches. It is not z wobble btw. It’s not consistent and doesn’t show up on more organic prints....

IDEX Underextrusion
Anyone else seen this issue? VC4 500 IDEX setup and overall print looks good, except for pretty bad Underextrusion in areas of the print where the amount of filament laid down is relatively small...even with 1.0 extrusion multipliers, dry filament, reasonably fast speeds (300-450), and PA completely disabled. It's as though I'm losing nozzle pressure during the time it's parked and so it takes a little while to recover with proper flow. Thoughts??

Holes in Infill
I am running PA tuning right now with 15% infill and i discovered something that looks like underextrusion in the infill. Anyone has an idea what could be the cause?
I am using PLA for printing and am kinda struggling to get consistent and good results...

v-core 4 dragging nozzle through print
I've built a ratrig v-core 4 IDEX and have mostly completed the commissioning guide. Mostly, the printer appears to be working. Problems arise however, when I start printing.
The first layer goes down a treat and the second one looks OK too. But after that, the printer appears to be dragging the nozzle through the print. I can see the lower layers compress as the nozzle is laying down the next one. After stopping the print, I can see nozzle shaped indents all over the last layer.
I figured maybe something is wrong with a Z axis multiplier of some sort. But when moving the build plate 100mm up or down and measuring with a ruler, the movement distance appears correct....
One color printing just slightly smaller on T1
What would cause my green to print just slightly smaller than the pink?
Other than this minor issue the IDEX is printing flawlessly 😀...

Dialing in ABS Settings
Im currently trying to dial in my settings on Hatchbox ABS. My bed temps are at 100C. Nozzle is at 225 for the first layer and 220 for the rest. Im fairly happy with the left side of the benchy but the right side seems rough. Im not sure if this is because of how the benchy is layed out in the slicer. The side that is rough is facing towards the back of the printer. Im not sure if I should continue to crank up the fan speed or lower the nozzle temp. I also attached my fan speed settings.

1mm Nozzle Seam Issues
I decided to try a 1mm nozzle on my VC4 and I'm really happy with how I've been able to get it dialed in, except for the seams. On the outer walls, I'm getting scaring (under extrusion) and on the inner walls I'm getting blobs. This is with Sunlu's High Speed PETG, using OrcaSlicer.
I've played around with retraction settings a bunch, and I've been able to improve the issue by bringing retraction down to 0.05mm (tried a range from .8mm to .05mm) and keeping extra length on restart at 0mm (tried a range from .8mm to 0mm), but I can't seem to solve the outer wall holes without making the inner seams significantly worse.
I have calibrated my flow, temp, and max flow rate using OrcaSlicer's calibrations, and I've disabled pressure advance for the time being....
Seam has consistent blob but not sure how to remove it
Machine: Core v4 500, toro tube and chube, 0.4 nozzle
External walls printed at 150mm/s with scarf
ASA material
What i've noticed is that the printer will sit at the seam for a split second which causes a smidge of oozing. I'm not at all sure what is causing it to sit at the seam but past that all other paramters appear great. the finish is good, layers are smooth. dimensions are within acceptable range for holes....
Non-ringing artifacts - what is it?
I'm getting these weird vertical lines in my prints, both in X and Y. After doing a klipper ringing tower test, I can conclude that they have the same frequency as the machine's ringing effect, but they're still there even after applying resonance compensation.
The first pic attached has resonance compensation turned off, and the second has resonance compensation (MZV) turned on. Ringing gone, vertical lines still there, both in X and Y...
Does anyone have any idea?...

Wavy Lines on X Axis
Hi guys, still fighting this dang printer. Finally getting to print some things and I’m running into issues with wavy lines on my X axis, particularly after a corner. See attached photos. I’ve checked my belt resonances and set my acceleration to the recommended amount but still have this issue. This is after all calibration flow, PA, temp, fans, etc. I’m also getting some slight under extrusion. Even after calibration flow and PA. HELP!
Solution:
Did you add the correct number? I’m away from my printer but I’m thinking mine was like 47.8 or something similar. I’m also setup for Idex.

Help with first layer - vcore 4 hybrid 500 new build
I cannot get my frist layer no matter what I try. I think the nozzle is to close to the bed. Did the beacon calibrate about 20 times. Am I missing something?

How can I reduce effects on the corners
I’m convinced this is something related to speed because this is a non issue when I am running low velocity and low acceleration but at higher velocities and acceleration it creeps up

Preheat Toolhead before Toolchange
I am able to set a standby temperature in the ratos config of the vcore 4 idex, but is there no way to make the toolhead preheat the nozzle before it needs to be used? I always have to wait 15-30sec before the printer is ready to print again.
If I use the "ooze prevention" function in orca slicer the toolhead is correctly preheated, but I have to wait till the not used toolhead to reach the standby temperature.
I imagine it would be a quite easy implementation in ratos to set variable preheat parameter.
If anyone got a soluton for that I would be very thankful 🙂...
Weird (PA?) artefacts on an arc movement. VC4 500IDEX
ASA print with 0.6 hardened nozzle. One long side is straight and has no problems, the other has very slight radius and I could even hear how toolhead is slowing down.
PA 0.04, max speed 120mm/s. acc 2k...
Solution:
Found, arachne was to blame, PS 2.9.0. Switched to classic and problem is gone
ABS bad layer stacking and overhangs
I’m having some issues with ABS and not sure where to begin. The corners looks aweful but overhangs above look okay, probably the corners warped a little bit during print but don’t think that’s the whole truth.
I’m also not very happy with how the layers are stacking , if you zoom the pictures you can see the layers is not consistent. You can see some ”ghosting”. I’ve shapers set correctly and pretty clean graphs
I’m thinking if it could be extrusion temp? ...

portions of vertically printed cylinder print not smooth
When I print a vertical cylinder, the front and back sides of the cylinder (what you would see if you looked at it from the front or back of the printer) are perfectly smooth. But if you viewed the cylinder from either side of the printer the sides have a very slight wave to them. So sides when the toolhead is running mostly in the Y direction are not smooth and sides where the toolhead is running mostly in the X direction are perfect. It's an idex machine and this happens with either toolhead....
Line in the middle of every print?
I'm sure i saw a post regarding this problem in the past.... I'm using cura as my slicer. Every print i do I have a distinct line kind of in the middle of the print. It is especially evident when making lithopanes. Does anyone know if there's a setting in cura that needs changing ? If I can figure out how to attach a pic I will

Generally great print quality except this curve?
I redone my belts with the GATS system tensioning my belts equally across all 4 of them to approximately 4kg, and made the belts equal size. The belt tension feel's lower than I'd of done it to manually. Whilst doing this I re-squared my gantry too which has improved my VAOC results. Overall my machine moves as smooth as it ever has but..
I'm getting this bumpy, wavy wall on what should be a smooth curve though?
Any help greatly appreciated...
