Under extrusion with default settings
I'm having soe issues with my freshly rebuilt VC3 Hybrid running on non hybrid mode. I have just re installed RatOS and updated to RC3. I have done the wizard to set it up but right now it seems to be under extruding.
I have an orbiter 2.
Does anyone know why this may be happening? I haven't touched my slicer settings...
First Layer Issues
Hi All,
Could someone help me get my first layer looking correct? I have followed the guides but i am still struggling.
Thank you....

Vcore 4 idex 500, Toolhead trying to move out of range during print..?
I've resliced and tried printing a few times now and part way through the print it errors out. It's an idex print with the second toolhead printing supports.
Move out of range: -59.959 428.374 11.187 [28812.967]
It was on layer 37, I had a quick look and i couldn't see that move in the gcode so could it be in the post processor? I just wanna print my part 😒...
Terrible 1st layer - bad mesh, tape or twisted frame? Vcore 3.1 300
Hi! I've been having this problem for quite a a bit of time: the first layer looks terrible on bigger prints (bigger than a benchy basically), most of the print area is fine but some spots are terribly raised and tend to hit the nozzle causing all sorts of troubles.
I also attached the mesh that leads to these prints: it's a bit bumpy because I tried fixing a lightly twisted frame (around .05 deviation) with tape getting to around .02
Belts have just been replaced and have been tightened (the problem was there before as well), IS has been tested, the rest of the printer is stock apart from the FMMM mod ...

1st Layer - Filament-flow
I started a print, just a plate with 1mm and got this result. It starts quite good in the right corner and becomes worse and worse as it goes on. Parallel the extruder is clicking.
Has anyone please an idea or a suggestion, what to do or to change?...

Anyone experience this?
After the commissioning guide I’ve been
struggling to get any good prints. Am I missing something simple?

-Using Prusa Slicer 2.9.0 with the RatRig profiles (tried the beta profile as well)...

Rough Top Layers
stock 3.1 400, Oribiter V2
Hatchbox Black ABS, 100 bed, 250 hotend
0.2 layer height, 5 top layers (pic on printer), 4 looks fairly identical (pic on desk).
Same result in OrcaSlicer and SuperSlicer

Replaced my hotend, now I can't get a good first layer
I comissioned my V-Core 4 500 CoreXY about a month ago. I had an issue with adhesion which I fixed and the printer was working perfectly! I was getting perfect first layers every print and the quality of the prints was great. Then somthing happened while I wasn't looking and I ended up with a PLA blob wrapped around the cooling fan duct and hotend and turned them into a single object. I printed a new set of cooling components and bought a replacement Rapido 2 UHF and rebuild the toolhead. The printer is working again, but I cannot get a good first layer now. This is a good example.
The only way I can get enough "squish" is to alter the z-offset at the start of the print, but then the nozzle starts to dig into the bed so I then have to keep adjusting the z-offset during the first layer. This then throws off the second layer and the entire print fails. I've re-reun all the commissioning steps including beacon calibration and it didn't get better
I've also tried a Scan Compensation Mesh, but that didn't help either. I've tried heatsoaking the bed and the gantry, but the same issue comes back. Every time, the z-offset starts way too high and I have to adjust it down to get good squish for the brim and walls and start of the infill, then it's too low as the infill progresses and starts digging into the bed again....

VC4 LDO Orbiter 2 Funky Extruder
Getting constant extrusion problems with the kit orbiter 2 as it stalls out. Running a command to extrude 100mm and it works fine but stalls out. Didn’t change or touch the extruder and pressed extrude 100mm again and it works until stalling again lol… any advice on what might be causing this?
Toolhead Vibrating While Idle – Humming Noise
V-Core 4 (Currently coreXY) makes a humming noise and the toolhead vibrates slightly even when idle. The noise stops if I send motors off command. Is this normal? I assume it is not, how can I fix it?
Nozzle wipe
i have a vcore4-400-IDEX
i am currently printing some big models using prusamnent petg-cf it really does stick to the nozzle and i have also had a few failed print because of it. so i need to wipe the nozzle every now and again. Pausing and un-pausing the print does naturally wipe the nozzle with idex nozzel wippers, but there is still conk stuck to the nozzle after it. Id like to automate it and also have it wipe better. Does anyone have any macros for this i can use? or other advice? i was also thinking how do you get it to use the front wipers attached to the front bed arms?...
V-Core 4 IDEX - Y Problem
Hi, i have a problem with my new idex build. X movement on both heads are okay, but if i want to move Y, he moves in Y but also both heads in X.

Vcore 4 500 hybrid new build print help please.
Got so far setting up the first print and see photos please.
Belts tuned as well as I can get.
Resonance tuning done.
Pressure advance done. ...

Later shift maybe?
Just ran into an issue today when tuning my VC4 500. Where the printer almost forgets where it is and starts printing in a off set location.
I've attached a photo. But has anyone ran into this before?...

Turbulence after corners
Hi team,
Have an issue where there’s shadows or turbulence after the printer turns a corner. Is this a IS or too high accel issue? Are their tests I can run to try and nail down the issue?
VCore4 500
PETG or PLA...

Problem with TPU
Hi everyone, I have a problem with my rat rig v core 4 500 0.6 nozzle, when I print the tpu the first print does it without problems while when I send the second one a jam occurs inside the nozzle and it no longer extrudes the filament.. can anyone give me some advice? thanks

ASA Warping issues
Right know i need some Parts Printed out of ASA but i am having some Big Problems with Warping
Any help is welcome...

Prints began to look bad
I've been printing perfectly for a few weeks but recently I noticed I began having issues with infill looking strange and lines looked "wobbly" and now when printing a higher object I noticed the Z stacking is terrible. You can really feel how they don't stack straight.
Any ideas?...

Hybrid 500 bad top layer
Hi,
my v-core 4 500 hybrid (0.6 nozzle) is still giving me problems.
Coming from a warped bed, rusting rails, a replaced heat bed over a dead EBB to not being able to print properly.
I am currently using orca slicer. Settings attached. I am trying to print a few small test pieces. Left one is with 3 top layers and 25% overlap, right with 4 and 30%. Filament is sunlu ABS red.
What am I missing? Pretty sure it is something simple but I have been so distracted with troubleshooting over the last couple of months I literally can't find it. Hence this post, hoping for some help from the community 🙂...
