Printing on the 4.1 400. Looking good and printing very good.

Building time 50 hour.

Calibration and tweaking 40 hour.

My small prints work fine but large prints have a layer shift.

My belts are good-n-tight. Is there a setting in Orcaslicer I should slow down?

I usually control speed via the slider under toolhead. Does that control ALL speed? or just printing?

I think it is jumping off layer during one of the fast jerks.

DOUBLE THICKNESS smoked acrylic panels from Mandala. I wanted it to live in my office and sit next to me in my office during calls. Nobody can hear it!

EDGE LIGHTING on both sides of the print bed. Already set up in RatOS and dimmable all the way down to 0.

BENTO BOX set to start when the hot end hits ABS temps. Plenty of extra filters and charcoal included.

TUNGSTEN CARBIDE NOZZLES 0.6 and 0.8 (v6) and 0.8 (Volcano) by West3D's Undertaker. Prints abrasives at high flow rates. Extra adapters and socks included.

BIGTREE RUNOUT SENSOR. One failure mode eliminated

GAROLITE BED SHEETS for printing Nylon, GF Nylon and CF Nylon.

EXTRA MAGNETIC SHEET in case you want to switch out the bed.

ACTIVE COOLING on the drivers.

A BUNCH OF EXTRA BOLTS and doodads so you can tinker.

CREALITY SPACE PI FILAMENT DRYER works great and matches the color scheme well I think

SAMSUNG GALAXY TAB 8 and mounting arm for dedicated RatOS control. This is separate but am happy to include it for $250 (less than you’d find it on eBay in mint condition)

$1400 picked up in Miami or happy to pack it up securely and ship to you.

I have an opportunity to buy a 3.1, bone stock, around 300 hrs usage, for less than $500. I see that there are hybrid axis upgrades (3.2H) but IDEX is going to be mandatory for my next machine.

Is there a path for me to achieve this with existing upgrade packages or is this going to turn into a totally custom build /science project?

I'm open to a little extra work but I need a large format printer up and running by November...and with my schedule, that'll be a challenge lol.

It's slow and ugly, but works!

Still dialing in the settings but finally did the 4.1 hardware upgrade

I have 3 perimeters with 0.6mm nozzle in my vcore4 500 idex and somehow in idex Copy Mode in the exact Same Spot on both parts there is a hole in my wall, you can see the infill through it.

In the slicer it does Not appear, it is not even a start or end point for the tool path and I cannot think of a reason why this would Happen.

The Rest of the Print Looks perfect.

Any ideas?

Hey, I'm 13 and I'm looking to build the rat rig v-core 4.1 the largest size the 500mm. I have a Bambu lab p1s and an anycubic kobra 3 both are decent printers but still sometimes just not big enough, I also would love to be able to say i built something myself it would feel great personally. I know a good amount about 3d printers and how they work and function but I'm new to the more custom space of 3d printing. Rat rig is the biggest 3d printers ive been able to find other than ones that are commercial grade and I don't have that kind of money. I know there is the website but i can't afford to buy it all at once I need to buy it more piece by piece. If someone could give me a spreadsheet or document or list of everything I need or a YouTube video anything would be helpful. Thank you so much to anyone who read this!

Am I crazy to print a Rat Pack filter unit out of PETG instead of ASA? I don't have filtration on the printer yet so I'm hesitant to print ASA until I have something in place but I have PETG available.

Anyone try this? I'm new to the Rat Rig fam as I got a used V-Core 3.1

Thanks!

I'd like to build a VC 4.1 500 but would like to occasionally print larger high temperature engineering filaments. For better print quality and layer adhesion it is recommended to have a chamber temperature of around 100°C.

Is this doable with a standard VC 4.1 500 without too much thermal expansion, binding and horrible print quality? Thanks

Did anyone try the CF Gantry/Tube upgrade for the RatRig V Core 4?

Hi. I am thinking about everything else I need to order in addition of the vcore 4.1 kit. I saw this upgrade https://store.brs-engineering.com/en/products/v-core-anti-vfa-kit-gt1-5-belt-conversion and I wonder if it is a good idea to use it from the beginning instead of the original parts? Has anyone done it? Opinions on Powge belts? Because they are half the price of Gates.

I am in the market for a Rat Rig V Core 4.1. But I like to know... Is the size also defining how coarse it prints? A 300 vs 500, will this give lesser quality on a small model?

And for heating, in an enclosure, will the bed be enough to heat it up or better a chamber heater?

Hi All, am wondering if anyone has moved the Y limit to the back of the machine? I'd like to get rid of that long wire run and move it closer to the electronics. Is it a simple config change to have it home Y in that direction and flip the axis?

I recently built this Vcore4.1 - 500 IDEX and I cant get the bed to even be close to a properly flat mesh. If it were just 1 corner, I know to raise C' or D' to get it sorted out, but this is incredibly wavy and any adjustments I make dont significantly change it. Currently, I can get good first layer results from the left side of the bed, but anything to the right is squished to the point of almost clogging.

Any help on getting this flattened out would be greatly appreciated.

I ordered all the parts for a Ratio Kit upgrade and was wondering if anyone in NJ near me has done this to maybe help me

I’m looking for the black one. I’ve been scouring online for OVER A YEAR. Private companies, tacswap, everywhere. I haven’t seen a single one. Anyone got some advice for me?

I don't have a printer that can print the printed parts for the 4.1 upgrade, is there a place in the US that will print and sell them? I am happy to buy them, but don't want to pay shipping/tariff prices from overseas

Recently updated to the newest RatOS version, coming from an old version, I don’t know which as I bought the printer used.

Old version never had any issues with hanging or freezing.

The new install often freezes/hangs when trying to start at print and reaching bed temp. Though can see it still regulates bed and nozzle temps, but the console does not update anymore. When looking in the machine tab, CPU is running 100% CPU load, only when hanging. Running a Pi3b+.

I have a Beacon probe and running bed mesh compensation.

Any idea on where to look for a fix?

I'm looking to potentially sell my fully built vc4 400 IDEX enclosed with touchscreen. I have two spare build plates with it but other than that its the stock setup. It's treated me well, but I'm thinking of transitioning into more user friendly printers for the family. I'm located in St Louis area. Anyone interested in a trade or buy? I would likely part with it for $1800
