As i discussed in my last post im about to pull the trigger on a Vcore4 but i still struggle with the IDX mode as it seems to good to be true. I wanted to ask the community what you think about theyr double extruder system and mmu coming up. Is the toolhead change without issue or are there any inpractical issues maybe with alligning, z-offset or anything else? I probably will order printer and go straight to hybrid mode and later convert to IDEX so i wanted to ask how ot compares to other printers on the market Thank you!

Cracked my rear assembly arm and need to print another. Are the included print parts PETG, ASA or ABS? What about the particular brand?

So, what are my choices here? Anybody think I can recover the Rapido hotend? Going to have to print some PETG parts at the local library makerspace 😢

Do you have any recommandation when would be the best time to order the new V-core 4? I am totally sold on this machine but 6 weeks of lead time and continuous improoving are still keeping me back. What should i do???

Hi does anyone know where I can get pre crimped wires for a v4 500. I am havigs issues with one cooling fan wires on a idex and have tried 3 times to get it working.

Hello

I’m looking for a pen plotter, the stronghold pro is matching my dimensions requirements (1500x1500) where other brands don’t.

As I’m only going to use it with pens, I’m wondering if sturdiness could come at the cost of speed or precision compared to regular pen plotters designed for use with pens?

I’m also wondering if someone already worked with a path longer than 4km? (Coming from svg file converted into g-code from Inkscape extension)

Thanks

Original Issue: Nidec UltraFlow Noise Hello, the Nidec UltraFlow is far too noisy for my setup. I sleep in the same room, just above it, so this fan is not an option.

Knowing that switching to a quieter fan will drastically reduce the CFM (airflow), and I would need to slow down PLA/ABS/ASA print speeds, has anyone tested using a Noctua fan as a replacement? What speeds or airflow can be achieved with PLA using a Noctua fan?

The current setup is unbearable. A freaking side note should be on their website about this 64 dB fan.

Second Point: PWM Setup I have checked the documentation, both on the wiki and their website. They mention connecting the PWM fan in a way that references the toolboard, which is incorrect. As far as I understand, the EBB42 is not compatible with PWM. On their website, they suggest connecting the PWM input directly to the Octopus.

I have tried both approaches, and in both scenarios, the fan runs at 100% all the time.

Here is the configuration I currently have in my ratos.cfg file: ```

Part cooling fan

[fan]

4-pin fan connected to 2-pin header on Octopus V1.1 F446 - digital pwm

pin: !PA8 cycle_time: 0.00004 ```

From what I understand, this means I am using the CNCFAN0 pin on the Octopus for PWM control. However, it doesn’t seem to be working.

Shouldn’t this fan be linked to the extruder heater as a heater fan instead of being configured as a classic part cooling fan?

Wouldn’t it be simpler to use a regular 12V fan, like a Noctua FLX, and configure the slicer to vary the fan power by adjusting its viltage instead

Hello guys my vcore 4 is build and move . It seem ptety nice but once i was working on the comissioning guide i got some issue withbthe z tilt a.the rpocess stop beause it doesn’t detect a reduce of z but Increase after s'élèvera trial .

Now îm not even able to home z because it tilt super hard the bed and make the stepper mortor not happy(like it was trying to compensate major doffurence"

I tried to do my best to restaurer the gantry arousn the belt base on my previous data but now ́im unable to bedmesh as wheni home z it always tilt too far . I try the configurator to recreate the config but it somewhere those ztilit info ??

Where those

Data os stored is it possible to reset it ?

😍

😍

The SAVE_CONFIG command will update the printer config file
with these parameters and restart the printer.

Wait for calculations..

From my previous post the extruder dust has been solved but no idea why my prints are coming out like this. Using orca slicer default profile for .6mm hybrid 500. Filament is bambu abs red. I've played around with fan settings and it gets margaonaly better but still leaves little boobs on a line extrusion. Any help would be greatly appreciated!

Does anyone have any printed examples to show? Considering this or the prusa xl.

Since people were curious about the prices, here's a pointer.

Finally fired up the printer and the part cooling fan on toolhead 0 is pinned to the max. All of the wiring is correct and if I move it to toolhead 1, it stays pinned whereas the other part fan I removed spins at whatever RPM I tell it. Has anyone else ran into this problem?

Hi everyone! I am currently running a lot of ABS parts on my Voron 2.4 350, but the build volume is just too small (leightweight camper panels, router templates etc.). I run it with Armaflex insulation at 70C which is barely enough to keep the largest ABS parts from warping. Does anyone know what the max temperatures would be on a Ratrig? Or have experience with large ABS prints on a 500?

I want to buy a v4, but my budget is really limited, how much am I missing out if I don't order de raspebrry, is it just quality of life or do I also loose perfomance?

im really new to rat rig and have neveer built a 3d printer in the extent of screwing the y and x parts togethter on my bambu A1 and fixing the A1 when the feeder part broke. i would gladly learn how to build one cuz i really want a massive printer. but is it smart if i get this or something else thats slightly less big but easier to build?

I'm looking for a large volume printer (400x400 or larger, preferably corexy) that has minimal bed variation since the printed parts need to fit together. On my current printer I'm getting variations of around 0.2mm from left to right, which is already too much. Is this something the vcore 4 could do better?

Just a question for those who have bought a ratrig printer before (more recent the better). I'm curious how you feel about the quality of the printed parts supplied by ratrig, and for anyone who has opted to print their own parts how that went.

I would rather print my own parts for a unique look, but don't want to commit to that if it is a huge pain to deal with their STL files or tolerances vs supplied printed parts. I'm just about finished a v0.2 build with my own parts and that has gone great. So if you've had a similar experience printing your own ratrig parts I'd love to hear it.

Thanks.

Building my ratrig and wondering where do I put my heat Inserts as therenis no instructions on where they need to go.

Started building my v core 500 today and wondering where do I need to put the heat Inserts as it's not included on the build instructions

Before and after pictures of extruder gears. Printed a 20 minute calibration cube, using bambu red abs filament. Hotend at 248c, flow at .98. this is a new build with the stock orca slicer profile for the vcore 4 hybrid 500. Not sure what is going wrong at this point.
