Are you looking to buy a Rat Rig 300mm V-Core 3.1 Standard Kit in Australia?

The V-Core 3 is a premium DIY kit for a CoreXY 3D Printer with no compromises. Learn everything about the V-Core 3 on the dedicated project page: v-core.ratrig.com.

Our kit includes ASA Rat Rig in house printed parts and also includes 1 bag of 50pcs M3xD4.6xL4 Threaded Knurled Heatset Inserts - You will require around 45 of these to install the EVA Toolhead.

We sell this kit with the included new Enclosure 2.0 as we assume you will want this to print ABS temps and beyond. Although it includes Enclosure 2.0 this does not mean panels are included so there are a few options for customers on how you build the kit.

Option 1 - You don't use panels to mount your electronics. Rat Rig did this for all their production builds so it's definitely possible however for ease of building we do not recommend this option.

Option 2 - You self-source your own panels

Option 3 - You buy our Rat Rig 3.1 Electonic Panels in Black Acrylic 3mm, and mount your electronics to the acrylic. It comes in four pieces (split panels) so that it can ship with your kit in the same box. (Full-size panel does not fit in for transit) - Please note there is a 1 week lead time before we ship as they are cut to order and we will ship this WITH YOUR 3.1 KIT (1 wk delay) Also note that if you are going for a full enclosure for ABS/ASA etc you should consider Option 4, not this one.

Option 4 - You purchase our full Rat Rig Polycarbonate Panel Kit - 4mm which includes the whole panel kit which has the full-size electronics panel required. ETA is May 2023 for delivery on this panel kit, we will ship it separately to your 3.1 Kit.

WARNING: This build requires a Raspberry Pi, but the kit currently doesn't include one!

--------------------------------------------------------------------------------------
Before buying this kit please note the following disclaimers/information.
--------------------------------------------------------------------------------------

  1. If you have never touched a 3D printer, do not buy this kit.
  2. This is a significant project/build to undertake. DC electronics, advanced 3D printer knowledge is recommended. It is assumed you know how to crimp cables, own a crimper. Experienced Rat Rig builders take 25-30 hours to complete a build. It's not uncommon for first-time builders to be taking 40-50 hours before everything is complete and ready to print.
  3. It is recommended you read the assembly manual in completion before committing to purchase and build a kit.
  4. Please note that we do not provide technical / building support via phone - We only support questions/support via email & discord.

This "Standard Kit" is meant for users who are unsure about which configuration options to choose, and are above all else interested in acquiring a kit as complete as possible, including all necessary electronics, and with proper documentation to guide them from beginning to end. If you're not feeling particularly adventurous, this is the V-Core 3 "walled garden" - this is where we recommend you should stay if you're just starting out and need someone to hold your hand and show you the way! ;)

The default configuration only lets you choose your desired build volume. For each build volume, this is what you are buying when you add this item to your cart:

  • - 1x Rat Rig V-Core 3 (Mechanical Kit)
  • - 1x BTT Octopus v1.1 + 6 x 2209 Drivers
  • - 1x Phaetus Rapido UHF Hotend - Black - 1.75mm - 24V

NOT INCLUDED

We're working to get there, but for now, the default configuration is not the same as a turn-key, complete kit. Some items will need to be sourced elsewhere.

  • - Power cord - you will need to source a power cord with a plug, to connect your machine to the wall. We don't supply them since we ship worldwide and different countries use different plug types.
  • - Extra printed parts (LAN/IEC adapter, back-spine/nut/colar for cable routing on the electronics panel) - these cable management parts are non-essential and can be printed later.
  • - IEC/Lan Plug - these are optional, and need to be user sourced.
  • - Cable crimping - you may need a crimping tool to assemble your electronics. Learn more about cable crimping here.
  • - Fasteners to mount electronics to back panel (8 generic nylon spacers are included for this purpose, though)
  • - Depending on machine size and where you want to install the controller board, extension cables may be needed for the following components: BLTouch, SuperPinda, hotend heater and thermistor, limit switches - these components ship with short cables, and at the moment we do not stock extensions for them. We recommend sourcing the following cables:

To extend the cabling of your bltouch:
1x 22AWG Cable 5 Conductors 1500mm
To connect PSU, SSR and board:
3x 16AWG Cable 2 Conductors 500mm

Works well. You need to drill a 3/8” hole
Appears to be well made, alignment bar slides in nicely. As stated, you need to drill a hole in the bar for the gimble bearing driver, the directions are not clear, what I did was before I take out the old gimble bearing, put an O ring on the bar close to the last step on the bar, slide the bar all the way in, then carefully slide the bar out, this marks the distance from the back of the gimble bearing to where the shaft on the outdrive bottoms out, move the O ring a 1/4” towards the stepped part of the alignment tool (this is so you won’t bottom out the alignment tool when driving the gimble bearing in) then slide the driver puck up to the O ring and use a 3/8” diameter transfer punch through the side hole in the puck to mark the bar. You need to drill a 3/8” diameter hole in the alignment bar, two V blocks, some clamps, and a drill press will make drilling much easier, after the bar is securely mounted and centered in the drill press, use a center drill, then 1/4” drill first, using plenty of oil, drill all the way through, then use the 3/8” drill, deburr both sides and you should be good to go. People complain that it doesn’t come pre-drilled, the reason is that not all out drives are the same so you have to fit it to the outdrive that you have. Fortunately, I have a machine shop at my house and have a jig setup with various drill bushings, but the method I described above should work for you. Just make sure you’re perfectly centered and secure before you start drilling.

Worked for Volvo Penta SX Gimbal Bearing
Very heavy tool, I was surprised. Pulled my bearing like it was nothing. Putting the new bearing in was a little more difficult as you have to drill a hole in the engine alignment shaft where it will work for your particular outdrive. Not hard, but it does not come pre-drilled as the required depth for each particular gimbal bearing differs by manufacturer and model. Measure your bearing placement before removal and check that it was installed correctly in the first place. The bearing should line up with the grease fitting and the o-rings on the drive shaft should end up riding in the middle of the bearing. once you have your measurement drill the hole, I used a drill press. I suppose you could use it on multiple outdrive models as long as you can drill more holes.

Great value
This kit worked perfectly on my Alpha one mercury outdrive. I saw a lot of people mention that it was a hassle to drill the hole when you better have all this alignment stuff. I threw it in use my regular drill drill guide and then the second hole was lined up. Pulling Gimble be very easy. I did have to adjust it up at an angle because my bearing was sitting in their crooked and it came out the second time I made the adjustment to the angle. I would highly recommend this.
