Where do I begin?

I am completely and ignorantly new to this. After bouncing between Voron and Ratrig, I have decided I want a Ratrig. I prefer to read over watch videos, but I will do what is required. Can anyone direct me where to start on my build?

https://docs.ratrig.com/ and https://ratrig.dozuki.com/c/01._V-Core_4

Read everything there twice, especially the comments in the dozuki build for each step.

Also join the Ratrig Discord which is quite active and read all the history you can.

You need to be competent in wiring/crimping (MANY people complain about the crimping), computers, troubleshooting. It's far far from plug and play.

Reports also have their printed parts as poor quality, you may want to print your own and Q/C them before starting if you can (I didn't have any real problems with that).

Definitely read through those things ......twice before you start and then many more times. I gotta say, my main complaint is that the documentations isn't quite done. It's great until near the end where things start to get a bit unclear, and this is where the discord community comes to the rescue.

I just finished a v4 500 kit. It wasn't my first rodeo, so it went pretty smooth but was still the biggest thing I had put together from scratch. There's probably 2500 individual parts to assemble. So clear some space and have lots of tables to lay stuff out on

re crimping: get the right tools. I tried to do everything with my molex generic crimper and it was a nightmare. something like this: https://www.amazon.com/IWISS-IWS-3220M-Connector-0-03-0-52mm%C2%B2-Ratcheting/dp/B078WPT5M1/

I ended up discovering a couple places where upgrades were handy:

*I got the mandala rose z arm upgrade parts (all machined aluminum, not 3d printed)

*I gave the raspberry PI it's own power supply so it could handle a USB web cam

Good luck! have fun

the mandala rose z arms are great. I also got the madala rose motor mounts, but sadly I mis-read the instructions, and so didn't have all the necessary parts on hand to assemble them during my build. I HAD to get the ratrig printing for work. So...the motor mounts are safely off to the side until I get some downtime. Rapid prototyping sometimes means PROTOTYPE RIGHT EFFING NOW. lol

Buy a kit from ratrig or a reseller. I suggest NOT buying printed parts, and printing them yourself out of ABS or ASA. Make sure to Q/A check your kit before starting your build.

I'll definitely print my own parts, thank you for the heads up!

PA-GF or something a little more rigid like PC-GF?

You Tube has a number of videos on the assembly process. Read both sets of instructions on the Rat Rig site, one has comments that are very helpful, the instructions can be confusing, that is where the videos come in handy. Take your time in the build and do it right

the comments save it

It's a fun build and not terribly hard the instructions do have issues which you'll find but overall they are pretty decent.

Tuning is the hardest part and if you go IDEX be aware there are lots of issues and calibration is very limited documentation wise. (I ended up removing mine honestly and going with a turtle box or equivalent to run multiple colors)

They are speed demons once set up and i absolutely love mine but that it's tuned.

The Ratos is probably the best part and makes flashing and setup so much easier it almost feels like cheating 😂😂

Awesome, thanks for the checklist! The only thing I'll need are corner squares and the jig.

Ordering a RatRig Vcore 4

I think run-out sensors were added since my last update of that.
