RailCore II corexy

kraegar

I’m pleased to be able to make a major announcement!

KITS ARE ON THE WAY!

We’re partnering up with Project R3d to make RailCore II kits a thing.

What this means for the Open Source RailCore:
The RailCore will remain Open Source. The BOM, Build Guide, and fusion models will remain published as they are, and will be updated as we make changes. Nothing changes at all there, all future adding and improvements will be compatible with existing RailCores. The option of self-source building will remain available.

So what are the kits?
To the largest extent possible Project R3d intends to offer a “True to the BOM” 300ZL kit - the final components aren’t 100% done, and some minor changes will be necessary, but overall it will be the same RailCore you can get today, just with “one click shopping”.

What to expect in the kit:
Duet & Duex5 electronics will be included.
A wiring harness to simplify wiring to the Y carriage. Cables cut to length and pre-crimped.
Aluminum parts including the Bed, Stepper Mounts, Idler Plates, and X-carriages. (Still sourced from 713maker & Mandala whenever possible)
Various options for hotnends including E3dv6, Mosquito, or no hotend. (so you can “bring your own”)
Options for an extruder or a Bondtech BMG, or no extruder (so you can “bring your own”)
The bulk of the parts will look much as they do today - right off the BOM, and the printed parts done in Atomic filament (CF PETG for the structural parts).
Pricing is expected to fall between $1300 - $1700, and has not been finalized.
The timeframe for kits has not been finalized, but we're hoping within the next 1 - 2 months for the initial batch.
Project R3d will provide hardware support, J. Steve White & myself will continue to provide build support & continue with R&D to keep making the RailCore better. 713Maker & Mandala Roseworks will continue to be partners, without them we wouldn't be as far as we are.

Next steps are putting together a forum (we’ll move off of SeeMeCNC’s) to offer support & info (we’ll keep the Facebook group alive too) and work on touching up the documentation. The initial batch of 10 kits will be coming in the next few weeks, and will be used to test out the process, catch any issues, etc.

We’re looking for feedback from the community - what do you want in a kit? What questions do you have?

We’re looking forward to the partnership with Project R3d, and to see the RailCore II be made accessible to a wider audience!

@kraegar great work! I was impressed with both the Railcore and Project-Red's machines I saw at MRRF and I know you have continued to improve them!

Can't wait to see these kits available. I have looked over Project R3d printers and was liked the build quality so I expect the kits will be excellent. Good people too.

kraegar

Thanks @T3P3Tony! Looking forward to the "easier shopping" aspect of the kit for sure.

@nhof Yeah - their printers were really nice. We're already trading design ideas back and forth, too. Initially the kits will mostly be a 'parts bundle' of the BOM parts, but over time I expect it to offer some real advantages to make it easier to build (wiring harness, pre-tapped extrusions, labeled parts, etc)

The Kit Pre-orders for the first batch of are live! Reserve your spot in line! https://www.projectr3d.com/products/railcore-ii-300zl-full-kit-pre-order

The first run will require you to tap your extrusion, we will be building the jigs to utilize our power taps in the future. As the RailCore Team continues to improve the printers we will work with the to provide what we can in the kits. Let us know what you want to see and if you have any questions let us know!

What's the status of the kits? Has the first batch shipped yet?

I'm hoping by the 2nd or 3rd batch to have the cash available to purchase one. After self-sourcing my delta, and the considerable extra time and cash outlay that's been, I'm ready for another kit.

kraegar

First kit shipped and the rest will be going out soon!

PlasticMetal

Thanks for the update, kraegar. Will the 2nd batch be in mid- to late November?

Project R3d handles all the logistics with the kits, so I'm not sure of the answer on that. You can email them and I'm sure they'll give you a timeframe, though!

@kraegar The RailCore II 300ZL kit looks amazing and I am definitely saving up for this to be one of my next 3D printer purchase. I also wanted to say that the "Halo" prototype looks good and I wanted to suggest a idea for it. You should expand the Halo exterior profile to add slots for a removable top enclosure made of acrylic or PC. Thought it would be a good addition to the optional upgrades for the kit. I only suggested the profile expansion because from the photo I do not believe the moving components would have proper clearance with the current slots in the design.

PlasticMetal

Where can I see this "Halo" prototype?

kraegar

@Jared_Braden we have designs for a top enclosure in testing, and some changes coming. it will be both "halo" and "standard" compatible.

@PlasticMetal Here's the YouTube video where I installed and discussed the halo on my 250. I've turned the model for the 300zl halo over to 713maker for milling: https://www.youtube.com/watch?v=9udGI_555m0

3D Printing Nerd did a quick review of the Rail Core II 300ZL. https://www.youtube.com/watch?v=D7wYGaTCIW8

Such a slick kit.

@kraegar Hi,
Thanks for all the hard work on the railcore. I have just ordered the parts to build this
was wondering if it is possible to get the model for the halo 300zl so i can get it milled locally? is way to expensive to get it sent to australia.

kraegar

The halo files will be released once they've been tested on a 300zl, and confirmed to work. Then I'll clean up a lot of cruft from the design, and publish it. Probably within a week or so of testing, depending on my work schedule.

Wyvern

Sweet, Linear rails on the Z axis, exactly what I was thinking about, lets see those feeble lead screws try to wobble that bed ha!

kraegar

@wyvern Especially if you put the aluminum yokes on.

Killerm1

@kraegar great! Thanks again

What's up with the RailCore forum and wiki? The security certificates expired over 2 weeks ago on the forum, and 10 days ago on the wiki. Prior to that, the forum had been getting bombed by Russian spam, and it didn't seem any admins were paying attention.

I'm trying my best to not get sucked into the cesspool that is Facebook, but it seems that's the only place still alive.

kraegar

Sorry, yeah. Our domain admin has been awol a bit now. We're migrating content from the wiki over to github ( https://railcore.github.io/ ). Not sure what we'll do with the forum long term yet, it was pretty under utilized.

In the meantime, #RailCore on IRC, or our discord channel at https://discord.gg/6kPKDRZ are good ways to communicate.
