Hi, I was using the bootycall jones rail but I really disliked the loss of build volume. I have your files bought and printed but I'm wondering, would you know, if the bootycall mounts for the motors would work with your design or would I have to put back in the stock motors? Thanks.

Will I notice much difference if I don't go for C class Z1 preloading type of MGN rails?
Price difference is quite a lot, between those and "normal" ones. Thanks

Apologies, I’m cannot comment. The stock design has a level of preload in it hence sticking with a preloaded linear rail. I would assume that you may end up with some resonance and VFA issues without a preloaded rail.

Any chance of modify to work with MGN12 rail?

Mils24
Mils24

No, it’s not possible to maintain the stock print area with a MGN12H rail hence why I chose to use the MGN9H.
There are other options available online that utilise a MGN12H rail but come at the cost of slight loss in build volume and modifications to the start print code.

Will your design work with the K1 Max CFS upgrade? Does the carriage and hotend go to the back wall as for as the original?

Mils24
Mils24

Yes, my design has the EXACT same build volume and movement range as the stock machine. Therefore it’s fully compatible with the CFS upgrade and will need no modification to the new CFS firmware.

Hi! Is there a mount that's compatible with this toolhead for a BTTEddy?

Mils24
Mils24

I’m afraid currently there is not. I have been making mounts as per customer requests but my Mac is no long ed by Fusion360 as of the 31st March.
I will be buying a new Mac v.soon and will be able to make one then provided I can fine details and dims of the BTTEddie somewhere to design around.

If you want to do the mod in prep for it use the Cartographer X carriage as the pick up points will be the same. It will just be the BTTEddie mount that will change.

Got it! Thanks
Also just want to 100% check that there are no changes to the stepper motor mounts?

Nope, no change to the stepper mounts :)

Just an update! Printed out of PA CF, carbon tube cut and inserts inserted all installed in to the printer now and works a charm! The x-axis is now super smooth and I no longer have some weird noise when the print head moves to certain parts of the build plate. Was surprising how much the original x-axis was binding when the 2 rods aren't perfectly aligned.

Build/BOM not difficult. Highly recommend!

I checked last night and my CAD package seems to still be working on my Mac therefore I should be able to get a BTT Eddie mount made in the coming days.
Watch this space….

Do you still need a BTT Eddie mount or have you already got a solution?

Hello. Could you provide an estimate for what the BOM costs to purchase please? Thanks.

Mils24
Mils24

This is a hard one to answer as not everyone needs everything.
Plus you can make more expensive or cheaper depending on what linear rail you choose to use.

Using all links provided in guide your looking around £60-65 GBP / 71-77 EUR / 77-84 USD

Mils24

Also depending what filament you choose to print parts in will also effect total BOM cost.

Pure ABS is a LOT cheaper than ABS-CF or ASA-CF for example

onlyonefbson
onlyonefbson

That's fair enough, thanks. Just to nail it down a bit before I proceed then, could you advise what the linear rail options would cost from your recommended source, for a k1c length, for example?
Thanks again!

Mils24
Mils24

For K1/K1C/K1SE you need a 320mm linear rail.

HIWIN (imo the best option) is 43 GBP / 51 EUR / 55 USD

Thanks for the info. I purchased your files yesterday. I'm looking into ordering components etc - but firstly, I've got to say there's an impressive amount of effort you've put into preparing your files and regardless of how well things go, and I've no doubt it will go well, I can say that my purchase is excellent value. Thanks!

Thank you so much for the kind . Good luck with your build! I don’t think you will be disappointed!

Hi! If I purchase a older version heatsink as suggested for my K1C that has the curved and uned one, will I still be able to use the same nozzle and overall hotend parts that came stock and I already have? Thank you for your effort, great design, I'm willing to purchase it if I can.

PS: what is the recommended wall thickness for the carbon tube also, please (i'm trying to see if it will be possible to source the necessary components on my country) Tks!

Mils24
Mils24

Hi Krahembuhl, yes, if you buy the replacement heatsink as per the guide you can keep the rest of your hotend components. Just make sure you get a heatsink as shown in the photos that suits the unicorn hotend.

As for wall thickness of the carbon tube, 1mm minimum is suitable.

The guide uses a 10x10x8mm (outside x outside x inside)

TY, bought it today, will start buying the hardware. If I encounter any bumps, can I you somehow? Thank you!

Hi, thank you for the .
Just send me a message on here and I’ll pick it up quick.
Good luck with the build.

Could be F623ZZ instead of the Toothed Pulleys 20T?

Yes, if you wish.

Is the inside of the Carbon tube you use a round or Square thought id better double check before ordering one to get parts ready to go? Amazing looking work can't wait to get the files printing just gotta pick a colour Cheers

Mils24
Mils24

It’s an 10x10x8mm square carbon tube

(10mm square with 1mm wall thickness)

Good luck with the build 👍🏻
