--Moderators-- please delete this post if its not allowed. Translate was giving me issues on the forum rules page. As may of you know I did a lot of consulting with Creality to help ensure this is a quality product, if you want to buy the new 3DPrintMill and help support my channel at the same time, here is my affiliate link to the Kickstarter.

Naomi and I are working to fix those issues and are trying to make this the best possible printer for first release. I don't know of any printer that is perfect right out of the box, and especially not a new style of printer to mass production. Sorry, I tend to take this project personally as my goal since building the White Knight was to bring Belt printing to the masses. Until a company mass produces this type of printer I don't believe we will see major improvements until enough people have one and start designing improvements.

If it makes you feel any better I've been doing a lot of testing on this already.. Naomi has been working very hard to convince Creality that there is a market for this style printer.. In this case I believe the Kickstarter is more to prove there are enough people interested to justify production.

Here is my latest video. https://youtu.be/F290hgwc_50

To be honest I can't see any advantage to putting the carriage on the under side.. Because the entire X-axis is on a 45 degree tilt no matter which side of the extrusion you mount it to gravity will always be trying to twist it straight up and down.. An advantage to having it on top is that its much easier to service, if it were on the under side you would be trying to mount everything from the bottom and fighting gravity instead of it laying on the top of the carriage.. As for weak-point only time will tell but I think it may actually make for more even distribution to the V-wheels. On a normal printer the two top wheels carry all the weight and then the bottom wheels tend to just skirt the extrusion only rolling when necessary, with it tilted the top wheels are taking the weight and being pulled against while the bottom wheels are being pushed against, so the weight may be spread out better to all 4 V-wheels.. In regards to the size of the carriage I believe most of the Core X/Y assembly is from parts of the Ender 6 so as to keep production costs down. Personally I'm reluctant to have them go with a smaller assembly because usually they reduce the fan size to save space and I have yet to find a quiet 24v fan under 40mm..

That was only one half of the sword (so just one side of the example picture). The mirror of it still needs to be printed and then glued together..

I understand .. It all depends on which direction you need the sheer strength to be. Imagine printing a cylinder 20mm in diameter and 150mm tall on a normal printer and print the same cylinder on a belt printer. Try breaking them in half and see which is stronger .. Because the layers are at an angle you have more surface area on each layer and thus a stronger print .. But this all depends on how you position a model and in which direction you need the strength to be .. For example when I print swords I split the model lengthwise down the blade and ten glue the two halves together. Because the layers are at an angle I get a herringbone look and thus have the layer lines in opposite directions as shown in the picture below .. This creates a very strong print with minimal infill required.

Thanks for welcoming me to the forum. I will try to not get to serious.. I take the subject of the CR-30 very serious because I truly want to see a belt printer make it to mass production so the community can help improve this style of printer.. Until more people have one it will remain a novelty and see very little improvement.. This is the reason I agreed to work with Creality, to ensure the printer they take to market will be quality printer.

My build is not easy and definitely not for beginners, but can be very satisfying to complete. Sadly many of my sources are US based so shipping can be a major downfall for other countries.

Hi, On belt printers the belt is considered the Z-axis so the y-axis is the tilted axis.. Your post did not translate well to english, but form what I can tell your main concerns seem to be resistance of large prints and layer adhesion. From my experience the layer adhesion is just as good as a normal print and in fact by tilting the axis you spread the layers out wider on many prints resulting in stronger prints. As for friction of longer prints I haven't done enough testing to say how big you can go on the CR-30 but it seems every bit as strong as my White Knight (possibly stronger) and I printed an 8ft 4in Thanos blade with it that weights over 2 kilo. I did stack 8 kilos of filament on the belt and it had no problems advancing the belt.. Hope this info helps

Hi, First let me say that I am NAK 3D Designs and the moderators are welcome to verify that the e-mail used to register this account is the same listed in all my videos. I would like to clarify a few incorrect statements in this post. 1. I have only ever received one of these printers from Creality. It was damaged in shipment so this was not Creality's fault it did not originally work. 2. I was not under any obligation to use only Creality's Models, I just chose to use those models.. The cylinder was not their model.. 3. I sliced these models myself and have given all my settings to Creality. 4. I have resolved all current bugs with the printer and see no reason it shouldn't go into production with the modifications I made to it (again all my modifications were shared with Creality). 5. Lastly I hate to be misquotted!!!! I never said "He still prefers to build himself a 2nd White Knight" I've actually built 3 white Knights and though I hope other people build them, they are very tedious and time consuming and I would not prefer to build another... I have many other projects I would rather work on(like the Prusa Style belt printer). This is why I don't sell my printers..... I am hoping most or all of the errors in this post are merely due to a translation error and not deliberate. Respectfully Karl Brown NAK 3D Desgns
