Hi Karl
Has this device model ever had buyers?
If so, who bought it and who needs it?

Thank you in advance for your answer
SeyedAli

Hi I'm very interested in building my own white knight and I am needing a parts list so I can start buying the plethora of parts required.

Thank the Lord I was blessed to get in on the belt group buy and already have the hardest part to get. All I require now is the rest. I trued to find a parts list with no success. If it's not too much trouble for you could you also include where you were able to source each piece I would be so grateful!!

Thanks for creating this awesome 3D printer!!! God Bless!

Hi,

Tj says he's done leading the group buys. I missed the last one and am willing to lead a group purchase to get a pair myself. If you're interested in joining in, comment on this issue and we can group up. I will keep this issue updated as we get enough people.

Quoting this info from the other group buy as the pricing/shipping arrangements will likely be the same:

Okay pricing for the white knight belt:

1 Belt: $450
2 Belts: $400 each
3 Belts: $355 each
4 Belts: $325 each

There is also the price of shipping which is from them to my address and then from my address out to you.

Hey Karl!

I'm curious as to where you sourced your thermal isolation washers for the hot and cold plates. I apologize if you've covered this elsewhere, but I couldn't find them in the BOM.

Thanks man!

Hi. i have trubble downloading some stl files. something that can be fixed?

these are the files that cant be downloaded:

2-Roller_Insert.stl

2-Side_Support_Bottom_Brace.stl

3-Pulley_Bearing_Mount_V2.stl

1-Peeler.stl

Hello everyone,

im building on my own version of a Beltprinter with 4 Nozzels.

But the problem is that neither CrealityBelt or CuraBlackbelt have multinozzel
for Beltprinter support. Dont get me wrong its work perfectly fine with "normal"
Printers but not for Beltprinters.

If u cant imagine what i mean i added my Fusion Hotend build.
Belthotend.zip

Hey gang,

I'm trying to squeeze a solid state relay into the Squire CBA tray to no avail, so I figured I'd have a go at modifying the slide tray design to accommodate one. However, when I pull up the tray parts 1 and 2 in Fusion 360, they seem to start with a pretty finished design that's then tweaked and cut in half. Is there a version available that I can use to fundamentally tweak to make the whole assembly longer?

Or am I just doing it wrong? I'm certainly a novice at modeling so feel free to point me in the right direction :)

Hi. i downloaded the firmware some months ago but have not tried the firmware befoure now. the program crashed when choosing nozle so i deleted the program. now i cant find blackbetl 3.6.0 and the update because they only hav the new 3.6.2 program. what shoud i do to make this work?

• Thomas

Hi Karl,

I am busy to update the C-beam Fusion 360 files using your dimension from the White Knight Assembly Part 2 video.

• 5.5mm holes

  • 198mm from front
  • 342mm from front
  • 763mm from front
  • holes are 10mm from the center or 30mm + 50mm from bottom
    They are bit different from the STL but don't see an issue here.

• C-beam_1 electronics cutout

  • 210mm from front
  • 335mm from front
  • and 23mm from center or 17mm + 63mm from bottom

• C-beam_2 electronics (switch enclosure) cutout

  • 240mm from front
  • 300mm from front
  • and 18mm from center or 22mm + 58mm from bottom

I have few issues/questions:
The holes on C-beam_1 are 12mm and 7mm away from the cutout, should these have same distance?

Maybe i am wrong but that looks wired to me as the "CBA_slider_tray (123mm x 35mm) " and "slide tray end cover" are sliding in the 570mm 2040 extrusions while having the 125mm x 36mm cutout not in the middle of the 4 holes.
Should it be centered as it is on the C-beam_2?
Changing the cutout to 207.5mm and 332.5mm awould center it between the holes.

On the other hand the C-beam_2 it looks good, as the Switch cutout (60mm x 36 mm) is 42mm from the holes on both sides /centered.

Hi Karl
Doesn't the belt slip on the rollers?
and
Why is the plate under the belt an aluminum plate?

Could we use other types of cheaper conveyor belting like this pvc one here: https://www.dhgate.com/product/perimeter-900x200x1mm-customized-pvc-white/533630499.html?f=bm%7cGMC%7cpla%7c1471809117%7c59782623991%7c533630499%7cpla-748316044550%7c011014006004%7cUS%7ctimcent%7cc%7c2%7c&utm_source=pla&utm_medium=GMC&utm_campaign=timcent&utm_term=533630499&gclid=Cj0KCQjwhIP6BRCMARIsALu9LfmObRYl7HSt0gs-WOATYmT2bSxAk4h9YCzij1UgB4lSGxgSPNNw1BwaApBQEALw_wcB

And maybe put custom long buildtak sheeting on the conveyor belting.

Almost like this guy did: https://www.youtube.com/watch?v=aF0wnY1v0Pk

Just an idea, would make this project much more affordable

Cheers,
Aidan Villacampa

the current BOM is awkward to read since it needs a spreadsheet application just to open. I suggest consolidating the BOM and the order pdf's into a single readme.md that contains all the info of all the original spreadsheet and pdf's.

Hi from Chile, i'm currently starting to use the cr30... I've seen that people reccomend yours profiles for the cr30 but haven't been able to find it, Do you know where can i download this profiles ?

How should the files in the Fusion 360 folder be organized? For example, I found the STEP file for the 40mm blower fans on grabcad, But I don't know where to place them. I added the Bulk hardware from McMaster car to its own folder, should we have a folder for electronics, bulk parts, and 3D printed parts so that we can find what we are looking for easier? what would that structure be? LMK your thoughts.

Just an idee:
Wouldn't it make sense if people claim ONE STL file at the time they are converting to STEP / Fusion 360? Or making a conversion status list:

This way we could prevent double conversions and hopefully get it done faster.

What do you think?

Hi Guys, I had to make a change to the Build Plates see (v3) basically I offset the center 400mm area to the right. By doing this the drip tray will now be too small to fill the void between the main 4080 extrusion and the buildpate.. I'm currently busy getting a mockup kit pieced together for PS to use for sourcing kit components and creating assembly instructions. If anyone want to take a crack at stretching it out 5mm more, I'll test fitment one I receive the newly cut plates.. If you look at it from the top it should just be a matter of carrying the diagonal edges out 5mm further.. If there are any question let me know..

Do you have dimensions of the fully assembled printer (not the print area) I'd like to know if this would fit in my current workshop

Hi Karl, after seeing your 430mm high print video I was wondering why the heated plate is just 230mm long (z-axis), as a print that high would need ~335mm heated plate until it is finished.

Example:
A 430mm tall, 400mm wide and 50mm long print

• The bottom of the print would be on the heated plate up to ~330mm height
• The following 50mm height to print it would slowly move to the cold plate
• The last 50mm height to print it would be just on the cold plate

That might work for PLA but other materials may not stick anymore/loose adhesion with dropping bed temperatures and prints above 330mm may fail.

Did you choose for 230x400 because of available heating elements?

Thinking:
Terms:

• I want that the print stays on the heated plate until it is finished
• Heated plate must be 230mm x 400mm

Conclusion:

• max. print height at 45° would be ~330mm
• Y-axis travel distance of the x-axis gantry would be ~350mm
• Y-axis MGN12 Rails need to be at least ~350mm+2x 45mm(MGN12 block) =min 440mm

So I would need 2x 500mm MGN12 rails instead of 1000mm one which need to be cutted for the existing design (saving on these $50)

The travel distance of x gantry on the 500mm MGN12 y-axis rails should be around ~410 mm.
This would mean we have 60mm space for the tools of a tool changer system

Hello,

I was wondering if anybody would be interested in possibly a frame kit from LDO Motors that is already cut down to spec for the white knight and with all the holes drilled in all the extrusions, holes cut, ends tapped, etc. You will probably still need to drill and tap the holes for the linear rails as that is different for everybody unless I could manage to get LDO to do that but I doubt they'd be willing to.

There is a very high likelihood that I would be able to get a motor kit from LDO also with everything that we would need. They wouldn't need to have connectors on them we could do just plain wires on the end all prepped for soldering later on with the wiring.

I could also probably get the linear rails cut down to size from them with the blocks and everything and have that all in one kit. I want to see if anybody would be interested in any of these kits. Again the same idea with the fees and everything.

LDO -> Me
Me -> You
CC processing fee from Paypal

I would like to know if anybody would be interested in this. If you are please add your name to the spreadsheet and select from the dropdown what you would be looking for. I'm going to send an email to Jason over at LDO and see if he would be willing to do anything like this.

hi!

Hello.

is it a possible that you can post a video where you install all the data on the duet and how to make all of the systems work. im struggling with this...

• Thomas

Hey Karl,

Curious as to who you used to machine your hot/cold plates. Been having trouble getting someone to do it without technical drawings and that's well beyond my CAD expertise.

Any recommendations you can offer are greatly appreciated. Thanks man!

Hi Karl
What's the plastic material you used over the steel belt?
Is it a Neoprene Rubber Sheet?
Can you help me about it?

There are a few parts in the BOM I have a Problem with

• Duet Wifi = There is only the new version "Duet2Wifi" available, but i red thats not a problem. is that right ?

• Mosquito Mount = is not available. but i saw in the CAD that this would be a "Groove Mount Bowden Adapter"
  https://www.3djake.de/e3d/groove-mount-bowden-adapter ?

-Slice Thermistor = there isn´t stated which one i need. when its the "SLICE ENGINEERING HIGH TEMP THERMISTOR" is it the availible "RTD PT 1000" for 50$ or would the 300°C version OK ? but this ins´t available either. is there an alternative ?
https://www.printedsolid.com/products/slice-engineering-high-temp-thermistor-1

-Silce 50W heater = is it the "SLICE ENGINEERING 50W HEATER" in 12 V or 24 V version ?
https://www.printedsolid.com/collections/all/products/slice-engineering-50w-heater?variant=12533493989461

-LDO .9 Stepper = there is no such stepper on the website. I only found this : https://www.ebay.de/itm/333367708304
I dont know much about electronics. chose this project to learn something about it, but dont want to order the wrong parts

-Nema 17 5.1 geared stepper = on the stated website not found. found only 5:1 geared here https://www.ebay.de/itm/392172201987
is that right ? is there an alternative

Thanks in advance
Yours sincerely Daniel

Hello,

I was looking through the BOM of the White Knight, and tried to find the silicone heater used with the info that's present and couldn't find anything, would it be possible that rather than a ebay number, you could post the dimensions and voltage/wattage of the heater itself?

Thanks so much.

Hi there,
I really like your design of this printer! My name is Ludo, I am currently doing a graduation project at my uni in the Netherlands, in which I am trying to design a 3D printer for production of medical devices in Africa. One of the main features I want to integrate in this design is a conveyor belt system, very similar to your design, to enable continuous printing. I am about to start building a first prototype, and had some questions that I was hoping you could help me with.

Do you experience any warping issues? I can imagine that cooling of the bottom layers will cause shrinkage, and could curl op the belt. If not, how did you solve this issue? What type of belt are you using? And where did you purchase this? I am having a hard time finding the right materials. Currently I am looking into a belt made from stainless steel (0.1mm thickness).

You can also contact me by email: [email protected]. Or we could have a quick skype call.

I would be very grateful for any help you can offer!

Here's a picture of a very quick sketch of my current idea. I'll be upgrading a Prusa MK3.

Best regards,
Ludo

Hello
Is it possible to replace an Arduino board with a Duet 2?

Hello Everybody,

My name is TJ and I have been the person who has pretty much coordinated (to my knowledge) the group buys for the belts on the printer. I'm running another one again as I have more free time than I would like to admit, so here we go. This time I am being up-front with you about everything that goes into a belt purchase for the group buy. I am copying and pasting everything that I wrote yesterday on the Infinity Printer's Forum for sake of not repeating myself and making sure to get the entire information there.

Message:
I wanted to thank everybody once again for participating in our group buys. I wanted to put this out there because I’m willing to do it again, with the current situation I have a large amount of free time on my hands and would be willing to set up another buy if anybody is interested.

I’m going to be completely transparent about everything just so you as a consumer know what your options are and how everything works for this.

So when you ask to participate in the group buy you add your name to the spreadsheet, that spreadsheet stays available usually for about a month or so and then once we get close to me closing it I reach out to everybody to make sure they are still in for the price of the belt.

Once that is confirmed I reach out to Scott over at Belt technologies and he helps me setup the invoice and I get the price per belt.

The price that I relay to you includes all of this in the amount:

Price for the belt given to me by belt technologies
2% CC fee charged by belt technologies
Shipping fee from belt technologies to me
Shipping materials fee for shipping the belts to you (20x20x20 box)
Shipping Fee for the belt from me to you
CC processing fee charged by the company I use for invoicing (2.9% + 0.30 flat fee)

That’s a lot and in my opinion, the way this works out the best for you is if you are local to me and you come and pick up the belt, that way there are no shipping materials necessary and gas is usually cheaper and shipping providers.

I’m in Essex county in Northern NJ. Again completely transparent also, I’m an 18-year-old senior in High School, but you can trust me as I have done similar things to this numerous times.

If you have any questions about this, or interested in me setting up another group buy, you can reply to me down below. You can shoot me an email at [email protected] (I usually reply pretty quickly and if not within 24 hours), or send me a message through the issues section on the Github that is located there too.

To note also, I am building my squire in a series of live-streams on my YouTube channel: https://www.youtube.com/c/ntw3d. If you ever want to talk there I usually do a stream once every other week or so, we can talk about belts there.

Again I do these belt purchases to help you guys out a little bit, I usually add about $20 onto each belt purchase because coordinating the purchase of these takes a lot of work, so I need to get a little something out of all of this. Unlike the first one I'm not actually participating in the buy.

If you are interested in joining the group buy please add your details to the google sheet and I will reach out to you later on down the road when I will begin to collect payments to make sure you are still willing to get this belt.

Stay safe and happy building

-TJ

I'm not a lawyer, but the main reason I didn't experiment with infinite-volume/belt-based 3D printers before was Stratasys patents US8282380 & US8287794.

You have probably encountered these before, but is there a consensus, or hope, that these patents don't cover a printer with a slanted Z axis like this one?

This may be a potential barrier to commercialization (and I wouldn't put it past Stratasys's lawyers to go after individuals, either).

When you have time, would you please update the main Readme file to include a rundown of the various specs to include (but not limited to):

Layer Height Range (min to max)
Build Volume
Min and Max Travel Speeds
Full Step Positional Accuracy (microns in XY & Z)
Microstep Positional Accuracy (If you provide both of these specs, you'll be more up front than any other 3D Printer I've seen so far. They all want to go by their microstep accuracy as it is more "impressive", but if you can also include your full step positional accuracy, you'll help people achieve better prints!)
Filament Size
Max Bed Temperature
Max Hot End Temperature
Overall Weight
Overall Dimensions
Anything else you can think of that would be neat to see at a glance?

I've gotten the answers to many of these things from various places, but it would be nice to have them all in one spot (and to verify what I've heard in videos and pulled from other places is correct.)

Hi, This is probably the wrong place to ask but I saw somewhere about kits being made for this. Not only am I keen to acquire a kit with all the non-3D printed I would be extremely interested in helping out either sorting or helping to distribute these. I live in the UK and I know that shipping from the US is just eye-watering expensive to elsewhere in the world.

Paul

I want to run it on the brand new BTT 32 bit boards. That would be awesome. If this is open source, and you give me the details on all steps taken to make the DUET files such as setting changes, I would happily compile marlin files for the world to use.

I would like to order the belt from Belt Technology UK, could you give me the characteristics that the material must have? Thank you
