Ah, yes, slicer - different fields use different terminology. Gcodes can define many things, but for 3D printing only few are important. E.g. this code: G1 X0 Y0 F2400 ; move to the X=0 Y=0 position on the bed at a speed of 2400 mm/min So for a new 3D printer, it should be straightforward to translate this Gcode into motor movements. Of course one have to measure the speed, e.g. do the calibration or calculate gear ratios. Web page like this should help a lot: https://www.simplify3d.com/resources/articles/3d-printing-gcode-tutorial/ Maybe there are already some libraries with gcode parsers usable for any general 3d printer? One would have to search.

Hi, unfortunately all I have got to this project is what you can see in the video. It was purely sit and build project with my kid without any planning or making notes. The important thing is to make the structure sturdy, because when the 3Dpen moves and stop it could cause vibrations. Also the wheels I have used are not the best, I belive the Technic, Gear Worm Screw 6L 73763 would make the best solution for movement in all three axes. Maybe next time I would try to move only the table in all three axes, moving the 3Dpen is bad because it is heavy and it is not a lego piece. Also I would open the 3Dpen, install some electric switch outside and controll the extrusion directly. The programming using Boost environment is useful only for kids. If I would do it myself I would use e.g. PyBricks and python scripting. Find some software to convert 3D stl file into gcodes on computer. I cannot recommend one now, but googling results in several softwares. Write pybricks script that implements gcodes into movement of three motors. Load gcode and run. Something like this. Start with minimum. Make the MOC, and try to print simple line in one axis. Improve. Persist! I hold all my fingers for you :)

It has taken me longer than expected, but finally added!

Thanks for the info! Nice rockets. I will add it during next batch (during next two months).

About The idea represents ball-and-stick models of molecules using LEGO bricks. Atoms are made of cubes with technic holes. Bonds are made using soft axles. Many chemical compounds can be easily and quickly created by connecting and disconnecting atoms. To represent valence electrons and bond abilities, the hydrogen atom has one connection point (one technic hole), oxygen has two, etc. Soft axles enable the creation of complex compounds with angled, double, or even triple bonds. Many variations can be made by applying different stickers to the top tiles of atoms. For a set, I have selected 80 atoms and an adequate number of bonds, for a total of 742 LEGO bricks. I have already successfully used this system to show my kids the difference between atoms, molecules, and various compounds. What you can see on the images All molecules in the proposed set. Selection of gases: ammonia, nitrogen molecule, carbon dioxide, oxygen molecule, and hydrogen molecule. Molecules of liquids: sulfuric acid, water, chloroform. Organic compounds: methane, ethane, methanol, ethanol, and benzene. Solid matter: a unit cell of silicon dioxide. Overview of atoms. Two versions are presented: the top one has only simple chemical symbols. The bottom one also shows the proton number and oxidation state. Photo of my real build of molecules. System The idea is the system. One can take only a few bricks and switch top tiles with stickers, or one can build a whole periodic table of elements. However, for most molecules, one needs multiple hydrogens, but helium is not used at all (because it does not create molecules under normal conditions). Changing bonds is very quick, so one can also demonstrate chemical reactions. Two possibilities For myself, I have used simple paper stickers with a chemical symbol, proton number, and oxidation state. The oxidation state was quite easy to explain; kids understood that the number of 'holes' in the element is relevant to the number of 'bonds' the element can make. Sulphur is good to show that oxidation states can differ. The atomic number was perfect for explaining why CO2 falls down to bottom in a standard atmosphere made mostly of lighter nitrogen molecules. The other possibility is to make stickers with only chemical symbols, as shown in most images. Because I had issues uploading images to the Lego ideas, I used it for most images. There is some rule that texts have to be readable, and in the first image, that was the only way to make all texts readable. Why Kids were asking about atoms/molecules/matter etc. So I thought I will find some nice chemistry system using lego and explain the topic. I have found several chemistry Lego systems or ideas, yet all seemed quite complex or too abstract. So I tried to think about something more easy to understand, and easy to build.

Thanks a lot! I have added it, and I follow you at rebrickable, so I will be automatically notified if you make another wonderfull MOC.

It is definitely appropriate! Thanks for noting me about your MOCs, I will add them when I will get some free time. Rebrickable helps a lot, I will just follow you and Rebrickable will send me an email every time you add something. If you want, you can add your mocs to the list by yourself. You can fork the list on the github, add your mocs and make a pull request, however you have to know how git works. I am happy you found the list usefull!

Now I have reached 1000 entries in my list of LEGO rockets, spacecrafts and probes.

Select one of rockets here: https://kaerodot.gitlab.io/lego-rocket-mocs/

I have made an substantial update of my web page. Staistics: 374 MOCs of rockets and spacecrafts 220 MOCs of probes, satellites, spacestaions etc. 102 of other related MOCs

Lego Boost + 3D Pen = Lego 3D printer! Lego Boost provided 3 motors to control 3 axis movements and a 3D pen provided the filament extruder. The precision of the printer was much better than diameter of the filament thanks to the Boost motors with angle positioning. The precision could be substantially improved by building proper carriage movement by a real master builder. I had no additional motor to switch on and off the 3D pen extruder, so the 3D pen is set to continuous mode. Thus only simple objects can be printed. The printer was a learning project for my 8 years old kid. He learned how 3D printer is built, how it works and how it is programmed. He was able to program motor movements to 3D print simple pencil stand. It is quite hard to program every motor movements to print some object. Many free and open source applications are available for conversion of digital 3D objects into G-codes, i.e. motor movement commands. This way someone could make a full feature Lego 3D printer.

Really nice. I was curious about the slot on the side boosters between the booster nose and the booster body. In digital renders the slot looks very big, but as I supposed in real model it is hardly noticeable. You should add some photo into the lego ideas pictures (I wonder for most ideas - is it possible to build or is it some digital fantasy?) I thank you for sharing.

I have noticed your Ariane 5, it looks superb. Studio file is wonderful, thanks! I will add it. Was it built in real life already?

Chha: Thanks! I am happy you liked it, and thanks for the additional info, web is updated. It is my error I put scale 1:110 there. Maverick9154 claims this scale: "Custom LEGO SpaceX Falcon 9 Block 5 with Crew Dragon Instructions ONLY (Saturn V Scale)" However I am building classic Eiffleman's Falcon and I know the 4 stud width is optimal for this scale and the complex structure visible on Maverick's images cannot be Saturn V scale. I have seen it many times - author makes a nice MOC, but only by eye and the scale is quite off. This is the reason I did comparisons of V4, Soyuz and working on others.

Ah, now I understand you. Done.

It is there already: "Download source code or linux, windows binary, read help and how to on the source page:" Maybe grammar is bad? I am sorry I am not native speaker.

I could copy all the informations from the project webpage here, together with detailed how to use with all the images. The issue is, if something changes, I have to modify it on the project webpage and also here. This often leads to outdated information, just take a look at forums of other software, there is a lot of outdated things. But to click on the link and to read that for latest version one can download either source code or binary for windows and linux takes about five seconds. So I understand you want more informations here, but you should also understand that I like to keep data on one place.

done.

Thanks. The most important thing - let me know what you liked and what needs improvement. I have no idea what is workflow of other people.

In the beginning I didn't understood why this particular one shuttle should be better than other 1:220 models. There are several models of shuttle in this scale already done, so what the heck? But later I did some scaling and calculation and understood... The issue is in propagation. For example all the people are building the falcon by eiffleman, because it was first falcon MOC and is most known. However it is inaccurate in some parts and there are better models. But people do not understand why other models are better than the first one (or more evovlved, anyway most falcon MOCs are based on the eiffleman's one). This is the reason why I made the comparison of soyuz model, so I could select between suchshibeinu's and techniek's one. And the same with the 1:220 shuttle. One have to understand that 4 stud bay is too wide for 1:220 scale. But this important information was not shown by Arkaitz nor any comparison made. So I believe there was lack of attention because no one understood why this design is unique in comparison to already developed designs.

applyBLorder What it does: applies Bricklink Order to a Bricklink Wanted list in correct way, works with downloaded files. Output: new Wanted list with increased have count, new Order with decreased ordered count. When to use: If you have one or more orders for multiple Wanted lists. Help: step by step how to is on the project page. Project page: https://gitlab.com/KaeroDot/applyblorder/ Interface: GUI, console Availability: source code, binaries OS: Linux, Windows License: MIT (open source free software) Details: Software applyBLorder applies Bricklink order to a Bricklink wanted list. Generates a new wanted list with increased have count, and a new order with decreased ordered count. Software can handle bricks with any color. A table summary is generated to show the status of the newly generated wanted list showing you which and how many bricks have been assigned from the order. Using this software, you can apply bricklink order onto first wanted list, then the newly created order (with decreased amount of bricks) apply to second wanted list etc. till the order is empty. The first wanted list will take most of the bricks so you should select the one most important for you. The software generates new wanted lists that you can upload to bricklink and continue with ordering of new bricks for your wanted lists. Motivation: Bricklink gives you possibility to have multiple wanted lists. Also you can easily plan buying bricks from multiple wanted lists. Unfortunately, if you try to apply your received order to first wanted list, and than to second wanted list, you will find that you own more bricks than you ordered. Why? Because applying order adds have bricks to the wanted list, but do not remove bricks from the order. Screenshots:

So, in the end, you say that the range of hairstyles is insufficient and you want more of them. That is definitely understandable. But in such case the discussion should remain on this level: TLG, please, make more hairstyles. It does not implicate a race in actual minifigure. "Often" is not "always". Often is relative. The connection you are trying to make is very weak. Is hairstyle indicative of certain ethnic group? I do not think so. My feeling is that every woman changes her hairstyle once per year. More of the hairstyle indicate fashion - 80s were all curly. So, you presented the hypothesis, you should now show the facts to support your hypothesis. After this, you should show facts to support the next part of the connection - that insufficient hair styles on yellow minifigs is offending someone. After you show the evidence, than we will know. But now you talk only about your feelings and present only your subjectivity. (Ad licence sets - this was already discussed on the beginning, why to bring it out again? License sets are not the question. If Londo/Harry is/not black, ask movie maker why.)

I just do not believe my eyes - some people here are purposefully introducing race into the world where race is not existing, based only on hair or clothing style. That is wrong on so many levels... Back to the facts - the example of black girl with white hair and white girl with afro hair is the only fact that was placed here. All other was only about some feeling. Some objective facts please.

It seems to me that you wrote that some hair style belongs to some race. Do you mean this woman with typical "afro" style?: Or maybe this typical representative of blonde hair?:

Thanks, I try to add all MOCs that have instructions added into the files section of the FB page. Unfortunately my time is limited, so I do it only from time to time.
