When I heard about 3D printing for the first time in high school, I felt very far away from us. To be exact, it was still a long way from home. I took the college entrance examination and went to an ordinary 211 university. I really like the profession, I’m not going to go to college, is this my future? I didn't want to go on like this. So I dropped out of school and applied for a US imperial university. I got enough admissions points and was refused twice. Staying at home and planning on my future. Unintentionally saw this article, why not I also do one, anyway, a bit boring in the home. (No matter how competent or objective I am, this station is not as good as Xline.)
select
As mentioned above, 3D printers have not yet reached the tens of millions of households, and the product line is not mature. DIY is a good choice. Like a four-wheel-drive vehicle that was used as a child, it starts from the basic game and gradually upgrades. As there are few people to play, there is no such thing as peripherals. RCfans ah these more professional forums, but it is a little bit of diving for a few days, plus a few QQ groups, is probably understand the point, Poor operation. That problem came again - buy tb's own accessories or buy business packages. After the entanglement, I chose the latter for the following reasons: First, I am a junior player, need someone to bring, after all, little information on the Internet. The second is that it is very troublesome to choose the accessories. All kinds of screws make me big. The third is to play new toys which do not pay tuition, because buying a package may be about 10% to 20% more expensive. This is my choice.
There are many groups on the Internet that are sold by the owners themselves, allegedly all-metal. The accuracy is still 0.1 at the speed of 150, overcoming the design flaws of kossel, etc. But I can't ignore it. I'm a beginner and need answers to questions. Maybe only micromake this shop can (I said is Kossel structure i3 or other structure of the customer service I do not know), a group of thousands of people, the questions can be promptly answered, I added the other group to a few One hundred people, the discussion is not very enthusiastic, these points are good for novice like me, after all, I am a liberal arts student, although I still love mechanical engineering
Assembly
Thought that the purchase is a package, so everything, in addition to tools - six-party wrench, it is recommended to use extended type, the seller sent SF, postage pay to the hand block price of 1044 election, enough, after all, can save a few A friend with a wide range of precision requirements can choose a track or something (I did not record every step I hope you value understanding)
Tackle Parts List
The kossel structure also known as the delta may be easily grasped because the upper and lower triangular strikes are specifically bought with a vernier caliper or a digital display.
42 stepper motors 4 3 responsible xyz axis 1 responsible for wire feeding
Printing sleeves The red line is the temperature line next to the heating line is transparent (I can not take out the heating line may be due to the heat expansion and contraction screws stuck to stop you not too tight)
Into the seller's own design of injection molded parts can be installed two fans feel like
Installed and back up 
One day's workload is very fast following the instructional video just as there is a limit switch is broken and it's time to rest. The seller directly sent a new one. It seems that the choice was right.
Starting the next day there is a new stopper belt and brushing firmware
Not on the belt so the machine can't stop in midair
The biggest problem encountered during the installation process is the tools. The existing round-headed hexagonal wrenches are not long. Individual screws are not good enough. The risk of slipping is finally good. Another point is that individual parts sellers use prints that are not accurate enough
The height of the monitor is about 5.5cm
But the slot is hard polished for an hour and the print is harder than the hardness of the molded part.
At the end of the finished product drawing height of 370mm, the value of each leveling is not the same ±1mm higher than the design height of 300mm
Top view at home sci-fi
Set off your hijab to the motherboard is one of the seller's own design should also have a logo (upper left corner) The generation of the machine is the most common kind of installation is complex ramps1.4+mks2560+4 4988 is now integrated
Embedded 8825 controller heard better than 4988
debugging
Said that the biggest disadvantage of the delta structure is - always debugging, personally, the limit switch on the print head is very difficult to tune, other tutorials like it, a fool to operate step by step
Use the cure operation to feel that the version provided by this seller has been changed and brushed directly into the mircomake firmware.
At first, I couldn't send a wire to the machine. I couldn't send my hand. The seller also provided a lot of reference opinions. It didn't work. When the seller asked me if it was slippery or slippery? I resolutely returned the two characters and the seller was not convinced that there might be a problem with the throat. I was ready to send a pipe over. I thought that the accessories were all out of nowhere. The miracle was good. At that time, myriads of muddy horses roared past and saw the details. The liquid slipped out of that joy because I finally didn't have to pull it apart, even though there was one less accessory
The next step is the departure of various kinds of curled edges
Alice is beaten into fries
The bottom directly followed the head
Sometimes I don’t know when I’m gone.
For this kind of bottom disengagement, my method was simple and crude, with 502, where there was a point where I bought a new pvp glue stick and hoped to be useful, pva glue was useless, and some people said that using textured paper was cheap. Enough, expensive is a few hundred, after all, my machine is only 1000.
Textured paper 5 6 also shipping Because it is cheaper, so use the yellow scraper to blow out the bubbles Of course, in order to prevent the bottom 502 can also be used
to sum up
Beginners, simple entry machines, DIY, sometimes feel that this is really the future, home to a few guests, you can play some chopsticks or something, you can also play repair parts or mainly to play too few people I had a circle of friends and even the 985 students asked me if I could play metal. I thought it was a joke and I had a few chats. It turned out that he really thought he could fight.
Bicycle speed 80 precision 0.2 20 minutes after playing or will be Alice
Now after playing the Chinese table, it's eleven. Speed ​​30 Accuracy 0.1 Expected to be completed in more than 9 hours
Delta has a simple structure, simple installation, and low cost. It is an excellent choice as an entry-level beginner. However, however, late debugging is too tedious. Try once and for all, once you fail, you must re-emerge.
However, it is worth it for 1000 machines! ! ! !
If you have any questions, welcome to God's advice
