Ender 3 step by step assembly and calibration

First steps with Ender 3

Ender 3 is the first 3D printer that I had the pleasure of assembling myself. I would like to present the process itself and everything that I had to go through during this assembly. I received the printer straight from China and I was very excited about the possibility of assembling it. I began the obvious by opening the parts review box and reading the instructions. It contained a pictorial description of the part, and a comic book with twelve steps to follow. It is easily solved so even a person with the simplest concept can handle it. Of course, just before starting the syntax, I watched some helpful videos on YouTube.

The set includes a set of keys that is 100% sufficient to assemble the whole. In case you don't have specific tools at home, you don't have to worry. During assembly, I followed the instructions and did not encounter any major problems. Only at one moment I had to disassemble the elements, but it was due to my oversight. However, I quickly noticed the problem and it was easy to fix it. I think that you can calmly through the whole in about 1.5 hours but it took me a little more for other duties.

Calibration

In the next stage, I started calibrating, setting up the printer to start the adventure with printing on Ender-3.

I prepared a piece of paper to set the nozzle at the right height, calibrate the position. However, unfortunately, when I first reached the Home position, I already noticed a significant difference in the Z axis. A piece of paper prepared to set the nozzle was not needed because the height was about 1mm. As the first possibility of error I found the position of the limit switch on the Z axis too high, to tell you the truth someone told me;). I immediately started lowering it. It helped to some extent. The gap on the Z axis was reduced to about 0.5 mm. However, it was still far too much. Fortunately, in Ender 3 there is a simple way to adjust the position of the table on the z axis. In the corners there are knobs for adjusting the height. After a few minutes I was able to set this gap as it seemed to me in the right position.

I loaded the first test model, set the home position, moved the filament to the extruder and could start the adventure with printing. After 5s from the start of printing, I realized that something was wrong. The answer was a simple too big gap. In order to better check the correct positioning of the table, I downloaded a model specially created for this. After several prints of this element and calibration with knobs, the filament adhered well to the table. So I made another attempt to print the target "ship" 🙂 This time everything went well and I had my first model printed on an Ender 3 printer.

Summary

Everything went really easy and pleasant, except that I have some idea about it and I'm not afraid of challenges. For an ordinary John Doe who would need plug and play equipment, I would rather not recommend this printer. I think any hobbyist can handle assembly and calibration. I was also pleasantly surprised by the fact that the set includes more screws and washers than needed to assemble. Often, these small items can get lost so it's worth having them in stock. Everyone certainly assembled the furniture from a set for self-assembly and there is always everything calculated in terms of art. So shopping for a product from china is better and gives us more comfort. I am very happy, currently the printer goes almost all the time. I plan to improve the configuration, which I will write about.

I INVITE YOU TO COMMENT
DISADVANTAGES:
  • Problematic calibration
  • Print quality, there are better printers, such as Prusa
  • No belt tensioners
ADVANTAGES:
  • Price-quality ratio. In the promotion I was able to buy an ender for PLN 550, so it is not a big deal.
  • Pretty easy installation
  • Spare parts
  • Prints well from the first arrow
