How to Calibrate Stepper Motor Drivers In this post we are going to explain how to calibrate the stepper motors drivers for our 3D printer. We need: Power supply with power cableArduino Mega + Ramps 1.41x Stepper Motor Small ceramic screwdriverStepper motor drivers to calibrate
We can do it in two different ways: measuring the voltage or current intensity. We recommend doing it with current intensity, as it is safer and simpler. We are going to calibrate the current intensity we want for each axis and for the extruder. The needed current intensity depends on each printer. In the case of ou...
Many of you have asked us for a Dual P3steel kit, and today is the day: we have designed this kit for you. It is based on our popular P3steel, we have taken care of every detail in order to offer an easy assembled kit and easey to use, as well as very realiable. Among its features we point out: It is assembled with the same frame we use for our single extruder P3steel, so for all of you who like to modify 3D printers and make tests, you can find here an interesting project. We have designed the extruder from scratch, placing it in a very discreet and accessible position, that minimizes the ...
It is usual that new 3D printing users feel overwhelmed by the quantity of information we can find on Internet. There is a lot of high quality information, but it is also quite easy to get lost and feel confused. On the other hand, advanced users may discover interesting things in these links. We will try to keep updated these links. And also, we accept suggestions and recommendations. Reference Websites http://www.reprap.org/ - It is the main website of the reprap project, in it you can find everything, from information about the beginnings of the reprap projects to very updated tutorials....
The functioning and the connections of a stepper motor are simple concepts deeply.There are different types of stepper motors. In 3D printing the most used are "Hybrid Stepper Motor", with two phases and 4 connections; which combines the features of "Variable Reluctance Motor" and "Permanent Magnetizing Motor"In this video we can see the types os stepper motors, as so as its functioning: As we have seen, the stepper motor has two phases with two connections per phase: four connections in total. We can see them at the diagram: Which position must have each the connection? We must connect ac...
How to print PLA?
PLA filament is undoubtedly the easiest and the most popular filament. Thus, nowadays it is more than the 80% of the total of manufactured filaments for 3D printers.PLA (polylactic acid) is produced from lactic acid, which is obtained from corn starch, cassava, or sugar cane.
Among its advantages we can point out:It melts at low temperatures.It has a low thermal contraction, so it produces few warping.It adheres very well to itself (excellent layer union).It releases few smell during the printing.It is biodegradable.It allows to print very accurate parts or models thanks ...
Are you looking for free STL models to download and print them with your 3D printer? One of the characteristics of this technology is that everything is shared, and largely for free. Here you have a list of the main websites where you can find high quality models ready to be 3D printed at the moment. Thingiverse Maybe one of the most popuñar websites to download models. It has a great community of users that offers plenty of designs of different categories. It is perhaps the best starting point.
