Quotedlc60 You haven't said what you are going to do with your creation. To make design decisions you have to start by defining what the end result needs to do. DLC You are right! I am a beginner in robotics and want to build a robotic arm without a specific application in mind. The main goal is to learn by building it and then play by programming it to do fun stuff like playing chess, pickingby kuan - Robots!
Well, respect to Makerbase -- they managed to build a $20 closed loop stepper motor. They didn't steal anything, their product is open source and is based on another open source product (and they acknowledged the original creator).by kuan - Stepper Motors, Servo Motors, DC Motors
Why are you saying that they are dishonest and how are they stilling other peoples work? On their github repo they write: QuoteMakerbase Based on the open project of nano_stepper by Misfittech:.

So there are two versions of Servo42, A and B. Here is the comparison of the two: Is the version B closed source as it says? Does it have usb? And what is the role of the serial port? From this comparison (if it's correct) it seems that I will prefer the A.by kuan - Robots!
Hello! I am planning to build a robotic arm (5 or 6 dof) with stepper motors (probably NEMA 17) which I want to be closed loop. The budget is up to 30$ per closed loop stepper motor (motor + driver + encoder). In addition I will need a motherboard to control them. What option are there? As you understand, at this budget I am looking for Chinese products and not the more expensive options like (oby kuan - Robots!
Ok, so I got an answer directly from Makerbase. It turns out that both motors use Allegro's A1333LLETR-T magnetic encoder. In fact, previously they were using AD5047D but because the supply was very unstable they changed it to A1333LLETR-T.by kuan - Stepper Motors, Servo Motors, DC Motors
Hello! I am thinking to buy the MKS Servo42A however I couldn't find any information about the magnetic encoder they use. Does it have Allegro's A1333LLETR-T encoder as in MKS Servo42B or the better AS5047D?by kuan - Stepper Motors, Servo Motors, DC Motors
