Arduino mega 3d printer pinout4/16/2024 ![]() I adjusted my code to run the motor a bit slower. Hopefully its something minor in the code that I am getting wrong! I have been working in matlab lately so jumping back into C++ has had a few hiccups! Other than the code, I think it may be the stepper being put in sleep mode unintentionally, and I need to figure out how to adjust that in code.Īnyways thanks for any help in advanced looking forward to hearing from you guys. Maybe there is a good library for doing this, but I really like the tutorial linked above as it gives a lot of options when it comes to programming. ![]() I will say that I did pull the jumpers out to see I could at least get it moving in full step mode. Maybe the stepper is sleeping due to other pins I'm not aware of not being initialized correctly? Maybe M0, M1, M2, are initialized incorrectly(I doubt that though, I am guessing they are hard wired to 5v). I swapped out the driver just to be sure, and doubled checked that I didn't have the pins initialized backwards. I also made sure the loop was running correctly by dropping in some Serial.print() functions in there. I checked the stepper driver for a voltage on the "pot" and found a voltage of about 0.45v, which is correct that means it is getting power. ![]() I found A0 and A1 pins to be responsible for the "dir" and "step" and initialized them in code as he did.Īfter getting it all set up, I couldn't get the motor to turn at all. I used a volt meter to determine what pins I needed to initialize. I found this useful tutorial right here -> Anyways I figured I could easily use the ramps board to interface with the steppers as needed. I'm just proving some concepts first and seeing what I could potential do. I have been wanting to build a star tracker/pointer thing for a while. I'm excited to be part of forum as it looks like I will be doing more, and more electronic oriented projects in the future!Īnyways I have an extra arduino mega, and ramps board with working stepper motors from a previous 3d printer.
