Generally Sparkfun has excellent tutorials (and often Fritzing parts) for their stuff.Fritzing nema 17 WebArduino Code + Fritzing for: Uno, A4988, Stepper Nema 17, 2 buttons Button 1 44,25 turns, Button 2 0,75 turns. If you post the Fritzing sketch of your hook up I expect one of us would point out any problems we see.Įdit: reading further down the data on the board there is also a current limiting pot, if that is set to less current than your motor needs to operate that would also cause no operation very likely.Įdit2: I got this information from the Sparkfun hookup guide available here If enable is high the fets are off and nothing will happen, if sleep is low same thing (fets are off, motor does nothing). When you say “doesn’t work” that does that mean? Nothing at all happens with the motors? I’d check the state of the enable and sleep pins. idea is to use a touch screen interface to select boom sections and the location I want them to travel to.Īny hardware suggestions for the drivers?Ī quick look at the bigeasy says it should be easy to use. I intend to control the motors based on distance to travel. there is only one endstop which is for the nema 8. the motors work when connected directly to my mega board but not to the driver. I have a big easy driver but for some reason I can’t get it to work. I need to select hardware to control these motors. I have the idea of how I want to achieve the mechanisation of the telescopic boom.ġ_ 2 x micro steppers to control the retraction of a locking pin, the motors work simultaneously in parallelĢ_ 2 x micro steppers to control locking pins to pick up the boom section, the motors work simultaneously in parallelģ_ 1 x nema 8 to control the carrier that hitches to the boom section and moves it. I am a beginner and have a large RC Crane project on my desk.
