ESP32 All enable pins for separate steppers on for longest stepping duration

[plpers]

Per Issue #155, I am finding the same behavior as this issue, where if I have stepper1 running for 1000 steps, and stepper3 running for 5 steps, stepper3's enable pin stays on until stepper1 completes executing it's commands.

here is a code snippet below. When i look on the oscilloscope I cant get stepper 3 enable to stop running.

include "FastAccelStepper.h"

include

define dirPinStepper1 21 //24, PA2

define enablePinStepper1 19 //22, PA0

define stepPinStepper1 26 //26, PA4

define dirPinStepper2 33 //24, PA2

define enablePinStepper2 32 //22, PA0

define stepPinStepper2 25 //26, PA4

define stepPinStepper3 27

define stepPinStepper4 18

define conveyorPin 23

define flywheelPin 22

FastAccelStepperEngine engine = FastAccelStepperEngine(); FastAccelStepper stepper1 = NULL; FastAccelStepper stepper2 = NULL; FastAccelStepper stepper3 = NULL; FastAccelStepper stepper4 = NULL;

void setup() {

engine.init(); stepper1 = engine.stepperConnectToPin(stepPinStepper1); stepper2 = engine.stepperConnectToPin(stepPinStepper2); stepper3 = engine.stepperConnectToPin(stepPinStepper3); stepper4 = engine.stepperConnectToPin(stepPinStepper4); if (stepper1) { stepper1->setDirectionPin(dirPinStepper1); stepper1->setEnablePin(enablePinStepper1); stepper1->setAutoEnable(true); // If auto enable/disable need delays, just add (one or both): // stepper->setDelayToEnable(50); // stepper->setDelayToDisable(1000); stepper1->setSpeedInUs(1000); // the parameter is us/step !!! stepper1->setAcceleration(1500); stepper1->enableOutputs(); } if (stepper2) { stepper2->setDirectionPin(dirPinStepper2); stepper2->setEnablePin(enablePinStepper2); stepper2->setAutoEnable(true); // If auto enable/disable need delays, just add (one or both): // stepper->setDelayToEnable(50); // stepper->setDelayToDisable(1000); stepper2->setSpeedInUs(1000); // the parameter is us/step !!! stepper2->setAcceleration(1500); stepper2->enableOutputs(); } if (stepper3){ stepper3->setEnablePin(flywheelPin); stepper3->setAutoEnable(true); stepper3->setSpeedInUs(1000); // the parameter is us/step !!! stepper3->setAcceleration(1500); //stepper3->setDelayToDisable(1); //stepper3->enableOutputs(); //nuked so it doesnt boot firing and shit } if (stepper4){ stepper4->setEnablePin(conveyorPin); stepper4->setAutoEnable(true); stepper4->setSpeedInUs(1000); // the parameter is us/step !!! stepper4->setAcceleration(1500); //stepper4->setDelayToDisable(1); //stepper3->enableOutputs(); //nuked so it doesnt boot firing and shit } }

void loop() { // put your main code here, to run repeatedly: stepper3->move(20); stepper4->move(20); stepper1->move(2000); delay(4000); }

additionally, if i attempt to enable/disable outputs based on an individual stepper being stopped (e.g. stepper->isRunning) it stops all the other motors.

Thanks for sharing the code. Before hunting any ghosts, are you by any chance using Arduino IDE with its buggy library manager ? Arduino IDE only offers installation of 0.30.0 and there is a related bug fix implemented in 0.30..5.

hi @gin66 - yes that works now. Yes, I am using the arduino library manager, and it was 0.30.0. since I'm working with kids. I manually installed from github and it works great now! thanks for providing a great library.
