Extra stepper motor don't move

eric78

Hello,
I use the version 0.92.9 and a Mega / ramps 1.4 card
I added a step motor and when I run the gcode G201 P0 X10 engine does not move and gets stuck.
In config.h

#define MOTOR_DRIVER_1 (var) StepperDriver <42,44,40,0,0> var (2560.100)

I tested with var (200,100) also.

Do you have an idea.
Thank you
Eric

#define NUM_MOTOR_DRIVERS 0

// #define MOTOR_DRIVER_x StepperDriver<int stepPin, int dirPin, int enablePin,bool invertDir, bool invertEnable>(float stepsPerMM,float speed)

#define MOTOR_DRIVER_1(var) StepperDriver<E1_STEP_PIN, E1_DIR_PIN, E1_ENABLE_PIN, false, false> var(100.0f,5.0f)

Also in brackets you need to separate with , not with . as you did. Last thing is speed. This all works without acceleration so only slow speeds are supposed to work, not speeds like 100mm/s. That will give you only a humming motor and loose all steps.

</e1_step_pin,></int>

Thank you for your reply but with #define NUM_MOTOR_DRIVERS 0
I get Unknown command: G201
So I tested with #define NUM_MOTOR_DRIVERS 1
and invertEnable true and false, the engine still does not move; + (

"#define NUM_MOTOR_DRIVERS 1
// #define MOTOR_DRIVER_x StepperDriver <int Steppin, dirPin int, int enablePin, invertDir bool, bool invertEnable> (float stepsPerMM, float speed)
#define MOTOR_DRIVER_1 (var) StepperDriver <59,64,63, false, false> var (100.0f, 5.0f) "

I use G201 P0 X10 to test with Repetier-Host V1.6.2

Thank you

Sure, NUM_MOTOR_DRIVERS 1 is correct. I had it on first enter and forum destroyed it and on recopy I forgot to correct.

Just had a look into code and M201 does NOT enable/disable motors. You do this with

G204 P<motorId> S<0/1> - Enable/disable motor

So run first

G204 P0 S1

then it should move.

I tested "G204 P0 S1" and "G204 P0 S0" with "G201 P0 X10" still nothing!

I'll test by adding a third extruder.

Good Sunday

Hello,
this is it works!
by creating a third extruder.
I added in pin.h

"#define ORIG_E2_STEP_PIN 63
#define ORIG_E2_DIR_PIN 64
#define ORIG_E2_ENABLE_PIN 59
....
#define E2_PINS ORIG_E2_STEP_PIN, ORIG_E2_DIR_PIN, ORIG_E2_ENABLE_PIN, "
and changed the configuration EEPROM.

// #define MOTOR_DRIVER_x StepperDriver <int Steppin, dirPin int, int enablePin, invertDir bool, boolinvertEnable> (float stepsPerMM, float speed) #define MOTOR_DRIVER_1 (var) StepperDriver <63,64,59, false, false> var (100.0f, 5.0f) "

would then be the correct solution. You have toggled order for step and enable pin!

The final version is:

#define MOTOR DRIVER v1 (var) Stepper Driver <63,64,59, false, false> var (200.0f, 1.0f)

because 200.0f for one revolution and 5.0 is too fast.

Thank you
Eric
