How to change the direction of rotation of the motor?
« on: December 08, 2021, 05:34:57 AM »
Hello.

To change the direction of rotation of the motor, in the case of Mach3, I checked Reversed.
What should I do with Mach4?

You will find the "reverse" check box near the bottom of the Configure Control, Motors tab. In the list at the right side, you must highlight (not just check the box) for the motor that you wish to configure.

Is it the red frame in the photo?
Should I click the arrow to flip it to a red arrow?

The method that I offered should not require any configuration changes for your SmoothStepper.

The SmoothStepper provides additional places to configure all its pins and this often confuses people when both the Mach Configure Control and the SmoothStepper configuration offer duplicate ways to do things. You will need to know which pin is your direction signal if you plan to alter it in the SmoothStepper configuration, but that should also work.

I think your method is better.
I attached a photo.
What should I do if I know the check in the red frame?
Please tell me in detail.

Check in the red frame.
Then I clicked on the motor.
It looks like the picture.
Is that all right?

It looks like you got the right settings. Remember to click on "Apply" to store the setting.

Your motor velocity plot looks strange because your acceleration is very low with respect to your maximum velocity. The motor cannot get to the requested maximum velocity during the simulated test interval.

A normal plot will look like a ramp up, a flat "cruise" zone followed by a ramp back down to zero.

Hi,
another way to swap the direction of a stepper, without any programming, is to swap the polarity of one (just one) winding of the stepper.

Is this okay?

Hello Craig.
I use the circuit in the photo to change the rotation of the spindle motor.
I use it to cut screws.
The inside of the blue frame is the circuit that changes the direction of rotation.
