Setting up your software for the microstepping modes

Once your card has been configured for the microstepping settings , we need to calibrate the machine with the software. So, how do I apply this in the real world? well it is quite simple and only takes a couple of minutes. Depending on the model of stepper card you have the changeover for the hardware is easily obtained by installing jumper hats on the settings directly on the control card as illustrated in the picture below.For more detailed description see our blog entry for the hardware microstepping specifics.And remember that if you have a question or comment on this or any other blog entry or even on our website, feel free to drop us a line or to contact us through the contact form on this site.

 

 

Changing the settings on the software

First step is to calculate the physical properties of our CNC machine. we must know:

- How many steps per revolution do our stepper motors have?
- What is the pitch of our ball screw?
- What microstepping mode have we chosen?

If you have a Badog X model machine the answers are probably that the motor has 200 steps with 3mm pitch screw and a micro-step setting of 1/8

This means that we have 200steps*8times/3mm per rev= 533.3333333333 steps per mm or 1600 steps per revolution.

once we have calculated our steps per revolution, we have just to enter them into our program whatever we are using. For example in Mach3 you can open up the program then in config>motor tuning you will find the settings for steps per mm or alternatively if you are using the badog CAD with stepper accelerator you will put the steps per revolution in the options>startconfig> steps per revolution box.

 

 

 

 

 

Remember that you must change both the card and the software at the same time or the machine will not match the software indications. I hope this clears up a little on how to set up the microstepping modes on the different CNC control cards. and remember that if you have any questions or comments feel free to send us a message or drop us a line.
