Hi,

I'm using Mach3. Where do I set this, please?

Config menu then motortuning. On the motor tuning screen theres an input box that says STEPS PER make a note of this number. Now on the right you will see Axis selection X,Y,Z click on which ever axis you want to change then enter the new number then and THIS IS IMPORTANT else it's any changes are not saved click on the SAVE AXIS SETTINGS button.

Depending whether you step up or down will determine the new steps per amount, so if original was 1/2 step and say 80 steps per and you go to 1/4 then just multiply the steps per x2 so would be 160. If 1/8 would be x 4.

Then re adjust the Accelleration and velocity sliders to tune the motors for best performance. TIP: Dont raise the Accelleration too high else will miss steps.
Just play around with the sliders untill your happy with it's performance BUT REMEMBER you must Click on the Axis then save every time you make a change.

Edit: The Steps per amount is the amount of steps it takes to move 1 measurement unit, not per revolution.
So if Mach set to metric units then it's steps per millimeter, if imperial then steps per inch
It's not steps per revolution.

Hi Tenson (Simon),
If you go on over to the GeckoDrive web site you will find a lot of info there that Mariss Friemanis has put up to teach people about steppers and their associated quirks. It makes for an interesting read when you are first starting out with CNC things and it explains a lot of details on how they work.

Here is the link

There is a lot to digest when you first start up and the good people here on the forum will guide you on the right path to success.
Rich.
