so i am just firing up my machine and testing out the steps put my ruler down on the waste board set the movement to 0.5" the Y axis went exactly to 0.5 but the x axis went to 7/16. sorry if i dont make sense i hardly know what i am talking about and if anyone could offer me advise in a dummed down form that would really help. ---

Can someone find the guide on adjusting steps per mm using phils calculator, I looked but just can’t seem to find it here anywhere… ---

@DarrylKegg I believe that Phil has requested removal of his material from this forum. You might be able to find him at this[link](http://www.designsbyphil.com/cnc-help.html). ---

Really, I wouldn’t think that could/would be done! ---

Find you current $100-value. Say it is 100. Current step / actual distance \* intended distance = **new step value** 7/16" = 11.1125mm 1/2" = 12.7mm 100 / 11.1125 \* 12.7 = **114.3** ---

Thanks, I know Phil had a detailed walk thru, Matthew is a new XC owner (of a previously owned XC) and needs to adjust steps. He’s not familiar with getting $ values, updating them etc… Phil’s calculator rocks, but Matthew needs the guided walk thru… ---

If you go to my website at [www.triquetra-cnc.com](http://www.triquetra-cnc.com) there is a link on the home page to download a free stepper calibration spreadsheet. Just fill in the numbers and run the test. It spits out the gcode to change the stepper calibration in GRBL. ---

really good point, most videos recommend an 800 or 900mm g0 move (on a 1k machine)… ---

> [@AngusMcleod](#): > > For what it’s worth, I would strongly recommend measuring a longer distance Indeed, for ultimate precision measure across the longest possible travel. I would however also suggest the following addition: Jog to the far left on X, then jog once 1/4" to the right - **then do the long measure towards the right.** Reason is to take system **backlash** out of the context. Backlash is present at any change of direction on the axes.
