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…
I believe that Phil has requested removal of his material from this forum. You might be able to find him at this link.
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 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)…
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.
