The error will always be linear (unless your head shimmies from side to side as it slides down - which thinking about might be worth doing it with a 'tight' Z axis just to make sure). The only reason to make the measurements as far apart as possible is to magnify the results. Because it is a linear error once you fix it it'll be valid over the entire range. I know what you mean about the explanations though, it's a fairly simple thing but to read some of the online explanations you'd think it was rocket science. I had to read one of the explanations several times before it suddenly clicked! |

welp it took me these few minutes to get the up and down under .0005" deviation. now time for the x axis. Scratch the above still got a deviation. |
| krymis:
so i now have checked this 3 times and get the collet to 0 out. I then move tot eh end of the rod and get -.0035 down and .002 up so my math ([(-.0035+.002)/2]) i come up with -.00075. Does my math look correct and I think this is good for this little thing or do you guys think i need more tweaking? |
| kwackers:
Looks good to me. Over that length (same as the video?) the error sounds pretty good (to me). I wouldn't like to say what an acceptable error is, my mill has a tilting head and tbh I tram it quickly with a dial gauge against the table - probably to no better than a thou or so. Obviously having a fixed head I guess there's more point to spending a bit of time with yours. |
| krymis:
so i got the x set up and according to my math i am -.00025 with 2 different readings. I think this is good enough. |
