Cut Accuracy off slightly?
I have listed the steps to adjust the step length. A vernier caliper that will read in mm makes this process easier. (and you really need to enter dimensions using 2 decimal places 0.00 mm)
I prefer to cut a thin piece of wood 100mm x 100mm to ease the data input - if you cut a larger square you must correct the value entered into the block shown in the pic because it is really a percentage....so using a 100mm square removes the need for additional math.
If you perform this process 2 or 3 time you will find the accuracy gets better and then worse. That is a function of the machine trying to over correct for an accuracy that exceeds capability of the steppers/servos/belts etc. when you get to 99.94mm or there about I recommend calling it good(the error at that point is 0.0023" for those that use the old system-like me).
You might be able to get to 99.98. But with a beam size of 0.004 -0.006 you are not likely to see the difference.
Don't forget to READ and then WRITE
After validating the precise movement of you machine check the reverse interval following the process in the link below
