Take a calliper and measure the length of the X and Y part and thickness (Z) of the print and write down the
numbers which in this example we call them PrintX, PrintY and PrintZ
The next steps can be a bit theoretical but when you take the time to master this you can hit a high accuracy.
In the console of your machine (LCD or web interface) type the following command:
M579 (press enter or click send)
You’ll get the result like this: Axis scale factors: X: 0.997, Y: 1.009, Z: 1.000
Rename this MachineX, MachineY and MachineZ to make the calculation.
If the dimensions are right the PrintX and PrintY side of the print would be 100mm and the PrintZ height would
be 10mm. In this example your print as PrintX=99.82mm and PrintY=100.33mm and PrintZ is correct.
Formula for dimension calibration
To calculate the scaling factor, we need to do the following steps:
PrintX / MachineX = RealX
(99.82 / 0.997 = 100.12mm)
PrintY / MachineY = RealY
(100.33/1.009 = 99.435mm)
Now we know the real machine values we can calculate the new dimensions:
100 / RealX ( = 0.9988)
100 / RealY ( = 1.0057)
This number is our new scale factor, in your slicer would be Scale X to 99.88% and Scale Y to 100.57%
