Calibration Test 40x40x40

This is a calibration test 40mm for xyz axes.
To calibrate your 3D printer, you need to print a first time this test and to measure all axes with a caliper.

1 - Connect to your printer with Pronterface or OctoPrint
2 - Send M503 and collect M92 steps/mm values for X, Y and Z
3 - Do the following operation for each axe :
New X step/mm value = (40/Measured X) * old X steps/mm value
4 - Send the following commands to your printer :
>M92 X[new_steps/mm_value] Y[new_steps/mm_value] Z[new_steps/mm_value]
this one is to give new values to your printer
>M500
this one is for saving your configuration.
5 - Print a new calibration test to check if X = Y = Z = 40mm

You can do this a second time if measures are not exactly correct.
Average accuracy is near to 0.1mm on our 3D printers.
