X Y Z axis calibration and skew correction for all Bambu Lab 3D printers in Bambu Studio

In this video I show you how to calibrate the X Y and Z axis and make skew correction for all Bambu Lab 3D printers with Bambu Studio.

Here is the link to the square calibration stl:

I made the calibrations for my Bambu Lab A1 but it should also work for the A1 mini , the X1 , X1C , X1E , P1P and the P1S.

If you want to print dimensionally accurate, functional parts that really fit, you need to calibrate the x, y and z axes.

While there are several, mostly automatic, options for calibrating the filament flow on Bambu Lab printers, you will search in vain for a reasonable calibration of the x, y and z axes.

An equally necessary skew correction is also not so easily possible.

In this video I show you how to make the corrections to print dimensionally accurate mechanical parts in the future.

I want to print a bidirectional impulse turbine whose turbine wheels require the most accurate manufacturing dimensions possible.

I have therefore tried to set up my Bambu Lab A1 as accurately as possible.

However, all the measures shown should work with all Bambu Lab printers.

Of course, all the parameters such as filament flow, temperatures, print speeds, retract and even the mechanical settings such as the printer's belt tensions must first be set to perfection.
Only then does further optimisation with x,y,z calibration make sense.Here are the exact step-by-step instructions:
First, print a calibration cube of at least 30 mm.
.After printing, as always, it is very important to allow the prints to cool completely on the printing plate before removing them.
Then measure the x,y and z lengths, preferably with a good caliper, and divide the target dimension (30mm in this case) by the respective measurement result.
In the printer settings, select the machine gcode tab and enter the sentence below at the very end, with your values of course.
You then print your calibration model again with these inputs and the dimensions should be better.
This method intervenes heavily in the kinematics of the printer and is only suitable for fine tuning in the tenth of a millimetre range.
It is also possible to use the M500 command to store the calibration values permanently in the printer's memory.
To correct the skew, please print out the SquareCal.stl file, the link to which can be found in the Contributions section of my channel page.
Then measure the lengths X and Y with a caliper.In the last line of the machine start code, enter the record below with your values.
With the methods presented here, I get much more dimensionally accurate parts that fit together and work better.

Thanks for watching and have fun printing!
