When you're done, click the Close button on the Macro Editor. The CONTROLS screen
should now have a macro display that looks like the figure below.
The macro will become a button you can click on. DO NOT CLICK IT YET.
In order to make the calibration as accurate as possible, you'll need to bring both the heated bed
and the hot end to operating temperature. Set the Extruder temperature to 190C and the Bed
temperature to 55C just as you did for setting the Z height.
Open the EEPROM editor and check the values shown below. If the Diagonal Rod Length
parameter isn't set to 290.8, please change it to that value. The starting position for the Horizontal
Radius is 144. [If you're working with an older v2 or v1 with the u-joint based arms, your Diagonal
Rod Length should be 269 and your starting Horizontal Radius should be 130.25]

Make sure you save your changes before you move on.
In order to help you calibrate the Rostock MAX v2, SeeMeCNC has created a neat video that
illustrates the entire process from beginning to end. In the video they're using the SeeMeCNC Orion
printer, but the technique is the same for the Rostock MAX v2. When you see reference in the video to
running the "TOWER.GCO" file, you'll instead click on the Tower Cal button that you just created the
macro for. They're the same thing, just executed differently.
When you click on the Tower Cal button, it will execute the script you just entered. The script
will move the nozzle to 0.2mm above the center of the build plate and pause for five seconds. It will
then move to the X tower, then the Y tower, then the Z tower, and finally will return to center.
You may notice an odd "arc" motion as the nozzle travels from point to point. This is a
mathematical phenomenon within the firmware and won't affect your calibration. You can safely
ignore it.
