Rostock MAX v2 User's Guide
This value dictates the number of steps that the stepper motor must rotate in order to feed 1mm
worth of filament to the hot end. The figure supplied will get your e-steps very close to ideal, but extra
fine tuning should be done. I highly recommend that you check out the “E Steps Fine Tuning” section
of Triffid_Hunter's excellent calibration guide. It can be found here:

The other portions of his calibration guide doesn't really apply to the Rostock MAX v2, so it's
not necessary to read unless you're simply curious.
WARNING: At no time should you allow your hot end temperature
to exceed 245C! The PEEK section of the stock hot end will melt
at 247C, requiring its replacement!
