The last task you'll need to perform before you can load plastic in to the machine is to correctly
set the steps per mm ("E-Steps") for the extruder. Open up the EEPROM configuration editor and look
for the label highlighted below:
The value should be set to 92.65. If you're using the older Steve's Extruder, this value should be
set to 584.
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 figures supplied will get your e-steps very close to ideal, but
extra fine tuning can't hurt. 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.
