Renkforce RF2000 v2 Series - C) Setting the Distance between the Nozzle and the Printing Plate

31
c) Setting the distance between the nozzle and the printing plate
Only the left extruder (viewed from the front) (extruder 0) is used for calibration in the dual extruder. The distance between the nozzle
and the heating plate must be set to 0.3 mm.
Important! Determine the position with the smallest distance between the nozzle and the heating plate in the cold condition. The basic
settingoftheupperZ-limitswitch(Z-min.;lightbarrier)alsotakesplaceinthecoldcondition.Thismeansthatiftheextrudersorthe

Ifyouhaveacquiredanisheddevice,checkwhetherthedistanceisbetween0.8mmand1.0mmwhendeterminingthe
highest position of the printing plate. If applicable, repeat the "basic setting of the upper Z-limit switch (Z-min.; light bar-
rier)" on the next page.
Attention! Never touch the hot extruder or the printing plate during the settings! There is a danger of burns!
Determining the position with the smallest distance
First move the printer Z-axis to its home position (Home Z).Briey
push the button OK (2) in the main display.
Use the direction buttons (1) to navigate to menu item "Position".
Push OK. Use the direction buttons to navigate to menu item "Home Z".
Push OK, to move the printing plate to the Z-Home position.
Attention! The extruders must not touch the printing
plate during the subsequent setting. If this is the case,
lower the Y-plate a little with the arrow button "down"
(3) and turn out the actuation for the Z-stop a little.
Now determine the position on the printing plate where the distance
between the nozzle of the left extruder and the printing plate is small-
est. For this, target the 9 positions that are marked at the top of the
picture. For this, carefully move the extruder carriage and the printing
plate by hand. It is easiest to determine the right position with a feeler
gauge.
Leave the extruder carriage and the printing plate in the position
where you have determined the smallest distance.
