7.2.2 Precondition for calibrate the machine

➠ Start SITEST.

➠ Under menu item "Main view", click "Overall reference run", to reference all gantry- and head-

axes.

➠ Configure the nozzle changer and filling level

–

Precondition for calibrate the nozzle changer

C&P head (6/12/20) :

(1) Every magazine of the nozzle changer has to be configured with a nozzle type.

(2) No nozzle on segment 1.

(3) There must be minimum one nozzle present and configured (1) in garage 1 of every magazine.

TWIN- head : (1) Garage 1 of the nozzle changer has to be "empty"

(2) Both nozzles at the TWIN head has to be configured.

NOTE : For C&P12 head it is also possible to configure every magazine "empty" and the head

"full" of nozzles.

➠ Check the zero point correction D-Axis Twin head

➠ Check the zero point correction Z- and Star Axis with the Sitest at the C&P20 head,

if necessary or an error message appears.

7.2.3 Determination of Z- and Star axes zero point correction (Sitest) :

NOTE : Determination of Z- and star axes zero point correction is only offered if the zpc- values

of the Achs_ver.ma and the EPROM (head) are not the same.

Are the value identical appears the following message:

– Start the Sitest --> Head functions

The values are not identical, you have to calibrate the zero point correction and the following mes-

sage appears:

Check the position of the Z-Axis and press Yes.

– Follow the Information and press the Start button on the maschine.

–Press OK

Now the head is calibration the Z- and Star zero point correction and save the new values in the

Achs_ver.ma and the Eprom.

Function description: 7

– The Z-Axis move up with the current sensor mode and set the counter to 0.

– Then the Z- axis moves down to 18000 digits until the ball bearing of the Z- axis is between the

raceway of the star axis.

– The star turns left and right and calculated the average value. This is the new zero point cor-

rection (

zpc) value of the star axis.

– The Z- axis moves further down until the ball bearing (Segment) is in the center of the raceway

gap.

– The star turns right into the gap of the raceway and the Z- axis push up the ball bearing against

the raceway. The Z-axis position is read.

– Now the Z- axis position is read on the left side from the raceway gap with the same procedure,

like the right side.

– Afterwards the new zero point correction of the Z- axis is calculated in the following way :

Z- position - diameter ball bearing - thickness of the raceway = new zpc Z- axis

NOTE : The data is directly stored in the Achse_ver.ma and at same time the data is written in the

EPROM of the head.
