JET3up Release R1.06
8.5.2.6.3 Sensor monitoring
With this function the print-control of the PrintGo sensor is complemented with a
second sensor. The first sensor delivers the PrintGo signals and the signals of the
second sensor are used for double-check. The two signals haven’t to be present
exactly at the same time, but they have to overlap at any rate. The function is
activated by a checkbox on the <PrintGo Parameter> tab.
Figure 147 Sensor monitoring - Settings
The second sensor is connected to the PrintGoGate input of the JET3up printer.
The PrintGoGate function will not be available if a second sensor is used for the
PrintGo monitoring.
With the sensor monitoring activated two further functions will be monitored:

Monitoring of the StrokeGo signals. These are the signals of a connected
encoder.

Monitoring of the ready-for-printing status. If there are PrintGo signals,
StrokeGo signals (encoder signals) or signals from the second sensor received it
will be verified whether the printer is ready for printing.
With activated sensor monitoring (Sensor (PG+Enc.)) each of the following cases
will cause an error message. Figure 148 shows the timing diagrams.
1. Either the PrintGo sensor signal, the signal of the additional sensor or both
are missing or have the wrong timing.
