ProX 500 START-UP SEQUENCE
If you’re starting the printer from it’s powered-off state, you must first perform the following machine start-up sequence before you start
a print:
•
Start the chiller
•
Verify the system’s compressed air
•
Verify the system’s nitrogen supply
•
Verify the system’s material supply
•
Put Sinter in Manual Operations (Man Ops) mode
•
Move the part piston to its Home position
•
Move the roller to its Home position
•
Move the piston back to its Start position
Instructions for each step in this sequence are described next .
If you’re starting the printer from its powered-off state, do not attempt to start a print before you perform the startup
sequence . Also, never attempt to start a print if the dsp button is not shown in the taskbar . (Putting Sinter in Build
mode then opening a build packet starts a build .) - see latest customer release notes for starting Sinter and system
(dsp) initialization .
1 . Start the Chiller .
a . Press the power (
I/O
) button on the chiller front panel .
b . Check that the chiller
COOLANT INLET
flow gauge at the SLS system gauge panel reads 6 lpm or more.
c . Check that the chiller temperature setpoint is 20C .
2 . Verify the printer’s compressed air supply .
a . Verify that facility compressed air is on and connected to the gauge panel
AIR INLET
.
b . The air pressure gauge label indicates the correct reading . This should be: 500 KPa (72psi) .
3 . Verify that the system has an adequate supply of nitrogen and that it is running .
NOTE: Skip Step (a) if you have a nitrogen dewar or bulk tank connected to your SLS system instead of a nitrogen
generator .
a . Open the compressed air supply valve at the bottom of the N
2
generator .
b . Make sure the
NITROGEN INLET
ball valve on printer’s gauge panel is open . It needs to be turned at a 90° angle so that
it is aligned with the direction that the nitrogen is flowing.
c . Verify that the regulated
N
2
PRESSURE
gauge on gauge panel reads 140 KPa (20psi) .
4 . Verify the material supply using either of the following two ways .
•
In SinterDiag, check the MQC window in the Man Ops screen . This displays the MQC System’s status, including the amount of
available powder .
or . . .
•
Check the MQC status in the Sinter Status window which also displays the amount of available powder .
