Q. System VERY slow to reach temperature
Envelope takes unusually
long (over 40 minutes) to
reach temperature.
1. Verify all covers and panels are properly installed.
2. Envelope heater(s) bad. Check heater resistance - should be about 36 ohms.
3. Replace PDB
R. Calibration Issues
Tip offset cal part - support
and model over 0.78" offset
1. Check that tip offset values are close to default values. default = 0.78, 0.00
Tip offset values change but
do not take.
1. Tip offset is changed in MaracaEX and the change is stored correctly in the hard
drive (verified by viewing the CFG file). When the tip_offset part is run though, the
offset does not change. Replace SBC.
S. Z Calibration Failure
First layer too deep into modeling base
Diagnostic details:
Left square (SS)
Upper layers - Missing
1st layer - May be visible, but looks choked off.
Etches may be visible in modeling base.
Right square (model)
Upper layers - Missing or barely stuck to model-
ing base. Part layer shifted.
1st layer - May be visible, but looks choked off.
Etches may be visible in modeling base.
1. Add +0.010 to Z offset value
First layer tip too high off modeling base
Diagnostic details:
Left square (SS)
Upper layers - Missing or barely stuck to model-
ing base
1st layer - Missing or barely stuck to modeling
base
Right square (model)
Upper layers - Missing or barely stuck to model-
ing base
1st layer - Missing or barely stuck to modeling
base
1. Add -0.010 to Z offset value
Support tip much lower than model tip
Diagnostic details:
Left square (SS)
Upper layers - Built OK
1st layer - OK
Right square (model)
Upper layers - Missing or barely stuck to model-
ing base.
1st layer - OK
1. Add -0.010 to Z offset value
