N. “Can't Find Home - Check Modeling Base” displayed on LCD
Head stops over Z stage/
modeling base
1. No modeling base
2. Modeling base is used/defective - Replace
3. Verify substrate sensor is working properly, verify at LED/test points on PDB.
4. Substrate sensor is loose or defective, tighten or replace.
Head moves to lower mod-
eling base sensor but does
NOT move over modeling
base
1. Modeling base sensor is NOT turning off before performing touchdown (verify
using LED)
2. Y EOT sensor is not operating correctly. Verify using LED/test points on PDB.
3. Debris on Z Stage casting prevents Z stage from finding home
Head completes finding
modeling base routine then
displays error message.
1. Modeling base is used/defective - Replace
2. Z offset value is incorrect (out of operating range) Check/adjust value using
MaracaEX or download CAL file from CD to restore factory calibration values.
3. Flatness check may have failed. Use TeraTerm to read the touchdown values.
Compare these values to the “tolerance” value displayed. If this value is over
1728 replace the modeling base.
4. If failure reoccurs check XY table level using the head bracket and dial indicator.
The tolerance from the fixed corner is +/- 0.0015.
- If values are out of spec: Check for loose tray mounting screws. If so level per
procedure.
- If screws are tight, level the XY table per procedure.
5. If failure reoccurs the X rear guide rod may be out of alignment. Replace XY
table.
Head stops moving while
attempting to lower Z
detect sensor plunger
1. Using PDB LED's check to see that all sensors are working correctly. If not check
sensor connections/wires or replace sensor
2. Z offset value is incorrect (out of operating range) Check/adjust value using
MaracaEX or download CAL file from CD to restore factory calibration values.
O. Power Down
Fails to shutdown.
1. Toggle the power switch again. Wait 5 minutes
2. Shut system off at the breaker.
Display indicates “Recovery
after uncontrolled shut-
down”
1. AC power was interrupted. Check customer AC power.
2. Bad power switch cable.
3. UPS malfunctioned, replace UPS.
Display indicates “Recovery
after controlled loss of
power”
1. AC power was interrupted. Check customer AC power.
2. UPS wiring is incorrect. Check wiring
3. UPS malfunctioned, replace UPS.
Shuts down immediately
after the power switch is
thrown.
1. Replace the SBC.
2. Replace the PDB.
3. Replace power switch.
Shuts down after part is
complete
1. Auto power down was enabled, normal operation.
