TIP COMPATIBILITY [2]
IDENTIFYING TIPS [3]
PLATEN VACUUM [4]
Make sure the vacuum indicator on the Operator Touchscreen
is green and showing that a small or large build sheet is in
place on the platen.
USING BUILD SHEETS [4]
Use clear build sheet for ABS-based, ASA, PC, PC-ABS, ST130.
Use smoky gray build sheet for ULTEM resin, PPSF, Antero.
Use green tinted build sheet for Nylon-based materials.
INSTALLING CANISTERS [4]
Remove the anti-rotation plug from side of canister before
use. Seal hole with sealing tape. Make sure the rubber
shipping insert is removed from the thumbwheel door
before building. Do not remove rubber shipping insert until
the canister is loaded into the canister bay.
Storing Canisters
Always replace the rubber shipping insert when storing a
partially used canister. Store canister vertically (as if it is
installed in a system) or cross-winding of the filament
on the inner spool may result.
CHANGING TIPS OR MATERIAL TYPE [4]
1. Remove the used build sheet from platen.
2. Clean the oven and tip wipe assembly.
3. Inspect the tip wipe assembly.
4. From the Build Screen, select Material/Tools and then select
Tips/Materials Change. Follow the screen prompts to
change tips.
The Tip Wizard will guide you through the process.

The system automatically does the following:
- Unloads model and support
- Waits for oven to stabilize
- Performs Auto Z Zero Calibration
- Performs Auto Tip Calibration
- Loads model and support material*
- Builds a Calibration Job*
* Requires button to be pressed by user and then user
placement to build the calibration box.
7. Select the circle next to the desired tip. A black dot in the
center indicates which tip is selected.
AUTO COOLDOWN FEATURE [4]
This option acts as an energy saver when PC, PC-ABS, ULTEM
resin, or PPSF materials are being used. It also helps to prevent
parts from cracking when building large, thick parts using PPSF.
After building completes, the oven gradually cools to the standby
temperature. Wait until the PPSF parts are cool before removing
them from the oven. To use this feature go to the Administrator
screen, select System Default and then set Auto Cool Oven
to On or after the job.
STABILIZING OVEN [4]
When changing material type or using Auto Cool-Down, allow
oven temperatures to stabilize before calibration and system
use. Oven stabilization times are as follows:
Table 1-3: Oven Stabilization Times (Software V.3.27 and later*)
5. When changing liquefier tips.
Note: Worn tips cause part quality issues and can lead to loss
of extrusion. Always replace tips when prompted (reset
tip odometers).
Make sure
tip is fully
inserted into
block
6. When changing material type:
- Remove the canisters. If removing a partially used
canister, you must remove it immediately (within ten
seconds) after separating drive block from canister; otherwise
the filament is forced into the canister, making it unusable.
- Seal the canisters and store vertically.
- Insert new canisters and turn the thumbwheel to put
the canister in the “Ready”
state (flashing LED).
- If the removed tips are to be
re-used later, record material
type and volume.
- Make sure that you insert the
tip fully into the heater block.
Note: If material type is changed, the tips MUST be changed.
Do not use the same tip for different material types.
- Select Review Materials to Load and choose materials to load.
- Select Menu to continue.
All unused model and support
tips are interchangeable -
EXCEPT for Soluble
Release (SR) support tips.
Once a tip is used, it is
committed to that material
type and is no longer
interchangeable.
Tip size is imprinted on
the top side of the plate
(T12, T14, T16, T20)
The Soluble Release
support tip is shorter
than standard tips.
Tip size is imprinted on
the top side of the plate
(T12SR20, T12SR30,
T12SR100).

CALIBRATING LIQUEFIER TIPS [5]
Calibration is an automatic step when changing material
type or tips. The user is still required to fine-tune some
steps manually.
Calibration Job
After the system builds the Calibration Job, follow these steps:
1. View the relationship between the support calibration toolpath
and the alignment indicators to determine the X and Y
axis calibration.
- Use a magnifying glass.
- Hold the build sheet up to the light, a light-colored wall, or
a light-colored piece of paper.
2. Determine where on each axis the support toolpath is most
centered between the X-Y alignment path. For example, if
most centered between indicators below the “4” on the “-Y”
side of calibration box, tip offset value for -Y is 0.004.
3. Slide the arrow on the screen to match where the support
is most centered. Only move arrows on two of the four sides
of the calibration part.
4. Press OK. A pop-up will be displayed asking if you want to
apply these values, press OK.
5. Repeat steps 1-4 until the support toolpath is centered
between all X and Y zero indicators. After adjustments are
made, a new calibration box can be run from this menu
by pressing Build Calibration Box.
6. Peel the Z box support layer from the last Calibration Job
and measure its thickness using a caliper or micrometer.
Z thickness should measure within +/-0.0005 in. (0.01 mm)
of the installed model tip’s slice height.
Note: Do not measure for Z adjustment until the Calibration
Model shows the XY Offset to be less than 0.002 inch
(0.05 mm) for the X and Y axis.
7. If Z thickness is not within specification, enter the value
read from the caliper/micrometer into the Support
Thickness field using the up/down arrows.
8. Continue to check for Z Calibration until the support layer
matches the model tip slice height +/-0.0005 in. (0.01 mm).
MAINTAINING TIP WIPE ASSEMBLY [6]
1. Open the oven door.
2. Using safety gloves and sleeves, remove the purge bucket.
3. Remove the purge ledge assembly.
4. Remove the brush/flicker assemblies.
5. Clean the purge bucket.
6. Clean purge ledge and brush/flicker assemblies and
surrounding area.
7. Inspect the Kapton tape around the top of the purge bucket.
8. Inspect the purge ledge assembly.
9. Inspect the brush/flicker assemblies.
- Empty canister (zero volume).
Replace the canister.
- Filament stuck in canister.
Remove the canister from the bay. Pull about
8 feet (2 meters) of material out, making sure the
filament pulls out freely.
- Canister drive block not fully lowered onto canister.
Re-seat the drive block onto canister.
- Wrong tip size selected on operator display.
Verify correct tip size is displayed. See Tip Compatibility.
- Canister smartspool circuit failed.
View filament status from the operator display. If the status
reads None or is blank, replace the canister.
- Broken or bent pogo pin.
Remove the canister from the bay and check the pogo pins
on the underside of the canister drive block. Replace any
bent or broken pogo pins.
- Filament does not reach head (load time-out).
Change the canister. If this fails, contact Customer Support.
Auto-Changeover Failure
Filament not unloaded into empty canister.
Perform a manual unload.
Note: All scenarios from Canister Will Not Load section
may apply in an Auto-Changeover Failure.
Loss of Extrusion
- Filament stuck in canister.
Remove the canister from the bay and pull about 8 feet
(2 meters) of material out, making sure the filament pulls
out freely.
- Canister drive too slow.
Verify that load time from the canister to the head switch
is less than 2.5 minutes.
Material not extruding on first two layers or model base.
Verify that material purges by performing a load.
Verify that the size of tip matches tip size indicated on
the operator display. See Tip Compatibility.
Verify that tip life has not exceeded the maximum tip
odometer.
Verify that the tips were installed correctly.
Verify that material purges by performing a load.
Replace the tip (if necessary).
System not calibrated.
Verify that material purges by performing a load. Perform
the Auto Z Stage Zero and Auto Tip Calibration.
Low vacuum caused build sheet to shift and may have
plugged tip.
See Low Vacuum.
Low Vacuum
Note: System will not build until the vacuum level is adequate.
- Misalignment.
Check the alignment of the build sheet making sure it is
properly paced on the platen.
- Bubble in build sheet.
Ensure that the build sheet is laying flat on the platen.
- Filament debris on the platen.
Clean the platen surface.
- Plugged platen inlet screens.
Clean the inlet screens.
Low Air Pressure
Contact Customer Support for assistance.
10. Replace parts as necessary.
11. Re-install parts in reverse order of disassembly.
EMPTYING THE PURGE BUCKET [6]
1. Open the oven door.
2. Lift the purge bucket straight up from the purge bucket bracket
and remove from the oven bay.
3. Empty the purge bucket by dumping the contents or using the
waste door at the bottom of the bucket.
4. Re-install the purge bucket.
