Warning: Hot Surface Hazard Always wear proper heat protective gloves and clothing when handling items inside the oven, as surfaces within the oven can be very hot. |
The purge chute is designed to guide purged material debris from the tip wipe assemblies to the bottom of the oven chamber for disposal. Purged material debris then collects within the bottom of the oven chamber, beneath the platen. Do not allow excess material debris to accumulate in the oven chamber as this could cause damage to the printer. Clean the oven chamber on a weekly basis to remove build material debris and dust. A standard vacuum can be used to clean this area if needed. If excessive accumulation occurs vacuum the oven chamber as needed.
The steel platen provides the level surface on which parts are built (see Figure 7 (page 7) for platen overview). A substrate is securely affixed to the platen by the substrate ejection handle. If debris collects on the platen, it can adversely affect substrate adhesion.
1.Remove the substrate from the platen.
•Push down on the substrate ejection handle to release it from the platen.
•Slide the substrate from the platen.
2.Carefully remove purged material debris that have fallen into the openings of the platen.
•A standard vacuum can be used to clean the platen.
Clean/Inspect Tip Wipe Assemblies
The tip wipe assemblies should be cleaned once a month. While cleaning the assemblies, inspect the flicker/brush assemblies for wear and replace as necessary when wear is detected.
Once material is purged from a tip, the flicker portion of the tip wipe assembly passes across the tip’s opening, cutting purged material off in small segments. The brush portion of the tip wipe assembly then passes across the tip’s opening cleaning the tip and its tip shield. As a result, the flicker will wear at the location where the tip contacts its surface and eventually develop a notch large enough for the tip to completely pass through the flicker; a notched flicker cannot properly cut purging material. Similarly, material can become embedded within the bristles of the brush resulting in clumping; clumped bristles cannot properly clean a tip or its tip shield. The tip wipe assembly should be replaced once a significant notch develops within the flicker portion of the assembly or whenever bristle clumping (which cannot be removed with a brush) is apparent within the brush portion of the assembly. The tip wipe assembly is replaced as a single unit.
To clean the tip wipe assembly and inspect its components:
1.Ensure that the printer is stopped (idle) and is not building.
|
|
Caution: Depending on how long the oven has been allowed to cool, components may be hot. Wear the safety gloves provided in the Welcome Kit to perform all remaining steps. |
3.Remove the model side tip wipe assembly by lifting it upward until it clears its locating pins.
Figure 19: Tip Wipe Assembly Removal
4.Repeat step 3 above to remove the support side tip wipe assembly.
|
|
If the head is positioned above the purge area it may impede your ability to remove the tip wipe assemblies. Open the top cover and manually move the head away from the purge area. |
5.Clean and inspect the surface around the locating pins. Make sure that the tip wipe assemblies can sit flush on the surface.
6.Inspect the flicker portion of the tip wipe assemblies. The top edge of the flicker should be straight and must not contain excessive notching/wear.
7.Inspect the brush portion of the tip wipe assemblies. Brush bristles must not show evidence of wear (i.e. no notches in bristle pattern) and should not contain significant bristle clumping. Frayed bristles are acceptable as long as the top edge is even across all of the bristles.
8.Replace one or both of the tip wipe assemblies if excessive wear is present. See Table 2 (page 11) for information on ordering replacement assemblies.
|
|
The components of the assembly cannot be replaced individually. The entire tip wipe assembly must be replaced if excessive wear is present on the flicker or the brush. |
Figure 20: Tip Wipe Assembly Details
9.Reinstall the support side tip wipe assembly by placing the assembly onto its locating pins and sliding the assembly downward.
10.Repeat step 9 above to reinstall the model side tip wipe assembly.
Cleaning the Exterior Surface of the Printer
The printer’s exterior surfaces (doors and panels) may accumulate dust and periodically require cleaning. Exterior doors and panels, with the exception of the touchscreen display, can be cleaned using a slightly damp microfiber cloth (supplied in the Welcome Kit). The cloth should be only slightly damp to ensure that water does not enter the printer. Excess water can cause damage to interior components.
Cleaning the Touchscreen Display
|
|
Caution: Using a cleaner which contains ammonia and/or alcohol can damage the touchscreen. Only a suitable LCD cleaning solution and microfiber cloth (included in the Welcome Kit) should be used to clean the touchscreen display. |
As needed, to remove smudge marks and buildup, clean the touchscreen display using the LCD cleaner and microfiber cloth provided in the Welcome Kit.
Apply an adequate amount of LCD cleaning solution to the provided microfiber cloth and then gently wipe the exterior surface of the touchscreen display to clean its surface. It is recommended that you apply LCD cleaner to the microfiber cloth rather than applying cleaner directly to the touchscreen display, as excess moisture may damage the display.
Inspecting and Cleaning the Tip Shields
The tip shields may accumulate purged material or debris. As required, this material can be removed by manually wiping the tip shields with a clean cloth.
|
|
When printing with TPU 92A material, it is recommended to make sure that the tips and tip wipes are clean and free of debris before starting a part build. |

When a head reaches the 1500 build hour odometer limit (800 hours for a TPU 92A head or 700 hours for an ABS-CF10 head), a warning will be displayed on the User Interface and the head’s Head Status Icon will be highlighted in red on the Materials page. You can continue using a head which has exceeded its odometer limit, but it is highly recommended that you change the head as part quality will be unpredictable. See “Replacing a Head” (page 12) for instructions on replacing a head. Replacing an ABS-CF10 head is the same as replacing a standard head.
The process for replacing a PLA head varies slightly from the process for replacing a standard head. When building with PLA material a specialized PLA head is used. The PLA head must be installed into the model head location within the gantry. A cooling module is used in conjunction with the PLA model head and must be installed into the support head location within the gantry. The PLA model head extrudes both model and support materials. See “Replacing a PLA Head” (page 14) for instructions on replacing a PLA head or the associated cooling module.
