Printer Maintenance
This chapter details how to perform maintenance on your printer and how to prepare your printer for stor-
age if you will not be running it for extended periods. Most of these procedures are only performed when
you are prompted to in the 3DPrint
Maintenance
dialog. Others should be performed at the recommended
frequency detailed in each procedure below.
The
Maintenance
dialog (found on the 3DPrint
Service
menu) keeps a record of when the Fast Axis bear-
ing
,
the Slow Axis bearing, and the Piston Screw require lubrication. 3DPrint will prompt you when lubrica-
tion of any of these components is required.
Only lubricate these components when you are prompted to in
3D Print
.
While lubrication of these items is important, it is equally important not to over-grease the bearings and pis-
ton screw when lubricating. Only a very small amount of grease or oil is required to keep these parts work-
ing optimally. Over-lubricating creates a situation where lubricant builds up in places where it should not
be, and may cause the printer to report an error.
6.1 Fast Axis Bearing Lubrication
Frequency:
When prompted in 3D Print, or when you receive Error 2303-1.
1.
Open the printer top cover and pull the fast axis forward until it stops.
2.
Lay clean paper towels under the left end of the Fast Axis.
3.
Cover the Front Overflow with paper towels.
4.
Using a paper towel dampened with distilled water, wipe the top and bottom Rails to remove any Core.
Move the Carriage back and forth as needed to clean the entire length of both rails.
5.
Dry both Rails thoroughly with a clean dry paper towel.
6.
Using a fresh paper towel, wipe the Carriage to remove any Core.
7.
Locate the Fast Axis oiling hole, located in the top of the Fast Axis near the left end.
8.
Make sure there is no Core visible inside the hole or on top of the Fast Axis.
9.
Lift up the hinged cap that covers the oiling hole.
10. Using the oil supplied in your Accessories Kit, place 5 drops of oil into the small reservoir. Do not over-
fill. Close the cap.
