Most of these procedures are only performed whenyou are prompted to in the 3DPrint Maintenance dialog. Others should be performed at the recommendedfrequency detailed in each procedure below.6.1 The Maintenance DialogThe Maintenance dialog (found on the 3DPrint Tools 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 in3D 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 is required to keep these parts workingoptimally. 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.6.2 Fast Axis Bearing LubricationFrequency: When prompted in 3DPrint, or when you receive Error 2303-1.1. Before lubricating the Fast Axis, make sure the rails and carriage are clean. Follow the cleaninginstructions in the Routine Cleaning chapter.2. Assemble the grease gun that is part of your Accessories Kit according to the instructions found in thedocument 09576 Grease Gun Loading Instructions, which is supplied on the software installationmedia shipped with the printer. You can also find these instructions on our Web site at3dscentral.3dsystems.com.3. Squeeze the handle until grease dispenses from the tip. Wipe clean with a clean paper towel.4.
