paper towel�
11.2 Lubrication
The SIMPLEX 3D filament printer should be lubricated at least once after every 50 hours of opera-
tion or every 6 months.
Only lubricate the following parts:
For the print bed:
• Guide rods of the z-axis
• Threaded rod of the z-axis
For the print head:
• Guide rods of the x and y-axis
The following tools are required for lubrication:
• PTFE-based spray lubricant or grease
• 2 lint-free cloths or thicker paper towels
• Gloves and safety glasses
• Light to adequately illuminate the interior of the SIMPLEX unit.
11.2.1 Lubrication of the z-axis
The guide rod and threaded rod of the z-axis are located inside the printer at the rear.
⇒ Select the AXES
⇒ Adjust the print head and the print bed to the home position
⇒ Switch off the printer and disconnect the power plug.
⇒ Slide a folded paper towel or lint-free cloth between the threaded rod and the back to protect other
areas of the printer from any overspray that may occur�
⇒ Spray the threaded rod at a relatively short distance to avoid overspraying. Ensure that the lubricant
reaches the inside of each thread� If you use grease, use gloves to spread it�
⇒ Be careful not to over-lubricate, only spray the minimum amount required�
⇒ Do not spray the two guide rods directly! Spray the lubricant onto a cloth and use it to lubricate the
guide rods�
⇒ Remove the cloth�
