How often do you lubricate the linear guides?
How often do you lubricate the linear guides?
I am curious how often do you service the linear rails on the 3D-printer:
- How often do you lubricate them (MGN9 or MGN12)?
- How do you lubricate them?
- What volume of lube do you use?
Explanation of how often you should do it (HIWIN Lubricating instructions for linear guideways and ballscrews)
Most 3D-printer use MGN12. Reading the HIWIN documentation they shall be lubricated every 20-50km (depends on a lot of factors).
How much is 50km in print time? Assuming an average speed of 300mm/s that would be approx. 46 hours!
In other words, the generic MGN12H carriage needs 1-2 times per week maintenance.
How much lube is suggested (horizontal mounting)? 70µL for MGN12H. For MGN9H it is 30µL!

Currently my mk4 is printing pretty much 24/7 with IS profiles. I'm applying some lubricant roughly once per week - sometimes I notice the printer starts making strange noises, mostly I notice when rods have zero residue between prints, and just add a bit.
Don't forget to recite the scripture when applying holy oil to the machine brother. Omnissiah protects.
