Preventative Maintenance Schedule

All,

My company has been running a print farm for several years. We are retiring our Lulzbot Taz printers. They have been very labor intensive and unreliable for 24/7 printing. Side note: never use Lulzbot printers for industrial scale printing. You will have a bad (and expensive) time.

We have been directed to Prusa for the quality, support, and reliability of its printers.

Does anyone have a preventative maintenance schedule for this printer? 

Use: 24/7 intricate parts using PLA exclusively

I am creating a list for our operators to replace parts on a scheduled basis and to check for failure. 

For example:

How often to check for bed leveling?

Are there fasteners prone to loosening?

How often should the nozzle and heat brake be replaced (using PLA ~210-220C)?

Do any sensors wear?

Anything else I am missing? What are common things to look for on a monthly basis?

RE: Preventative Maintenance Schedule

How often to check for bed leveling?

I have not checked it in 3 years.  It pretty much checks itself.  

Are there fasteners prone to loosening?

I check the terminals once a month on the power source.  I check the other screws every 2-3 months.  They rarely loosen.  

How often should the nozzle and heat brake be replaced (using PLA ~210-220C)?

Unless I print abrasives, they last up to a year (or more).  I have never replaced a heartbreak.  

Do any sensors wear?

Thermistors will need replaced sometimes.  I have had to replace them about one a year or so but I have some that are 3 years old.  I clean the bed one to two times a week.  

Anything else I am missing? What are common things to look for on a monthly basis? 

Once every 1-3 months, I add a little lubrication to the bearings if it seems like it needs it.  It increases with age.

RE: Preventative Maintenance Schedule
  • Lubricate the smooth rods in shorter intervals, but with very little amount of grease
  • DO NOT lubricate the thread of the Z-axis, as the nut is made of a self-lubricating polymer
  • Lubricate the Bondtech gears with very little grease (not the groove for the filament)
     
  • Clean the blades of the fans from dust and stringing (if you print PETG). Block the rotation of the fan if you use a vacuum cleaner, so that it does not spin with 100000 RPM 😉

RE: Preventative Maintenance Schedule

I have a google sheets I use as a reminder.  Here it is, I can add a link to it if you would like.  The cells change color based of of how late or early you were to doing the maintenance.
