Maintenance intervals for commercial printing
Hello, quick question 🙂
I need to figure out the maintenance intervals for the wear items, to properly budget for them. For the moment I am considering the following components as "wear items":
- LM8UU bearings (10 x)
- 0.4 mm OEM nozzle
Concerning the bearings, I prefer to replace them with new Misumis (+ Synco Lube) instead of regreasing the old ones. (If the machine is already apart ...) Cant really get the old grease out there so just pressing more into the crud isnt a proper solution imho.
What hour intervals would you suggest? I was estimating between 1000-1500 hr regular intervals for the bearings and nozzles. I will be printing mostly PLA at pretty conservative speeds.

If the smooth rods are regularly lubricated they may never need changing.
0.4 mm OEM nozzle
With heavy use printing PLA reckon on 6 - 9 months. It may be shorter if you print a lot of white or pastel colours, longer with clear/natural.
Cheerio,

Hello Diem,
thats good news then!
My rods are still in great condition. I ruined a pair on my first printer because I tightened the extruder bearings too much. Lesson learned, all golden so far. I might still replace the bearings once a year during general overhaul/cleanup. Careful installation and alignment does pay off here.
For the nozzle, I might budget more frequent replacements for these. Maybe every 500 hours. Just to keep great print quality as they do wear down a bit too. They are not expensive and its easy to change. Don't see a reason not to 🙂
Just recalibrate first layer 'Z' offset every 2000 hours or so and they should be good for around 6000 - 7000 hours.
Cheerio,
