Short answer
Prusa says the MINI and MINI+ have four PTFE tubes (two external, two internal) to replace when deformed or worn, smooth rods to clean after about 200 printing hours, and no lubricant on the Z-axis trapezoid nut or lead screw. They take E3D V6-type nozzles. Prusa added input shaper with firmware 5.1.0, but lists the MINI and MINI+ as not compatible with its Accelerometer Set.

- Four PTFE tubes (two external, two internal), replaced when deformed or worn; clean the smooth rods after about 200 printing hours; no lubricant on the Z-axis trapezoid nut or lead screw[4]Prusa says to clean the tubes with compressed air, not a solid wire, which can damage them inside. It allows the supplied Prusa lubricant or a good super lube on the X, Y and Z smooth rods, and says to check fans every couple hundred hours.

Watch out for
- There are four PTFE tubes, not one: two external and two internal. Do not push a solid wire through them; Prusa says compressed air.
- Never lubricate the MINI+ Z-axis trapezoid nut or lead screw, per Prusa.
- Prusa lists the MINI and MINI+ as not compatible with its official Accelerometer Set, even though input shaper arrived with firmware 5.1.0.
- Prusa says crash detection is not compatible with input shaper.

Questions
How many PTFE tubes does the Prusa MINI+ have?
Four: two external and two internal, per Prusa. Replace any tube that is deformed or worn, and clean them with compressed air rather than a solid wire.[4]
Does the Prusa Accelerometer Set work on the MINI+?
No. Prusa's product page lists the MINI and MINI+ as not compatible with its official Accelerometer Set. Prusa added input shaper to the MINI/MINI+ with firmware 5.1.0.[6][3]
How often should I clean the MINI+ rods?
Prusa says to clean the smooth rods after about 200 hours of printing, and not to lubricate the Z-axis trapezoid nut or lead screw. See the maintenance schedule.[4]
