 It's a good idea to make sure your belts are properly tensioned before attempting any calibration process. I know, it's a pain in the ass, but making sure the hardware is properly calibrated first will ensure you get valid, consistant and thus usable calibration results.
 
 As I have a P1S, I'll follow these steps:&#x20;
 
 * [ ] Check belts - retension if necessary
-* [ ] Inspect carbon rods & Z-axis linear rods - _Wipe with Isopropanol every once in a while_
+* [ ] Inspect carbon rods & Z-axis linear rods - _Wipe with Isopropanol once a month_
 * [ ] Check Z-axis lubrication - _Clean & lubricate if necessary / if you see plastic debris stuck_
-* [ ] Run the 30mn calibration process.\

 ### Max Volumetric Speed

 _This allows you to find how much your printer can actually go Brrrrrrrrrrrrrrrrrrrrrrrrrrrr_

 You need to understand that setting print speed to 300mm.s won't change anything if your filament's max flowrate is set at 15mm^3.s; that's why we need to find how fast it can go before going Brrrrrrrrr.
 
 Most PLA & PETG can be printed at around 15-20mm3/s with no issues on the P1S.\
 &#xNAN;_(That being said, I've installed a CHT nozzle on mine and reached a clean 28mm3/s on most PLA)_
