Make sure, that the printer is cooled down!
⬢If not, go to Control > Temperature > Cooldown. Wait for the printer to cool down.
⬢Auto home the printer. Go to Control > Auto home. And wait for the printer. Do not touch the printer. 
⬢Disable the motors. Go to Control > Disable Motors. Now we can move freely with XY-Axis.
When the motors are switched off, the heatbed moves downwards to prevent the nozzle from being scratched.
Cover the heatbed with a piece of cardboard or a towel to prevent it from becoming greasy.

Step 4 CAUTION: Lubricant Handling

⬢Each linear bearing rail has a small hole for lubrication. Look at the picture.
⬢On the right X-axis rail:
⬢Insert the needle and squeeze the cartridge. Squeeze out exactly 0.1ml Microlube.
⬢On the left X-axis rail:
⬢Insert the needle and squeeze the cartridge. Squeeze out exactly 0.1ml Microlube.
