Do you know what this option is for in the menu?

I cannot find any information on this parameter

Hi Francois, the disable button will disengage the motors if they are engaged. This will allow you to move the carriage or print bed by hand. You can also change the filament by hand if the printer is preheated. Pressing the button will also change the text to "Enable" and that button will engage the motors. Hope this answers your question!

This button also helps us when we are in production to check to ensure that the pulleys are set tight and that there is no slop in the motion gantry. Since it locks the motors, any loose pulleys will move if that is the case. It's something that you can use as well for that if you ever suspect any issue with backlash.

With many player-created levels, geometry dash not only tests players' reflexes but also stimulates their creativity.
