How to Update Prusa Firmware

Updating software and applications is not exactly new to us; information technology’s something nosotros do regularly on our smartphones for better operation. Usually, Google Play store for Android and Apple shop for iOS is how we carry out updates.

A Prusa 3D printer has neither of these online stores. So how then practise we update the Prusa firmware? Past the time yous’re done reading this article, you should be able to update Prusa firmware with ease.

Prusa Enquiry updates numerous things, including firmware on a regular basis. The latter includes enhancements to the printer’southward operation, such as new features and correcting problems from users’ feedback.
