I have an ender 3v2 that I want to convert into a custom keychain generator.

The machine will work by taking 3d printed keychain bases from my p1s, and printing custom text onto them. It will likely only print one layer and will use a large nozzle size. It will essentially just write the text onto the keychain bases.

Instead of a print bed, it will feature a holder for the keychain base. It will not need a heated bed as the keychain base holder will hold the keychain base in place.

I want to create a piece of software that takes input text and converts it to the corresponding g-code. Has anyone got some tips for this?

And what operating system should I run the printer on? As mriscoc seems to not allow prints when the print bed is disconnected.
