An emulator? as in something that accepts the G-Code and runs it?

(I asked because I have one that can do that, but it is unreleased. I've considered releasing it; perhaps now is a good time)/

@user77232, I don need that it execute gcode right now, I just want that Octoprint detects it as a printer, to work with the API, read sensors etc etc etc....

Reading sensors requires executing g-code; octoprint communicates via printers with g-code. The emulator would need to be able to understand and "execute" g-code that octoprint sends to it.

@user77232, yes you are right sorry I was thinking on gcode only for tool move and print, but you are right all the communication is made with gcode

it's just serial communication, so you can make simple mockups with a PC or an MCU like arduino.

Hello everyone I'm developing a system to remotely manage several printers at the same time, using the OctoPrint API.

I would like to know if there is any way to emulate printers to do the tests, because I only have one printer and I would need several, even if they were virtual.

I tried [simrerap](https://github.com/buserror/simreprap) but it seems to be too old, and didn't work.
