Gcode scheme to repeat prints?

Do people have any tips on doing repeated printing, where the printer ejects a part after printing it and prints another, on and on? The gcode to push the print off is simple, but how can I restart the print at that point?

My motivation is printing protective face shields for health care workers: I can print a shield in about an hour, but then I need to remove it and restart it. If I do one at a time and orient it right, I might be able to break the seal with the bed and push it off. Maybe I'll hit it a few times, maybe I'll let it cool X number of minutes... I don't know. But a simple way to get it to restart would save some headaches.

Thanks!!

RE: Gcode scheme to repeat prints?

Rep-rap has the m41 command. I have not been able to get it to work with my prusa. Is this disabled?

M41

If the RepRap machine was building a file from its own memory such as a local SD card (as opposed to a file being transmitted to it from a host computer) this goes back to the beginning of the file and runs it again. So, for example, if your RepRap is capable of ejecting parts from its build bed then you can set it printing in a loop and it will run and run. Use with caution - the only things that will stop it are:

  1. When you press the reset button,
  2. When the build material runs out (if your RepRap is set up to detect this), and
  3. When there's an error (such as a heater failure).

@sembazuru

It seems like now is the time for continuous printing 🙂

I've abandoned the auto-repeat approach. I got ejecting to work fine with PLA, and just copied and pasted the gcode over and over in one file: works well!

I'm focusing now on getting a stacked design that separates in PETG when printed with 250um layers: there's no way I can break the build plate bond by pushing with the carriage.
