Auto-Start Printing after crash?

Hi Shahin, i've started printing again some time ago smile

Maybe you remember my random crashes while using python syscalls. It seems they have gotten worse since i've updated.
I know it's probably not a bug because it's outside of NanoDLPs stuff. Anyways, would there be a possibility to include an option to start printing immediately after startup if there's a plate that's not finished?

I would simply run NanoDLP using supervisor which could restart the process and printing could continue.
Normally, when I notice a crash and restart the printer within an hour before pigment concentration or warping sets in, the crash is not noticeable on the prints. When it happens on an overnight print, that's not really possible manually.

Let me know what you think.

Here's the last error for reference:

Re: Auto-Start Printing after crash?

If your supervisor call /printer/resume url it could resume the last print.
