Printer timing out.."Killed" on LCD

[DLS3141]

I'm not 100% sure what's going on. I have a Rostock Max V1 with a few mechanical upgrades. I recently re-flashed the firmware as well after changing a few parameters. Anyway, now I notice that my printer "Kills" itself (LCD displays "KILLED" instead of "ROSTOCK MAX OK") if it's left idle for a certain amount of time. I can see how this would be a feature by not letting the thing sit there for long periods while powered up. It's problematic if I'm not moving the hot end around and simply preheating the bed (yes, the bed is still on 12V and takes a while to get to 90C).

Is there a way to extend this delay so that the bed heats up completely and begins to print before the printer kills itself?

If not, is there a way to shut this off totally?

Firmware is v0.91s

Thanks

find the MAX_Inactive_time parameter, and play with that, then reload. I'm fairly certain that's what's doing it. Otherwise, just twiddling the knob does work too, or queuing a print job.

That worked, thank you
