NanoDLP update...on RPi

Is there a helper script or something that does the nano shutdown and restart after an update?

I like keeping my printer up-to-date but for some time now beta updates (and release updates too) do not actually seem to restart nanoDLP.

I am wondering if maybe some file that is not installed with the normal updates got corrupted.

I don't want to do a full reinstall and I can easily work around this by manually restarting (I actually do a shutdown and powercycle)
but it would be nice to just be able to do an update and refresh my browser and get the newest version.

Of course this is only a problem since the updates come so regularly (which is great)

I usually update my Linux remote slicer box, which I wrote a script for, first.  Then if it shows a new version I automactically update the printer
installation, shutdown and reboot.

Thanks

Re: NanoDLP update...on RPi

Issue is that pigpio does not get terminate correctly (as I remember) and stall restart/shutdown attempts. (It is only important for direct control)
On the latest build I have moved to official rasbian build maybe official one does not have such issue.

Follow up:  REstart (had to power down) fixed the issue and I can now get the update to install....still have to manually restart after update is downloaded.

Follow up #2:  just clicking restart does shut down the 'printer' but it never comes back up....power cycle seems the only way to get it going after the update.

Re: NanoDLP update...on RPi

Have you tried removing pigpio? (If you are not using PWM shutter it is pretty safe to remove)

Re: NanoDLP update...on RPi

I don't know how to do that....sorry my Pi skills are under-developed...just linux transferred....is that some sort of driver or something?

Okay I read up on the pigpio library....I will look into disabling or remove it....

I should mention my rPi started out as a Phrozen shuffle pi with custom nano I overloaded the nano install via forced update,
so I am not sure removal is safe as I don't know what is direct driven vs arduino but that is what backups are for,

Re: NanoDLP update...on RPi

type which pigpiod and remove file and restart. You can take backup in case of issue to restore it. I doubt it being used on LCD printers at all
