    I use OctoPrint (OctoPi image) on Raspberry Pi for both my printers.  One of them doesn’t have a UPS, and a recent brief power blip has caused it to die.  I haven’t picked it apart but I’m pretty sure it’s a corrupt SD card, which seems to happen about 100% of the time when it suddenly loses power.  So I need to re-flash the SD card to get it back up and working.

    This is annoying and a few months ago I had dabbled with setting up a read-only filesystem so the SD card can’t get corrupted on a sudden loss of power.

    I guess I am looking for advice for the longer term, which might span both printing and milling use-cases.

    1. Find an image that has read-only mode?
    2. Start with a base image, e.g. V1 Pi, and figure out how to implement read-only mode?
    3. Buy more UPSes?
    4. Other options?  Network boot?

    There is a huge amount of discussion around power management for the Raspberry Pi, and I haven’t but scratched the surface, but so far nothing is standing out as the obvious killer solution.

    The custom pios is pretty slick if you wanted to try making your own image. I am not sure the best way to make it read only. It might best to configure everything and then just change it to mount ro after you’ve got it set up. Maybe with a button on the landing page?

    Another thing you can do is to put your configuration and files on a usb stick and then just get a bew sd when it fails. I do this on my printers, but since I did that I haven’t had any failures either…

    Dropping in to say thanks. I finished setting up v1pi early this morning. I haven’t tried cnc.js yet but octoprint is working as intended and after installing the desktop environment on the pi, I’ve got everything I need right next to the machine. It’s good work – thanks for your effort.

    Have it running for some time now, with both the MP3DP & the MPCNC.

    So I just ordered a new Raspberry to connect both machines instead switching between the garage and the living room.

    So the first Raspberry I connect now with 192.168.178.50 , with the second one I guess I have to change that address somewhere ?

    If it’s connecting to your home router, then it will get a different ip automatically. The trouble is they will have the same hostname (v1pi). There are many ways to change it, but I think there is a choice in the raspiconfig. I usually just change it in /etc/hostname and /etc/hosts. If that makes your eyes cross then just use raspiconfig.

    Yep, just worked fine. Renamed my old Pi 2, at least that’s what I think it is, and this morning received a Pi 3 A+, don’t need the Eth, or additional USB’s. Pricewise it was just 1-2 $ above the Zero WH, so it was the smarter choice.

    Thank you so much, I am kind of doing something similar, but mine does have little different approach and what I am wanting to do is, to make it launch a UGS app right at the beginning once the pi boots (entering kiosk mode) and from there you can yous pic the code that you want to send.

     

    Even thou I do not seem to find a good spot where to install the pi (I was really looking forward to place it in a case that way there is not that much trouble due to the wiring and also was considering to even remove the screen that comes in default in the kit, since I will be using the pi I don’t think that there is need for that other screen), since that is what I am looking to be able to do

    That’s totally possible. The v1pi is shooting to be a headless server, so no screen and no guis running, which will make it work even on a pi zero w.

    The custompios that I use is pretty slick and it’s a great place to start.

    Since where is my workshop the internet connection is not the most stable so, I am aiming for something that I can be able to use more accurately, and well I think that I can be more accurate when setting a homing point, rather than twisting the nob that way even my parents will make it

    i cant get it to control my lowerider and the service crashes right after just a few sec using cncj 1.9.20 connecting using Marlin (tryed all of them) and every baud rate switched over to the octaprint and it worked fine first try. Any advice Ty

    Ok got it to connect but after trying to jog Z just one side gos up (seems like feed rate to high) i go into machine settings set the feed rate of z to 8.5 and then in bottom right select the profile and still no change is there some other way you have to change feed rate?
