Re: OctoPrint issues and tips

Feb 07, 2018 6:59 pm

Hi,
I just installed Octoprint (The Prusa version) on a RPi Zero and would like to connect it to my MK3.

Some questions:
1) Is there any functionality/performance/reliability difference between connecting thru USB or the Serial pins?
I know that USB requires an external Power Supply and the 2 GPIO (Power loss? and filament detection?) won't be available but for just remote monitoring doesn't seems a big difference.

2) Kind of same question between printing from SD card or directly from Octoprint. Any functionality/performance/reliability difference?

3) Did some preliminary tests with a camera connected to RPi Z and the system seems to crawl... Any one using a RPI1/2/3/3B/etc?

Thanks!
Jose

i have the pi0w running. and it works perfect. (new FW and the new prusa iso).
No Problems at all. (ok took a while to find out that the rpi don't support chanel 12/13 Wlan :roll: because it did not connect to router..)

now i would like to connect a logitech 720 Webcam. did anyone try this?

I printed the case with the door for rpi. but there ist litte to no space to get a usb plug in there.
what cable and plugs did you use?

I think i would solder a smal micro usb plug to the webcam, but i haven't found a cable with a smal plug yet.

After upgrading to the latest firmware I was able to successfully monitor and print from Pi3B using the USB. I decided to make another attempt to run my Pi3B to the accessory port on the back of the Einsey to see if the new firmware made this more reliable to the Pi3B UART0 interface. I again was able to establish an initial connection and did start an SD Print. It was about 1 min in and then it crashed just like before but maybe even sooner than before on RC5.

Below is the last report of disconnect from the serial corrupted connection. Accessory Port still seems to be unreliable.

After some hardware/software setup I'm now runing OctoPrint on Odroid XU4 and my MK3 is connected to one of the USB3.0 ports. I'm getting crashes from time to time - sometimes they end up fine but sometimes it's layer shifting (g-codes generated using unchanged Slic3r profiles - since I've just read about the changes that need to be made).
That's interesting, because I've still got an Odroid X2+ lying around and I thought of turning it into an OctoPrint server. What Linux distro are you using? I was thinking of running ArchLinux on it, as there's an OctoPrint package in their repository as well.

If you want your pi to work on WiFi Channel 13, you need to tell the Pi that you're in the UK or another country which allows Ch13 to be used. You'll need to login via terminal (either ssh or plug in a screen and use the command line) and run:

Code: Select all

sudo raspi-config
You will find the option you need under "4 - Localisation Options" then "I4 - Change WiFi Country". Once you have selected UK, select finish and reboot.

Biggest advantage, it gets its power from the EInsy board, Takes less space, is better organised. Biggest disadvantage, tbh a Pi Zero is underpowered and struggles when you want it to record video/timelapse . I have both a Pi3b and a Pi zero W, so I will test both. Runing another make of printer at the moment, and quite happy with the Pi3 based control
I'm powering my rpi3 via einsy board pins. Seems to work fine even with a rpi cam v2. my print quality from octopi seem worse than from direct sd card printing though.
