Is there an alternative to Putty for Mac users?

On MacOS you can just open a terminal. from the terminal, you can directly use ssh.

ssh pi@ipaddress
for instance: ssh [email protected] if your prusalink has 192.168.0.100 as IP address

RE: 0.5.2 Documentation missing for USB and non Zero Pi

I have a pi 3b+ connected to a buck converter for power, can I connect via GPIO ?

RE: 0.5.2 Documentation missing for USB and non Zero Pi

oops nevermind i forgot to enable RPi Port in the menu (facepalm)

RE: 0.5.2 Documentation missing for USB and non Zero Pi

Thanks for pointing that out, also

CTRL + SHIFT + X to get into advanced options in the Pi Imager, there's no button or menu item which is weird.

Yes, you will need to use the Raspberry Pi Imager software advanced settings to allow for SSH.

hey.

i cant connect via SSH. is there any option you need to activate on the sd card before using SSH?

Error Message: "Network Error: Connection refused"

Might need a sudo or two in there for mkdir and touch.

Can you elaborate on "a sudo or two", I'm not the best with programming so I'm not sure how to do this.

sudo touch prusa-link.inipi@prusa:/etc

 sudo nano prusa-link.ini         Not programming, *nix privilege escalation 🙂

RE: 0.5.2 Documentation missing for USB and non Zero Pi

Nice.  One of us really needs to do a quick and dirty dead nuts correct document for USB connect.

RE:

Folks  - This applies to release 0.6.0 also. Note: When installing Prusa-Link on your SD card, make sure you check the box to enable SSH and set a password. Rest of the instructions  for RPI3/4 can be found in this related post on the forum:

https://forum.prusa3d.com/forum/introcuctions-instrutctions/raspberry-pi4/#post-552325

A neat trick for the Pi is to put a file called "ssh" on the boot partition of the SD. That turns on SSH (and the file gets deleted)

RE: 0.5.2 Documentation missing for USB and non Zero Pi

just thought i'd take a crack at it but no dice for me. Prusalink 0.6.0

trying prusalink.local tells me firmware is not up to date. was forced to update from 3.10.0 to 3.10.1 still nothing. 

i tried using the local IP assigned nothing. im not sure if its my ip, because when i boot the pi image with a monitor, i see that it has been assigned an ip address. 

RE:

Are you able to see the printer as a USB device on the raspberry pi? e.g.

$ lsusb -v

Are you able to connect to the printer ok with the same USB cable on a computer? Try connecting the cable to a different USB port of the Raspberry Pi.

i was able to update my Mk3s+ firmware using same cable.

RE: 0.5.2 Documentation missing for USB and non Zero Pi

I expect you have created the config file specifying the port /dev/ttyACM0 like OP explained, if yes, then the only option I can think of is to go through the logs looking for the port it's using and  what's it unhappy about.

The log is at /var/log/daemon.log, there might not be enough detail there, but we'll deal with that once we get to it

RE: 0.5.2 Documentation missing for USB and non Zero Pi

Yes i have 

[printer]

port=/dev/ttyACM0

baudrate=115200

Will check logs asap.

RE: 0.5.2 Documentation missing for USB and non Zero Pi

NOW im getting somewhere.. i decided to redo everything and i am now at Prusa Connect Settings. 

i get a "Can't resolve Prusa Connect hostname." error with hostname = connect.prusa3d.com

i have the port at default = 0

RE: 0.5.2 Documentation missing for USB and non Zero Pi

What are you currently using to connect to the webGUI? The hostname or IP address of the Pi?

I know that the default port is 0 (e.g. 8080) once the system is configured. Did you also happen by chance to change any additional settings when configuring the PrusaLink using the RasPi Imager? (Change the default user from “pi”?) which may cause the setup to stop working.

I would personally also try to restart the setup process again with an incognito/private browser window… as I found that useful features such as Autofill mess up the configuration process. 

RE: 0.5.2 Documentation missing for USB and non Zero Pi

looks like i got it setup. 

i was connecting with Prusalink.local. when i tried connecting with my local ip address, voila! now to figure out how this thing works. im now looking into how to send a file to print. 

thank you very much.

RE:

The fact that your MK3 reboots when you boot the pi does sound promising.

Yes and the Pi also stops, without shutdown process, when you turn the printer off.

RE: 0.5.2 Documentation missing for USB and non Zero Pi

Yup, it's same as octoprint on zero and yes, I'd like to make it a little smarter too

RE: 0.5.2 Documentation missing for USB and non Zero Pi

All the more reason to connect via usb.  For just the cost of a usb data cable, and a usb power supply, which may already exist in your pile of electronic leftovers. And, no soldering of headers, after, of course finding the right headers, and trimming off the interfering pins. 

Puzzling to me that we have plans to hard mount a $10 32 bit computer which is more powerful than the recipient. USB was created by smart people, to solve problems like this.
