(SOLVED)Rasp Pi 3b+ not detecting ratos.local host ???
I loaded everything on Pi's card and did the first config and detected ratos.local fine...now I finished wiring everything to BTT SKR Pro 1.2 motherboard and when I start it again to upload firmware to MB I can't access local host anymore, BL-Touch does funny things when I turn on the printer....any ideas of what I'm doing wrong? Thanks

That is not normal

I'll unplug BL-Touch first of all and see then...need to find out where the problem comes from...I'll also check my router access in case is not allowing access from Pi anymore. But clueless at what's wrong.
What's the vminion local host access like in words? is it http://ratos.hostname/ ???
Or do I type Vminions IP address? because I can access it by IP but not through ratos.local etc
Don't rely on ratos.local. it doesn't work in a lot of cases. Use the IP address and set it as static in your router

Thanks, just found out the hard way....
Do I update first or load printer.cnf ???

Need help, completely lost as to what to try next…can’t connect to printer anymore…😢

Started all process again, everything is fine until I try to load printer.cnf , then it stops working.
Do I need to change printer.cnf if using diferent motors ? I'm using these ones... https://es.aliexpress.com/item/32704584112.html?spm=a2g0o.order_list.order_list_main.777.6135194d21Bs7E&gatewayAdapt=glo2esp
You need to edit your printer.cfg to match your setup.

Never done it before, any idea on where to find info on how to do it?....I thought this would be easier....I'm lost in the forest...anyway, thanks
Follow the instructions
https://os.ratrig.com/docs/configuration
Now navigate to the Machine page in Mainsail (the webinterface you just opened in your browser), there's a list of files, among them is printer.cfg. Right click it and choose "Edit". This is where your klipper configuration lives. As you can see, it's prepopulated with all you need to get your printer up and running quick and easy. Follow the instructions in the file to make sure the configuration matches your setup.
Configuring RatOS | RatOS
RatOS only needs minimal configuration to work, but comes with a lot of optional functionality that you can enable manually.
You might want to re-read the documentation on ratos since it details all the important things you need to know. Remember, ratos is just prepackaged klipper and mainsail with nice configurations

Thanks m8, I'm confused as to wether I need to change motor names in .cnf, that's the only thing is different from RatRig's standard...had them laying around at home. Everything loads fine until .cnf file, then it stops working and there's no way I can connect to Pi anymore, have done unplugging every element, as per your guide with no success, it is really frustrating when you don't know what to look for and when you're a complete newbie to compiling and modding things.
What URL are you using to connect to the pi? You should use the IP address as ratos.local doesn't always work. I set my router so that it always gives my pi the same address (static IP address)
Even if you have your printer.cfg wrong, you should still be able to connect to the pi

I’m using static ip for the printer and access through ip address, works well until I load printer.cfg…I’ll change the usb cable in case it’s faulty for some reason and do all the process over again. Once done I’ll get back here with results. But would like to know if I need to change printer.cfg file for my motors, and what exactly to change if so before trying to load printer.cfg file again….
I do not know what specifically you will need to change with your different motors. You will need to look at the documentation for your motors and the klipper documentation on the stepper drivers you are using (like 2209 for example)

Will read documentation and see, but first will change usb cable in case it’s faulty. Thanks for your assistance 👍
Your info so far has been very useful thanks !!! Lots to read, understand, test and adjust !!!
Finishing testing and configuration on printer.cfg file for my set up....get this error and can't figure out what offset is meant to be....thanks Quote "Option 'z_offset' in section 'bltouch' must be specified
Once the underlying issue is corrected, use the "RESTART"
command to reload the config and restart the host software.
Printer is halted"
Option 'z_offset' in section 'bltouch' must be specifiedhttps://www.klipper3d.org/Config_Reference.html#bltouch so in your printer.cfg there should be an area that you un-comment and fill in the z_offset
https://www.klipper3d.org/Probe_Calibrate.html#calibrating-probe-z-offset is how you find that z offset

Finally got it working, it looks like it was a faulty usb cable. That said I’m having X and Y moving right but Z won’t the job…will check if stepper driver is burnt or a faulty wire connection as I’m getting the machine ready for easy dividing the electronics box and the printer itself. Will report back and post progress just in case this can help others while building their VMinion. Printer.cfg file had to be edited to suit my needs, looks like a quite intuitive thing so far….intimidating though when your new to it, but world is for the brave and ignorant 😂😂😂
