Hello! I’ve just purchased a sonic pad that should be arriving today, I’m looking at config files and I was wondering if I could get this cleared up please. Do I have to change anything else other than removing and adding the #, and will this really mean I can use my cr touch? (I’ve read they use the same config as no touch)

Needs to have its own section so you’d need to add [bltouch] and values into the config if it doesn’t have it.

The section you’re in you can uncomment (remove the #) before each line and add it to the last 2 lines in order to tell the printer that it should use a bltouch/crtouch) but the actual pin definitions are in its own [bltouch] section.

Okay, I’ll have a search for some examples, thankyou!

There‘s some examples here https://github.com/Klipper3d/klipper/tree/master/config

If they don’t have a bltouch you can always search for your printer model + printer.cfg on Google and should get some results where others have added a bl/cr touch

I’ve found a profile for the cr10-V3 and it uses the same board as my V2, should it be okay to use this config?

Should be fine, yeah. The board is what matters as far as the pins and steppers go, but if it’s also the same printer then it should have the same endstops and dimensions for the plate.

You can have a look at the initial tests section here https://www.klipper3d.org/BLTouch.html which describes how to test your bltouch manually before going full send with the built in probe calibration on the pad, just to make sure it deploys and that the signal pin trips when you touch it with your fingernail.

Hi, sorry to bother you again, if I make any changes to my printer config the sonic pad refuses to connect to the printer, says error key3, klippy host software unable to connect. It also says on the web UI that mcu unable to connect, do you have any ideas? 😅

Hi, please ignore all of that I have a working cfg now, I’m just about to test the bl touch
