Ender 2 Pro CRTouch configuration, with a little discussion on the installation.

This is just a short clip talking about adding CRTouch to Ender 2 S1 pro, with included config example needed to get the prob operating and add ben mesh and other menu items missing. I also added the manual bed screw settings to get that via menu system as well. I found that for most people when you are new to 3d printing like myself you find that these “Ender CR touch. BL Touch videos seem to focus on the hardware install, then they say “Now configure it” but never tell you what to configure, and if you google Ender 2 Pro CRTouch good luck finding this configuration information.
If this video was useful to you please hit that like button and leave me a comment, question, critique etc. I am glad we have this resource to share information.
My example printer.cfg you can use it as a guide and although you may have a Ender 2 Pro make sure you test anything before running it for real. Use my settings at your own risk. Items commented are the important settings these will enable the CRTouch to work, and provide you with menu options in KlipperScreen for bed mesh, Z-offset(if not present), manual leveling via screws in menu. (note you can delete the comments from the values i.e. "// blah blah blah"

where can i find sensor pin and control pin for 2.4.s4 board? i've recently switched to klipper and just bought a bl touch

[@escuvideo]

any succes?

[@banner5432112345]

Motheboard 4.2.3 ? Or 2.4s4

[@tactikool4740]

Sorry if I missed it but this is done with klipper correct? Not Marlin?

[@TomHansen74]

Hi. would you mind sharing your printer.cfg with me?, I would like to convert to klipper on my ender 2 pro with CR touch.

[@Si3D]

Hi, you did a beautiful job I am oer to install klipper on my ender 2 pro too, can you send me your updated.cfg file I may need it very much thanks
