I need help with my creality ender 3 v2

Hello everyone my name is Tyler I am new to printing. Just bought a second hand ender 3 v2 with upgraded sprite extruder and had problems with getting the bed plate level so I went and bought a cr touch thinking it would solve my problems little did I know I had to take printer apart to install aswell as reinstall firmware. I’m absolutely stumped everything is printing squishy lol and I had to move print bed ahead 1/4" to make the cr touch work lol I’m aware i need to adjust offsets now but the thing I can’t wrap my head around is adjusting G code in the slicer from g28 to g29 also what needs to be adjusted for the upgraded sprite extruder and where would I find the software for v4.3.1 board I cannot find it on the creality website

Update! In case anyone is having the same issue. Here is the link that has saved my night after hours of ripping my hair out :joy:

You do need to set the offset distance between the CRTouch and the nozzle tip, in the Z and Y axis’s, so it knows where it is suppose to be.

Just add the G29 code to your slicer machine settings (in Cura, may be different in other slicers) right after the G28 command in the “start G code”. This will start each print with a scan of the bed so it knows how level the bed is. Not absolutely necessary but it only tale a minute or so and gives good results.

Can’t help with the sprite extruder, not familiar with it.
