Hi, I’m a beginner user creating firmware following a million instructions, and every time I encounter a problem during the bed leveling stage. Even though I’ve set the bed probe offset perfectly, during the leveling process, the extruder hits the right frame. What am I doing wrong?

What settings are you using? I can’t even get past the blue screen when I use the firmware builder for this combination.

Because the Sprite Pro has a protrusion on the left side the X-limiter switch has to be moved. I use a model from ([https://www.printables.com/model/474268-ender-3-originalprov2-x-limit-switch-bracket-for-s/files](https://www.printables.com/model/474268-ender-3-originalprov2-x-limit-switch-bracket-for-s/files)) which replaces the x-switch housing with one that moves the switch to the left. I’ve had it for a year, really does the trick.  
There was another problem with the X-carrier screws hitting the right side vertical. I just reversed the screws so the heads were at the backside of the x gantry.  
Hope this helps.
