I just unboxed my Sovol SV06, and it does not appear to home correctly. When issuing the G28 command through both the screen and Pronterface, it will crash against the X-axis limit switch until I turn off the machine, as shown in the video below.

I have attempted to use Pronterface to issue new M914 commands, which is the StallGuard sensitivity setting. I have lowered both the X and Y values to 10, sent the M500 command, verified the settings were correct with M503, and then ran G28. The same thing occurred and it does not appear to function any differently.

I have verified that all of the steppers are plugged in, but I have limited functionality to test anything because the machine cannot home correctly. Is there something I am missing? Included below are the results of running M503

It turns out that the previous post I had found suggested that the sensitivity setting be lowered when it actually needed to be raised. Setting the two M914 values to 75 works perfectly.
