# Sovol SV06 sensorless homing is not functional

(Asked by: username_0 on 2023-04-01)

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`
