# Extra data appended to the Y values when issuing M92 & M500

I am still trying to dial in my Anet A8.

The Marlin firmware takes too long to scroll through the axis settings when I change them, so I use Repetier Host instead issuing M92 followed by M500.

I noticed in the log window that X goes in as typed but that Y has a *75 after the value i input. Can anybody tell me why/what it is for? I suspect I know what it does just no idea why it is doing it.

*75 is the checksum value, (a method for verifying the integrity of the transmitted information).
