Hi everyone. I'm new here but I have my first issue using my CNC. I have a well built DIY CNC router with A raspberry PI , BCNC and an Arduino to run everything. The machine has limit switches on XYZ. When I first got the machine it homed and jogged with no issues. I've not touched it for some time and now it won't home or jog at all. When I tell it to go home it comes up with various errors. As I'm very much new to all this explaining isn't so simple but I'll try. Press Home. Error Jog. Error Both the same issues the machine goes in to alarm mode and stops the sequences. It looks as though it thinks it's going beyond the limits. The first thing I noticed after homing it is it went in the wrong direction instead of top right it went bottom left where there aren't any limit switches. It's as though the area it thinks it's in as moved out of position. As I said before I'd not touched it for a while it was fine but now it's not. Hopefully someone can point me in the right direction to fix this issue so I can start using and enjoying my machine. Thanks in advance.
