    Hi, working with my new Lead Machine 1010 and decided to try GrblPanel software, as aa machinist for 25 years the Openbuilds software seemed too basic, and i wasnt able to set a machine home.

    My question is.....in GrblPanel everything seems to runs good so far, but when I run a homing cycle it homes to the front left aas it should for this machine. However the Machine coordinates are set at -700,-650,-5 (not exact numbers, but close) How do I change the GRBL settings to make the home position reset the Machine to 0,0,0

    Thank you for ant help with this

    By my understanding, grbl will define machine home such that the entire work area is in negative space and machine zero is top back right, irrespective of where the limit switches are (only the direction of these is set by $23, nothing else). It pulls the required values from $120/131/132 Max Travel settings (which I assume either you set at some point, or were pre-set for the machine).

    To change this requires re-compiling grbl with HOMING_FORCE_ORIGIN uncommented/enabled, I believe. If you send in your serial interface "$I", "View Build Info", it should send back not only grbl version and build date and a controller ID if you've set one, but also a option block [OPT: ] where the build options are given. You want there to be a Z in there, but right now there shouldn't be. Check those here: gnea/grbl (scroll down to "Queried Feedback Messages").

    For compiling, read here: gnea/grbl - there are a variety of compile-time options available to advanced users in the config.h file.

    Thank you, sounds more complicated then i want to deal with just yet. Its only for my mental peace of mind anyway, not necessary for the machine to function properly. I will wait till i have more experiance with grbl
