    Hey All,
    Been searching the web for several hours, and I am ready to ask for help. I have just completed my 4th build, and this one was very straight forward. The build consists of the following; ACRO bundle, X-pro v3, Grbl 0.9, & UGCS 1.0.9, nothing too exotic. However I am now fine tuning the system, which includes trying to get the homing function to work, and I need to eliminate the Z-home first function (no Z required for the laser).

    I have tracked the home sequence commands down to a certain two lines in the grbl-master config.h file. My problem is,how do I access that file in GRBL for editing (arduino ide??). After that I assume it should be a straight forward firmware download to the X-pro?

    Thanks in advance

    You are correct... use Arduino Ide or edit in your favourite editor like notepad++ and resave it. I would suggest though that you update GRBL 0.9 to 1.1F unless you specifically need something in 0.9 or your program doesnt work in 0.9.
    I also run a laser with no Z axis and removed the unnecessary code for homing the Z axis (the Z axis gets homed first and the machine with Alarm eventually when it doesnt reach home first.)

    Thanks Russ, That symptom is exactly what I was seeing. I will give it a shot tonight when I get back in front of the machine.

    Had to do the same thing... comment out the z homing portion. Also need to tell it that its ONLY 2 axis!

    Wow, no sweat at all, it went smooth. Edited the config.h in txt, saved as HEX (arduino), then uploaded with X-loader. Now I just have to figure out how to make the Y home in the neg direction (x-homes in neg) while still keeping the UGCS keys function properly. Always one more step to go. Thanks for the help Russ.

    Should be able to make homing neg in the $23 with the proper entry from the table below...

    Setting Value Mask Invert X Invert Y Invert Z
    0 00000000 N N N
    1 00000001 Y N N
    2 00000010 N Y N
    3 00000011 Y Y N
    4 00000100 N N Y
    5 00000101 Y N Y
    6 00000110 N Y Y
