    ...any Doors fans? lol.

    Anyways, I had a question about the end of the cnc milling job on the Lead 1010. For some reason at the end of the job the router moves up the Z axis OK and turns off, but continues to the back RH corner of the 1010 and runs hard into the end (there is no limit switch on the rear of the x rails and no limit switch on the RH side of the Y axis).

    I'm sure its a simple setting, but can i get the machine to return to 0,0,0 (or some other safe location) and turn off the router and vacuum at the end of the job safely? ie. without me being present.

    I'm using Fusion360 with the OB Post processor, and the OB black box with the CNC interface.

    ...side question, I just saw a new blackbox x32, is that a worthwhile upgrade from the original blackbox? the latter seems to be working just fine for what i've been doing...so far its only been user errors / learning curve. lo.

    You have two options, which are both in the post processor settings.

    Currently you have it set to use G53 at the end of the job and have specified X0Y0 (which is the default, I believe). G53 X0Y0 is the back far right of the machine. You can change that to another location, but be sure to use negative coordinates so you dont break on through to the other side.

    Or you can change it to use G54. G54 X0Y0 will be your stock X0Y0. It will still use G53 for the Z movement.

    this action means you have changed soem of the postprocessor settings from the defaults.
    The default is to raise Z to just below the limit switch and return X and Y to the job 0,0.

    Each option has some help attached, just hover your mouse over the setting to the see the help.
    Basically, if you have homing on then the number sfor X Y and Z end position MUST BE NEGATIVE and in millimeters. The defaults are -10mm.

    Thanks guys! So the following is what the default was for me. Should I just 'uncheck' the G53 check box?

    yes uncheck it, and colored blue is NOT the default, that indicates a change.
