Post Processing Question

I created a post-processing file and set up instructions for my machine from a 1911 file. I set up the cam software to work with GRBL and created a simple file to drill all the holes in a 1911 receiver.  I am quite new at this and would like to know if what I created looks correct and ready to run with my flex?

Images from setup file:

Looks generally good with a few issues;

1. It looks like your work/material origin is about 70mm above the top of the frame, which will cause your X to move out of bounds/crash on ends when handed any G0 X-60 or so. Move it back to some point of reference on the frame that is easy to measure from/zero off of. The Y and Z axes look to be in bounds though.
2. DDFW and most other GRBL installs don't contain support for full feature toolchange commands (T1, T2, etc), so you'll want to insert M0 pauses or split the file up into multiple smaller code routines to do your manual toolchanges. The toolchange commands DO change offsets and tool lengths though, and although this doesn't require extreme accuracy in drilling operations you'll want to make sure your bits are installed to within 1/8" or so of the length and offset specified in the tool file (so that the drill bits don't crash or plunge too shallow).

Looks good otherwise, though I may have missed something.
As a rule of thumb, running super slow dry runs or test pieces are always a good idea when getting started. Once you've seen a few routines run and are familiar with how your CAM/post processing and different commands work it starts to get safer to run straightaway.

Would it be possible to get a configuration file to have a starting place when using UGS software? I'm not sure what the correct values are for each axis:

I have the Default Values (below) but need the starting actual values?  Also, My unit did not come with the endstops, do I need them or can they be set with software? If so I'm not sure how? Do I need to edit the config file in the USG program?
