I can cold start the heck out of this machine, jog it about, etc...i just cannot figure out the fixture / tool length offsets.
I've tried for about 6 hours total on two different days. with every method i read about. and I've read 5 threads here and elsewhere about modes 1, 2 E1. G54 etc....
I'm in mode 2 btw,
It just wants to stuff my tool well below the part surface, or ignore my offsets completely it,s nowhere close. luckily I am starting well off to the side of the part so I haven't crashed anything.. I have to slide hold and return it each time.
My tool length method is adapted from the way I grew accustomed from my old mill, maybe it's totally wrong for this machine? here it is:
I have one "master tool/edge finder" I'm accustomed to measuring and entering all my other tools relative to it. it's about 2" from spindle face to tip so most of my tools are an inch or so longer than it. I use a height gage and a block as a presetter. My tools all have various +Z entries in the the table.
actually I've tried - and + values.
After cold starting the machine I jog to the part surface with my "T1 Master Tool" in spindle and I look at the z height and remember it, then I go to the space menu for offsets and enter the Z height (say -9.000 ish to get down to my part top in vise with master tool) in the fixture offsets #1 I'll put in Z=-9
my most recent code looks like this: (WITH MY COMMENTS ADDED HERE IN PARENTHESES)

please.
