I'm having trouble with the definition of homing parameters. I understand HOME_SEARCH_VEL Move say left until the N/C Home/Limit switch opens. HOME_LATCH_VEL going in the other direction to the right back off the switch once it's been found. Done much slower so the Machine Axis Home position is repeatable.
Now it gets a bit vague. (using inches) HOME is set to 0 by default. If I set it to +0.05" for example, then it's 0.05" to the right of the physical home switch. (That's a quarter turn of the lead screw handle) That means HOME_FINAL_VEL is then used to go to that position? It doesn't need to be signed because the system knows which way to go to the HOME setting? So ideally, since my Home/limit are one and the same I should set it a tad to the right so that a move to Machine Home Position doesn't trip the limit? Or does setting HOME_OFFSET to -0.05" do the same thing? And if I set HOME_OFFSET to -0.05" then after the HOME_LATCH_VEL move to see the N/C switch close again it continues to move 0.05" at HOME_FINAL_VEL to reach what it now calls 0.000"? Have I got that right?
