I finally got out to the Green Monster today and started feeding in
soft limits, home offsets, and auto zeroes. Before setting Home
offsets, it didn't back off the limit switches. Now it is. Hurray!

I think (confirm my assumptions, please) that I'm using the upper
right quadrant in the Cartesian system for positive X and Y.
X home is left, Y home is toward me, Z home is top.
I'm working in inches with 52" X and Y ranges, & a 5" Z range.

In the Motor Home/Softlimits config box, I have
Soft Max 51.00
Soft Min 0.50
Slow Zone 1.00
Home Off. 0.50
Home Neg. Checked
Auto Zero Checked
Speed 20%

in X, Y, and A boxes (Home Neg Xed on A, which is slaved to X).

Pic, far left is home corner. http://tinyurl.com/com9z8g
Pic, I changed Y back to mirror X http://tinyurl.com/d3kdnt8
After saving, I have lost a few thou on the DROs. Curious.

OK, I click the REF all home button and Z goes up, hits the limit
switch (home) and backs off less than 1/10 turn, even though the
offset is set to half inch. Then Y comes home and backs off about
0.1" with the offset also set to half an inch. Then the gantry goes
left, hits the X1 (A axis) limit switch, stops, reverses 1/8" or so,
and then moves left again. This is where I get a limit switch error.

Questions: Why is it erroring out? Why the small movement when the
offset is listed higher in the soft limits? I had a 0.1" offset at
first and it moved the same distance back off the limit switch that it
has with the half inch offset entered there. Why? Is it only moving
until it deactivates the switch? With X and A slaved, why isn't it
locking one side and doing the other afterward?

Help, please.
