Alan,
... when I click on the arrow Set Z Zero nothing happens ....
That's not what I'm seeing - Let's walk thru an example to see where what you see differs from what I'm experiencing.
The example I'll construct can be done in sim mode - that way I don't have to worry about imperial / metric units or what the working envelope of your machine is.
1) fire up mach 3.43.22 with MSM 0.3.14 (Beta 10), get it ready (out of estop)
go to the reference page - the MSM Verizon shown is "Version 0.3.13 (Beta 10)" - correct?
Menu - help - about - mach version = "Version R3.043.022" - correct?
set up the gage block height
2) go to settings-common page.
3) set Gage/Plate Height DRO = 0.5
set up the MT params
3) I'll use T251 as the MT number for this example
4) go to the Tooling page
5) master Tool Mode options panel:
set this option combination:
TC Auto TCP OFF
Master T Mode ON
TC Auto TLO OFF
RH T-Holders OFF
Master Tool #: DRO = 251
Master PTL: 2.0
we'll get the MT mounted (so mach knows it has the MT as the current tool)
6) via MDI: T251M6
7) complete the tool change (don't actually physically mount the MT in the spindle - we will fake a Z touch off rather than actually touching the MT to a surface, no tool mounted gives us the most clearance possible while testing)
8 ) now we have T251 (The MT) mounted - which is the MT
9) Current T# DRO = 251 correct?
10) the TLO for the MT in MT mode is always = 0
The TL Offset DRO value should = +0.0 Correct?
we will set up for a touch operation in MT mode:
11) go to WC offset touch page
12) big Green MasterT Mode LED is on - correct?
13) via MDI: G53 G90 G0 X0 Y0 Z0
14) zero X, Y & Z - ok , now we have MC=WC=0 for X,Y,Z - all DROs for X,Y,Z in the offset panel should be 0
15) MDI: G53 G90 G1 F5 Z-1
16) Z row of offset panel should be:
-1.0 = -1.0 - +0.0 - +0.0 - +0.0
We are set up to do the "Set Z Zero" operation
we have:
MCZAxis position = -1.0
ZWCOffset = 0.0
GBH = 0.5
The offset calculation for button in MT mode is:
WCOzOffset = MCZAxisPos - ZWCOffset - G-Blockheight
= -1.0 - 0.0 - 0.5
= -1.5
17) click Set Z Zero
18) Z row of offset panel will change and it should now be:
+0.5 = -1.0 - -1.5 - +0.0 - +0.0
