OK guys i got the touch probe working (ish)
The bit touches the ali plate - stops and backs off
comes down again slower - stops
but rather than reset above it drives the tool down!!
for the purpose of the video - "PLEASE NOTE: No innocent tools were hurt in the making of this video. collet is loose and the tool is wounded volunteer" the thud at the end is the escape key being pressed.
Presume your using gerry's screen set.?
Have you set the clearence plane.? and is the number positive not negative.?
With all the issues you have been having with changing axis directions etc could you possible have the Z axis going in wrong direction.? IE down = positive Z axis are nearly always negative moves down with positive up.!
Test by zeroing dro clear of any obstructions and typing G1 Z-5 F100 in the MDI box. This will move nice an slow 5mm down. If goes up your set wrong.!
went into the simple zero file does this make sense?
Else ' Off = Metric Measure MM
FirstProbeDist = 150.0 ' Probe down 150mm
FirstRetractDist = 1.0 ' Then retract 1mm
SecProbeDist = 6.0 ' Then probe down 6mm
FirstProbeFeed = 250.0 ' First probe feed @ 250 mm/min
SecondProbeFeed = 25.0 ' Second probe feed @ 25 mm/min
ClearAllow = 2.0 ' Max Allowable Clearance = Z Machine Zero - 2mm
i cant read that lol
now sorted... doesnt make sense to me however. set the material clearance to 20mm then an offset of 4.3 and its spot on.
Sorry Gerry, did I spoil it for you by leaving it loose lol sorry pal.
Wife's just cooking me some steak and peppercorn sauce, I can't go anywhere until I've destroyed it, so will pop to the factory afterwards and let you know.

I will reset to default values and do another video for you Gerry with screen included
OK after setting back to defaults (when the bit plunges) it says that the "Z axis is now Zeroed"
Ok Setting back to defaults with 3mm clearance. still goes down.
Second attempt, with clearance set to 20mm Goes up! but plunges too far when set to top of work piece.
Third attempt, works great with a 5.3 offset and same settings as above. go to zero and it just kisses the work piece
i do have safe Z set in mach would that affect it (Back at home now)
