Cheers JAZZ,

yeah im using said screenset.

I done G1 Z-5 F100 and the axis goes down 5mm

Clearance is +5.000

still driving intop the plate

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.

Those are hard coded default values, and have nothing to do with the issue.

Really, there should be no way that it can plunge down after probing.

I'd need to know what the message on the screen said after it plunged down.

PS. Your collet nut is too loose.

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.

[D-man]

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"

video uploading

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)

Right, this is embarrassing!

for starters my plate thickness is not 16mm! i cut a 5mm pocket where it sits on the corner of the workpiece!! so in actual fact it is 11mm!!

i shall let you know if anything changes!

[D-man]

nope! still drives into the plate after the second touch
