What is the difference from Clearence Height and Safe Height
Cause i need to implement it to the cicle

i can get:
obj.ClearanceHeight = 6.00005 mm
obj.RetractHeight = 10 mm
obj.SafeHeight = 4.00005 mm
obj.StartDepth = 1.00005 mm

RetractHeight it's ClearanceHeight + SafeHeight ?

And it's always the same?

Ok, so the tool go back to Clearence Height for movements
But, if i have no clumps, i can set Clearence Height = Safe Height and this is ok
Can be made something like this?

I know i'm inside the stock but if the piece is already worked it's a time waster the distance from Clearence Height to Start Depth
It change if i use G99 ?

Is i'm asking for futile things, but the use of "Safe Height" should allow a vertical rapid movent from Clearence Height befor start drilling

You can set clearance in the job setup and you can set clearance height in each Path operation.

I'm not sure on what to do if these values are greyed

That means they are set by a calculated expression. Click on the f(x) symbol to edit them. See Expressions.

Ok i think i made it more comfortable

Code: Select all

</Path>
obj.RetractHeight = 5 mm
obj.ReturnLevel = G98
obj.SafeHeight = -11 mm
obj.StartDepth = -16 mm

And the result:

Code: Select all

3 L X-135.000 Y-11.000 R0 FMAX M

11 L X135.000 Y-51.000 R0 FMAX M
12 CYCLE CALL M
13 L Z5.000 R0 FMAX M5
14 END PGM DRILL MM

Where we have the surface at Z-16
So th cycle goes to Z-60 cause we start at Z+5, -21 is the distance from cycle call and the surface (5+16), 44 is the depth (+5 -21 -44 = -60)

I will update the the file on the fist post
