I was told on an earlier post that Mach-3 Turn has some bugs in the Front-Tool/Rear-Tool definitions, and tht I should list both tools as (say) Front-Tools and use the X-Offset for the Rear-Tool to declare the distance between them.
OK... I have a turning stock chucked up...
Diameter 27.92 mm
Radius 13.96 ..
Start the spindle...
Select Tool #1 (front)
Jog the front tool forward until is just touches the turning stock
Set the "X"=DRO at 13.96
without changing anything, Jog back until the rear tool just touches the back side
Make note of the "X"-DRO... 72.28 and we are at -13.96 for Tool #1 (we still have Tool #1 selected)
So add 13.96 to 72.28... The X=Offset between the tools should be 86.24
Set the X-Ofset for Tool #3, (my "Rear-Tool") at 86.24 (see attached screen shot)
Now with Tool #1 selected...
T0101
G01 X13.96 F150.0
should position the front tool, just touching the front surface, which it does.
Then enter...
T0303
G01 X-13.96 F150.0
should position the rear tool, just touching the rear surface of the turning stock, but it does not.
There must ba a 20 mm gap between the Rear-Tool and the Turning Stock.
Am I doing this incorrectly?
