Tool length offsets
- About the last thing I have to work out are tool length offsets.
I've looked thru the manual but it's a bit light on this subject.
Some while ago Art implimented the touch off routine for tools and set
the table up.
Could some kind soul explain how they go about setting up say two
tools using the top of the work as Zero and touching off and entering
the data to the table.
When I tried, whatever data was in Z got entered but the Z DRO then
went to 0.0 I would have thought that it sayed the same so you could
return up to Z zero.
Next problem is in the UK and Europe we use G44 and not G43. mach 2
doesn't support G44 so can it be fooled by entering a minus number
into the table?
G44 is used here for safety reasons, we zero onto the top of the work
and all moves into the work are -Z moves. Any plus moves takes the
tool out of the work and away from cutting.
In Mill? G43H43
Tool in operation doesnt matter.
In Turn? T1643
