HELP! Lathe Tool Offsets Something's Rotten in Denmark
« on: March 21, 2017, 06:27:07 PM »
Ok finally got my Mori Retrofit up and running and can't figure out how to setup tooling. Watched the video, read the manuals, but something is amiss.

Here's what I'm doing. Start machine > Ref Homing > Set Tool 0101 > Turn off my servos so when they come back on they go to a Zero Index (mach is not aware of this happening) > While the servos are off I use the MDI to make sure BOTH Machine POS Toggle and Normal DRO are both at ZERO > turn the servos back on and they automatically home to the zero index (again with Mach unaware and both DROs stay at Zero)

Then I jog over and cut on the X to achieve a 1" OD turn > open tool table > and hit the Set X Offset (which is set a 1") > Normal DRO now reads X-1.0001 and the tool table X reads -1.3067. Now from homing (which because of the zero index is dead accurate) if I go to where X will cut a 1" OD that is -3.6134. So here's where I'm confused, first off why is the offset at a negative? I put in the Set X Offset 1" NOT -1". And the Machine Pos Toggle, on the X, is half of the Normal DRO so in the Tool Table under X shouldn't it read -1.8067?

I'm at a loss here. Any help would be appreciated.
