General Mach Discussion / Tool Change Offset issues
« on: December 20, 2011, 01:17:09 PM »
I'm using R3.048.053 with a SmoothStepper and TTS tooling and I'm having a difficult time getting the tool change offsets to work properly.
I set up my ref tool (TTS Dial indicator) as tool 1 and add several other various tools all carefully measured using the Tormach system.
After referencing tool 1 to the top surface of the part, re-zeroing Z, then pushing START. It will call for tool 2, I change to tool 2 & hit start again. As tool 2 moves down to the part it stops at .257 above the surface and begins executing the cut. It's not ramping to the cut depth here .. its executing the entire pocket or profile but cutting nothing but air.
I have tried several things to discover where the problem lies as follows:
Homing the machine & making sure Work Coords = Machine Coords before referencing Tool 1 to the part.
Double checking that I don't have any offset parameters set in G54.
I can also reproduce this by implementing tools changes manually as follows:
From the Program Run screen - manually entering tool numbers into the Tool DRO. (I know that's not the proper way to do it, but it's the way Tormach shows to on their video)
From the Offsets screen - manually entering tool numbers into the Tool Dro.
From MDI - typing t1m6 (enter) then g43h1 (enter) .. or whatever tool number I'm calling for.
In all cases the correct offsets show up in the H dro, but all of the above give the exact same results Z0 = (Z0+.257)
It doesn't matter what tool# is called for .. they all stop short of the surface of the part even if I call for Z0 from MDI.
I've checked & re-checked that I'm measuring the Ref Tool & all others correctly.
When comparing Work Coord to Machine Coord the math adds up when taking tool length offset into account.
I'm stumped & need to get this resolved. I suppose I could uninstall everything and start over with Mach & the smoothstepper software, but I'd rather not have to go there if it's something I'm missing or doing wrong.
