Sure do, and this gets repeated over and over.... You do not have a valid tool offsets in the system. You MUST verify one is in place prior to setting the work Z reference.

Your screen should read: T3 H3 not T3 H---

Hi Gary,
I realize that, I believe, but how do I get that tool offset to show up upon power up. Say I command the first tool for the job from the tool rack. Once the machine loads the tool shouldn't the height offset be T3 H3? All my tool offsets are setup in the tool library.
Thank you
Bill

Height offsets are not loaded until a G43 or G44 command is issued. Executing an M6 T3 tells the control to load tool 3. Nothing more. You then need a G43 H3 if you want to assign that offset to that tool. You can then set your part zero using that tool.
Cheers,

Tom

Yeah, I thought I had it resolved when I added the G43 at the end of my M6 as you can see in the picture. I don't really know why sometimes it works and other times it does not. Right now it is working.

I don't believe a tool is "loaded" until the M6 macro returns so doing a length compensation inside the macro would not work because it is turned off when the new tool is loaded.

You mentioned power up. You will always have load a tool after startup or enter the G43 command if one was left in when shut down

Ok, I thought having parameter 3 set to 2 would cause cnc12 to remember the last tool in spindle. That is what it seems to be doing now when I leave a tool in from the previous day after a power up. So far all good.
Another question:

I want to speed up the ATC feed rates for the slide in and out of the tool rack, right now they are at 50ipm. I want to increase that as well as make the Z movement pauses a little shorter. Where do I find that code to edit?

Thank you
Bill

open the tool change macros found here.
rack atc speed.png
and near the bottom the L command is the speed in inches per minute or mm/min


N600 ;Position of Tool (Based on Clearance Axis)
G53 X0 L50
GOTO 1000

N700 ;Cleared Position of Tool (Based on Clearance Axis)
G53 X0 L50

N1000

Great, I was looking at those macros, that is what I thought, just wanted to be sure.
How about the G4 pauses in the Z axis moves during the tool changes. Where are those?

Thank you

open the mfunc6.mac (tool change macro located in the cncm directory) that will lead you to all the other macros that are used by M6
