Hi,

If a manual toolchange is called (M6 T2) and G41 and G43 are already in effect, after a lead-out and lead-in move to get the spindle in position for actual toolchanging, will the new offsets be applied for the following cuts?

I know G41 and G42 use the values of the tool in the spindle (as shown on the "run" screen) if no offsets are specified in the code, but does G43 use a similar strategy or do i have to tell it which tool slot to get its length offset from? As ever, thanks in advance

You should do a G40 before a tool change, and re-call the G41/G42 after. You're asking for trouble if you don't. It may not even work.

Not sure, but the G43 may stay in effect, but I believe it will be with the previous offset.

best to cancel before toolchanges and reapply afterwards then - both tool diameters and lengths. ok

i HAVE TRIED TO ACTIVATE G41/G42  AND IT WILL NOT TAKE

bit of an old one to dig up, but here goes. Have you programmed your tool diameter and length in the tool table and told the machine which tool to use?

should go something like

g40 g49 (cancels radius and length offsets)

M6 T7 (calls a toolchange to tool 7 in the table. may pause here if you have told it to, or call a macro, or just charge through - your settings)

g43 h7 (activates a length (H for Height) offset based on the dimensions of tool 7

g41 or G40 (activates radius offset right or left, based on tool 7's dimensions.

Quick introductory move and you're there I'd be surprised if you're not.

the tool change is the surest way to make sure your program knows what tool it's using. Pop it in there and it's done, no messing about in future.

HELLO AS YOU CAN SEE IN MY POST THAT i AM HAVING PROBLEMS USING THE CUTTER COMP GCODE i TRIED ADDING IT IN ON THE GCODE EDIT AND IT WON'T WORK. PLEASE HELP  THANKS

hi there

post the code you're trying to run and I'll have a look.

can you give me any ideas why when I home my machine it constantly gives me a different number and why can't I save a g54 fixture even when i save it it always goes to a different location. Thanks

Can you attach your xml please, sounds like a config issue.

are you asking for my xml? and if so, please forgive me I am new to this so where would I find it.
