Bruce,

Try to not edit your tool table outside of Axis.  In EMC2.4.6 the tool table is 
edited from a pulldown menu in the Axis interface.  When a tool call (Tx M6) is 
performed either in MDI or from a G-code program running, the values for your 
tool diameter and length will be displayed in the lower left corner of the Axis 
interface.  It's safe practice to always look there before running.
If these values are active (displayed) then they will be used for G41 Cutter 
Compensation Left and G43 Tool Length Compensation.  It is also good practice 
to put these in a XY move block and Z move block respectively.
After the cancel codes G40 and G49 are active, the display will read "no tool".
I hope this helps, because I am unclear what you mean when you say it is not 
working or what that error means.

Jim

I don't run the very latest EMC on my production machine, and there has
been some
work on the tool table and tool table editor since then.  If anyone else
knows,
please jump in.  Anyway, this is an EMC/Axis issue and is very unlikely to
have anything to do with my servo interface.
