[Emc-users] won't start on line 310 (run from here)

[Stuart Stevenson]

Gentlemen,

Debian Wheezy
latest linuxcnc release - installed today - but the last release did the
same thing
Axis interface
Kasuga 3 axis mill

when starting (run from here) on line 310 I get the error "length of cutter
compensation entry move is not greater than the tool radius"

This only happens when I 'run from here'.
When running through the program the machine runs this code just fine. I
cannot run through the program as I must change tools in the holder - set
the tool length - and - start by picking 'run from here' (right click on
the mouse).

status window shows G40 prior to initiating 'run from here'
after initiating 'run from here' the error shows and the status window
shows G41
mdi g40 resets the status window
reinitiation of 'run from here' shows the error and sets the status window
to G41

Editing the G41 and G40 out of the program allows 'run from here' to start
the machine and run the tool.

Gentlemen,
Debian Wheezy
latest linuxcnc release - installed today - but the last release did the
same thing
Axis interface
Kasuga 3 axis mill
when starting (run from here) on line 310 I get the error "length of cutter
compensation entry move is not greater than the tool radius"

The message clearly indicates the interpreter thinks cutter
radius comp is on.
if it executed the G41 on line N290 but then did NOT execute
the G40 on line N292, then it would still be in G41 offset
mode. Note the displayed modes on the GUI are provided by a
DIFFERENT interpreter that is not aware of the stop and run
from line. If you need to run from line, it might be safest
to insert a line with a G40 there, and run from that line to
be sure the offset is turned off.
