hi to all,
i am using latest Mach3 version R3.043.067. i problems that i face
1)when tool compensation g41 or g42 is used the inner circle dosent seem to close when i stimulate & also run it online using machine.
i have attached the g code and screen short of the eg files.
[sq size50x50 with fillet 5mm and inner 20 dia circle]
2)the reverse run command also dosent work well. please clarify how to use this command.
-----------------------------
regards,

Probably best to use the lockdown to see if its ok with it. Even the lockdown has issues for me with Turn but Mill seems fine.

hi hood,
thanks for your reply.
the problem still exists in previous lock down version(ie)066.
anyway i have got a solution for now(ie)if i add dummy lead out(g01 x35 y25) after g03 command it closes the circle.
lead in/ led out are critical in case of cutter compensation i guess.

Yes you need them :)

My opinion is:
- For an inner circle you must position in the circle close to the starting point G00 X30 Y20.
- Approximate z workpiece G00 Z1.
- Program Z-2 F200.
- Program G01 G41 (not G42) X35 Y25 F400 D01.
- Program G03 X35 Y25 I-10 J0.
- Program G01 X40 yY30.
- Program G00-G40 Z5.
this should work.

@ jdmaya,
generally mill/router wont require lead in&out .so i tried using dummy leadout by specifying the end point of circle.

ALL tool comp work (G41/42) MUST have a proper leadin and leadout move to work properly.
