Hi
Wondered if anyone had any experience of adding the G41/G2 command to a Vcarve pro post processor file. In particular I have a Syntec 6MB controller.
Thanks in anticipation

Vectric products do not support G41/G42 in their post processors (or anywhere else).
You'd need to create profile toolpaths on the line and add G41/G42 commands manually to the g-code.

Hi
I didn’t realise that, thought it was just a case of adding it in a similar way to the g43 command as my machine has linear atc.
The reason for the request is that I use a lot of straight twin flute 6mm bits as I cut 12mm hardwood ply (lots of it)
I buy bits from several suppliers but although the diameter is 6mm the actual cut does vary.
So I thought by adjusting the tool wear parameter I could get away without changing the actual files.
Guess that isn’t the case.
Many thanks for your input.

The majority of design programs do nothing for cutter comp other than to output a toolpath that is the exact size of the cut geometry and allow placement of the appropriate Gcodes.
The rest is done at your controller, using data from your tool database, where the radius of the bit is used to provide an offset to the cut geometry. If your controller support cutter comp, then you can add the code via a modification of thr VCPro postP.

The problem with adding the codes to the post, is getting a proper lead in move. If you add the G41/G42 to the end of the First_Feed_Move section, it might work OK.
Some trial and error would definitely be in order.
