Is it possible you’re using an old version of Fusion or an old post processor? The G code isn’t outputting G6.2 codes, which I would expect when using TCPC. It seems like the tool isn’t being properly positioned before entering TCPC, which leads to an incorrect arc move.
That one is also missing G6.2 codes, but the toolpath properly outputs an X, Y and Z position before going into an arc move in TCPC, so the issue is luckily avoided. If all that is changing is the tool length, I would expect that program to work with a different tool.
yeah thanks sorry i was out town
you are right it works perfectly with the long tool
so what should i do to avoid this problem - Change the cam ? update fusion ? i understand that its a post possess error
I would definitely recommend staying up to date with Fusion. Are you using the latest Pocket NC post? There will soon be a Penta Machine post that replaces the Pocket NC one, but either one should properly output those G6.2 codes.
