Centroid Community CNC Support Forum

Thanks Keith,

Its amazing how accurate it works as a lathe and it keeps excellent tolerance.

I have been using Acorn CNC for a while on our conversion and because we have no CNC lathe its also setup to turn parts.

I used wear compensation

Thank you I think this is the way I will have to go.

Sorry about that: Machine Parameter 99 (corrected above as well). Thanks for the pointers, I have just tried that and it still does not fix the problem, I am convinced that its a problem with the software and Centroid should look in to fixing it. This does not happen on any other machine as far as ...

Also just to add a bit more information I am running the latest version of Acorn and this has been an on going issue with all the versions I have used. Everything else works great.

I have had a look at the machine parameter 6 but it says its to enable an automatic tool changer. I does not seem to make a difference if i set it to 1.

Acorn cuts a gouge out of the part when it reaches the circle on the screenshot.

Hi,

Could somebody please explain why Acorn fails to follow the programmed path correctly when cutter compensation is applied on this profile.

I have attached a screen shot showing the error, and the code being used.

Hi Marty,

Thanks for your help with this issue, we have now decided to just keep the DYN4 servo for a 4th axis when we make one and buy a 3 phase 1.1kw motor and VFD for the spindle.

We will use a separate encoder for feedback if we need to do rigid tapping.

Thanks again
Phil

Thanks Marty,

I will post a fresh report tomorrow when i get back in the workshop.

The acorn board is mounted just below where the relay board is.
