I see no one got back to you on this so I will. I have a Novakon torus pro that is controlled by an acorn. Most, if not all of the issues I had with it were related to the control at least as far as cutting aluminum were caused by the Mach 3 control. The upgrade from Mach 3 to an acorn board was 100 ...

If you haven't tried or used the WMPG you don't know what you are missing. It is a real time saver.

I could not agree more with this. The WMPG has been worth every penny to me.

I'm impressed with your accuracy Uwe. I have not seen one yet that was consistently that good.

I am not sure what you mean by negative or positive stock? Are you saying I should adjust the dimensions of the model?


No it's where you set up your CAM. You make the model in full size. When you are generating tool paths it is a setting in the cam that I use. You tell the tool path to leave or ...

You can also change the finished dimensions by using negative and positive stock to leave in your tool paths instead of adjusting tool diameter.

I should have clarified my response was to the original poster. He quoted dimensions like .75339 and .75375. That is way beyond what can be expected for accuracy on a hobby mill.

I think you may be expecting a lot from a hobby mill. Are you actually measuring to 5 decimal places? Being off by a few thousandths of an inch can be easily explained by deflection on a hobby mill with a small end mill with lots of stick out. I generally consider something within .005" to be ok ...

You have a setting wrong. I can't remember what it is called exactly because I set it long ago. You want to be in diameter mode not absolute or something like that. When you command a move on X it should be half of what was commanded because you are removing material from both sides of the work piece.

Notepad++ has a compare function. It's an add on but easy to install.

No matter what turret you have or how it works the PLC can be edited to make it work. You may need an experienced persons help to edit though.
