Title: MESH CAM AND TOOL DIA
Post by: GRAYHIL on May 28, 2015, 09:19:04 AM

Hi All
Have a registered copy of Mesh Cam and Mach3 version 062
Produced a long G Code program but it wont "read" the tool table and allow for 1/8 ball tool diameter.
I have put all the tool dimensions in mesh cam against a tool number which it puts in the code.
The same diameter is in the Mach 3 tool table against the same tool number.
When I run the program it asks for a tool change and shows the tool number and diameter on the screen display.
However rather cutting the parts to the correct size it machines them 1/8 under size in all directions.

Can anyone help or suggest which setting I have wrong???
Attached is code produced.

1) Mach3 can not do 3D radius compensation. (I'm not sure if any controls can, as they wouldn't know where the actual part is).

2) If you have the correct tool information in MeshCAM, then the g-code should be offset from the surface of your part by 1/16" everywhere.

I have run mesh cam before with no problems;
See attached photos of steps I followed.

A thought
Will it get to the correct sizes as it gets down to the face of the "OBLONG WITH ROUND ENDS" face which is lower than the top surface as excluded on the left hand side.
Will have to run it through on some plastic too see.
