MICROTURN CUTS ARCS BACKWARDS

[Steve]

I have a microurn and am designing with LatheCAM Designer.

There is an arc that cuts 90 degrees from the center out to about 1/2" diameter in a clockwise direction.

When the machine trys to make the finishing cut it moves 270 degrees in a counter clockwise direction.

If it did not crash it woud then cut the part correctly.

I am sure I have to change a setting in a post file somewhere but cannot remember which one.

I was using the Mictoturn Imperial Post.

Please can you advise where the file is located and what needs to be changed.

Steve,

Is this what you mean ?

Thanks Graham!

This is what I needed.

I had looked in the Fanucl.ini because I had already edited the file extension to be FNL not FNC.

I just missed the bit below as I was looking for G02 and G03.

May be we should have a software section for MillCAM and LatheCAM?

When is this INI file created? Is it when Lathecam is installed?

Is this fixed on the current version of LatheCAM?

Anyway the solution is below:


This way you will not have to manually change the G Codes. However in 2D/3D simulation it will be wrong, as the tool is coming in from the back side of the material.

Search for the fanucl.ini file and found in C:\Denford\Config.
Open the fanucl.ini file in Notepad and scroll down until you find CNC Lathe (inches) and add the lines
CWCode=3
CCWCode=2
Then scroll down farther until you find Microturn (inches) and add the lines
CWCode=3
CCWCode=2

Note:

If you have a Lathe that has a manual front cutting toolpost then the changes above need to be made.

If you are using a metric post they need to be set in Microturn Metric and Lathe Metric too
