MICROTURN CUTS ARCS BACKWARDS

Post by Steve » Tue 14 Jul , 2009 19:11 pm

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. :doh:

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.

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
