Basically having issues controlling the threadmilling cycle which should be fairly straightforward. I’m getting two errors depending on where enter the threadmills radius. First error is PS0020: Over Tolerance of Radius. Using a 9.9MM diameter 1/4 NPT threadmill. The second error is PS0041 Interference in G41/G42 when entering the 4.45mm radius in the geometry page. The code is as follows

G97 S2000 M13;
X50.878 Y0.0 Z24.486;
M484
X0.0 Z20.;
G10.9 X0.0 (RADIUS) ( have entered radiuses from 5mm down to 4mm in here in X value);
Z-10.3283;
G01 G41 X0.941 Y-5.5197 F20.;
G03 X4.5723 Y4.5723 Z-10.0296 I-6.4634 J.0067 F52;
.....

G10.9 (Dia) (this line as at the end of the process

Thanks in advance.
 
I assume this is the same machine and the same hole that you were talking about drilling in an earlier thread.

First off I don't have a programming manual to know what G10.9 is or how it's used. I think/guess it's just a toggle for Diameter (lathe) mode and Radius (mill)?

Your errors are probably coming from the very goofy looking numbers in the G03 line shown or the ones after.
 
You’re missing a D. Don’t know if that will fix anything.

Edit to add: If for some reason your control doesn't need a D, your lead-in move needs to be bigger than the value in your radius/dia. comp.

The Thread title is weird- at an "incline"? Does that mean he's trying to Threadmill an NPT at an angle? He's also using M13 to activate the Spindle. IDK.
