Milltronics Mill Verify doesn't match Fusion 360

[benjamin.zhuk]

I'm using a Milltronics mill post processor and the code is attached.

When trying to execute the following block number the machine crashes into the part. It interpolates a clockwise arc but it's not shown in my Fusion simulation.

N263 G17 G2 X2.7707 Y-9.4932 I-2.2635 J1.2149

By disabling a "lead out" the controller verification simulation matches Fusion360 and machines the part without crashing

I've been using Fusion for a couple of years with this machine and this is the first time I see this mismatch between the  Fusion simulation and the controller verification

It looks like just turning off the Vertical Radius on your Lead-In/Out should solve this issue?

[benjamin.zhuk]

Any idea why the controller would not like those lead in/out settings? Post processor issue?

[seth.madore]

I'm not certain, to be honest. Are you always using the generic post processor, or did you insulate yourself from any undesired changes and save the post processor locally?

[benjamin.zhuk]

My post is shown below under local. Would this mean I'm isolated from updates? Or does the local gets a force update.

[seth.madore]

You are insulated from updates, provided you don't click the orange icon to the right side.

[seth.madore]

It could be a tolerance issue I suppose. These can be a bit hard to track down, honestly.

Hi @benjamin.zhuk 

i have simulated the code in HSM Edit, and it give the result below.

General result :

The arc is somewhere in the green ellipse.

Closer look of the arc.

It's an real arc, after the linearized arc used for ramping in the material.

We had a slightly different situation some lines before, but this time the arc was in the G19 plane.

It's strange that the machine collided here.

As all coordinates are presents, the manual is saying that G17/18/19 can appear anywhere on the line, and the arc is supporting XY IJ and G17/18/19 on the same line.

So, it's hard to explain.

Regards.
