Has anyone had a problem with a DMC80FD machine with a SINUMERIK 840D/840Di control erroring out on arcs to small when you turn filter on in the high speed tool paths?

[gcode]

you can adjust arc output size on the tolerance page of your control definiton and you can also set a minumum size

 

on the filter settings page. You should be able to tweak the settings and make your machine happy

I had the minumum radius set at .2 and still could not make the machine happy! If I turn the filter off the machine will run but the post is still outputting radii when it is plunging but the control is happy with that! And that radius is .075!

[gcode]

are you filetring all 3 axis or just X and Y

[Todd Mann from Fastech]

All three but it is only moving in x and y when it errors out.

High speed machining in the 840D likes linear moves. You can go point to point and let the control smooth everything out. If memory serves correctly it is the arc length that the 840 doesn't like. The length needs to be at least .010". Again this is from memory and I don't know how accurate it is. LOL!!

 

I will see if I still have my 840D control def packed away. I used one at my last job.
