Hi, I am machining a jig, and I'm having an issue with one of my patterned toolpaths.
Current Issue
The root (original features) get machined fine, but the pattern is adding a large circular cut that is not supposed to be there. Bummer because this is a $200 piece of aluminum.
I find it odd that this is only happening on this patterned feature (there are several in the program) and the root of the pattern is coming out perfect! It's just the duplicates that are flawed. Another thing I should point out is this unwanted move happens very fast and the machine makes a loud "clunk" sound, as if there's a very abrupt movement happening.
Fusion simulations appear to be correct, and I also dropped the gcode in ncviewer and it also looked correct. I figured it could be an issue with my machine (Milltronics VM20), but the fact that the root is showing up fine makes me believe Fusion is adding something only to the patterned toolpaths. I would appreciate if anyone here has any recommendations or solutions. This was a roughing operation and there are more ops to follow (in this pattern) and I am nervous about running it and doing further damage to this 30+lb piece of aluminum.
Previous Pattern Issue (might be related)
I had some issues with Fusion patterns the other day (same project), but it had to do with rest machining not working if the "keep original" feature in the pattern settings was unchecked. My solution to that was to select "keep original" (even though it had already been cut) and just cut air until it reaches the desired area where the patterns start. This was a whole different issue but it leads me to believe that my current issue may be related to a flaw in the fusion patterns feature, since I have been having trouble with it prior to this issue.
My First Post Here, Thanks For Your Time!
That being said, I am relatively new to machining. This could be something obvious that is completely my fault, but it's just so odd, and I've reached out to a few machinist friends (who also use Fusion) and they haven't ran into an issue like this.
See image of material attached. Project linked. REV02 OP3 is the setup where these issues are popping up.
