Multiple Tool paths and start next one from end of last path?

[Onawa220]

I'm sure I am just not searching for the right setting. I sometimes have 4 or 5 tool paths using the same tool that I group together when saving as one cut file. Each toolpath needs to be cut in the order the are saved in (inside first, outside last etc) but most times the start of the next toolpath will send the machine back to 0,0,0 before starting its cut. Is there a setting to keep this from happening while still maintain the order of which toolpaths get cut (I know about merging toolpaths but that would mess up the order).

Thanks and feel free to send me to an already answered topic thread.

Which post processor do you use?

I would expect that the post processor that you are using has a command to go to the (0,0,0) point when starting a new "segment".

The area to look would be the section starting with:

Code: Select all

begin NEW_SEGMENT

I expect that there will be an "M3[S]" command to change the spindle speed in case the new toolpath segment has a different speed than the previous one.

I also expect that you'll find something similar to the following:

Code: Select all

"[N] G0 [XH][YH][ZH]"

Which is sending it "home".

Did you look at the "Group by Part" option when doing the toolpath merging?

I saw that but the video tutorial said it "tries" to keep the inside first outside last in the correct order so I've been a little leery of trying it on the cut I am trying to get this to work on since it is dozens of parts and very expensive plywood. I always try to watch the simulation but I tend to miss things

The only time I've had it go wrong on me was when there was an error with the vectors themselves that I hadn't picked up and it would have been likely that the error would have caused an issue with any sort of multi-vector toolpath.

Not to say it won't go wrong in some circumstances that I haven't come across but I'm confident enough that I even use it on carbon fibre sheets which are very, very expensive. Of course on those I always use the "Run to Retract" option on the preview first so I can see exactly how it's cutting. Running the preview that way makes it very obvious if something is out of sequence.
