Hello,

I really need some light on this trouble, please.

I am trying to make my rotary axis more useful,
searched and installed several different version of post processor for mach3 (or generic fanuc 4x)
and looking into all of them, modifying a little bit here and there.

while testing the post processor, I found this to be very weird and couldn't figure where the source of it is located.

This is the shape of the model

Attachment 408074

Attachment 408072

as is seen in the screenshot of g-code, this zone makes the weird situation.

1. it happens when it tries to approach to its first cutting level

2. its generated using @move_5x procedure, traced it many times, it never calls @line_4x or @move_4x. only @line_5x or @move_5x

3. it splits the whole distance into very small pieces, and that even happens in pure-z-level-movement, which was splitted exactly every 2mm

4. CV mode doesn't help situation with G0 moves...

so I temporarily edited @move_5x to have G1 instead of G0


what is unclear to me is the source of this trouble.


- it might be SC's own bug in logic
- not a bug but wrong toolpath strategy(or option)?
- it might be wrong machine setup with VMID (but which one???)
- incomplete post processor

I actually test-cut this shape and it seems like there is no wrong movement other than this.


Can someone point me the direction where to look???

tks, Kevin

I am attaching this g-code.
