BobCAD CAM Post for Multicam

[aldepoalo]

Hello Everyone,

I am making changes to a post processor for multicam routers. I have a few questions, can you help.

1) Are the feed rate setups different from one mulitcam router to the next?

A. inches per min

B. inches per second

C. inches per feet

What is common on this controller and can they be changed from one to the other and if so how is that done.


2) I would like to comment out tool information so when you are looking at a program you know what tools are being used. Does the multicam support comments and if so how.

Nice, based on that document "//" will comment out the block.

Thanks for the quick reply : )

Al...

Your question caught my attention today as I just set up a multicam router with bobcad v28 and quickly discovered the multicam controller operates in ips, a question you asked about. multicam told me they don't have a way to change it to ipm, which is what bobcad uses.

And a call to bobcad tech support didn't help.

Did you come up with a way to translate so the post outputs the correct feeds?

Yes, old thread, sorry to dredge it up.
