Solid Works to old Mastercam 9.1 correct file transfer format ??

[MrRogue]

Hello,

Yes yes I know MC9.1 s old but it's what I've got until I can buy the MC for SW at some point....

I have solidWorks Pro 2013. I'm learning my way into it. I have completed several basic design drawing now. I've been trying to transfer the drawings into an older version I have of MasterCam 9.1.
I've found a few different ways to get the wire frame / shaded drawing onto MC9.1 but when I set up my tool paths and run it in the cnc machines..... What I see on the computer is not what I'm getting in the machine....... :-(

Can anyone tell me the best procedure to fallow for these two programs? I would like to get MC for SW but can not buy it right now.

Picture 3:
Is "back plot" using the "step" feature using the "S" key to make the process go one step at a time. You can see once it gets into the arc it starts looking like there is a bunch of short lines making up the arc. I think this it the problem but not sure how to salve it. I think it has to do with the file transfer type from SW to MC9.1

Picture 2:
This is what happened in the cnc machine when cutting...... It added an LOOP to the middle, inside part of the arc.
This was NOT part of the drawing. It was not seen in the Verify on screen or the Back Plot check on screen.

Picture 1:
This is "back Plot" feature using the "run" where it runs the entire tool path through unlike the "step" by "step"... In this feature when "run" is selected it goes through the tool path and you see a smooth tooling line in the drawing. Same geometry and same tool path but different visual outcome with the "run" vs, the "step"

I'd like to find an be able to fallow a good example of file transfer between the two programs.

thanks,

In pic #3, when :Stepping" you are going to the endpoint of each entity, R is just stepping continuously
- top left corner (Backplot dialog box) is a double arrow pointing downward, this is a expands to a detailed view of the path info, so when you analyse segments of the problem arc....is it doing G2 (CW) arc or G1 (linear) moves ?

If linear & drawing is an arc, you don't have the "Filter" enabled & you need to enable the G17 (XY) arcs
if a series of arcs, maybe they are not "blended" or trimmed correctly
if a spline, it only gives point to point.....unless you redraw to make arcs

I ended up DELETING the "SPLINE" geometry but by then I got a part cut and the customer bailed on me and left me hanging with the bill.

moved forward.....
