First chips; My PP woes?
« on: November 04, 2008, 12:56:19 PM »
So I finally made my first chips.

I'm having a problem that is possibly post processor related but I really don't know.

I'm running mastercam v8.2 and mach3. Default fanuc post processor. I've tried downloading two other post processors intended for mastercam and mach3 but they freeze up when I try to post. I would guess they're meant for a later version of mastercam?

The first thing the machine does is g0x0y0 and then plunge g1z-.08. It backs up and then continues on with what it is suppose to do. The initial plunge was not programmed in nor intended. It is suppose to start with pocketing two holes at a different location.  I've verified with mastercam and can't figure out what the problem is.

Any ideas?

Thanks,
Adam

Have a look in your tool table and see if you have any offsets for tool 1.
 If not then can you tell me exactly which line the Z plunges.

N118 is the line where it plunges -.08 What's the N118 for?

I don't know what my tool table is. Is this something in mastercam or mach3?

The code is telling it to plunge by that amount so you need to look in your CAM or PostProcessor and see why it is doing that.
The N118 is simply a line number, some people like line numbers as it makes editing code easier as they can go to a line easier when its numbered. I prefer not to have them but everyone to their own. Again this should be an option you could ediit in your post processor.

Hmm,

I've looked at the fanuc post and have not idea what I would need to edit, though it does say that it is a generic post and should need editing.

I've also tried looking for other posts that people have been successful with but every time I try to post in mastercam, the machine hangs up and I get the hourglass indefinitely. I presume because the post is for a newer version of mastercam?

Thanks,
Adam

I dont use MasterCAM so cant really help but there is a chance it could even be in MasterCAM itself that you need to change a setting.
