Sheetcam and starfire

[kennye]

Is their anyone that is having success with making nc files with sheetcam ?Ive converted some files with it
some seem to work good while others dont. It maybe me im not sure.thanks Kenny

When it doesn't work what problems are you seeing?

[kennye]

It cuts simple designs but when I start to cut detailed pieces It butchers it up.
Im starting to think because everything is in metric and Im doing everything in inches
maybe some of the problem.A ? tho .Being everything is set up on the machine /speed/kerf/and pierce height
should the tool be set up as usual or left blank and set the machine up to cut to keep having conflicts between software issues?
Thanks for any help.

When you say it butchers the job, do you mean it cuts the wrong shapes? I'm wondering if it's an arc problem. A good test for arc issues is to cut a square with rounded corners and a circle.

What Postprocessor are you using in sheetcam ?
What is the model of your starfire controller?
What THC do you have?

I did a lot of tuning to the post processor to get mine to work really well for both the THC and starfire.

Im using the Baleigh post processor
the controller should be the latest I would think and the thc is built in the controller
I tried to cut last night and I noticed when it got to curves the machine slowed down alot but on
straight lines it did good . WI say butchered I meant it cuts the right shape it just cuts really thin
and cuts out pieces it shouldn't .Its good to know that some are having success that means that I have a programming issue
I would rather stick with something I kno a little about {sheetcam} if possible.I guess Ill keep changing processors until I find 1 that works for me I find one that works and try to keep tweaking the machine Thanks for the help

Is it doubling your kerf comp? Compensating in Sheetcam and then again when you bring the file into your controller. Maybe your just trying to cut too much detail into a small piece. Do you have a couple pictures to post and/or the dxf file that causes issues?

[kennye]

You maybe right about the kerf setting in sheet cam .Do you think I need to leave kerf blank and speed too ? and just set it in
my controller But why would it slow down on cutting curves ? I mean real slow.Ill try to cut some pieces tonight and post some pictures if I can
but Im thinking kerf has a lot to do with it.Thanks

[weldguy]

Slowing down for curves is normal but yours sounds extreme. Yes, I would try leaving speed and kerf blank and allow your controller to handle it and see how that works out. Let us know.

[kennye]

If you dont mind me asking what would be a good processor for it and what would be good kerf settings
all of my settings are in metric so thats got me kinda screwed up too. I have fastcam software that came with the machine
and havent figured it out yet .Learning chinese so thats going to take a little while watching you tube videos.

[Les Newell]

Just a thought - is it sometimes cutting the right shapes but in the wrong place? If so you could be losing steps on the machine.
I just had a look through a starfire manual and the 'Corner speed between conversions angle' parameter may help speed up cutting. The manual isn't very clear but play around with the settings and see if it makes any difference.

Thanks I appreciate an help I can get .I got to get back cutting metal so my wife can sell. Shes on my butt hard.

Change your P to one of the start PP's
Start and starfire are the same thing

In the controller set change your kerf settings to 0
Sheetcam adds the path offset you dont want the controller adding more

Send me a PM and I can send you my updated PP

[kennye]

34by151 I sent you a pm can you let me kno if you got it thanks

34by151 I sent you a pm can you let me kno if you got it thanks

Nope did not get it but sent you one

Hello, please can you send me the post processor with probe and everything that I need from sheetcam to starfire?

[34by151]

Your starfire wont probe it only does the XY axis. The Z axis is controlled via the THC.
What do you have for the THC?

For the PP use the "start" pp
