im having trouble with sheetcam

[jakeinc17]

i build my parts in solid works, import the dxf from solid works into sheet cam, then add my lead in lead out and kerf then build the g code. once the g code is made in sheet cam, i try to open it in dynatorch software however it says the part is too large. its like 8,000,000" X 8,000,000" when the part is actually 1" X 2". im sure there is an issue with my sheet cam, maybe the post processor or something. i cant get les newell to help me, has anyone had this issue before or can think of a fix?

thanks

Sounds like either SheetCAM or the import program is in the wrong "units" (inches VS mm) or there is a problem on the import side..
Make sure you have SheetCAM set to the same units as your Dynatorch software. Look at the G-code you get from SheetCAM. Are the numbers crazy? If they are what they should be, then there is nothing wrong with SheetCAM. You may have a format problem (they way the numbers are formatted with leading zeros maybe). The whole key is what the G-code looks like. The WAY the g-code is formatted is controlled by the POST processor in SheetCAM. Especially important is the way the arcs are handled in the G02 and G03 sequence between different controllers.

have you checked your settings in solidworks?? When saving drawing files as dxf of dwg's is the save at 1:1 box checked??

thanks for the reply guys, the units in both sheet cam and solid works are correctly in inches. i will check the 1:1 box in solid works however i dont see that being an issue because if i directly place the dxf from solid works into dynatorch software the sizes are exact. torchhead, when you say check the g code numbers, what would be the normal range so i can rule that out. thanks a bunch guys for the imput, i hope i can figure this out.

In my experience, Les has always been very helpful.
Usually he needs you to send him the files though. He needs to be able to duplicate what you're seeing.

I also use Sheetcam much like you do. But I start from Rhino3D, use a convert to arcs function, then export as DXF. Run that DXF through Sheetcam and apply the included Dynatorch post-processor. Voila. No problems.

Now if I forget to "convert to arcs" the splines cause problems and make my curves look awkward.

I did get a similar problem to what you're describing when I used CorelDraw. The part wouldn't open in Dynatorch, because the extents were "off the map." If I remember correctly, it had something to do with the DXF format I was exporting in. Does SolidWorks give you options for DXF compatibility (it should)?
