Hey guys,
Im a new SheetCam user and I have a few issues.
I have Version 1 Flashcut CNC and I only have a X and Y axis so I use the FlashCut no Z post processor and export as G code.
When I load up the G code my circles are not showing, the simulator shows them with no isses…
I have the most recent release of SheetCam and have tried uploading and reimporting the code, I even ran it in a different post processor and then back to FlashCut no Z… Still no circles.
I also see in the simulator that my torch is not firing at the beginning of my lead in, it goes along the path of the lead in and then stops and fires the torch on the edge of the circle.
I dont really want to edit every single string of G code to correct these circles…
Any help will be greatly appreciated.
So, in the previous post I said that I didnt want to edit the G code to fix these circles… well honestly after getting back into the program again I can’t seem to figure out how to correct the G code.
searching all over this forum I cannot find anything that will correct this…
Could you post a copy of the code here so I can see what is going on. Is this on a plasma cutter?
Yes, Plasma Cutter and I sure will.
Tonight when I get home. Thanks so much.
Here is the .DXF and the G Code that Sheet Cam generates.

I tried a few other post processes related to FlashCut and nothing would work with circles.
I found a similar post/problem on the forum that had me delete 4 lines under the edit post area… no change in the circles, it still is working fine for other projects that dont have full circles.
Actually it is making my life so much easier, I love Sheetcam! Money well spent.
I sure hope this can be fixed…
Try this version. Does it work?

So, that G-Code worked like a charm!
I can see that you changed this line for both circles:
N0130 G03 X1.4425 Y9.9225 I0.0000 J0.7137 F60.0
It was showing this before:
N0130 G03 I0.0000 J0.7137 F60.0
So my question is… Did you have a different post processor that generated this or did you rely on your awesomeness and technical prowess in G-Code?
Very much appreciated.
Sorry it took me so long to get back to you. I have been out of the office a lot recently. I have come across this issue before on another controller. While the code generated by the post is valid, it looks like earlier versions of Flashcut get confused by the missing X and Y coordinates. The attached post should fix it.
Save the post to any convenient folder the run SheetCam and go to Options->machine->post processor. Click on the ‘import post’ button and open the post. Go back to Options->machine->post processor and make sure you have the edited version of the post selected.
Looking good to me!
Ill run it past the machine since clearly it is the boss of this entire operation… Ill ask it for a raise for you also!
Thanks for the superior support!
