I used Turbocad v12 to draw a simple irregular 4-sided polygon with two 1/4" holes and created a dxf. LCam generates almost 250 tiny line segments for the first circle rather than a circle instruction and halts at step 250. The polygon sides and the second hole are not in the gcode. What am I doing wrong? Does TurboCad have a conflict with LCam? KCam4 generated gcode runs great on Mach3. Mach3 runs my machine three times faster & smoother than KCam4!

Robert, are you running the Demo version of Mach?

Yes, I am running the demo version. Is the demo version limited by other things than the 250 line limit of gcode? Usually DXF files with arcs or circles convert to have the I & J commands in gcode. I tried another drawing with three sides and an arc and LCam gave me G2 gcode with I & J codes for the arc. I am going to put the 1/4" dia circles into it and see what happens. I tried with points instead of circles knowing that my cutting tool was 1/4", and I would get the right size hole, but the points were ignored by LCam. Also, LCam gave me four chains: one with nothing in it, one with two corner touching lines in it, one with one line and one with the arc. In addition there was a rapid, backtracking the single line, which seemed to serve no purpose.

Hi, I am using TruboCad , LazyCam, Mach3, and a Zenbot. I was able to solve a lot of my problems by drawing in model space, setting a origin, and saving as .dxf file using TurboCad. I will say that sometime LazyCad does do some odd things that requires a restart. Best Regards.
