Sx3 Problem with circles

Postby B387sjm » Wed Nov 04, 2015 7:43 pm

Hallo everyone..
I possess sx3 and it came with a CNC fusion kit. Whenever I engage on cutting the inside profile circles the machine stops four times as if making 4 arcs and then it completes the full circle rather than finishing the the whole of it all at once. I have been using the cut2d and Mach 3.
The other issue is that the machine was put in CV mode.
How can i correct these?

That because for a machine using the x,y plane their are four reversals whenever you are cutting circles. Two of the them are for the x axis while the other two are for the y axis. It could be that what you are witnessing is the backlash at every reversal of the axis.

I get it now. That clearly explains where the pauses are coming from. Can't believe that i never thought of that. Thank you Sanvan.
