Radius to end of arc differs from radius to start: error when resuming line

I did a CNC conversion on a longarm quilting machine so frequently need to resume a file from the middle when the thread breaks. I am using GcodeTools from within Inkscape to generate the gcode from vector art.  The attached code runs fine, but generates the dreaded arc error when attempting to restart at a specific line.  The GCodetools extension has few options for postprocessing, so wondering if there is a setting or GCode  within Linuxcnc I can use to make this work.  Path accuracy is not a big deal since we are talking about a quilt here.

I am using Touchy as interface.

You need a G1 move to the last X Y position, before the starting line
