Santinelli 3D-fit Edger LE-7070 For Sale - Parts or Repairs

I am selling a used Santinelli LE 7070 edger on Ebay for parts or possible repair.

I haven't used this machine in 2 years since the tracer kept malfunctioning . Recently the tracer doesn't work at all so I am selling it for parts or if you have the skills to fix it.
The unit still turns on and does the initial movement. The unit does not have the metal back panel anymore since I took it to replace the panel on my other LE 7070.
