Just found this pic. Notice the grounding point. There must be a reason for it...

did some cuts yesterday and today . The new cable fixed the accuracy up to 30%, but still is not fully functional.
Stahlwerk plasma did the last cuts on my workshop today, as i sold here to a guy that builds truck trailers.
Next week i'll dismantle the whole machine and send it to Tommy's workshop to change the electronics,cables and Z axis.
I'll try to keep You updated as we get rid of these problems of accuracy i had for 1 year , it started to get mental issue  literally slowly destroying my brain cells.
kind regards 
Shpat
