Roland cutting force problem

Hi guys,
I have a xr-640 roland 2013, single owner.

My issue started when performing PerfCutContours, on the right half side of the sheet (Control Panel side) stickers where cutting at the right force. On the left side maybe 13" in some stickers where cut not with the same force. The problem seems to be increasing as time went on working its way to the right side of the sheet.

When doing test cuts on unlaminated film, I used to able to cut around 80 force, now I need to be around 145 just to be able to weed it.

I have replaced,
Blades, Blade Holders, Cutter Strip, Cut Guides and Cable, Cut Carriage Board and Servo Board, and today I replace the Cut Carriage Solenoid....

Roland Techs are stumped, I spent around 3,500 - 4,000 in last three weeks trying to get this going.

Anything else or time to buy a new one?

 

Would you happen to have that service manual to screen shot that page to us?

 

Thank for the reply. I thoroughly changed the strip 3 times in one month along with 5 blades and two blade holders just to make sure... Been running this printer doing perfs since 2013.... I know this machine pretty well. Not sure what is going, neither do roland techs. I'v been through three of them....
