I have a LG Goldstar 610 that does not inject every shot. mold closes,half nuts close, but only reading about 500 psi. disconnected sensor for carriage fwd.now it injecting. also mold closes slow,then speeds up and slows down so fast machine rocks. Mold close VC1 set at 10%,VC2 0%,LS2 .02 anyone ever work on one of these?
