I am working on it as-well. I was loosing total touch in the beginning running standard settings on the Vacuum lamination machine and then the autoclave. I now run the lamination at 1.2 on the gauge instead of the standard 2.7-3 and the plate drops extremely slow. Also I run it manually, I have the plate drop "watching it" and only let it laminate for 1-2 seconds then hit the "red stop". Now for the Autoclave I have turned it down to 2.7 from the preset 4.2 even though all the info available says 6.2 is OK. its way to high for the 6 from my findings.
This is as far as i have got and am not losing touch anymore. But its not perfect and i still think the polarizer need some looking into. Touch still works with this method. I hope to find the exact problem and solution soon. I only know what it is not. its not the conductive glue, its not the glass or OCA because some are perfect and others are not with the same material 50+ units tested. I encourage you guys to test at every stage, seek out the best quality refurbish parts and try to run your machines at as little pressure as possible. I am going to run another few units tomorrow and just keep turning the machines down till they will not work and then try to operate just above that threshold.
One thing is for certain the YouTube videos and the machines they are promoting are in no way addressing this real problem? Makes you think WHY?
