Hello! I suspect that our MPM AP25 has separation problems (poor stencil � PCB separation). I observe a lot of �dog ears� after print stroke. And this is 100% machine problem, I�m sure. What machine parts should I check first time to avoid separatio

From what I remember there is a "snap off" setting in the AP25, where you can set the separation speed & I think it may also vibrate the board a little.
