Subject: Re: [Homebrew_PCBs] Speed control for laminator motor

The speed controll is not right idea.
They doesn't help. Even worse.

When I put PCB in laminator I need aprox 6 times to repeat this to PCB
get hot enought.
If you observe laminator the roller inside does not have heater. The
roller is heated by heater mounted by side of roller. So if we slow down
the motor then roller will cool down quick as the rubber has smal
thermal capacity. And the PCB radiate heat quick as it has big surface.
So the beter way is to speed up that motor and make more passes. .. but
I just live with original motor and speed 6 pass and modification in
temperature regulation (180 centigrades) it's just work.
If we want single pass work then the only way (with laminator) is to
preheat board.
