Hi Folks,
I have searched fruitlessly up to now for a suitable circuit and thought I would pick your collective brains (again...lol).
Basically all I am trying to do is have a variable speed control for a wood router/laminate trimmer/PCB drill type motor.
I know some people are using light dimmers but laminate trimmers can draw up to 4 amps in use and I am not sure if a simple lamp dimmer would handle that. Running motors on lamp dimmers can also generate big spikes apparently and generally they do not last long.
As this will be used in a home-built CNC engraver/router/PCB mill I don't fancy having large spikes around stepper motors, computers etc.
Does anyone have a link to a suitable controller, or has anyone here built something similar that they would be willing to share?
This project is an extremely low budget affair (more to see if I can do it than anything else) and if I can build a controller so much the better. I am already 'dumpster diving' and ebay searching for materials....lol.
Thanks in advance for any pointers/help.
