Hi, I have an application for a RAMPS 1.4 board to which it seems idealy suited.
One part of the project has a need to control a small DC vacuum pump and I was thinking about using a relay driven from an IO pin, but I wondered if one of the heater ports could be used.
The motor only takes about 0.5A and being an inductive load would need a couple of clamping diodes to limit the back EMF spikes.
Does this seem a reasonable idea or am I on thin ice ???
Regards,
Dave
