Re:Dahlgren Engraver Z axis air actuation

The buzzing might be from the wall-wart, they are often not the most stable or well regulated supplies.

Do you have any other power supplies you could test with? (Black and Red on a spare hard drive power plug in the PC, for example)

Rick,
Good idea.
I will try switching pins and see what happens.
thanks

Andy,
Thanks for the idea, it did not occur to me to get clean 5v that way.

A spare USB cable would get me good 5v also, right?

I will give it a try.

Not sure how much power you need for the relays but the usb is limited.
But of course find the location of the problem with testing.

I got the engraver working from EMC
here is one of my first tests...


currently I am working on the CAD/CAM end of things...
Nick's gcode tools in inkscape looks promising!
I am also playing around with some .py scripts within AXIS

Glad to hear you are up and running!
