So my fan cooled TinyG box is done and installed.

So my fan cooled TinyG box is done and installed. I plugged in the fan but not sure how to make it turn on and off at the temp I want or?

Or, what if you turn it on at the start of a job and at the end automatically? What you could do is use the GPIO widget in ChiliPeppr. Then make a macro that watches the play/stop pubsub signals and send a GPIO command when you see those. That way CP is your glue.

You may want to get a ‘filter’ of some kind. Before I moved everything off the machine to a wall unit. I had my controller in a box under the machine similar to what you had. After every job it was filled with dust. I had the fan pulling vs. pushing exactly how you have it in your pictures above.

I just plugged the fan onto 12v fan plug on the tinyg board. It runs all the time.

Yeah mine pretty much runs the whole time I’m cutting. We’ll see about the dust issue, The dust collector boot I printed gets all the dust first I hope. Not much blowing around.
