Request for dc42...

Post by geneb »

Could you add the ability to specify a speed parameter when you're specifying a thermostatic temperature with the T parameter on the M106 g-code? I've noticed that the PEEK fan can push so much air that the hot end can struggle to reach & maintain temperature. It would be nice to be able to dial down the fan speed. :)

tnx!

One solution might be to stick a resistor inline... or even a speed controller like this http://www.amazon.com/DROK-Controller-E ... B00CGXJSNY

Since Chances are the "always on" fan output is probably tied directly to the duet power input. Unless you actually meant Layer fan as opposed to peek fan?

The firmware the Duet uses can activate a specific fan when a temperature threshold is reached. This is done via the M106 code. (This feature is hard-coded in the SeeMeCNC fork of Repetier Firmware.)

You can read about how M106 works here: http://reprap.org/wiki/G-code#M106:_Fan_On - look at the "H" and "T" parameters.

I have added that to the wish list of future firmware improvements.

Question: Do you have the always-on fans set to turn on at a specific temp or are you using the pwm fan pins?

The "always-on" fans are just that - always on. There's no method (that I'm aware of) to control them.

For anyone who hasn't been following recent firmware released, this feature has been implemented and working since release 1.13b. I have set a minimum PWM of 50% for fans in thermostatic mode.

How do you configure it? just with the M106 command?

THANK YOU!

Nylocke, try adding the T parameter and see how it goes.
