Hello,I am just getting started with FuidNC and learning as I go.
I managed to get all axis moving in right direction and homing proper.
Now I am printing a enclosure and planning wiring. I would like to ad a cooling fan and plan to use the fan1/fan2 outputs. The pin out diagram list these as IO147/IO148
How and were in the config do I activate these? And is it designed to come on at a certain point like when the laser is activated or steppers start to move? Or does it just activate when the controller is connected to lightburn etc.?
As you are intending to use this tinybee in a laser machine there will be no thermister to measure any temperature (as in a hotend in a 3D Printer setup) so having a fan come on when something reaches a certain temperature is out. You could use the PWM_Enable pin to switch a fan on when the Laser fires up or you could just take the easy way out and have the fan run whenever the machine is powered up…Or… It is a laser machine so maximum torque will most probably not be needed from the stepper motors so they could be de-tuned somewhat to reduce generated heat and not have a fan at all. The laser module will have its own fan and wont (shouldn’t) need any further cooling.
Thanks Mike all kinda what I expected but was looking for comfirmation.
Yes it is for a laser and the thought was since it was there and I have way to many spare fans… I could use it to cool the DM556/power supply enclosure I will be adding in once this is ready to install into a larger frame.
To much noise in the shop when I don’t need it, so was dreaming of it turning on only when the steppers kick in.
I will most likely do the easy thing and just wire it to turn on with everything else.
But lets say I could add a temp sensor on one of the driver heatsinks, is there something that would work for that setup sensor wise? To be honest I don’t really have a on/off temp in mind yet but would be welcome to input for that crazy waste of time!
