PLA Fan not coming on
I am using simplify3d and I have the Prusa settings file loaded. I have my PLA cooling set to layer 1 = fan 0% and layer 2 = fan 100%. I have double checked the connections on the RAMBO to see if the fan was plugged in correctly and it is. Before I have to go find a 12v power supply to test the fan with is there anything else I might not be thinking of?
Re: PLA Fan not coming on
You could always use gcode commands to turn the fan on(M106 P0 S255) or off(M106 P0 S0) through either Pronterface or OctoPrint terminal interface as a way to test to make sure it works and that it is plugged in correctly as shown (Print cooling fan):

And in case the RAMBo is malfunctioning, try putting the print fan into the Nozzle/Hotend fan(blue) port being careful to have the RED wire going towards the USB port and issuing the commands M42 P8 S255 to turn the fan on or M42 P8 S0 to turn the fan off. Provided your Hotend fan works, this would also turn that fan on/off (if you test before you swap).
and an 8 inch (200mm) or greater caliper is recommended.

Ok so the fan works correctly. I printed one of the stock files and it works great. I use simplify3d and I have the settings on the Cooling set. I cant figure out what I am missing in Simplify3d....
Re: PLA Fan not coming on
I ran the M106 on the Script tab in Simplify3d and now the fan runs all the time. I would like for it to come on after the first layer is complete.

Hmm, are you using the official Prusa machine profile? I wonder if your machine settings are somehow wrong and the correct gcode is not being generated. Perhaps you can post your S3D gcode here?

what should I be using under firmware config?

Yes straight from prusa3d.com
Re: PLA Fan not coming on
I just changed the firmware to Reprap/merlin/... and it looks to have changed the Gcodes so tomorrow I will give it a try.
Re: PLA Fan not coming on
The firmware selection in Simplify3d was the problem! Thanks 😀
