What kind of fans you got there?
I have been building my first CNC machine over the last couple of weeks. Tonight I ran the motors through a couple of parts for the first time. Man, this is sweet. I have attached two pictures of the runs. Not much to see, except for some really cool fans on the control box.
PC cooling fans I purchased from CompUSA for $8 apiece. They have three LEDs in the fan area to light them up. They are 12v so I ran them in series off 24v. Works good.
