Dear CNCmakers, 
Thanks for sending the replacement fan.  
I had a question about our CV8 Machines. 
On the control panel there are buttons labeled User1, User 2, User3, User4, and User5.  
We know that User4 is the Door Interlock.  What are the other User buttons used for?
Thanks Again for the excellent customer service!!
