Hi fellas. I have a chinese cnc 3020 and my spindle a has become too weak andbive bought a new 400w spindle and installed it today and for some reason the board that I put in that came with the cnc blew up one of the capacitors. I cant figure out why. Any advice on where I can get a new spindle setup (preferably not chinese) would be appreciated and also any idea on why theb capacitor blew up. Thanks much for any advice. I appreciate it!
