CNC controller blowing fuses...please help!
« on: July 05, 2022, 11:56:26 AM »
I have a CNC Router Parts Nema 23 control w/ESS.  this system uses a toroidal transformer, 2 x 115vac primary with 28v Ac 8amp and 8v Ac 2amp secondary's. when i power up the machine the 2amp fuse after the transformer and bridge rectifier keeps blowing, this is the side that powers the proximity sensors. i cant find any loose or broken or grounded wires. this happened 2 years ago when i moved the machine and i simply replaced the 2amp fuse and been running fine. well, i just moved again and this time the fuse blew again and the problem is here to stay. i am desperate for help as this is how i make my living and the support team at avid cnc only want to sell me a new control system, very frustated. thank you in advance, Dan
