H, I have been running a Micromill for a while and had recently converted it to Mach3 with a usb controller board.
However, having not used it for a while it suddenly stopped working mid operation.
It looks like it could be an issue with the 24V PSU as the fans turn but the door lock does not activate. The Siemens 6ep1 331 1sh01 only seems to be supplying a varying output voltage of 1-3V. Fuses seem fine.
Is a failed Siemens PSU likely? I will buy a new unit if needed but wanted to check if others had had similar problems.
