IF the two are identical, swap the suspected bad one (#2) position 1, and see if the fuse blows before connecting the second one. Basically the same test process you describe, but swap the units first. See if the problem follows the card, or stays

The ribbon cables might be shorting. Have you replaced them?

We are having a problem right now where the machine won't load the circuit boards (mot m, y, z, etc) due to the machine blowing the fuses. This was diagnosed by one of our engineers to be a problem with this part: MyData MyCronic Booster BNB/NREG L-0

These were all great suggestions and helped find the issue; we ended up replacing the Mot M board which made it work.

I know this is an old one, but we still have problems on our heller oven with parts blowing off their pads. Our other oven does not do this and it is a conceptronics oven. We do not currently have the adjustable fan speed on our heller oven. My q

I could really use some help, My oven is continually blowing one of the SFC fuses (the one on the left as it sets in the machine) when the conveyor tries to run. It appears that the traces on the circuit card were having too much current pulled th

Have you done a post-mortem on the blown fuse? Assuming it is a glass fuse, if it is all black around the glass then replacing the fuse will be pointless. (the new fuse will just blow again, making a black mark or BLACKER mark all around the glass)

There are temperature controllers that can be configured for a "safety stat" mode, so they blow a fuse to the main heater control if it goes, say, 10C or some reasonable fluctuation above the setpoint. It might be a VERY reasonable thing to add to y

It could be the brake for the rising table. I don't remember if it runs on 44 volts but if it is bad it will prevent the table from moving and may blow the fuse.
