Here's the information as best as I can describe it;
1. Booted up our 5-year-old shop built 4 axis hotwire this morning and the power supply popped with the accompanying burnt electronic smell.
2. I replaced the 48v power supply with a similar model.
3. everything fired up again but when I tried to home the machine it went the wrong direction, X motors only for 1.0797 inches and then disabled, that distance repeats every time, Y motors didn't move.
4. I can flip the direction of the home direction but it responds the same way in the other direction
5. I can jog in both directions and it will run g-code programs, all in the correct directions.
6. The proximity home switches are functional but the g540 won't recognize them, even when you jog over them.

Any suggestions would be appreciated, thanks
