Two part question re: motors and fault

[eodjeep2000]

After finally getting everything up and running it looks like my x-axis motor may be dead. (It made it about 1/10 of the way through my first part and just quit). In the event I have to replace it I'd like to just go ahead and replace them all with the best sized NEMA 23 motors that I can use on my next "and larger (4'x8') " multi-use table project and with my g540. I'd like my next table to be able to perform routing, minor milling, and plasma cutting. It'll be fairly heavy and I'm planning on a rack and pinion style system. What motors would you recommend?

I guess in short my question is, "What are the biggest steppers that the g540 can safely run?" and "Does anyone have ideas why a motor would just stop working (no faults or anything indicated, wiring seems intact)?" I'll troubleshoot more tonight.

Before deciding that your motor's at fault, turn everything off and let it sit for a while (to discharge the capacitors), then switch the leads from the X axis motor with another motor that's working okay. Then see if the fault follows along, in which case it's likely a problem with the drive, or if the same motor still doesn't work, confirming your first theory. If it's the drive, Gecko might fix it for you for free. They'll also be happy to recommend a motor suited to the G540 - probably because so many people ask this question, they've started carrying them themselves.

Yeah,

I did that as soon as I got home. The motor worked when hooked to the y axis. Now I'll check the wires after it sits a bit but it looks like I may be facing a broken brand new g540...which would suck alot.


edit:

Wires checked out just fine, looks like it's the board. Any other ideas?

edit #2:

I reconfigured the board to run my x axis off the unused (so far) a axis. It worked just fine which seems to confirm the G540 x-axis is dead..
