Welcome to the SeeMeCNC Community

Long story short, I had to take apart the EZstruder due to a weird filament jam. Got it all back together, connected and turned the RoMax back on. I reached to add filament into the EZstruder and got a shock on the motor casing. I didn't think anything of it, not thinking it'd carry down and do any damage

I sit down to start doing some more calibrations and tinkering with settings in Rep-Host for Mac when I see I no longer can connect to the printer (I'm on OSX mavericks). So, just in case I plugged in one of my Arduino Unos and was able to instantly see it connected in Arduino IDE...

One of the threads on these here forums suggested unplugging stuff to see where death may have occurred. Sooooo, I powered the RoMax down and unplugged the extruder stepper motor to start with, powered it back up and boom! I'm able to see the printer again and connected right to it in Rep-Host for Mac.

So, my question is, what do I do now? Where do I go from here? We have some NMEA (not 17) stepper motors at work I can grab for testing but they don't have matching cable/pins, so I'm a bit apprehensive to go that route. What should I do?

Halp!

Thanks.

Clarify. What kind of shock? Did you shock it with a static charge, or was there actually a high voltage on the housing of the stepper? I'll assume you meant static.

My guess is the stepper motor itself is fine, electrically they're just a bunch of wire coils. Since it was working before, I suspect your wiring is ok too. Extruder port damage is most likely, if a power-cycle didn't fix it.

Have you tried plugging the motor back in? Or one of the XYZ motors in the extruder position? You should be able to figure out if it's the motor/wiring vs the port itself quickly enough. If it's the port, your solution is likely to be making the software changes to use the other extruder port.

Eric,

Correct, ESD all the way when I touched it.

Last night after I posted this I remembered I could use the other extruder port, and your confirming that made me so happy.

I'll try one of the other motors in the current extruder port to verify port or motor damage and will go from there.

Thanks much,

@Eric,

As far as software changes go to ensure E1 instead of E0 is used (if that ends up being the issue+solution), am I making firmware changes and reflashing the Rambo.. or just changes in Rep-Host?

EDIT: nevermind, yes, firmware change after doing a simple forum search..
sorry about asking a redundant question.. too much lazyweb exposure recently.
