Extruder E1 not working
-
@jackd2282 I hooked up my new bondtech ddx and my guess is that the motor was wired wrong cause it got hot then the driver burned

Driver 3: position 0, temperature-shutdown! short-to-ground, standstill, SG min/max not available
Driver 3 is definitely damaged.

Warning: motor phase A may be disconnected reported by driver(s) 4
Warning: motor phase B may be disconnected reported by driver(s) 4 with multiple
with multiple stepper motorsAnd it sounds like you still have the motor wired incorrectly.
Carefully identify the motors phase pairs first before wiring them up again.

@phaedrux I made sure the phases are right and tried all 4 combinations on the motor. No luck. Maybe E1 is also damaged?
-
Possibly, or the damage to driver 3 is also preventing driver 4 from working.

Can you provide some photos of the board? Especially close ups of the drivers?
Do you notice any damage or pock marks?
-
@phaedrux it was physically burned and not dremeled out
-
@jackd2282 I don’t know why driver 4 would be affected though. It wasn’t even hooked up when this happened but back to my question on the expansion boards, would that bypass this problem?
-
Well yes, if you added an expansion board like a Duex or external driver expansion board you could use the drivers on that as replacements. Just map the extruders to the new drivers with M584.

I'm not sure, but I think if the damage was bad enough it may have damaged the SPI bus which could cut communication to further drivers down the line.
-
@phaedrux that would make sense why my xyz still work
-
@jackd2282 ordered the expansion board so will see when it comes in
-
@jackd2282 ok so I am thinking that the expansion board may not work. It’s not here yet but I was taking for granted that my other drivers worked because they did before all this. But that’s not the case. None of them do. Same problem phase a and b. I tried just the z and modified the config.g to only include that drive and nothing. My board may be shot and that sucks cause I just bought that expansion board with next day shipping for nothing. None of them get warm. No errors unless I try to move a motor. I tried resetting the firmware on the board and card to just start over but no luck.

Did they work before but not anymore?
-
@phaedrux they worked before the extruder problem but I was so focused on that that I didn’t even try them.
