C coupler direction.
-
What are all the ways I can try to change the motor direction. I tried changing the wiring and changed the M569 P7 S0 to S1 and tried changing my endstop from high to low with.
I am having trouble homing my c coupler. I think im over heating it. sometimes i can trick it and make it unlock and lock but after 2 or 3 it starts acting like an extruder and only goes one directionBoard: Duet WiFi 1.02 or later + DueX5

Are you really changing M569 P7 S0 to S1? Your config says your "C" axis is using P8 so shouldn't you be adjusting the direction on that one?
-
Im all over the place. I changed to 8 to see if it was the driver, just said it wrong. is that supposed to change the direction? Im rustry i first built my printer over a year ago.

I dont know how to link a thread but i tried this allready.

If your C motor will only go one way, it could be that one of the phases is disconnected, because of a burned out motor winding, bad crimp connection, or faulty driver on the Duet. Try the following:
Use G92 followed by G1 H2 Cxx moves to test the motor and driver, with both positive and negative C values
Measure the resistance of the motor phases between the pins of the Duet motor connector (with power off of course).
If they look correct then try swapping the motor output with anther one, using M584 in config,g to swap them in firmware too (don't forget to swap the values in the two M569 commands too).except the resistance. Do I just check to see if the have the same resistance.
I order a new motor. wont hurt to have a spare if its not it.
also when i had it at 60% it only turned 1 direction but when i went to 70% it went both ways but still backwards.

Yes, check the resistance of each phase if you have a multimeter.
What C motor current are you using (M906), and are you modifying it at all using M913? I understand that the coupler motor needs to be run at or slightly above rated current in order to work reliably. Running it slightly above rated current for the few seconds needed it operate it is safe, provided that the current is reduced the rest of the time.
-
I got .001 on one set of leads and .003 on the other. I had it set to ohms where it beeps. i got a beep on both leads. thats at the end of the extension wire threw the connector.
I have the M906 set to 400 now cause i didnt know the best way to reduce it before i ran the homec. I know it reduces after an unlock or lock. do i put an M913 after the M906 in the config.
Is there another way to reverse the motor.

Is there another way to reverse the motor.You can swap rotation direction by either swapping the phases at the pins, or specifying the direction with M569 S in config.g
M913 is a modifier for M906, so M906 must come first in config. M913 would usually be used in a macro to scale the current to a percentage of M906
