Duet Wifi - Ender 3 - Motor cable
-
Hi Everyone,
Sorry if this problem was already posted but I didn't find any specific thread regarding this problem.
The problem is as followed:
I have an Ender 3 and installed the Duet 2 Wifi board. All my motors were installed (X, Y, Z, E0).
I used 2 of the black Ender cables, and changed the connector that fits the board with the delivered connectors.
I used 2 other cables (the colored ones) and also changed those connectors with the board connectors.I checked the polarity of all the cable which were the same and fine.
On my first start up, the motors with the Black Ender 3 cables worked fine, all smooth.
the motors with the other cables didn't move, and made a lot of noise.I checked the wiring, the motors, but that wasn't the problem.
I switched the cables, and tried the black Ender 3 cables on the motors that made the noise.
Now the motors did work just fine, and smooth.So I know that the problem is somehow with the cables. Polarity is fine, the only thing I thought was that the cables were maybe a bit to small. So I had the other 2 Ender 3 black cables lying around, I wanted a bit longer cables, so I cut off the cable in the middle, and soldered some wires, with a much larger diameter on them, to make them longer.
I tested those cables, and again the same problem. The original, unmoddified cables work just fine, the other ones, even with a bigger diameter don't work.
I've checked the resistance, I even dit send a High frequency signal on every cable, and checked the response on a oscilloscope. They are all fine.
I don't know if anyone has this problem, if so does anyone have a solution?
Regards,
AlexDeb.

Please check the phasing of the cable/motor combination. See https://duet3d.dozuki.com/Wiki/Choosing_and_connecting_stepper_motors#Section_Using_the_internal_drivers and the following section of the same wiki page.
