Motors doesn't work on drives from Duex 5

Phaedrux

Is this a new or existing Duex?

This is a "new" Duex, ordered it 13 months ago and installed it this week.

Eken

Tried with other drives on duex and remapped in config.g but the same LEDs behaves as before. Also swapped polarity on the motors.

It’s not that I completely missed some installation steps?
Because all I’ve done is connected the Duex with ribbon cable and VIN +/-.
I haven’t told the Duet there is a Duex in anyway if that’s necessary?

The Duex should be detected automaticially.

Did you check the fuse on the Duex?

Frederick

Eken

@fcwilt
Yea the fuse is solid.
So there aren’t a configuration step to let the Duet know I added a Duex?
That was one answer I was hoping for…

Did you measure the voltage at the power input to the Duex board?

@fcwilt
24,2V if I remember correctly, same as at the Duet and PSU.

Edit
24,19V

All I can suggest at this point is to disconnect everything but power and the ribbon cable then run M122.

Of course turn off power first.

And there is no need to perform a reset?
Necessary positioning of jumper?
No nothing to get the drive outputs active more than assigning them in config?

Noticed that if I disconnect all stepper motors the end6 LED turns off.
If I connect a motor on any of the drive outputs the end6 LED turns on.

Eken

@fcwilt
Ok, tried that as well.

With nothing still connected run M98 P"config.g" and see if any errors are reported.

M98 P"config.g"

I'm running out of ideas. Please post your complete config.g file using the </> tag.

Thanks.

Don't understand what you meen with </> tag?

@eken

Well you must have used it since the file is display correctly.

Clicking on the </> icon enters three lines of characters used for pasting code into a post. I've reached the point where I just type in the needed characters (two sets of 3 ` characters).

@eken

I don't see anything odd in the file.

It looks like the boards are mounted to a metal plate. If so, did you check for any shorts to the plate.

If not at this point I think you need to get @dc42 involved - you may have a defective board or ribbon cable.

@fcwilt
Ok, thanks a lot for your time and effort!
The board is mounted on brass extenders for PC motherboards, extra tall so there should be enough clearance.
Hmm maybe I can find another ribbon cable just for trying something…

I’ve never used the </> button, only knew about the ‘’’

fcwilt

@eken

Did you check to be sure there was no continuity from power in (positive or negative) to the metal plate?

Frederick

@fcwilt
Yes, nothing there.
