What lines to change?

@tecno As I asked above, have you ever had your motors/drivers working with your current control board at all?

Mini5 eth + 3pcs 1XD to DM556, so not with that configuration.

@arnold_r_clark

Can be done but the motors need high current so the Mini is not up to the task

Missed G91

But still no movement

It could mean that the enable polarity is wrong. Some questions:

How did you wire the external drivers to the 1XD boards?
Before you power up the drivers and the Duet, do the tower carriages move freely?
After you power up and before you send any commands, do the carriages move freely or are they locked?
After you command a motor using a G91 G1 H2 command, does the carriage move freely or is it locked?

Thanks. Your wiring link suggests that you have connected the Enable inputs of the drivers to the 1XD boards. So if you have set the Enable polarity correctly, the carriages should move freely before you command them to move, and after that (or when you use M17) they should lock. The fact that they are not locking suggests one of the following:

Power is not being supplied to your external drivers
Motor is not connected correctly to external driver
Configuration of external driver incorrect
Configuration of RRF is incorrect, so that it is not commanding the 1XD boards to move the motors

Please run the following command and report any error messages that you see:

Have been trying to search the forum what this Setting not available for external drivers is caused but cannot not find anything.

@tecno Have you tried removing X, Y and Z from your M906 command, you can't set the current for external drivers.

@gloomyandy

Now I did that = still no movement. Error in M98 gone

With my DMM I can measure DIR shifting 4.78V to 0 and see a small shift in Step of 0.048V and EN is 4.78V

Even tried to shift driver to DM542A No movement on Y axis

Now all axis are connected to Mini5, only E0 is moving.

You've got the numbers backwards I think.

The first digit is the board address, the second is the driver number.
