@dc42 Thank you!
Last question: is the Duex2 jumper removal necessary for using both DueX5 and expansion breakout board? I would like to use Drives 5-7 on the DueX5, and Drives 8,9 on the expansion board.

@o_lampe I appreciate your suggestion!

@dc42 I appreciate your help!

For the current setup, just one external driver. The DueX5 controls two steppers and some fans. Duet2 controls 5 steppers.

Please clarify connecting a DueX5 and an expansion breakout board to the expansion ribbon cable. Simply connecting a 50-pin ribbon to the Duet2 that has two 50-pin outputs? Will the same drive numbers 5-9 apply, but can only use one of the same drive number?

For instance, I assume if I have extruder steppers on drives 5 and 6 (DueX5) and an external driver on drive 9 (expansion breakout board), I can refer to them as E5:6:9, and the firmware will know whether they are plugged into DueX5 or expansion. Is this correct?

I will also attempt connecting the external drive using the Duet2's CONN_LCD, as I read in the forum. In that case, are the three negative signals (DIR-, PUL-, ENA-) connected to the same GND pin (e.g., "2)GND" under stepper channel 10 & 11)?

The CONN_LCD approach may work for now, but using both DueX5 and expansion would be very useful as the next stage will require at least one more external driver.

Much appreciated! Thanks for the great products! They have been so valuable for my research.

Hello,

My printer uses an iHSS57 Integrate Stepper Servo Motor that requires 3.6V differential signals on ENA-,ENA+, DIR_,DIR+, STEP- and STEP+.

I used the Duet Expansion Breakout Board for this successfully (along Duet2 Wifi). However, my new printer needs the Duet2 Wifi and the DUEX 5 EXPANSION BOARD. How can I connect the iHSS57 in this case?

I appreciate the help!
