two z axis motors

@heathharper said in two z axis motors:
Does this apply only to Duet 2 WIFI and Ethernet boards, or can I use this method on the Maestro board as well?
If so, can I use 3 channels to support 3 independent motors on Z using a Maestro board if I add the Maestro 2 driver expansion board?Yes, you can do that with the maestro and the expansion board.

Thank you @Phaedrux ! I will read up on it! I guess the reason that I wondered was that it says "Each Z motor must be driven from a separate stepper motor output on the Duet + optional DueX expansion board".
I took that to mean literally the Duex2 or Duex5 expansions, not just the added 2 stepper expansion for the Maestro.
If the 2 stepper Maestro expansion fits the "DueX" description, then this answers my question.

I've edited the documentation to include the maestro + expansion board.

@Phaedrux Wow! Thanks! Amazing support!

@heathharper Make sure you use RepRapFirmware version 2.01 or later, when support for the Maestro expansion board was added to the firmware. No reason not to use the latest 2.05.1 though! See https://forum.duet3d.com/topic/14425/extruder-motor-3-and-4-no-power-to-extrude

It should be pointed out that the motors will "run identically" until power is cycled a few times. There will need to be some means of resynchronizing them from time to time to prevent the X axis from tilting so badly that the machine can't print.

@mrehorstdmd True. @heathharper see this guide: https://duet3d.dozuki.com/Wiki/Bed_levelling_using_multiple_independent_Z_motors
This recent thread also covers it: https://forum.duet3d.com/topic/14486/independted-dual-z-manual-bed-leveling-assistant-question specifically my post here: https://forum.duet3d.com/post/133994

I'm going to upgrade a Cube Pro printer that has dual y-axis motors. Should i connect the 2 motors to use with 1 driver on the board, or is it better to use separate drivers? I read that the board features 2 Z motor outputs, so could i use these ports and switch z with y in the config? Appreciate any help

Did you read any of the replies in this thread?

it depends. if you have spare drivers on the board you intend to use then using two allows you to individually tram the two Y axis motors

yes you can change the drivers to use any axis in the config.
