Z Axis stepper driver / motor query

[900turbo]

Currently configuring my printer using RepRap I have attached a screenshot from the Duet3D documentation. It does not mention the Max No. of drivers per axis for the MB 6XD , the motherboard I am using. The printer I'm upgrading is a Builder Extreme 2000 the Z axis uses 3 separate motors each with there own stepper driver. Can i use what i have or will there be a issue with it? I read the defining connected motors section to try clarify this but didn't really understand it.
If someone could clear this up it would be greatly appreciated , Thank You.

@900turbo treat the 6XD as the 6HC.

@droftarts another tweak to the docs required. this probably needs updating as the number of axis has increased IIRC

@900turbo Thanks, I'll update that page. The list here is a little more up to date: https://docs.duet3d.com/User_manual/RepRapFirmware/RepRapFirmware_overview#firmware-configuration-limits

@jay_s_uk Ok , Thanks for the help !

[900turbo]

@droftarts Thanks for the List , I will have a look.

@jay_s_uk I have included a screenshot of the RepRap site , How do I add my Z2 and Z3 drivers? When i click on + it will only add E0 ect...
Thank You.

@900turbo Thanks. I've updated the Configuring motors page https://docs.duet3d.com/User_manual/Connecting_hardware/Motors_configuring#drive-limits, and noticed the Heaters page was out of date too, so updated that https://docs.duet3d.com/User_manual/Connecting_hardware/Heaters_overview#heater-configuration-limits

@900turbo you currently can't. there is a revision of the config tool coming that allows it but I don't think it'll be ready until the release of 3.5

For now you'll just have to edit the config manually afterwards.

Assuming you're using drivers 2 and 3 for Z, the only changes you need to make are to M584 e.g.

M584 Z2:3

@jay_s_uk Okay I see , so for now I will just config Z1 for the "starter pack of code"
Thank You.

[droftarts]

@900turbo You should add M569 commands for each additional driver, then M584 to define which driver gets used for each axis. See https://docs.duet3d.com/User_manual/Connecting_hardware/Motors_configuring#using-more-than-one-motor-on-an-axis-with-a-separate-driver-for-each-motor for an example.

@droftarts @jay_s_uk
When selecting the Endstop Pin how am i meant to be deciding what to select from the list I have screenshot below.
Thank You.

[jay_s_uk]

@900turbo what type of switch is it? normally open or normally closed?

[900turbo]

@jay_s_uk I have set up my microswitches to be Normally Closed to avoid interference on the XY axis. However the Z Axis uses 3 Photomicrosensors with adjustable Flags https://docs.rs-online.com/9ecf/0900766b800b4c3a.pdf
Thank you.

[jay_s_uk]

@900turbo just treat them as io0.in and so on

[900turbo]

@jay_s_uk Okay does that apply to all Axis?
Thank You.

@900turbo yep
