alexus

Ive seen link for 3 motor setup for auto leveling (kinda) .... i have 4 motor hardware, each moor has build in driver. whats the easiest way to confure my setup to use full auto leveling? i have Duet 2Wifi + Duex 5
any advice?

Same as for 3 motor, but with one more motor.

tnx looks not hard :)))

do u know how to cpnnect drives to Duex 5 with external drivers (as my motors have build in drivers)
also some what related question BLEtouch i use was set up on extension port, now that port is occupied by Duex cable so i guess BLT needs to be connected else where some how?

@alexus I've updated the documentation to include a 4-motor setup. https://docs.duet3d.com/en/User_manual/Connecting_hardware/Z_probe_auto_levelling#examples

For BLTouch setup on Duex, see the Duex tab in the documentation here: https://docs.duet3d.com/en/User_manual/Connecting_hardware/Z_probe_connecting#bltouch

tahank you so much

now i need to figure out how to connect mottors with build in drivers and i can start testing all hardware ))

Do you have any details on the external drivers?

@Phaedrux
external (build in) divers just take Step Dir directly to motors

@alexus Depending on the version of the Duex board you are using (v0.10 or v0.11), you can drive external drivers with it. See https://docs.duet3d.com/Duet3D_hardware/Duet_2_family/DueX2_and_DueX5#using-a-duex5-with-external-drivers
Note that signal level will be 3.3V; often drivers require 5V signalling. Check the datasheet of the motors.

If you need 5V signalling, you can use the EBoB board: https://docs.duet3d.com/Duet3D_hardware/Duet_2_family/Duet_Expansion_Breakout_Board

You can also connect two external drivers to the CONN_LCD port on the Duet: https://docs.duet3d.com/User_manual/Connecting_hardware/Motors_connecting_external

@droftarts
i have 0.11 HW
but if its 3.3V and looks like only 3 dives supported i guess better to get regular drives for this project,,, (actualy i have dives just dont have right gears... so will just get gears less hassle
