You will connect one Z motor to the Z1 (drive 2), put the jumpers back in the second port. Then connect the other Z motor to the E1 (drive 4)
For bed.g you'll also have to find the points to probe with G30
G28 ; home M401 ; deploy Z probe (omit if using bltouch) G30 P0 X20 Y100 Z-99999 ; probe near a leadscrew, half way along Y axis G30 P1 X180 Y100 Z-99999 S2 ; probe near a leadscrew and calibrate 2 motors M402 ; retract probe (omit if using bltouch) The G30 P1 will likely be further to the right on your larger bed so adjust the CX position accordingly.

Thank you very much for all your help. I will make these adjustments tomorrow, but how can I find points in M671 coordinates of my own bed measuring, is their sort of documentation can explain how to find the coordinate positions of my bed. thank you again
-
You just need to choose a point close to the lead screw but still on the bed and both need to be in line on the Y axis.

THANK YOU. it worked and I found my correct bed coordinate points. do I have to change any config for my BLtouch current settings are
Z-Probe
M558 P9 H2 F120 T6000 ; set Z probe type to bltouch and the dive height + speeds
G31 P500 X0 Y0 Z2 ; set Z probe trigger value, offset and trigger height
M557 X5:350 Y5:350 S50 ; define mesh grid
I have version 3 -
The dive height is a little low. It should be at least a mm more than the trigger height. Try M558 H3
Also change G31 P500 to G31 P25
Have you calibrated our probe and measured the offsets yet?

so I have adjusted all the settings accordingly here's a photo of the hight map
so I don't if that's ok or it should be 0 all the way I tried to print a file 340 x 340 and it looks like it's not adjusting probably. here's my updated file config.g; Configuration file for Duet Maestro (firmware version 2.03)

G29 S1I don't know if i have to enable some settings to run hight map while it prints maybe from slicer or from DWC. thank you for all your help
-
when I run G32 here's the message I get
does that meat its successfully calibrated. -
also here's the message when I run G29.
please let me know if that looks good sorry I know I have been asking you a lot. Thanks again -
Print a test file like this one with mesh enabled and again disabled. You should be able to tell if it's being applied correctly.
-
Yes I did what you told me and it looks like its not working properly. Any other suggestions would be helpful. Thanks
-
@moe-adams9093 What slicer are you using? Please post your start GCode from your slicer.

G31 P25 X0 Y0 Z1.758
You need to measure your X and Y probe offset otherwise the corrections will be off in X Y position.
The heightmap itself looks ok. After measuring the offset redo the G29 and reprint the test file to see if it's behaving better.
-
Thank you for the additional information so my x offset is 44mm and the y offset is -5mm but when I try to run mesh compensation its starting from 44 to 285 and my actual build volume is 350 x 350 so please correct me on that one am I loosing that left over space since it only probing from 44 to 285. Also when I checked my old configuration from the original bord it says offest x0 y0 z1.78 so I don't if that does matter or not. Please let me know thank you
