Error: M115: Response timeout: CAN addr 121, req type 6024, RID=30What puzzles me is that B122 in the middle of the CAN signal way is OK and start / end is not OK.

@tecno Did you configure the CAN addresses for the other two 1XDs as described here? https://docs.duet3d.com/en/Duet3D_hardware/Duet_3_family/Duet_3_Expansion_1XD#set-the-can-address The CAN address of each extra board must be set for things to work. Also make sure the CAN bus is only terminated by the last board in the chain.

Is this done 1 by 1, what about termination? Is it just to open cable loop?

@tecno Yes, power only one 1XD board at first, set an arbitrary CAN address as described in the link, and then move on to the next board. Repeat this step for each board.
The termination is set by the two jumpers behind the CAN_IN connector. Remove them unless it is the last board in the chain (i.e. no cable going out from CAN_OUT).

M119 reports no active endstop Hi or Lo

Have you configured any endstops?

@phaedrux
; Endstops
M574 X2 S1 P"!40.io1.in" ; configure switch-type (e.g. microswitch) endstop for high end on X via pin io0.in
M950 P0 C"40.out0" ; config output
M42 P0 S1 ; set pwm 100%
M574 Y2 S1 P"!41.io1.in" ; configure switch-type (e.g. microswitch) endstop for high end on Y via pin io1.in
M950 P1 C"41.out0" ; config output
M42 P1 S1 ; set pwm 100%
M574 Z2 S1 P"!42.io1.in" ; configure switch-type (e.g. microswitch) endstop for high end on Z via pin io2.in
M950 P2 C"42.out0" ; config output
M42 P2 S1 ; set pwm 100%But no point to go further if https://forum.duet3d.com/topic/28717/the-tower-motors can be solved now!
