Problem with Duet 3 Expansion 1HCL board

AndersB

Hello,

Im building a Cartesian style 3D-printer.
The mainboard I use is the Duet 3 Main Board 6HC running RepRapFirmware 3.4.5.

I would like to run my x and y stepper motor on 48V so I got two Duet 3 Expansion 1HCL boards but I cant get this to work. ( I cant home the axis)

Have I conected it wrong?

Here is the config file: Config(G).txt

Maybe someone can tell me what I am doing wrong.

It looks like your firmwares are out of step. Update the firmware on the expansion board.

What is the nature of the homing issue? What is your homing file?

Now I have set the main board and the 1HCL boards to verson 3.4.4
I still have the same problem as before, the stepper motors will not run.

Any suggestions how I should proceed?

@AndersB your boards have a CAN address of 50 and 100 and yet you're using 121 and 122 in your config. Which is correct?

dc42

@AndersB you have reported these diagnostics:

M122 B50
Diagnostics for board 50:
Duet EXP1HCL firmware version 3.4.4
M122 B100
Diagnostics for board 100:
Duet EXP1HCL firmware version 3.4.4

which suggests to me that you have set the CAN addresses of the EXP1HCL boards as 50 and 100. However, your config.g file contains this:

M569 P122.0 S1 ; physical drive 122.0 goes forwards
M569 P121.0 S1 ; physical drive 121.0 goes forwards
M569 P0.2 S0 ; physical drive 0.2 goes backwards
M569 P0.5 S1 ; physical drive 0.5 goes forwards
M584 X122.0 Y121.0 Z0.2 E0.5 ; set drive mapping

which will only work if the CAN addresses are 121 and 122.

If you run command M98 P"config.g" then I expect is will report that it can't access boards at addresses 121 and 122.

@dc42 said in Problem with Duet 3 Expansion 1HCL board:

M98 P"config.g"

If I run that comand I get this:

Error: Response timeout: CAN addr 122, req type 6043, RID=18
Response timeout: CAN addr 121, req type 6043, RID=19
Error: Response timeout: CAN addr 121, req type 6042, RID=16
Response timeout: CAN addr 122, req type 6042, RID=17
Error: Response timeout: CAN addr 121, req type 6042, RID=14
Response timeout: CAN addr 122, req type 6042, RID=15
Error: Response timeout: CAN addr 121, req type 6042, RID=12
Response timeout: CAN addr 122, req type 6042, RID=13
Error: Response timeout: CAN addr 121, req type 6018, RID=11
Error: Response timeout: CAN addr 122, req type 6018, RID=10

So should I edit the config g file to:
M569 P50.0 S1
M569 P100.0 S1

The RRF config tool will not let me change the CAN adress under I/O Mapping.

@AndersB yes to changing the config.g

Thanks
Now everything works fine.

Thanks for the help.
