Thanks
Now everything works fine.

Thanks for the help.

@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

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.

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.

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

@alankilian Here is a link to the motors I am using

https://se.rs-online.com/web/p/stepper-motors/5350502

Hello
I am looking for some help with my home made 3-D printer. It is a Cartesian type printer with a build volume of 500x500x480mm.
It is driven by a Duet 2 Ethernet board. My x and y-axels are driven by ball screws with 4 and 5mm pitch.
The problem I have is that the motors to these axels stall when I try to print above 28mm/s. I think it is due to the back EMF reaching a to high level, but I am completely new to the world of electronic, so I am not sure.
The specs for the motors are as follows:
Specifications: Step Angle 0.9 Rated Voltage V 2.5 Current/Phase A 2.8 Resistance/Phase Ω 0.9 Inductance/Phase MH 2.5 Holding Torque Nm 1.26
What I am looking for is a motor that can handle 2000-3000 rpm without losing their position, and is easy to set up whit a Duet board. I don´t mind upgrading to the Duet 3 boards if that makes the wiring easier. Does anybody have some recommendation of motors and how to connect them?
I have been looking at the clear path motors, but I am not sure if they work with the duet or if they are hard to set up.
