hi,
Got it to work. There was issue with bent contacts in one of those sockets.
Thank you for the advice.

Hello

I am having problem with my extruder motor, could you advice me on how to solve this issue please.
I have built Hangprinter with Duet 3 6HC and five stepper motor. Four Nema 23 for A, B, C, D motors and a Nema 34 for the extruder. All the motors work when i send g.code command except for the extruder motor. It seems Web controller doesn't recognise the extruder driver as the extruder controller on the Web Control is grey. I have check the connection and the motor itself and they are working.
Below is my config.g and the set up of the wire connection I have at the moment.

Thank you
Sophia

@dc42 hello
thank you for the info. I will use V48. would V48 goes in the range of the power voltage well below the stepper driver rating of 60V?

If I use one NEMA 34 and four NEMA 23 together with the Duet3 6HC v1.02, would the correct/sufficient voltage will be distributed to the stepper motors by the driver? e.g V48 for NEMA 34 and V36 for NEMA 23

Thank you. Since the input voltage is the output voltage, I just need to make sure to buy the Duet 3 Mainboard 6HC with version 1.02 or later.

Is it possible to have an external power supply or a higher voltage than 48V for the stepper driver? As the maximum voltage the stepper driver can handle is 60V?

Hi, In the Duet3 documentation (https://docs.duet3d.com/Duet3D_hardware/Duet_3_family/Duet_3_Mainboard_6XD_Hardware_Overview) have read that the maximum voltage intput for Duet 3 Mainboard 6HC v1.02 and later is V48. Not 32V. Is the version written on the board? How do I know which version I would be buying?

I am hoping to use a stepper motor, either NEMA 34 or stronger, with the Duet 3 Mainboard 6HC. Does the board have the same output voltage as the input?

If not, can I add an external power supply to the stepper motor?

hi,

Sorry about the late reply. Thank you for the advice. i've sent M302 P1 and then G1 E2000 F1000 it worked.

It's a bit of a different question is it possible to bypass the homeing function? I am printing a shape on top of the printed shape. And when I tried to print the second shape on top of the first shape after the first shape was finished, I got an error saying, "Error: G0/G1: insufficient axes homed". I could send G92 X0 Y0 Z0, but wouldn't this command make the printer think its position is the home position in the config.g? making it poor calibration?

Here is my config.g file. I have commented out the heater, fan and thermistors as I don't have any of them. With M302 P1 command, if it works with my config.g sending e.g M302 P1 G1 E500 F1000 will retract the extruder?

Hello

Recently i have been testing the clay extruder connected to the Driver0 on Duet 3 Mainboard 6HC. I have been clicking the 'retract' and 'extrude' button multiple times to push the plunger down to the correct position and to retract the plunger from the bottom of the cylinder after the print. Is there a command/G-code I can send instead? I've tried G1 E500 F1000, but nothing happened.

Here is my set up.

Best

hi,
Got it to work. There was issue with bent contacts in one of those sockets.
Thank you for the advice.

Hi, Thank you for the advice.
I have managed to changed all the address of the 1XD and they all work when then are individually connected to the main board. But when i connect then all four of them together, first two works (first image), LED from them sync with the main board and i can find them through DWC. But the other two 1XD board doesn't work. LED from these boards flash rapidly and continuously. I believe the wiring is correct. could there be another reason?

Hi,
I have Duet 3 Expansion 1XD connected to Duet 3 Mainboard 6HC.

DWC wasn't recognising the 1XD, I thought i has something to do with can address, so I have tried to reset the 1XD to factory setting with jumper. But i don't think it got reset as during the process, I got LED behaviour and error codes - 4 times flesh.

The power of the main board is fine, and the status LED on the main board works, flashing per second. I think the CAN connection between the main board and the expansion board is ok as well. This is RJ11 I am using. it is not the High-Speed ADSL cables but i read this is not a problem. When I tested it with a cable test, it worked.

when I restarted the board without the jumper , status LED on the 1XD was flashing continuously and rapidly. DWC doesn't recognised 1XD.

What can i do to fix this?
